Deconstruction of a Failure

MozReview started out as essentially a skunkworks project with only a few people: an engineering manager to oversee the project, a couple coders (one full time, one contract), and a senior-staff-level (or thereabouts) engineer who acted as a sort of customer/consultant. I should have paused the project and done some serious customer research and evangelism (since the team honestly believed the new ways of working that MozReview represented would have a positive impact on productivity, at least over time). This had many ramifications: too much to learn at once, a confusion as to what parts of the new system were responsible for what, and too much to work on at the same time for the MozReview developers.
