Q. Explain Different Phases of spiral model?
1) Planning: In this phase the objectives alternatives as well as constraints of the project are determined or documented. The objectives as well as other specifications are fixed so as to decide which strategies or approaches to track during the project life cycle.
2) Risk analysis: In this phase every possible and available alternatives which are able to help in developing a cost effectual project are analyzed and strategies are decided to use them. This phase has been further particularly in order to identify as well as resolve all the possible risk in the project development.
3) Development: In this phase the authentic development of the project is carried out. The productivity of this phase is passed by all the phases iteratively in order to acquire improvements in the same.
4) Assessment: In this phase developed product is passing on to the customer in order to obtain customer comments as well as suggestions which can help in identifying as well as resolving potential problems or errors in the software development.

Q. Management Issues in software development? Management Issues:-Project managers typically write the risk management plan and most people don't wish to air their weaknesses in
The aim of regression testing is to test that the fixes have not formed any other problems elsewhere. The aim is to ensure the software has remained intact. A baseline set of data
What is cyclomatic complexity? Cyclomatic complexity is given by McCabe. The general formula to compute cyclomatic complexity is M=V (G)=E - N + 2P Where E-Number of e
The process of evaluating a program based on implementation of that program. Dynamic analysis approaches rely on implementing a piece of software with selected test data.
Recovery/error testing is testing how well a system recovers from crashes, hardware failures, or other catastrophic problems.
How can we re-engineering of any product One additional difficulty in adopting this approach is large investment which exists in software system maintenance. It requires additi
Abstraction :- Abstraction allows one to concentrate on a problem at some level of generalization without regard to irrelevant low level details; use of abstraction also allows one
