Q1. Write short noteson waterfall model.List its advantages and disadvantages.
Answer:- The Waterfall Model was first Process Model to be introduced. It is also referred to as a linear-
sequential life cycle model. It is very simple to understand and use. In a waterfall model, each phase
must be completed fully before the next phase can begin. This type of model is basically used for the for
the project which is small and there are no uncertain requirements.At the end of each phase, a review
takes place to determine if the project is on the right path and whether or not to continue or discard the
project. In this model the testing starts only after the development is complete. In waterfall model
phasesdo not overlap.

Q2. Differentiate predictive SDLCand adaptive SDLC
Answer:- Software development is a relatively new discipline which moved into the mainstream in the
early eighties, though the origins of software development can be traced back to World War II. With the
explosive growth of software in the early eighties, the software industry suffered a so-called software
crisis, which really reflected the immaturity of software development as a discipline. Most development

2. Q3. Describe the XP values- feedbackand courage.
Answer:- Extreme Programming (XP) is a software engineering methodology, the most prominent of
several agile software development methodologies. Like other agile methodologies, Extreme
Programming differs from traditional methodologies primarily in placing a higher value on adaptability
than on predictability. Proponents of XP regard ongoing changes to requirements as an often natural
and often inescapable aspect of software development projects; they believe that being able to adapt to
changing requirements at any point during the project life is a more realistic and better approach than
attemptingtodefine all requirementsatthe
Q.4 brieflyexplainsabouttracker and coach inXP.
Answer:- Agile Methods are becoming more popular since Extreme Programming was introduced by
Kent Beck in 1999. Agile Methods propose a new way of looking into software development, focusing
the attention on the interactions between people collaborating to achieve high productivity, delivering
high-quality software. The approach to obtain these results is based on a set of simple practices that
provide enough feedback to enable the team to know where they are and to find the best way to move
towardsan environmentof continuousimprovement.
One of the practices that enable the creation of such environment is called tracking. Kent Beck describes

Q.6 List and explainany five basic principlesofDSDM.
Answer: - Principles: - There are eight principles underpinning DSDM Atern. These principles direct the

1. Focuson the businessneed
The main criteria for acceptance of a "deliverable" is delivering a system that addresses the current
business needs. Delivering a perfect system which addresses all possible business needs is less
importantthanfocusingoncritical functionalities.
