Since "Lessons Learned" meetings are typically chaired by the people who ran the project, would you ever see comments about ...

a) Incompetent managers such as those who 'manage by the spreadsheet' (i.e. whose sole contribution is to harass people who are 'behind schedule') and otherwise do nothing to deal with problems that are getting in the way of things?

b) Unrealistic deadlines that lead to people focusing on 'good-enough' results that lack robustness?

c) 'Outsourcing' or 'offshoring' decisions made, possibly, by another part of the organization (such as Finance) who are nicely shielded from the results of their decisions,  that transfer work to some distant group under the guise of 'saving money' but which reduce the ability of the project to oversee quality of results?
