GRPI:

GRPI – Goals, Roles, Processes, Interpersonal [Relationships] is a four-step project planning tool used in Six Sigma business methodology to help Green Belt and Black Belt team leaders ensure productivity, efficiency, and quality.

The four steps function as follows:

1) Goals – clearly defines the team's mission and establishes objectives that conform to the "SMART" approach (i.e., goals that are specific, measurable, attainable, relevant, and timely);

2) Roles – uses a "roles statement" to define clearly each team member's function and the interrelationships between individual and team roles, objectives, and processes;

3) Processes – identifies and defines processes inherent in and essential to the project (e.g., problem-solving, decision-making, etc.); and

4) Interpersonal – ensures open communication between team members, encourages creative and diverse contributions from all members, and discourages "groupthink."
