Mutations and promotions

Organizations need to make choices on human capital on a regular basis. These are often complex management issues. Who has the necessary skills to replace an employee who retires or leaves the company? Maybe we need to modify the expectations of the job?  How do we ensure that the right employee is put in the job without pulling him inefficiently out of a job where he has proved to be successful?  How do we ensure a lasting motivation of existing employee(s)? The answer to this questions are complex. Only a thorough and professional decision can ensure a sustainable solution for the future.
