A. Spiral
B. Waterfall
C. RAD
D. Iterative Enhancement Model

Explanation: Relying on risk assessment/analysis provides more flexibility than required for many applications which overcomes the criteria of less experienced developers.

A. Requirements
B. Development team & Users
C. Project type and associated risk
D. All of the mentioned

Explanation: Each model has to have some requirements, a team of developers, users and the risk involved in develog a project

A. the more tedious its removal becomes
B. the more costly it is to detect and correct
C. the less likely it is to be properly corrected
D. All of the mentioned

A. Software Verification
B. Software Validation
C. Software design and implementation
D. Software evolution

A. Transition
B. Elaboration
C. Construction
D. Inception

A. It shows the process activities that are enacted
B. It suggests good practices to be used during the process
C. It shows the phases of the model over time
D. All of the mentioned

A. scalability
B. usability
C. reusability
D. reliability

Explanation: rest all are external qualities which are visible to the user.

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

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

Explanation: Except option “b” all other tasks/activities are present in Spiral Model as well.

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

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.
