This set of Software Engineering Questions and Answers for Campus interviews focuses on “Evolutionary Software Process Models”.
1. Which one of the following is not an Evolutionary Process Model?
a) WINWIN Spiral Model
b) Incremental Model
c) Concurrent Development Model
d) All of the mentioned
View Answer
Explanation: None.
2. The Incremental Model is a result of combination of elements of which two models?
a) Build & FIX Model & Waterfall Model
b) Linear Model & RAD Model
c) Linear Model & Prototyping Model
d) Waterfall Model & RAD Model
View Answer
Explanation: Each linear sequence produces a deliverable “increment” of the software and particularly when we have to quickly deliver a limited functionality system.
3. What is the major advantage of using Incremental Model?
a) Customer can respond to each increment
b) Easier to test and debug
c) It is used when there is a need to get a product to the market early
d) Easier to test and debug & It is used when there is a need to get a product to the market early
View Answer
Explanation: Incremental Model is generally easier to test and debug than other methods of software development because relatively smaller changes are made during each iteration and is popular particularly when we have to quickly deliver a limited functionality system.However, option “a” can be seen in other models as well like RAD model,hence option “d” answers the question.
4. The spiral model was originally proposed by
a) IBM
b) Barry Boehm
c) Pressman
d) Royce
View Answer
Explanation: None.
5. The spiral model has two dimensions namely _____________ and ____________
a) diagonal, angular
b) radial, perpendicular
c) radial, angular
d) diagonal, perpendicular
View Answer
Explanation: The radial dimension of the model represents the cumulative costs and the angular dimension represents the progress made in completing each cycle. Each loop of the spiral from X-axis clockwise through 360o represents one phase.
6. How is WINWIN Spiral Model different from Spiral Model?
a) It defines tasks required to define resources, timelines, and other project related information
b) It defines a set of negotiation activities at the beginning of each pass around the spiral
c) It defines tasks required to assess both technical and management risks
d) It defines tasks required to construct, test, install, and provide user support
View Answer
Explanation: Except option “b” all other tasks/activities are present in Spiral Model as well.
7. Identify the disadvantage of Spiral Model.
a) Doesn’t work well for smaller projects
b) High amount of risk analysis
c) Strong approval and documentation control
d) Additional Functionality can be added at a later date
View Answer
Explanation: All other options are the advantages of Spiral Model.
8. Spiral Model has user involvement in all its phases.
a) True
b) False
View Answer
Explanation: None.
9. How is Incremental Model different from Spiral Model?
a) Progress can be measured for Incremental Model
b) Changing requirements can be accommodated in Incremental Model
c) Users can see the system early in Incremental Model
d) All of the mentioned
View Answer
Explanation: None.
10. If you were to create client/server applications, which model would you go for?
a) WINWIN Spiral Model
b) Spiral Model
c) Concurrent Model
d) Incremental Model
View Answer
Explanation: When applied to client/server applications, the concurrent process model defines activities in two dimensions: a system dimension and a component dimension.Thus Concurrency is achieved by system and component activities occurring simultaneously and can be modeled using the state-oriented approach.
