One of the most important components in organizations is the management process, and unfortunately, there are almost no existing mechanisms that can be used to evaluate their performance. Management processes can connect all individual functions into an integrated organic network, which can then move toward the objective of the organization. The current researches mainly use interviews and questionnaires to qualitatively explore the suitability of the processes, nevertheless, their conclusions cannot be effective over a long period of time, nor be universally applicable. This study intends to develop a model that can quantitatively measure the performance of the management processes in manufacturing and service industries, and evaluate the maturity level of the process. Based on the model, enterprises are equipped to improve performances that are interrelated with these processes, and therefore, internal operational efficiency and effectiveness can largely be improved, leading to high competitiveness. .
