Designing A Large E Commerce Transformation Project

As I grew from a developer to technology lead to Project Manager, I have started to appreciate each methodology for its own strength and weakness. Below are the strength and weakness of individual methodology that I concur based on experience. When we implemented a large E-commerce transformation project that requires the application to be ported from one platform to another, we followed waterfall methodology. Since it was replication of the same functionality, the requirements were very well documented and available, hence waterfall fit into the project execution. We also had a must meet timeline that is non-negotiable with well-defined team structure. Based on the experience following are the strength and weakness of waterfall†¦show more content†¦I haven’t used JAD for development or system/functional testing due to it’s known weakness. JAD works very well when we require SME’s across multiple domains whose availability is limited and hard-pressed. With the involvement of senior management in the JAD process, it provides purpose and commitment to project timelines. Following are the strength and weakness of JAD. Strength †¢ JAD decreases time and costs associated with requirements elicitation process. During 2-4 weeks information not only is collected, but requirements, agreed upon by various system users, are identified. Experience with JAD allows companies to customize their systems analysis process into even more dynamic methodology for mission-critical work. †¢ JAD sessions help bring experts together giving them a chance to share their views, understand views of others, and develop the sense of project ownership. †¢ The methods of JAD implementation are well-known, and can easily be applied by any organization. †¢ Easy integration of Computer-aided software engineering (CASE) tools into JAD workshops improves session productivity and provides systems analysts with discussed and ready to use models. Weakness †¢ Without multifaceted preparation for a JAD session, professionals valuable time can be easily wasted. If JAD session organizers do not study the elements of the system being evaluated, an incorrect
