Companies always follow certain management models according to which objectives are defined, efforts motivated, activities coordinated and resources allocated. The first step for any commercial organization is to choose a definite management process or model towards achieving its objective and conducting its day-to-day functions. The selection of management model is a companyâ€™s own prerogative and dependent on several internal and external factors. It is quite possible that two companies in the same industry follow separate management models. According to Birkinshaw, any management process has four dimensions, namely, objectives, effort, coordination, and making decisions.
