What is the first phase of the waterfall model?

• Integration and system testing

• Implementation and unit testing

• Requirements analysis and definition

• System and software design

What is a main drawback of the waterfall model?

• It is suitable for all types of projects

• It is flexible in accommodating changes

• It allows for rapid customer feedback

• It is difficult to respond to changing customer requirements

In which scenario is the waterfall model mostly used?

• Projects with highly unstable requirements

• Agile development environments

• Large systems engineering projects

• Small software applications

What is a benefit of incremental development?

• Higher costs for accommodating changes

• Less customer involvement

• More rapid delivery of useful software

• Longer time to gain customer feedback

What happens to the amount of analysis and documentation in incremental development compared to the waterfall model?

• It remains the same

• It is much less

• It increases significantly

• It becomes irrelevant

The incremental development model:

• Follows a rigid sequence of steps

• Integrates specification, development, and validation

• Is only used for scientific software

• Does not involve user feedback

One key benefit of incremental development is:

• Reduced cost of accommodating changing requirements

• Increased rigidity in design

• Delayed user feedback

• No need for software testing

In incremental development, what is a common problem?

• Code cannot be modified

• System structure degrades as new increments are added

• Documentation is extensive and time-consuming

• No testing is performed

What is the main characteristic of reuse-oriented software engineering?

• System is developed from scratch

• No prior system components are used

• System is assembled from existing components

• There is no system design phase

Which is NOT a type of software component used in reuse-oriented software engineering?

• Web services

• Collections of objects

• Handwritten assembly code

• Standalone software systems
