I. Background of the case
In the case, there are (2) two different lifecycle models in different scenarios, a) the prototyping and b) the spiral model. Giga-Safe wants to upgrade the current version of the software, fix bugs, and make minor changes in the current user interface (GUI). They are to do this in 6 weeks. In view with this, the project manager insists on using prototyping because he believes that it is the fastest approach. But on the course of these changes, it caused delay on the completion of the upgrade by 6 weeks. The project team released the version with bug fixes and corrections on the GUI.
On the other hand, Square Tech is developing a new product called “Cube-It.” It is a scientific graphic package. The plan is to minimize risk and the implementation time given is 1 year. The spiral model was used. Planning was carefully done. They started by analyzing risks on alternatives and the consequences which may result after which. After alternative selection through customer evaluation process, the team analyzes the risks of the chosen alternative and comes up with new alternatives. This process repeats until final design’s achieved. On the implementation, errors were minimized. System testing was delivered after 11 months and quality was excellent. Cube-It 1.0 was released on time.
II. Statement of the Problem
What is the most effective lifecycle model?
III. SWOT Analysis
|Faster approach to software development. |Mainly used to optimize the system's architecture before design | | |decisions are made by coders that would cause problems. | |The software designer and implementer can get valuable feedback from |Combines the features of the prototyping model and the...
