The correct answer is organizational restructuring
Organizational Restructuring aims to organize the company to offer a quality structure to its customers, but with a different focus from the Process Redesign. While the redesign involves all the company's processes, the restructuring addresses the organization of the organization's employees, that is, with the positions and hierarchies.
An Organizational Restructuring project goes through a thorough analysis of all the current positions in the company, identifying which are the existing positions, which need to be changed and eventually, which do not exist, but which need to be created. A document describing in detail the functions, responsibilities, degree of hierarchy, subordinates and title of positions, are normally part of this work as a way of making the changes and making clear the activities and responsibilities of each employee.
