The Software Process and Measurement Cast 774 is a re-release of SPaMCAST 436. We are on our annual holiday and will be back with new programs on October 22nd. For the next four weeks, we will feature shows from our archives. Today SPaMCAST 436 - Incrementalism, UAT and Agile, and Systems Thinking was released originally on April 3, 2017. I hope you will enjoy today's show! The original introduction - The Software Process and Measurement Cast 436 features our essay titled, Change Fatigue, Tunnel Vision, and Watts Humphrey, in which we answer the question of whether the state and culture of the organization or team, can have a large impact on whether a Big Bang approach or an incremental approach makes sense to change. Our second column is from Jeremy Berriault. Jeremy discusses user acceptance testing and Agile. There are lots of different ways to accomplish user acceptance testing in an Agile environment. The only wrong way is not to do UAT in Agile. Jeremy can be found at https://www.berriaultandassociates.com/ Jon M Quigley brings his column, The Alpha and Omega of Product Development, to the Cast. This week Jon puts all the pieces together and discusses systems thinking. One of the places you can find Jon is at Value Transformation LLC.
