Establish win-win agreements

In the Win-Win agreement, the following five elements are made very explicit;

1. Desired results are recognized;
2. Guidelines are delineated;
3. Resources are identified;
4. Accountability is set up; and
5. Consequences are specified.

Steven R Covey

Desired results (not methods) identify what is to be done and when.
Guidelines specify the parameters (principles, policies, etc) within which results are to be accomplished.
Resources identify the human, financial, technical, or organizational support available to help accomplish the results.
Accountability sets up the stands of performance and the time of evaluation.
Consequences specify-good and bad, natural and logical-what does and will happen as a result of the evaluation.
