I had the pleasure to work on a very large programme of work for the past two years and I witnessed how programme has changed its structure for handling bugs. Therefore I am sharing such result on this blog post.<\/p>\n
Very Large Agile project \u2013 year 1<\/b><\/p>\n
200 engineers (Devs and QAs):<\/p>\n
–\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 10 functional teams with 18 people each<\/p>\n
–\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 1 maintenance (bug killer) team with 20 people<\/p>\n
An average of 300 open bugs<\/p>\n
Weekly meetings for prioritizing bugs<\/p>\n
Bug Killer team is fully allocated and has the challenging goal of reducing the number of open bugs.<\/p>\n
Bug Killer team attrition rate was higher than the \u00a0functional teams.<\/p>\n
Despite of the best team effort, the average of open bugs never reduced.<\/p>\n
Very Large Agile project \u2013 year 2<\/b><\/p>\n
200 engineers (Devs and QAs):<\/p>\n
–\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 10 functional teams with 20 people each<\/p>\n
Month 1: 300 open bugs<\/p>\n
Month 2: 280 open bugs<\/p>\n
Month 3: 260 open bugs<\/p>\n
\u2026<\/p>\n
Month N: an average of 20 bugs<\/p>\n
Bugs are directed to the functional team closely related to the bug functional area.<\/p>\n
Test coverage and test effectiveness increased over time.<\/p>\n
Developers got closer to the operations team, and improved tools for chasing bugs.<\/p>\n
Should I have a separate team for handling bugs?<\/b><\/p>\n
No, not really. At least this was my experience. I have to confess that I started on year one and was very comfortable with the separate maintenance team model. I and other programme \u00a0leaders took the challenge of reducing the average bug numbers. \u00a0As an experiment, we tried to stay without a separate maintenance team for two months. We never went back to the old model.<\/p>\n
