Kerry Buckley What’s the simplest thing that could possibly go wrong?

I see Adewale Oshineye has posted some excellent photos from XP Day. Fortunately all you get to see of me is the back of my head (and hard as it may be to believe for those that know me, I’m not deliberately hiding my face in the second one!)

Here are some notes from the recent (excellent) XP Day conference. This is based on my internal BT write-up, with a few company-specific bits removed.

An excellent post on Kill the Meeting, pointing out the insane amount of bureaucracy you end up with when writing code is treated as an unskilled production line activity.

On one recent project, the software development managers insisted on a 5-page requirements definition document, two management reviews of that document, a functional specification with four contributors, a peer review and a management review of that document, a detailed design document, a management review and sign-off of that document, and a test plan before development could begin on the code.

The code in question? Five lines of SQL.

Yes, a 2-hour project took over a month.

Some of that sounds horribly familiar from past projects. What’s the betting that the people writing and reviewing the documents could have written the code themselves in a fraction of the time they spend ‘saving money’ by contracting the work out, if only writing code wasn’t treated as a menial task to be discarded on promotion?

One issue with the conclusion though:

Unfortunately for me, I don’t think this is a process I can change here. It turns out that outsourcing development to India is so much cheaper that even if it takes four times as long, it’s still a net savings.

Even pretending that the offshore developers were free, that only holds true if the time spent in-house doing all the design, documentation and reviews was no more than eight hours, which sounds unlikely. To my mind, outsourcing software development to release your own people for ‘higher value’ work only costs in if you outsource the lot, from requirements to delivery. Otherwise you end up employing the same number of people just to keep the cheap developers on the right track.

A colleague recently posted (on an internal wiki, so unfortunately I can’t link to it) about the problem of people thinking that common agile “tools” such as whiteboards, index cards, freehand burndown graphs etc are a bit “Blue Peter,” and therefore not professional. He made a good suggestion, which was that you provide teams that are new to agile with official branded materials (story cards, pre-printed blank burndown charts and so on). They will accept these more readily, and will then embrace the underlying ideas and start using any old flipchart or whiteboard.

Here’s another argument for simplicity – admittedly from the world of TV fiction – which I’d put to people who think low-tech solutions are somehow not fit for purpose.
