Regularly releasing potentially shippable softwarePosted: February 17, 2010
Brian Marick wrote a couple of years ago that “Teams that don’t produce potentially shippable software at the end of each iteration are likely in trouble.”
With more and more teams using a kanban approach to developing software, it would seem that producing potentially shippable software on a regular basis would be more common. But is it? Does your team produce potentially shippable software at the end of each iteration? Why or why not? What can we do to make it the case?
Kanban requires a rigorous dedication to building software. If your “agile circumstances” are less than ideal — and really, how often do you have an ideal situation? — such as an unengaged customer, nebulous deliverables or uncertain deadlines, you need to be all the more rigorous. Build in practices that keep the team honest, like a regular demo (even if the customer doesn’t attend). I’ve seen too many teams burn themselves by waiting until the last week of the project to create a CI build server or see if they could cut a release. If the team releases potentially shippable software starting after the first week of the project and continuing regularly, they’ll save themselves a lot of headaches and reduce the risk of a nightmare end of the project. And they’ll focus on giving their customer something of value each week, instead of what amounts to a bunch of work in progress at the end of the project.
