The solution was as simple as forced transparency. It was a social/culture problem, not a technology problem. It was not about the tools. Almost any tool can be made to solve for this problem. It was about the people.
To solve for this:
1. You need to have explicit support from the senior executives, almost like a get out of jail free card that allows you to skip entire segments of chain of command. Without this you are dead on arrival.
2. You need goals and a plan.
3. You have to coach the impacted teams. Some teams will get this immediately require only periodic validation, a few minutes a month. Some teams will require constant training and hand holding.
If you think you can solve for this with a software tool then just give up now, because you are only spinning your wheels. More than 80% of the total effort requires talking to people.
