Requirements management for the incremental development model

Requirements management is a crucial process in software engineering. Nowadays, information technology is applied in many fields of society. The change in requirements becomes an inevitable fact. However, good quality means conformance to customer requirements. A good and suitable software engineering model and efficient requirements management is required. The paper discusses the method of requirements management for the incremental development model, the goal of the management, the structure of data collection, and the metrics of the capability measurement.
