management commonly uses the experience curve in estimating the production costs of (1) a product never before made with the present techniques and processes or (2) current products produced by newly introduced techniques of processes. the concept was first applied in the air frame industry and can be applied in the service industry as well. for example, a cleaning company can reduce its costs per employee by having its workers use the same equipment and techniques to clean many adjacent offices in one office building rather than just cleaning a few offices in multiple building. although many firms have used experience curves extensively, an unquestioning acceptance of the industry norm (such as 80% for the air frame industry or 70% for integrated circuits) is very risky. the experience curve of the industry as a whole might not hole true for a particular company for a variety of reason
