Agile Contextual Development Model with Open Source Software for Critical Web Site

Abstract

Many development models were derived in a situation which is different with the place where the system will be used. For example, many development methods were created in laboratorium setting which is very different with reality. The used of software development method without considering the local constraint and preference may yield an unsuccesful result. However, effort to satistfy local needs sometime cannot be achieved due to the license restriction. The web sites system of the President of Republic Indonesia is developed by small number of team in short time with limited budget. However, the developed system can satisfy the requirements. For the development we developed a novel method which employs the Why Because Analysis by using Lightweight Why Becuase Graph. In this development model we start by using example based requirement elicitation. It also demonstrates the flexibility of FOSS to provide solutions that are difficult to be fulfilled by proprietary solution. In this project, FOSS shows strong point in some area such as virtualization, security, and reliability. FOSS always is capable to fulfill the additional requirement during the operation of system. In other word, FOSS is possible to provide a sustainable solution.
