Predictive vs. Adaptive SDLC

Predictive vs. Adaptive SDLC

Q.1) Would you rather be part of a project that used predictive SDLC or adaptive SDLC? Explain your answer.

Various factors can influence the selected project development approach of an organization or project team A Systems development life cycle (SDLC) offer on the whole, a structure for supervising and managing systems development process. There are two approaches known for SDLC, which are known as Predictive approach and Adaptive approach.

Predictive SDLC is an approach that presumes that all the planning for the project can be outlined in advance and that the new information system can be produced or developed according to the plan. While Adaptive SDLC presumes that project require to be more bendable and acclimatize to altering needs as the project carries on (Warner, 2005).

The decision of selecting which approach to adopt depends upon the nature of the project. If project is known and requirements are well understood, Predictive SDLC must be followed as it presents a stable and particular improvement plan prearranged in the order to produce a predestined end result in a definite timeframe. While in the case of embryonic projects that face varying circumstances, Adaptive SDLC is suitable because Adaptive SDLC engross flouting a project into diminutive components over an undecided timeline to permit required litheness to direct the path of the project.

Q.2) Describe some pitfalls and some advantages of each approach.

Predictive SDLC - Advantages & Disadvantages

In Predictive SDLC, the project objectives are clearly defined and understood. This approach also has steady project requirements. Another advantage is that it allows measuring the progress of system. Also, the chances of technical risks are minimized in predictive SDLC approach. Although, the overall impact of predictive approach is advantageous but it does possess some possible weakness. One of which is that it is time consuming, as all the planning need to be outlined before starting project. It is also up to some extent traditional, which is because it is never carried out backward. It does not have enough room for iteration and it is not capable to respond changes.

Adaptive SDLC - Advantages & Disadvantages

In Adaptive SDLC, the most important advantage is its varying approach that allows addition of necessary functionality in the project accordingly at any instance of time. This approach is mainly focused on implementation rather than functionality. Due to its flexible timeline approach, additional functionality can be included later on. Speaking of weakness, this approach is highly customized that restricts the re-usability. Also, it needs to be applied in a different way for each application. The chances of technical risks are higher. Due to the on-going length of project, there is a chance of exceeding the budget in this approach.

Project Phase

Q.1) Which project phase is most important? Explain why.

In each project, there are certain activities connected with initiation of project, its planning, analysing, designing, implementation, and deployment. Each of these are called a phase. A brief overview is as follows:

Initiation - Involves activities for project identification, approval and ...
