And the final point, which I’ve seen lots of teams forget, is to communicate your decisions. You may have invented the greatest modelling idea since the sticky note, but if only a few people in your team know about it, then you probably made things worse.
So tell everyone.
If you can get your team round a table for a 1/2 hour daily stand-up, then this won’t be a problem. But if your team are scattered across the world in multiple time-zones, then it’s going to be harder, so you’re going to have to try that much harder when communicating. And this will take time and cost money, so someone needs to schedule and pay for that. And that person will expect to see the benefit of spending the time and the money in a more re-useful* *(sic), more valuable model.
Your communications should have lots of examples – how to use it, how not to use it – so that in 3 years time when someone tries to re-use your model, they have every chance of understanding what you created. And put those examples into the model, so they don’t get lost.
Because that’s what all this is about. Making models more useful.
