If you have worked in IT for a while you see the same things happen over and over again. When you have worked in IT for a few more years you start questioning the things you see and wondering if there is another way. Given a few more years you’ll be the one shaking things up so the old norms are consigned to the dustbin of history.

The topic I’m touching on today is working practices for software developers or more precisely it is a challenge to the long hour’s culture often seen in software development.

There was a time (and it probably still happens today) where you simply didn’t leave work until after the boss did. They leave at 8pm so you’ll be leaving at 10 past. People would work 10, 12, 14 hour days so they looked like the important one, the busy one, the one that could be depended on. How many times have you heard people recount the 50 or 60 hour weeks they have worked and hold it aloft as a badge of honour.

Using these old terms, I might be considered a boss. Well I’m usually the oldest on a team but I certainly don’t consider myself a boss. Do I expect people to leave after I do? – no I don’t! Instead I judge people on results and how they interact with their team mates. Not on how much stamina they have.

I have likened the mental effort of software development to doing an exam. You’re doing complex mental puzzles for many hours each day. Having done this myself, I know that if I work flat out for 6 – 7 hours I’m mentally spent. After that I’m in neutral. I might be trying but nothing much is happening. Many studies have demonstrated that most people’s mental capacities are similar. If you tell me that you have been doing 12 or more hours a day I question what you actually have been doing in that time or whether that time would have been better spent recharging for the next day.

Lean and Agile tell us to use prioritisation and work in progress limits to set a predictable and sustainable pace. This means that the 6 – 7 hours mental capacity each developer spends each day is always on the most important thing. There is no stress and no pressure. You are always working on the most important thing. I’m not saying you only work 6 – 7 hours. Instead you are free to use the time outside of that for what you want, whether that is a side project, training or otherwise keeping yourself sharp.

Unfortunately, development teams don’t work in a bubble. There are often arbitrary deadlines which need to be dealt with. Before I move on to that, it is worth digressing for paragraph to consider why Agile teams find themselves with deadlines.

Too familiar?

When these deadlines come up it is important to recognise where they are coming from. In my experience, it is always someone outside the team, not working in your sustainable pace each day. It might be a sales person who has committed to a customer that feature X will be ready by Y. It might be an external supplier who is expected to integrate with your software by a given date. The commonality is that they don’t know what the pace of the team is and they have plucked a date from thin air without any further context or understanding. They have made a commitment on your team’s behalf.

So, the team has to knuckle down and get on with it. The first thing to do is reprioritise. Focusing on the new commitment might still be achievable if all other things in the backlog are delayed. If not than the team should agree between themselves what the new working arrangement should be. It is a team decision and they should resist the urge to be dictated to from outside. This can be very emotionally charged as the external stakeholder may see the team not caring. What is really happening is the stakeholder has put their neck on the line and now they what everyone else to pull out all the stops to save them.

Everyone should recognise that as hours increase quality suffers. Notice I didn’t say “may suffer”. Quality will go down. Mistakes will be made. One strategy to minimise this is to ensure each team member has some opportunity to rest and recover. Not only is it important for their own mental state, a fresh pair of eyes are more likely to identify mistakes early.

Doing this however it a symptom of a wider problem. Ideally resolving it might be in your control but more often than not, it is cultural and is much harder to change.

Regardless, my mind is set. You can keep your evenings fuelled by pizzas and your days off in lieu for weekend work. All I want is a sustainable pace.
