6 Additional information required from potential suppliers

The requirements define carefully the functions that need to be carried out by the new application and all the necessary inputs and outputs for these functions. The requirements should also state any standards with which there should be compliance, and the existing systems with which the new system needs to be compatible. As well as these functional requirements, there will also need to be operational and quality requirements concerning such matters as the required response times, reliability, usability and maintainability of the new system.

In general, the requirements document should state needs as accurately as possible and should avoid technical specifications of possible solutions. The onus should be placed on the potential suppliers to identify the technical solutions that they believe will meet the customer's stated needs. After all. they are the technical experts who should have access to the most up-to-date information about current technology.

liach requirement needs to be identified as being either mandatory or desirable.

• Mandatory If a proposal does not meet this requirement then the proposal is to be immediately rejected. No further evaluation would be required.

• Desirable A proposal might be deficient in this respect, but other features of the proposal could compensate for it.

For example, in the case of the Brightmouth College payroll acquisition project. Brigette might identify as a mandatory requirement that any new system should be able to carry out all the processes previously carried out by the old system. However a desirable feature might be that the new payroll software should be able to produce accounting details of staff costs in an electronic format that can be read directly by the college's accounting computer system.

Among the other details that should be included in the requirements document to be issued to potential suppliers would be requests for any information needed to help us judge the standing of organization itself, litis could include financial reports, references from past customers and the CVs of key development staff.

Some of these issues were touched on in Chapter 3 on project evaluation.
