Basic ideas about software requirements specification: importance!


Writing requirements becomes a rather exciting task. In any project, good requirements provide the development of a clearer, and cohesive system that is closer to achieving customer satisfaction within the agreed budget and deadline. Keep reading to understand more regarding software requirements specifications.

Software Requirement specification – what is it?

  • The ability which the user must be able to achieve the primary objective, or solve the problem.
  • The capability which must be possessed or met through a component or system to understand standard, a contract, other generally imposed document, and specification.
  • The set of all requirements that form the basis for the subsequent development of software or software components.

Therefore, it would be the need of a user / client, business requirements, company desires, company request, carried out by a system or product. So the application must meet these premises: needs, requirements, desires and requests, using as leading tool to provide a system, application / solution for a product.

What is the requirements engineering process?

The process begins with the elicitation of data, which is collected through interviews, documents, meetings, workshops, prototyping and etc.

Requirements elicitation and analysis – It is worth mentioning that the requirements are fundamental for both price estimation, and for modelling, design, implementation, tests and also maintainability. In this way, the requirements become intrinsic to the software life cycle.

Requirements Specification – Software requirements specification may contain functional and non-functional requirements, and even a use case diagram or prototyping of part of the product. The functionality of each feature is described step by step as well as its restrictions.

Requirements Validation – After writing the customer / user’s needs, it is important that you validate this data, either through a meeting by having those responsible sign the document so that it can be valid, or by acknowledging the responsibility of the requirements raised by email. This step is also for corrections and other functionality can be discovered / included.

Requirements Document

The document serves to present an overview and functional of the product. It contains –

  • Introduction
  • Product overview
  • Specific technical terms for a given context
  • Abbreviations and acronyms
  • Involved and Users
  • Requirements (Functional, Non-Functional and Business Rules)
  • Use case
  • Attachments (prototypes, architecture and supporting documents).

In addition, the experts focus on the collection and organization of all requirements that involve the project. If you have a Requirements Management Plan, you should consult with them to determine the correct location and organization of the requirements.
