Abstract:
Software development today is a complex area, in which new problems and challenges constantly arise, competition is rather high, and it is difficult to maintain high position on the market. This paper aims to introduce and develop a validated prototype-based RAD model using the evolutionary approach with the purpose of minimizing the risk of changes in software engineering and to have a product that meets its expectations in terms of functionality, cost, quality, and delivery schedule. Rapid application development (RAD) is created to present a higher level of responsibility that includes both a business unit requirement capturing and testing. Contact and interview case study participants approach are taken in deriving and validating the proposed model. Then, survey instruments undergo for testing and evaluation process for measuring the effectiveness and efficiency of the proposed model. The case study results showed reduction in the project risk to be behind of the delivery schedule, cost of software development, improve the quality of the system and deliver software that actually meets the needs of users.
