Q1 What are the Limitations of waterfall model?Explain.
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
takesplace to determine if the projectisonthe right pa
Q2 Explainthe various phasesof RAD model.
Answer: RAD model is Rapid Application Development model. It is a type ofincremental model. In RAD
model the components or functions are developed in parallel as if they were mini projects. The
developmentsare time boxed,deliveredandthen

2. Q.3 Explainthe various stepsinvolvedinestablishinga reliabilityspecificationandstatistical testing.
Answer: Design for Reliability (DFR) is not a new concept, but it has begun to receive a great deal of
attentionin recent years. What is DFR? What are the ingredients for designingfor reliability, and what is
involved in implementing DFR? Should DFR be part of a Design for Six Sigma (DFSS) program, and is DFR
the same as DFSS? In this article, we will try to answer these questions and, at the same time, we will
propose a general DFR process that can be adopted and deployed with a few modifications across
differentindustriesinawaythat will fitwell into
Q4 Briefly explain the unspoken assumptions that have played an important role in the history of
software development.
Answer: Since the beginning of software development which was somewhere in the late 1940s, various
software types have gone through many stages of evolution. It has evolved steadily throughout the ages
and applicationsof varioussoftwaretypeshave reachedheightsthatwere notthoughtto be possible.
One important factor that boosted the development of software throughout the ages was that new and
improved computers were coming out into the market at an unprecedented rate. The development of
computerhardware technologydemanded
Q5 Explainthe significance ofSoftware Refactoring.
Answer: Refactoring is the process of changing a software system in such a way that it does not alter
the external behaviorof the code yet improvesits internal structure.
Code refactoring is the process of restructuring existing computer code – changing the factoring –
without changing its external behavior. Refactoring improves nonfunctional attributes of the software.
Advantages include improved code readability and reduced complexity; these can improve source code
maintainability and create a more expressive internal architecture or object model to improve
extensibility.Typically,refactoringappliesaseriesof
Q.6 Discussthe various test designmethodsusedin real time software testing.
Answer: Real-time testing involves testing a system when it is running at its normal operating speed to
ensure that operations are completed within their deadlines. When is comes to testing real time
