I find it amazing that those looking from the outside of a project can sometimes seem so knowledgable especially when things aren’t going so well. If only the project team had access to that knowledge along the way 🙂
Ok I am saying that tongue in cheek but when things don’t go quite right on projects others are quick to point out what should have been done. This is where comprehensive check lists are key in reviewing projects on a regular basis. One of my ideas is to set up regular team reviews of those lists so we never forget some key things on a project
Any ideas on good check lists? More mature organizations have a Governance group or a finance toll gate – all seem like more work but when truly run effectively can save you work and lessen the stress of go live
Project Delivery and Team Building 
It’s amazing how project participants can have selective memory lapses even when their decisions are documented in meeting notes. Regular review of the assumptions goals and changes to either need to be included in your project review. Usually less than 5 minutes every other week to keep everyone on the same page is a very small price to pay.
