1.  Task Name:  Perform Application Development

2.  Purpose:  Rapid Application Development (RAD) encompasses requirements definition, design, construction or development, and unit testing.  Each of these activities is performed in repeated cycles with new and changed requirements moving iteratively through each of the four activities.  The leader for the Development Integrated Product Team (IPT) controls the cyclical flows, ensures continuous and productive contact with the customer to extract requirements, and reports any conditions which adversely impact cost and schedule to the Program Manager/Functional Project Officer and Technical Project Officer.  The design documentation and the formal development cycle review are performed after the database and software design portion of this task.  The customer participation is continuous, starting with the communication and recording of requirements, assisting with the design of user interfaces, and immediately reviewing test results. The review of test results may reveal design flaws or the need for changed requirements which will cause the initiation of another cycle.  The Development IPT employs the tools selected and installed to support RAD.  The product of RAD is the tested software ready for functional integration/acceptance testing with information provided for all necessary documentation and approvals as a by-product.  Software quality assurance is attained through daily review of products and results and day-to-day communications among members of the IPT under the guidance of a software quality assurance analyst.
