Every organization develops a design as a way they operate in order to execute its goals. Among different types of organizational structures, this paper will focus on both flat and tall organization structures. The main intention is to find out the effect that these company structures have on the employee’s commitment, creativity, and motivation. A considerable portion of the effort devoted to this research will be spent on organization's structural design factors such as specialization of work, standardization of work, span of control, departmentalization, centralization, and decentralization and their effect on employee-related factors like motivation, creativity and commitment. The study relies on a mixed-method with an online survey conducted among 90 employees of 2 Swedish IT companies. This paper concludes a clear trend in favor of the flat organizational structure as it encourages employees to be more creative and motivated. Regarding their commitment, the findings show that employees of both organizations are committed to working at the same level.
