An Extended Adaptive Process Model for Agile Software Development Methodology

Agile methodologies focus on the agility for the development of software. Among various agile methods, eXtreme Programming (XP) is the most adopted agile method. XP has been used for the development of other agile methods, for example, "adaptive software development process model" (ASDPM), which is the modified approach of XP. ASDPM was proposed to support the following activities: "(a) communication and planning, (b) analysis, (c) design and development, and (d) testing". Based on our literature review of ASDPM, we identify that ASDPM does not support the following: (i) how to identify the different types of agile team members who will participate during the communication and planning phase?; and (ii) how to deliver the most important requirements of the software during analysis phase?. Therefore, in order to address this issue and to strengthen the analysis phase of agile process models, in this paper we propose an extended adaptive process model (APM) for agile software development methodology. This method includes the following steps: (1) identification of agile team members, (2) communication and planning, (3) analysis includes the computation of function point of each requirement; and the selection and prioritization of the requirements, (4) design and development, (5) testing. Finally, the utilization of the proposed method is demonstrated with the help of Institute Examination System, as a case study.
