According to the Interim Management Association, “Interim Management is the rapid provision of senior executives to manage change or transition”. In simpler terms, an interim manager is a highly experienced and specialized executive whom you can employ for a short time to solve a specific business problem. He or she is a master project manager who will not only give you advice, but also implement your solution.
 
In short, an interim manager meets your specialized needs, is more motivated to look out for your best interests, is actively involved from start to finish on achieving solutions, works with your own people and reports directly to you. He or she develops the strategies and then implements them.
