One of the key ingredients of DSDM is ‘ Timeboxing’ which ensures delivery in time. This is another major advantage of DSDM. Moreover in case of DSDM, since representatives of users are likely to provide the training, the users would be trained in a better way. Users are involved in the process of using DSDM in a formalized way (DSDM Consortium, 1998). Implementation of DSDM takes place in a smooth way as there is excellent cooperation among all the parties in the process of development. All the stakeholders are incorporated into the development process.
Another important advantage of DSDM is that there are fixed cost and time of the entire project. Moreover, DSDM is flexible enough as far as the evolution of requirement is concerned. Like any other model, DSDM also has several disadvantages which are mentioned below. One of the major disadvantages of DSDM is that the requirements are needed to be progressively developed. Furthermore, DSDM is mainly focused on ‘ Rapid Application Development’ practices as a result of this code robustness might get decreased. There is too much requirement of user involvement in DSDM.
The team that is involved in the development of DSDM needs to be skilled in both technical and business area. These are the two other main disadvantages of DSDM. DSDM was initiated in 1994 and since then it has enjoyed several successes. Over time it has become more and more popular in and outside Europe. Today more number of managers is relying on DSDM for solving their business problems. But there are few organizations which have used DSDM. Dublin based Online Computer Library Centre (OCLC) is among those few organizations.
It was involved in developing software for libraries, academic institutions and museums. In the year 1998, the company was facing problems regarding its software delivery. Prior to the use of DSDM, projects in OCLC were used to take 18-24 months in order to deliver the final product and by the time products were ready for delivery, they were likely to become obsolete in the market.
