Chapter 2, Problem 2.1E

Explanation of Solution

A system to control anti-lock braking in a car:

• The most appropriate generic software process model for controlling anti-lock braking in a car is Waterfall model.
• The anti-lock braking is a safety-critical system.
• In the waterfall model, for the proper functioning of the anti-lock braking system of the car, the analysis and design requirements must be scheduled without any flaws before the system implementation.

A virtual reality system to support software maintenance:

• The most appropriate generic software process model for a virtual reality system to support software maintenance is Incremental development.
• The system requirements keeps on changing and it cannot be predicted before the implementation and it requires complex programming for the software.
• This software is not a critical system.

A University accounting system that replaces an existing system:

• The most appropriate generic software process model for a University accounting system that replaces an existing system is Waterfall model.
• Because of the existing system, the system requirements can be predicted.
• This is mission-critical system and the requirements are stable and reusable.

An interactive travel planning system that helps users plan journeys with the lowest environmental impact:

• The most appropriate generic software process model for an interactive travel planning system is the prototype model and incremental development model.
• The requirements of the user may change and fast delivery is essential to be implemented.
• Therefore, the prototype model will save the development time to focus on essential function first to be later completed.
