The main similarity between GECON and ABM is related with searching improvement of internal process, by the managing activities. About the differences, it is possible to observe that the ABM takes more care with the supply chain, while GECON is worried about calculating the economic profit, by defining several criterions of valuation of the economic, accountant and financial aspects, which support its management model.
