The defining task in the life cycle of modern software and hardware complexes of automated systems has become the provision of the required quality of software. System errors when determining the necessary and sufficient quality characteristics, assessing labor costs, cost and terms of creating software tools are very common.

As a result, the created software and hardware systems automated systems do not meet the required volume of their destination. They take a long time to refine to achieve the required quality of functioning, which leads to additional cost and time.

The use of a systematic analysis and coordination of the composition of requirements for the properties and values of the quality characteristics of software tools will allow avoiding inappropriate overestimation of requirements and use of resources, as well as unjustified reduction, accidental omissions, gaps and uncertainties in the composition and content of technical specifications approved by the customer.

The requirements specification serves as the basis for further planning, design and coding. Such as performance, safety and usability by As well as the basis for testing user documentation. However, it should not contain design, engineering, testing. And it’s project management details except for known design and implementation constraints. 

Even those working on agile projects need some information. It’s from a good software requirements specification. Typically, these developers do not collect all this information in a coherent material. But the requirements specification template serves. It’s a as a handy reminder of what knowledge might need to be gathered. This chapter ends with a section. It describes the specification of requirements in agile projects.

Attention! Requirements material alone often does not meet the needs of all audiences. Some people only need to know the business goals. Others want a high-level big picture. Others are only interested in the vision from the user’s point of view. But there are also those who need all the details. This is why we strongly recommend creating materials. Such as a concept paper and project boundary document, a user requirements document. And it’s a software requirements specification. Do not expect all user representatives to read the detailed software requirements specification. And don’t expect developers to learn everything they need to know from a set of use cases or user stories.

Here are some tips on how to make the requirements clear and understandable:

  • use the appropriate template to structure all the necessary information;
  • sections, subsections and individual requirements should be named consistently;
  • use visual emphasis consistently and reasonably; Remember that color highlights may not be visible to people with color blindness or black and white printing;
  • create a table of contents to make it easier for users to find the information they need;
  • number all figures and tables, head them and, referring to them, use the assigned numbers;
  • If, when storing requirements in a document, you refer to other parts of the document in the document, use the cross-referencing capabilities in your editor, and not the complex page encoding;
  • if you are using documents, use hyperlinks so that the reader can quickly jump to the relevant sections of the specification or other files;
  • When storing requirements in a specialized tool, use links to make it easier for the reader to navigate the information you need;
  • include graphical representations of information where possible to facilitate understanding;
  • use the services of an experienced editor to ensure document consistency and consistency in terminology and structure.

It is not necessary to write a specification for the entire product. But it is necessary to document the requirements for each iteration. So it’s important before creating it. This is convenient if at the beginning of the work the project participants could not define all the requirements. And some functionality needs to be quickly transferred into the hands of users. Feedback from early iterations allows the remainder of the project to be adjusted. For any project, you need to reach a basic agreement. It’s related to each set of requirements before developers begin implementing them.
