[ Finisher ]
There should be a role called “project finisher”. This would be the person or team that comes in like a cleaning crew, once the project is in its last stages. By then, the project manager is either exhausted, or thinking about the next job (or more likely, both). The project team is also exhausted, and thinking about the next job.
It’s a different skill to gather up the project data, sort through the material data records, capture lessons learnt and write up the project case study.
Everyone knows it’s important to do all those tasks. It rarely gets done well.
