Normally a few weeks. It is designed to meet customer satisfaction as well as improve suppleness. Each progressive stage incorporates more features as per the needs of the client. This method does not require detailed planning from the start but there has to be constant communication with the customer to ascertain the specifications. At the end of each stage, the product is tested to prevent a failure in the future.
