With high employee turnover how do you handle incorporating past Lessons Learned so team does not make same mistakes?
I have 8 scrum teams. We use lots of consultants. I see us making the same mistakes that are already in our lessons learned. How do I drive these lessons across all the teams, and to new team members?
Consider embedding lessons learned into the Definition of Done at an organizational level, and creating a sense of urgency for change to happen. Change will have to be more important than the day job.
First order of business - be sure that YOU are not a part of that turnover.
Team agreements might help. The team agrees to operate in some specific manners. Doesn't matter if the team makeup has changed. Especially if you are using a lot of consultants. Consultants work according to the rules of the organization that are paying their bills. So have some basic rules that they need to follow. Such as @Ian's suggestion of incorporating some of them into the Definition of Done.
