What Requirements Should Be Like to Implement Software Nonfunctional Issues Appropriately?
Nonfunctional characteristics of a software product are as important as functional ones. But sometimes they are neglected during development process or mobile testing, desktop testing or web site testing. Such application cannot be successful in production.
So, to create a good application one must implement all the needed nonfunctional issues. The best way to do it is to rely on the project requirements. It means that the requirements must be elaborated appropriately.
In this case not only developers will know what they must do, but also a software testing company will be able to make necessary preparations and elaborate suitable test procedures.
It is a good idea to create the list of nonfunctional criteria that are similar for the whole project. Then there will be no necessity to write them in every requirement. It is essential to record the requirements in details and clearly.
Requirements documentation should include:
1. Description of Nonfunctional Aspects for Each Function
It is convenient to write nonfunctional issues with the description of the related function.
2. A Set of Common Nonfunctional Aspects of the Project
There should be the list of nonfunctional issues, applicable to the whole project, for instance, operation systems or browsers, with which the application must be compatible.
If software requirements are competently elaborated, a mobile application testing, desktop testing or web site testing will be less time and resources consuming and chances for a project to be successful will significantly increase.
