Compared to the cloud model, the COTS and the acquisition model used here has both pros and cons. For instance, compared to the cloud model, the COTS has more of a cost advantage. Off the shelf products are usually prices higher but COTS is seen to offer for much more substantial savings. The COTS product unlike the cloud services could be limited time guarantees too, also the deployment of COTS solutions are much more faster compared to the cloud solutions. Usually compared to cloud solutions, small business owners might prefer the COTS. This is not only because of the budget friendly concerns but also because industries have unique needs and COTS helps to deliver them. However, COTS also has issues in that these products are customized to meet basic needs according to a sector of industries and hence might require frequent updates.
The use of a traditional methodology such as the SDLC will capture both functional and technical business requirements. Here the project team once again spends much time in the requirements gathering. The technical and functional requirements are all collected before coding for the same begins. Once coding starts however, the development team might be unprepared as they would be given a list of requirements but would have had no role to play in the initial requirements gathering phase. The lack of communication makes SDLC problematic. There are also issues of delays, costs and more (PwC, 2014). In this context it is much easier using a JAD as the technical team and the requirements team will both work together.
However, as research studies point out, it is necessary to understand that such a transition from the traditional model to SDLC might also not be all that easy. However, models such as the JAD would enable for better sustainability in improving project resource relationships and hence it must be considered.
