MISY 301

Requirement writing

Read the following questions carefully and make the required analysis and research required to solve them and present your solution in the most appropriate way you can.

Q1. Using the technique suggested in chapter 3, where natural language descriptions are presented in a standard format, write plausible user requirements for the following functions:

§  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.

§  The cash-dispensing function in a bank ATM.

§  The spelling-check and correcting function in a word processor.

Q2. Rewrite the following description using the structured approach described in this chapter. Resolve the identified ambiguities in an appropriate way.

An automated ticket-issuing system sells rail tickets. Users select their destination and input a credit card and a personal identification number. The rail ticket is issued and their credit card account charged. When the user presses the start button, a menu display of potential destinations is activated, along with a message to the user to select a destination. Once a destination has been selected, users are requested to input their credit card. Its validity is checked and the user is then requested to input a personal identifier. When the credit transaction has been validated, the ticket is issued.
