Characteristics of Requirements
To ensure that both developers and customers understand the requirements properly, it is important that the requirements be of high quality. To this end it is to be checked that the requirements should have the following characteristics.
1. Requirement Correctness: T o be sure about requirements correctness both developer and the customer should review them that they are stated without any error.
2. Consistency of Requirements: Consistency of requirements does mean no conflicting or ambiguous requirements. For an example, if one requirement states that a maximum of 5 users can use system at one time. And another requirement says that in a certain situation there may be 20 simultaneous users, those requirements are said to be inconsistent. In other words, two requirements are inconsistent if it is possible to satisfy them simultaneously.
3. Requirement Completeness: The set of requirements is complete if all possible states. State changes inputs products and constraints are described in the form of requirements. A system description is externally complete if the system if the system description contains all the information about the environment desired by the customer. A requirement description is internally complete if there are no undefined references among the requirements.
4. Realistic Requirements: Realistic requirements are the one which are possible to be performed practically. For an example, suppose a system requires user access to a main computer located several thousand miles away and the response time for remote users is be the same as for local users ( those whose wor4kstations are connected directly to the main computer) . this requirement may be unrealistic, since extra time may be required for transmission over communication lines
5. Appropriateness of Requirements: Sometimes a requirement restricts the developers unnecessarily or includes function there not directly related to the problem at hand. For an example, a general may decide that a tank new software system should allow soldiers to send and receive electronic mail even though the main purpose of the tank is to traverse uneven terrain. We should review the requirements to retain only those that work directly to solve customer problem.
6. Verification of Requirement: we must be able to write test cases to demonstrate that the requirements have been met or not.
7. Traceability of Requirements; each system function should be traced to set of requirements that mandates it. It will be easy to find the set of requirements that deals with a specific aspect of the system. For example to review all communications requirements, all requirements would need to be read. We can use this checklist to search for each possible requirement improving and changing as we go. The above discussed characteristics should be present in the software requirements, so that the software product will meet all the mentioned requirement of the user.
