Should Fail Be a Four Letter Word

“We don’t have enough failed sprints,” my boss said during his staff meeting. The comment was said completely out of the blue as the meeting was winding down and I have to admit it threw me for a loop. Surely not failing a sprint was a good thing right?

Our group was pretty new to scrum at the time, and I didn’t really know what he expected me to do. The comment wasn’t related to any of his managers, just a general observation. It was his way of saying that he didn’t think our teams were pushing the envelope hard enough.

Some years, and bosses, later I was sitting in on a planning meeting. The team would calculate available hours by adding up the man days for the sprint and multiplying by four (the number of available hours per day). They’d then compare that to the sum of the task estimates to get an idea as to whether a backlog item was achievable in a sprint.

The thing was I thought the 50% availability was a bit conservative. And, I could tell that the task estimates were padded too. So to my mind the team was running at a capacity of about 25%. OK, that’s probably unfair to the team, but you get my point. I bit my tongue at the time because an in progress planning meeting is not the place to tweak process.

But it reminded me of my old boss’s remark, and to his credit I couldn’t recall the last time that any of my team’s sprints had failed. It was pretty clear that the team was scared of failure, and that was translating into very conservative estimates, and excessive time padding. They’d lost that gung-ho frontier attitude.

The fact is, that to get the most out of a team they need to be encouraged to push themselves and be aggressive about what they can pull off the backlog.  But that will mean failure at some point. And if that failure has consequences they may not push as hard next time.

And remember, even thought you may not practice executive censure for failure, if they are a group of high achieving individuals -as these guys were- then just the fact that they’ve failed, and that their peers know it, is probably as bad as anything you can dish out.

So what do you do?

The official scrum process is that the team should be conservative in what they commit to, but if they have time left over then they should work with the product owner to possibly pick up some additional backlog items. To me this seems like a good litmus test of an engaged enthusiastic team. Make sure your scrum master is checking for this.

Looking back I struggle to identify the source of their fear of failure. It certainly wasn’t punishment on my part. We’d been through numerous management changes and had a new fire breathing VP, so that could have been it. In hind sight I should have encouraged a more aggressive approach to counter that cultural pressure.

And that’s the thing with self managing teams. While you inspect and measure their output and they optimise themselves appropriately, they are also subject to other pressures from the organisation. If you’re not diligent about inspecting all the results of the team they could easily be optimising themselves in a direction you don’t expect.

And the fact that they fail, or don’t, is another output that should be inspected as well. And never failing could actually be the less desirable result.

Developer Productivity, taking the bigger picture

My last post touched on developer productivity, and while we’re in that space we really should address the elephant in the room. It’s easy to take a micro economic view of productivity and pick away at individual issues, like I did in the previous post. The hope is that as you eliminate each problem the sum of your efforts will build up and eventually you’ll double or triple the productivity of your team.

After all that hard work, you might be tempted to measure productivity, and this is where you might miss the elephant. The elephant I’m talking about is that it’s normal to see huge variation in individual developer productivity.

Let me say that again. It’s OK to have one developer three, five or even ten time as productive as another.

Paul Graham introduces this idea in his Great Hackers essay which is where I first came across it. Sure before then I realised that different devs have different levels of productivity, but Paul introduced the idea that orders of magnitude of difference is not only possible, but it’s usual.

The next question that springs to mind is of course is that OK? Paul talks about individual productivity, but what’s the impact on the team of this imbalance. Is it healthy for twenty percent of the team to be producing eighty percent of the output.

The first situation you might compare this to is your archetypal gang of council workers. Six guys leaning on shovels, and one guy actually digging the ditch. But to continue the analogy, the situation you really have is more like a mechanised freeway construction crew. Different workers use different tools and contribute different things, and no one metric can properly measure the scope of an individual’s contribution.

Imagine if the productivity of each member of the aforementioned construction crew was measured using e.g. volume of dirt moved. The front end loader and tipper operators would leap to the top. The grader and roller operators who more than anyone else will define the quality of the road move mere fractions of dirt.

As much as it might be tempting to try to build teams of only high performing individuals. I suspect that such a team might well implode. I’m not suggesting that you should have laggards. But having solid performers and smart but inexperienced juniors is healthy. The best work I have seen from the senior devs was when there was a young up and coming junior snapping at their heels.

And don’t discount your good solid middle of the range developers. When you have an arduous and potentially dull merge to do that must be right they are your go-to guys. The senors will probably rankle at doing such a task and ironically do a worse job. These developers are the support network that allow the high performers the freedom to pick and choose the most challenging and engaging tasks.

So choose your metrics carefully. Counting lines of code might be OK for comparing teams over time, or maybe trying to identify external issues that might be affecting a team’s productivity. But it’s not much good for individuals.

And if you mold your team around a single metric, over time you’re likely to loose the diversity that makes your team an interesting place to work. Which will drive your high performers away faster than you can say “performance review”.

Engineers, meetings, motivation and the stand up.

Engineers abhor meetings. Scott Adams probably made his first million on that observation alone. But it’s not strictly correct.

In fact, engineers love engineering. They love creating, and anything that gets in the road of that is beneath contempt. Meetings are reviled, but so are performance reviews, surveys from HR, pointless e-mails from euro sales droids sent to the ALL-Company mailing lists… you get the picture.

So what about the daily stand up? Is there room for improvement there? I say yes.

There are some good aspects of the stand up, apart from the fact that because the engineer is standing up it feels like they’re about to leave at any moment. Personally I think that whoever came up with the concept of the stand up, did that on purpose. It doesn’t feel like a meeting, it’s short, and the engineers know exactly what’s expected of them. Also they can probably prepare for it in the walk from their desk to the room.

But the meeting interrupts their morning, and they have to give status.

Now we can’t do much about the status because that’s really what the meeting is for. Not so much for management because frankly I can get all the status I want from the system. But by giving their status verbally they’re making themselves accountable to their peers for what they’ve been doing. And while they may think that they can bamboozle their PHB, they know their colleagues will see straight through any dissembling and they usually won’t want to look stupid or lazy in front of their colleagues.

But the price of this daily accountability is the interruption of the meeting. And, engineers hate being interrupted.

Coding requires that a huge amount of complex detail is kept in short term memory. A single interruption can flush that detail, and once it’s lost it can take fifteen minutes to get back to the same point. Developers are at their happiest when they’re in that fugue state where algorithms are leaping fully formed from their fingers. But it takes time to get into that zone, and only seconds to be pulled from it.

That is why companies have meeting free days, or e-mail free days. Ideally creatives, engineers, writers and developers should schedule their time in four hour blocks if they’re going to be productive. For a manager, whose day is interrupt driven, this can be difficult to understand.

So that’s easy to fix right? let’s just schedule the stand up first thing. Except maybe you have flexible working hours. OK, you think, just about everyone is in by ten, let’s have it then. But then you realise that if you have it at ten you’re pulling the guys who got in at eight right in the middle of their morning.

For the early starters, this is the most productive part of their day. This is the only time they can code in peace. What is worse, if they know that a meeting is coming up at ten they may even choose not to start a big task because it will be interrupted in a few hours time. Maybe they’ll use that time to read e-mail instead. In a worst case scenario your choice of meeting time may well have halved the productivity of all your early starters.

My solution was to have the stand up just before lunch. In fact I had this policy for all team meetings right from when I first became a manager. If at all possible any team meeting should be between 11:30 and 12. The exception might be something like a big planning meeting that you know will take half a day.

The reason is simple. If the standup is at 11:45, with lunch looming the engineers are already in the mind set to take a break anyway, so it’s a lot less disruptive. They might make a phone call, or check a couple of e-mails afterwards, but they’re not going to start anything big. They’ve just had a good three or four hours of (hopefully) uninterrupted productive work and once they’re done with lunch they can get back to another substantial task without worrying about a meeting killing their afternoon.

The fact that you also unconsciously associate the stand up with food can’t be a bad thing either.

In the end the more uninterrupted development time you can give your engineers, the happier they will be and the more productive they will be as a result. You may not be able to control that spam e-mail from the euro sales team, but you can control when your stand ups are. The timing of a meeting may seem like a little thing, but to quote John Wooden;

“It’s the little details that are vital. Little things make big things happen”

 

Sometimes you just don’t have the right tool for the job.

Back when I was a young whipper snapper I’d often work on some project in my father’s shed. By project I mean some kind of adaption to my car like grafting a couple of Webbers to the engine. Dad had better tools than I did, so I’d often save a particularly nasty job for the university holidays.

Of course at some point something would go wrong, and a stream of profanities would issue out from under the hood of my car. Dad would wander over and look at the rounded nut, or stripped thread or whatever problem I’d created and say, in his laconic bush drawl, “I dunno, maybe you could try XXX”. Invariably XXX would be something odd-ball like patching a cracked oil sump with epoxy, or using a pipe wrench to undo a nut. Something I’d never have thought of, but it would usually work.

Dad’s solutions were resourceful and creative, he’d developed those skills through years of farming, and growing up during the war when everything was scarce. Sometimes he just didn’t have the right tool and had to make do.

And, when you’re part of a large development organisation you need to develop that kind of mentality as well. There will be things beyond your control, and mandates you will have no choice but to comply with. On some issues it may be worth campaigning for organisational change, but for some it won’t and you have to pick your battles.

For example my last employer had an internal all-of-company bug tracking system. Now while this was not the most cutting edge or fully featured system, it worked. And, when there’s a lot of inter product integration and dependency, it makes a lot of sense to have all the development teams on the same system.

So what happens in that situation when you’re evaluating an Agile tool that has bug tracking built in but you’ve already got one. There’s three options;

  1. Buy the tool and don’t use the feature. This causes an awkward workflow and potential confusion. Not to mention loss of value.
  2. Use the feature and write integration to the existing system. This could be a lot of work.
  3. Limit yourself to tools that don’t include bug tracking. This reduces your choice.

This is just one example. And if you’re trying to implement agile within an organisation that already has processes, policies and procedures governing development you will be coming up against this kind of thing all the time.

One of the smartest things that an old boss of mine did was assign one of our junior Indian developers the job of tool automation. At the time his organisation probably had around a hundred engineers and there were twelve to fourteen sprints running across a number of products.

All that engineer did was write tools and scripts that integrated various systems like bug tracking, sprint management, wiki’s etc. His work allowed the tool we used for managing our sprints to smoothly mesh with the overall development process that was never designed for scrum. Sometimes he used API’s the tools exposed, and sometimes he had to query directly against a tool’s database.

Like the pipe wrench on the nut, many of the integrations were a hack but they got the job done.

So before you decide on using that all singing all dancing cloud based tool consider the kinds of integrations you might have to do. Then ask yourself how, or even if, they’d be possible using just the API’s they provide.

To return to the car analogy, if the hood of your car is welded shut there’s no way you’ll be able to bolt those Webbers on. And my car so needed those Webbers.

Metrics, the good the bad and the ugly.

For the last few weeks I’ve been involved with helping a start-up get moving. You may have noticed that I’ve been a little fixated on tools for the last few posts and that’s why. I’m currently choosing tools and procedures, which is a nice change from having them foisted on you, and I want to be sure to avoid the mistakes I’ve seen in the past.

The reason tool choice is important is because your tools define metrics you can collect. For this post I will focus only on the kind of metrics you might use when managing a Agile/Scrum team or teams. But the concepts are more generally applicable.

The internet is abound with stories of bad metric choice, setting pay rises based on the number of lines developers checked in is just one example. I’ll leave that kind of metric for a later post, if I ever address them at all.

But that example of a bad metric does serve to introduce some general principles for metrics.

They are;

  1. When a metric is gamed, it should still produces an outcome you desire.
  2. Metrics should be generated automatically using published methods.
  3. Metrics should be generated and published frequently, if not on demand.
  4. Metrics should be visible to everyone on the team or in the group.

I’ll discuss each of these concepts shortly, but in general if a metric does not satisfy those four conditions, it either needs to be replaced, or abandoned.

The first principle is probably the hardest to stick to. It’s hard because unless you’re a fool you’re hiring clever developers, ideally cleverer than you. They like solving complex puzzles and playing games. Any metric you create will be gamed. The lazy manager puts rules and policies in place to avoid the obvious gaming. This not only creates an us-and-them dynamic, but it also just makes the metric more complex, more challenging and thus more interesting to game.

A better approach is to anticipate the gaming, embrace it even. But this is not always possible. e.g. Years ago, during a bug-fix crunch period, before we’d adopted Agile, we had a product with a lot of bugs to fix to hit a release readiness milestone. We experimented with some gamification (that’s a topic for another post) but the practical upshot was that we offered prizes for the more days in a row that devs marked bugs as fixed. They only had to fix one bug in the day for it to count.

Now the senior devs could probably fix more than one bug a day, and we were concerned that they’d fix bugs and then sit on them, doling them out each day to get the maximum number in a row. But the thing was, over six weeks, we’d still get 30 bugs out of each of them, so why care.

The second principle is a little easier to stick to. It’s one of the reasons I’ve been harping on about ensuring that the tools you use can be queried and automated. If a metric is generated by someone counting the sticky notes on a wall, human error will always be a factor. Specifically, having a person generate a metric allows the veracity of the metric to be doubted. You can argue with a person and question their ability but you can’t argue with  the results of a SQL query.

The third principle is tied closely to the second. Only automated metrics can be produced on demand. Generally if a lot of human processing is required to produce a metric it might be produced weekly or even worse monthly. Imagine how useless a sprint burn-down chart would be if it was only produced at the end of the sprint. That metric is only useful because it’s reviewed every day by the team. The moment someone is having trouble it’s obvious and the team pitches in to help.

The fourth principle is probably the most contentious. Metrics influence behavior most strongly when the team can access their metrics on demand and they know that you, and their peers can also access the metric. Think of all the sales teams that have leaderboards, or call centers that show how many calls operators answer. It’s the visibility of the metric that makes this work.

But this is a two edged sword. If the metrics focus down to individuals then you most definitely get developers locally optimising their own numbers even if that’s at the expense of their peers. Software development is a team activity, so in general you only want metrics that are measured for a whole team. Not wanting to let your peers down is probably one of the strongest motivators you have. You can leverage this by measuring the whole team, not individuals.

What are some examples of good and bad metrics that are specific to sprint team management, I hear you ask.

  • Good: burndowns. As long as they’re generated by a system and not a scrum master with a spreadsheet. Putting it up on a dashboard or portal is good. But having every team’s burndown compiled into a single graph heavy email and sent out is the best use I’ve seen for a burn down.
  • Good: Bugcounts. Using the sprint starting point as a baseline is good if you need to focus on quality and your teams have a tendency to focus on the features and leave the bugs for later. This kind of thinking is common for teams who’ve been doing waterfall for years.
  • Good: Automated Test Counts and Coverage. Daily build results are good for this. As teams add features they should be adding tests and not introducing regressions. Even a simple percentage of code covered as generated by automated tools would work. Of course, beware of them gaming the system by having empty tests.
  • Bad: Story Point Consumption. This one is easy to get from most tools, and as a manager you might want to know for planning what your teams are capable of consuming but do you really want them cherry picking the easy backlog items to boost their averages? It also encourages shipping features over quality.

To sum up, metrics are about communication. They not only tell you what your teams are doing, they tell your teams what you care about. Careful metric choice can also encourage teamwork. When a team’s metrics are published they can’t help but compare themselves to other teams. So metrics need to be chosen with thought because like it or not they influence behavior.

 

Trusting a yellow sticky? Good luck with that.

Post it messAt one point as our group dived into our particular miss-implementation of scrum we had, as you would expect, one wall of a meeting room covered in yellow sticky notes. And we’re not talking here about a poky little phone room. This was the room we used for “all hands” meetings and for team pizza lunches. You could fit a good twenty pizzas on that meeting table and still have room for drinks and garlic bread.

That wall and those post-it’s managed the work of twenty five developers. And as I was shortly to discover, it was the bane of our scrum master’s life.

One day I wandered in to see what my developers were up to. I only managed one of the four teams at that point in time and the wall was great to see what my guys were doing. M (I’ve abbreviated her name to protect her right to anonymity) was sitting at the table, and even my stunted geek emotional radar could tell that she was seconds away from bursting into tears.

She was in the process of reconciling the wall with the bug tracking system and the escalation system. This took an inordinate part of her day and to add insult to injury she’d just discovered fluttering around under the table like autumn leaves, a whole pile of orphan post-it’s.

So I grabbed my laptop, sat down and helped her sort through the mess. Then for the next few weeks we would spend a good hour each day keeping on top of everything. It was the end of the release and our director and his peers needed the bug and escalation systems to be correct.

Now you would have thought that we should have been able to rely on the developers and the QA’s to keep all the systems updated. But when, as a manger, you’ve got processes that require your developers to update three different systems when they fix a bug, you have to take some of the blame for the inevitable mistakes and oversights. Hence I was helping keep everything straight.

Not long after that we abandoned the wall and it’s plethora of fluttering yellow notes. And eventually we managed to merge the escalation and bug tracking systems as well. As a learning experience it taught me not only to choose my tools more carefully, but also not to blindly trust the crowd. At the time the web was abound with people waxing lyrically at how post-it’s had transformed their development processes and we’d bought into that.

To be fair, if you have no formal development process, no bug tracking system and no feature management system then post-it’s would be an improvement. But when you do have existing systems, introducing a new manual system that has no potential for integration with your existing systems doesn’t really make sense.

In an enterprise it’s important to be able to back up your assertions with hard numbers. VP’s like spreadsheets. During planning you need to be able to say things like;

“Based on the last three months of development my sprint team consumes an average of 23 story points per sprint, with a minimum of 18 and a maximum of 27. Feature ABC is 100 story points in total so it will take at least 4 sprints.”

That can be used in a planning exercise. Saying instead;

“I think ABC will take about two months.”

Is just inviting your VP to order you to do it in one.

When your data is in a structured system that keeps history around the epic user stories, the stories they were broken down into,  the tasks they became, and the estimates at each step of the way, you have a corpus of data that cannot be argued with.

So what happens instead in the above scenario is that the conversation you have with the VP is directed to the feature set and what can be trimmed from that if a one month deliverable is a hard requirement for feature ABC. That is a more constructive outcome for everyone.

From previous posts you, dear reader, will have gleaned that I’m not an advocate of post-it based task boards. As a visual aid, and to motivate teams and provide accountability and visibility within the team they are great. But they are a one trick pony. You can’t usefully distill data from them for other purposes. You can’t integrate them with other systems, and you can’t see them unless you’re in the room.

Not to mention that post-it’s fall off the wall and get lost under the table.

Remote Working Shouldn’t be a Remote Possibility

One of my colleagues Anthony Langsworth has recently documented his experiences and opinions on remote working. He deals with it specifically from the perspective of an architect, an individual contributor, and I would agree with all the points he brings up.

Before I get to the purpose of this post I want to add that his point about video conferencing really resonated with me. A good setup, like the halo suite we had, can certainly substitute for many face to face meetings and could easily be used for a lot of scrum meetings. Unfortunately that kind of suite becomes a victim of it’s own success. Once our sales organisation became aware of how good the halo suite was, it was booked solid in that crucial two hour overlap that we had with the US office.

As Anthony says, try it yourself. I would add that if you can get a setup dedicated for your engineering department’s use, then by all means build processes around it, but don’t rely on it if you have to share.

But my purpose in this post is not to rail on about video conferencing. However it does introduce the idea of how, and in fact why you should incorporate remote workers into a scrum/agile team.

So why even bother?

There are several reasons why you should endeavor to include the facility for remote work in a scrum/agile team, or for that matter in any software development team.

The first reason to consider remote workers is that in enterprise scale organisations distributed teams are a fact of life. To get to the size they are most enterprise scale organisations grew with some level of merger/acquisition. That inevitably results in teams that are spread out over the country and indeed over the globe. In large organizations, outsourcing is a fact of life. So as an engineering director you will either inherit, or be required to develop, capability in India, China, Russia, or wherever else skilled labour can be had at a reasonable fraction of a US salary.

Even if you have all your engineers co-located, it’s inevitable that you yourself will probably report to someone on a different continent, or at least in a different timezone. You will also have shared engineering services like localisation, and architecture that you need to include in your processes. And let’s not forget technical technical support who will probably have some presence in at least three timezones.

So, if your development processes only support co-located contributors because they consist of sticky notes stuck to a meeting room wall, you are reducing your options for staffing, and excluding key contributors that make your product better.

The second reason to consider remote workers is that it gives you an edge in a competitive labour market. Unless you’re a merchant bank with deep pockets you can’t just buy the best developers. And if you want to keep your best people from being poached by organisations with more budget that you have, you have to change the game.

Usually in engineering organisations this is done by encouraging casual dress, having break rooms with X-Boxes etc. But working from home for one day a week is a privilege that is a lot more sticky. Not only can you equate it more easily to money, but once your staff have structured their family lives around it, they will think twice before taking a higher paid position at a much more conservative organisation like a bank. And sometimes that all you need to keep them.

I’m not suggesting that you should neglect your developer’s remuneration, but the harsh reality is that the only time in my career as a manager that I didn’t have to worry about competing with financial institutions for staff was during the first two years of the GFC.

The third reason to consider remote workers is because of a side effect that supporting them generates. Engineering is not only about engineers. You have to provide status up the management chain, and you need input from architecture, sales, support and product management. As I mentioned earlier in large enterprises you are unlikely to have all these on site. The more of your processes you can expose externally, the better your chances of getting the key people involved early. I’m not saying that everyone should see everything, what you expose is up to you. But if your processes are sticky notes on walls and you decide to email a daily scrum burn-down. Generating that e-mail will be a horrible, unreliable, manual process that will either send your scrum masters mad, postal, or more likely somewhere else.

What is the key enabler for remote workers?

Right, so you’ve seen the light and don’t want to rule out remote workers. You might have gleaned by now that I’m not a fan of post it notes on walls. As a way of introducing scrum, for small projects, and possibly in planning meetings, they are a fluid, tactile tool that encourages discussion. But for big ongoing projects you should use some kind of planning system like Version One, or X-Planner.

Your needs will vary, but as a bare minimum you should ensure that the system has the following features;

  • Some kind of backlog for user stories and a way to break epic’s down into items that are consumable by your team/teams.
  • Sprint task list management.
  • A back end database, or accessible API’s
  • (Optional) Automatic generation of basic status information like burn down and sprint summaries are useful both for yourself and your stakeholders.

The reality is that almost any system will hit this minimum list and in fact you will get a veritable plethora of additional stats and graphs and sprint planning, bug tracking etc. Before you start implementation ensure that it has sufficient API’s and hooks to integrate it with systems you have already in place that you don’t want, or can’t replace (e.g. bug tracking, or release planning).

The beauty of using an online system over sticky notes is that when a dev has competed their current task early (probably because they’re at home in a distraction free environment) they can log on and pick up another. Also, they can dial into the daily stand ups, and still get a sense of who is working on what. I have seen a junior dev pick up a task in a standup, only to have one of my principals chime in from the phone with an idea, or a request to review the code because they’re familiar with that particular area. They can do this when they have the task details in front of them.

Like bug tracking systems, and source code control systems, I consider an online backlog/sprint management system essential to the working of a well run software development team. And as long as it’s web accessible then your engineers and managers, who will be using it every day, can do so whether they’re at the office, at home, or on the road.

You’ll unshackle your developers from their desk’s, and you’ll get a number of other benefits as well, which I’ll go into in a later post.

NaNoWriMo 2011 Won!

A couple of weeks ago I wrote about my NaNoWriMo effort this year.

Well you’ll all be pleased to hear that I managed to win again. I passed 50,000 words with about three hours and fifteen minutes to spare, so it was a close thing.

Of course not everything went quite as planned. I’d hoped to finish the story a couple of days before the end of NaNo and then go back and fill in a couple of scenes to hit fifty thousand so I’d have a readable first draft on the 1st Dec. But as it was I lingered over the final chapter, it was enjoyable lingering, but it meant that I hit the magical fifty thousand in the penultimate scene.

So I still have a couple of thousand words to write to wrap it all up nicely.

Still, as an experiment to see if it’s possible to produce a readable first draft on the aggressive nano schedule I’ll call it a success. And the beauty is that I can distribute this to a bunch of Beta readers and get feedback as to what needs work before I put a lot of editing in.

Assuming that is I have any Facebook friends left. Having only posted NaNo count’s for the last month will have driven some away I’m sure.

The Absentee Product Owner

Invisible ManI’ve said before that large enterprises are each unique and have situations that your typical scrum cookbook cannot anticipate. Because of their size enterprises tend to centralise specialist functions. Product Management is one such function.

Before I delve into the issues, I had better define what my company calls a product manager. You will hear names like; Product Manager, Program Manager, Project Manager, and Development Manager used differently even within software companies.

Product Managers are responsible for determining the product direction. They talk to customers to determine needs. They put together road maps and do competitive analysis. They work with sales to find out issues blocking adoption. They work with Engineering to produce product requirements, and determine priorities. I suppose you could say that they are the public face of the product.

That sounds like the definition of a product owner in scrum right?

Yes, and No. Yes they own the direction of the product, but they’re not part of the engineering organisation. At least in Symantec they’re not. They have their own VP who is a more or less a peer with the engineering VP’s who are ultimately responsible for the products they produce.

They’re also not a large group. There would be about one Product Manager for about every fifty developers. Because they need to spend a lot of time with customers, it makes sense to place them all together in whichever region has the most customers. And here is where I get to my point, in large outsourced organisations, that will probably be a different region to the development team.

For waterfall this doesn’t really pose a problem. Product Managers do a lot of travel, and getting them out to the dev team two or three times a year for a planning session works fine. Time those trips right and Development Managers and Program Managers can then run the plan through to release.

But Scrum requires a more week to week involvement from the Product Owner. Planning sessions at the start of each sprint, and handovers at a minimum. Regular backlog grooming needs to be factored in as well. Scrum pretty much assumes that you’ve got the product owner on hand.

Let me tell you right now that we never really solved this issue to my complete satisfaction. But there are some things you can do to mitigate the effects;

  1. Do not use paper based sprint tracking tools like post it notes or index cards. You need to move to an all electronic form of tracking. Use Wiki’s like Confluence (http://en.wikipedia.org/wiki/Confluence_%28software%29) and requirements tools like Version One or Feature Plan.
  2. If you’ve got high end video conferencing available, by all means try it.
  3. Once the backlog is all electronic, backlog grooming can be scheduled as a weekly con call between Development Directors, Architects and Product Managers.
  4. Do everything possible to get the Product Managers to attend sprint handover meetings via con-call. Handovers are more structured meetings with a fixed agenda and are easier to follow over the phone. They should be less than an hour, and make sure the QA lead prepares a demo and uses screen sharing technology like Webex.

Planning meetings are too long and unstructured for a Product Manager to add value on the phone. It’s possible to get Development Managers and Architects to act as a proxy for the Product Owners for the planning and operational aspects of a sprint as long as they’ve prepared in concert with the Product Managers.

Before I close I would like to make one more observation. Even though the best mapping to the scrum Product Owner seemed to be  Product Managers, I’m still not convinced it was the right one in our case. In their role supporting sales, our Product Managers have never been as available to engineering as we felt they needed to be. Especially as in our case they were not co-located.

I find myself thinking back to the early Altiris days before we’d grown to the point where we needed a Product Management organisation. Our CTO, (later VP) performed that role, and did some coding occasionally as well. He was the very epitomisation of a scrum product owner. Unfortunately CTOs and VPs don’t scale. As their organisation grows they need to create a structure to delegate functions to, and unless that structure is created specifically with scrum or agile in mind we will always have this problem.

So be prepared to map the Product Owner role to several different people. And if you’re a Development Director one of those people will probably be you. Because as far as your VP is concerned you are the Product Owner.

NaNoWriMo 2011

Seeing as it’s half way through NaNoWriMo for 2011 I though I should do a post on it. Well, to be accurate it’s half way through and I’m still on target, which is the important bit.

This is my second year doing NaNo, I “won” it the first year I attempted in 2008 with a SF story that had been percolating in my head for a couple of years. I didn’t start in 2009 and 2010 mainly because I was traveling in November for both those years. If you don’t get off to a good start with NaNo on November the 1st, it is a struggle.

Others seem to see business travel as a good opportunity for time to write. On the face of it sitting in a lonely hotel, or more likely a lonely hotel bar, should be ideal for the creative process. Sequestering yourself works wonders. But despite my good intentions I never seem to get anything done when I’m traveling.

Not that I hadn’t been writing during 2009 and 2010. I’d added another sixty thousand words to the 2008 novel for starters. But those years just weren’t NaNo years.

This year however I decided that seeing as I knew I could do NaNo, I needed to up the ante.

First I decided that I’d step out of my science fiction comfort zone and instead write some literary fiction set in the present day. A character piece about a group of tango dancers who live in a small country town. Now I do know a little about tango, and I grew up in a small country town, so it’s not completely out of my comfort zone. And it’s also another one of these stories that’s been bouncing around for a couple of years. But still, it’s not Sci Fi.

Second I decided that instead of adopting the NaNo recommendation of turning off the spell checker, covering the backspace key and pumping words out (NaNo is about producing a first draft, not a readable first draft), I would actually attempt to not only hit the 1,667 word count target each day, but produce decent edited prose along the way.

This is turning out to be a more significant challenge. Not because the process it different, it’s actually closer to the way I would write outside of NaNo. But it’s tough to produce 1,667 edited words per day.

As I’m doing it I’m finding myself drawing parallels to the old statistic you’d have learnt years ago about programming. It goes, a programmer on average produces one hundred lines of code a day QA’d and delivered to a customer. Sure any decent programmer can type more than a hundred lines in probably forty five minutes if they’re in the zone. It’s getting it to a quality level the customer will accept that takes the time.

And that’s what NaNo’s like. It’s that forty five minutes of work that get’s you your hundred lines of code. And for discovering if you’re capable of writing a book it can’t be beat.

This time though my goal is to be able to give this book to my beta readers on December the first and not have them think I have the English skills of a nine year old.

So far I’m keeping up… just.
