Retrospectives are a very important aspect of agile development and continuous improvement. Doing retrospectives at different levels is imperative to successful projects and even entire programs. Sometimes, you need to have a retrospective with a larger audience participation to improve across multiple projects or at a program level. In Design Studio and Senior Design here at the University of Nebraska-Lincoln, we manage 40 plus projects with more than 250 student team members combined. We want to continually improve our processes to make these programs the best they can be. Therefore, we regularly conduct retrospectives with 100+ participants. These large-scale retrospectives can be challenging to manage, but we have determined easy ways to keep everyone engaged and participating and most importantly, getting guidance and suggestions on realistic improvements to be made to the programs. We will show our various methods for conducting these large-scale retrospectives and give insights on successful and unsuccessful procedures.
