What are the major advantages/disadvantages of the SDLC?
Iterative SDLC Model
|It is easier to control the risks as high-risk tasks are completed first||The process is difficult to manage|
|Problems and risks defined within one iteration can be prevented in the next sprints||The risks may not be completely determined even at the final stage of the project|
What are the advantages of unified process?
Advantages of Rational Unified Process
Emphasizes the need (and proper implementation of) accurate documentation. Diffuses potential integration headaches by forcing integration to occur throughout development, specifically within the construction phase where all other coding and development is taking place.
What are the advantages of starting early testing in SDLC?
Software testing should start early in the Software Development Life Cycle. This helps to capture and eliminate defects in the early stages of SDLC i.e requirement gathering and design phases. An early start to testing helps to reduce the number of defects and ultimately the rework cost in the end.
What are the advantages and disadvantages of waterfall model?
Advantages and Disadvantages of Waterfall-Model
|Before the next phase of development, each phase must be completed||Error can be fixed only during the phase|
|Suited for smaller projects where requirements are well defined||It is not desirable for complex project where requirement changes frequently|

When should we stop testing?
Many modern software applications are so complex and run in such an Interdependent environment, that complete testing can never be done. 2) Stop the Testing when the test cases have been completed with some prescribed pass percentage. 3) Stop the Testing when the testing budget comes to its end.
Is SDLC and waterfall the same?
Agile and Waterfall are both Software Development Lifecycle (SDLC) methodologies that have been widely adopted in the IT industry. The Waterfall framework was designed to enable a structured and deliberate process for developing high quality information systems within project scope.
Why is waterfall model not good?
Waterfall Model – Disadvantages
High amounts of risk and uncertainty. Not a good model for complex and object-oriented projects. … Not suitable for the projects where requirements are at a moderate to high risk of changing. So, risk and uncertainty is high with this process model.
Why is Waterfall better than agile?
If the project timeline is fixed and can not be moved, Waterfall will offer a more predictable outcome. If you need to get the project delivered in a short amount of time, Agile is the appropriate choice here where action and getting things built is more important than documentation and process.
