- Describe the main qualities of a good requirement.
There are several qualities regarding a good requirement but the most outstanding ones include the:
Clarity – the requirement should be clear enough to be understood by its users.
Understandable – the requirements should be put in a manner easy to understand by users of all levels.
Consistent – the requirement should be such that it doesn’t contradict itself, it is important noting that during system development, all users need to be consulted, including the managers as well as the junior staff, one would find that the managers would like a wider control of the system so as to monitor the junior staff to the date whereas the junior staff are objecting these view, hence a contradiction. When this issue is not considered carefully, usually through consultation or negotiation either the managers or junior staff may resent the system thus by this, once the users resent the system, obviously it will not be exploited to the maximum thus lowering the benefits the organization derives from it thus consistency must always be considered in the system development requirements.
Verifiable – The requirements of a given system should always be verifiable as in they should be put in a manner that can be checked across in future so as one can clearly identify whether the particular requirement has been met or not, it is usually advised that the requirements are put in a manner that during verification, the answer is either true or false and nothing vague as it is during this stage that legal action can be taken by the either the contractor or client if at all the answer is no and always with the law, matters of doubt are generally not recommended.
