The MCPA® is a powerful research based instrument, with an online questionnaire called the MCPQ® that records a candidate's responses to a series of phrase cards in 30-45 minutes. The data collected supports a structured interview, in which a counsellor will establish the candidate's current level of capability and potential for this to grow over time. MCPA is based on the Bioss theory of Levels of Work that identifies 7 levels of organisational complexity, ranging from the direct, through the organisational to the strategic. The MCPA is an exceptionally powerful and useful instrument because it directly addresses two of the most important issues in executive development - current capability and potential. It is also one of the few methodologies to have been the subject of a full independent validation at national research institute level.
