Question No: 25 ( M a r k s: 5 )
Define different models of SDLC?
Answer:
Models of System development life cycle:
Waterfall model / Classic lifecycle/ Linear Sequential Model:
The waterfall model is a software development model (a process for the creation of software) in which development is seen as flowing steadily downwards (like a waterfall) through the various phases.
Incremental Models:
In incremental models, software is built not written. Software is constructed step by step in the same way a building is constructed. The products is designed, implemented, integrated and tested as a series of incremental builds, where a build consists of code pieces from various modules interacting together to provide a specific functional capability and testable as a whole.
Iterative Models:
In these models customer feedback is taken at each phase and project is modified accordingly – if need be. Prototypes are used in these models.
Question No: 26 ( M a r k s: 5 )
Differentiate between Empire Building and Garbage Can Model.
Answer :
Garbage Can Model:
This model states that organizations are not rational. Decisions made are largely on accidental basis. Hence wrong solutions may be applied to wrong problems in an organization and critical mistakes may occur.
Information systems should be designed to support and assist in relevant decision making, instead of making unrelated and wrong decisions.
Empire Building:
Empire building is a business term that refers to a common problem in larger organizations, in which managers attempt to gather more administrative and financial power. Power can only be shared in an organization with key employees in terms of their responsibilities & functions. Such employees are the key players in the decision making process. Hence decisions taken in an organization are a result of collective efforts of the leaders involved. This model is also termed as Political Model.
