My adventures in software development.
I have been an Agilist from the beginning of 2007. I am a Partner/Entrepreneur/Lead Consultant at Omenia. And now my friends, I want to share my observations.
The release date is approaching and some important features are still missing. It might be that we are losing a customer because of that. There are basically two paths to take. First one is to start cut corners, do some hacking, maybe not test that thoroughly etc. In other words we take technical debt to try to reach our goal. For the short term point of view, this sounds attractive.
Your nightly build is red. There are some test cases failing and you know that this should be the moment when you need to stop and investigate. Your Product Owner runs in the team room and start to rant about features which must be in before the release at the end of the week. He is questioning are those faults so bad that we really need to consume time to fix them, because we have promised some cool stuff to our customer.
What to do? Every time we have failing test case(s) in our build(s) it means that our location is unknown, failing test case says that behavior of our product is not what we have expected it to be and before those case(s) are green again, everything what you create are just hypothesis.
Abnormal situation is work need to be done, and it's work that does not get any better with age, actually quite the opposite. It's work which generates more work. On the other hand, if we use stop the belt and fix the problem immediately it causes idling to the rest of system and the bigger the system is, the bigger the effect of idling is. So what do? I think that abnormality should always be removed as soon as it is noticed. We should always have the best understanding where we are and get back on the map quickly.
