Determine Organizational Structure First
The bottom-up approach in my view, should be considered only after determining whether the structure within which it must be implemented, into a classification called "stars". The company is in a start-up phase, sustainability, revitalization, turnaround, closure / withdrawal.. These different situations determine the level of responsiveness and contribution of employees. Clearly, consult and decide is a viable solution to the extent that employees adhere sufficiently to the culture and the trajectory of the company (the living environment, compensation system, motivation and reward, career prospects, and especially recognition as a creator of value).
