This section introduces the PPD Evaluation Wheel, used to visually evaluate different aspects of a PPD which contribute to its organizational effectiveness. The PPD Wheel addresses the 12 elements of the PPD Charter of Good Practice considered as essential contributors to an effective PPD process. For each of the 12 elements represented on the wheel, objectively verifiable indicators indexed on a scale from 1 to 10 have been identified. The average index between different indicators for a single process aspect gives the final score to be plotted on the wheel. Examples of the Evaluation Wheel usage from the Tanzania Mining PPD, Cambodia Government-Private Sector Forum (G-PSF), and the Benin Presidential Investment Council are presented, as well as an exercise for practice.
