HW8: Chapter 2


2.1. Suggest the most appropriate generic software process model that might be used as a basis for managing the development of the following systems. Explain your answer according to the type of system being developed:

A system to control antilock braking in a car
I believe a waterfall method would be the best software process because, as the text states, safety-critical software is usually developed using a waterfall process because the requirements have to be heavily analyzed before development begins and since safety is a main requirement of a car’s antilock brake system, it’s requirements are unlikely to change during development.

A virtual reality system to support software maintenance
A software system that focuses on providing maintenance for other systems would likely require an incremental development process as during development the systems that it would be designed to maintain would also likely change. Incremental development would allow for agile development and would have lower costs to make changes if they are needed.

A university accounting system that replaces an existing system
The integration and configuration design process should be used because since there is already an existing accounting system, the new system will likely be able to reuse code during development.

An interactive travel planning system that helps users plan journeys with the lowest environmental impact.
Incremental development would be an appropriate choice as feedback from users could cause the requirements of the travel planning system to change during the development process and incremental development would be cheaper to change than other development methods.

HW6: Chapter 4

1.       4.5.  Using the technique suggested here, where natural language descriptions are presented in a standard format, write plausible user requirements for the following functions: o     An unattended petrol (gas) pump system that includes a credit card reader. The customer swipes the card through the reader, then specifies the amount of fuel required. The fuel is delivered and the customer’s account debited. Function: Accept customer input for the amount of gas they want and charge them for it Description: The system will accept a customer’s credit card, allow the customer to specify the amount of gas they want, dispense the gas, and charge the customer for the gas Inputs: Customer credit card information, amount of gas that the customer specified Source: The card reader Outputs: The amount of gas that the customer specified Destination: The customer’s car’s gas tank. Action: The customer will swipe their card through ...

6.4.  Draw diagrams showing a conceptual view and a process view of the architectures of the following systems: ·          A ticket machine used by passengers at a railway station. Conceptual view: Process view: ·          A computer-controlled video conferencing system that allows video, audio, and computer data to be visible to several participants at the same time. Conceptual view: Process view: ·          A robot floor-cleaner that is intended to clean relatively clear spaces such as corridors. The cleaner must be able to sense walls and other obstructions.
