Question 6

A model is a representation of an important aspect of the real world.

True

False

Question 7

What is a methodology?

A methodology explains the how to do something.

A methodology is something that is used, possible as part of the technique.

A methodology is an abstraction of the real world that is produced, often by a tool.

A methodology covers the entire process of development and defines the appropriate techniques, models, and tools to be used.

Question 10

A project that has low technical risk should use the predictive approach.

True

False

Imagine you are given a description of a new project. How would you decide if a Predictive versus Adaptive SDLC variation should be used?

		predictive approach
		persistent approach
		gathering approach
		adaptive approach

Solution

1. adaptive approach. As the users start using the system, new requirements would arise and system needs to enhance.
2. Gathering requirements is part of collecting requirements at the start of SDLC.
3. Predictive. Requirements are not clear, so software is developed based on basic understanding b/w engineer and user.
4. Agile development. Agile follows spring model where tasks are taken in 1-2 weeks sprint. It is used where requirements changes continuously. Most of the good companies are following this SDLC.
5. Predictive and Adaptive. Requirements are not clear in predictive so basic prototype is developed first. However, requirements are pretty much clear in case of Adaptive so whole system is developed and enhanced when new requirements arise.
6. True. Model represents an entity in real world.
7. A methodology covers the entire process of development and defines the appropriate techniques, models, and tools to be used.
8. False. Walking skeleton is just a prototype. In this case system is being built, tested and then enhanced.
9. True. Looking at basic modules of a complex problem simlifies it.
10. False. If problem is not complex and can be developed easily then adaptive approach would be used

Predictive approach would be used where requirements are not very clear, vice-versa in case of adaptive approach.
