Omissions in a ticket issuing system

For example, a real-time control system in an aircraft has safety as its principal priority; an interactive game has responsiveness and usability as its priority. Its validity is checked and the user is then requested to input a personal identifier.

The techniques used to achieve safety are not required for interactive gaming; the extensive UI design required for games is not needed in safety-critical control systems.

Ambiguities and omissions include: All these are availability requirements — note that these vary according to the time of day. You may find it helpful to base your answer on the list of management activities in Section Because of all software systems have common quality attributes, including availability, modifiability, performance, security and safety, testability and usability, the fundamental software ideas provides common solutions or tactics to support those qualities.

The system requirements are developed after user requirements have been established. Write a set of non-functional requirements for the ticket-issuing system, setting out its expected reliability and response time.

You can create any fair assumptions about the system. Ambiguities and omission include different points such as: Journey begins on a day and will be over with one rest among. No receipt is granted for the money transacted. When the credit transaction has been validated, the ticket is issued.

Systems which are very expensive to change need extensive upfront analysis to ensure that the requirements are consistent and extensive validation to ensure that the system meets its specification.

Rewrite the above description using the structured approach described in chapter 4 of the textbook. The rail ticket is issued and their credit card account charged.

If anything goes wrong, the contractor has to pay. The essential difference is that in generic software product development, the specification is owned by the product developer. Answer; First, we should realize that to keep track the relationship between the functional and non-functional requirements is difficult.

The techniques used to develop short-lifetime, rapid delivery systems e. Real-time systems usually involve many hardware components which are not easy to change and cannot be incremental.

All these are availability requirements — note that these vary according to the time of day. The passenger is a passive user-actor who initiates the procedure and obtains the ticket san objective of measurable value.

Write a set of non-functional requirements for the ticket-issuing system, setting out its expected reliability and response time. Some systems have to be delivered quickly if they are to be useful. Suggest why it is important to make a distinction between developing the user requirements and developing system requirements in the requirements engineering process.

List the inconsistencies, ambiguities, or omissions in the above statement of requirements. Explain why the best programmers do not always make the best software managers. Therefore, a reuse-based approach is likely to be appropriate for this.
