Software Requirements Specification (SRS): Brief Overview of Document 2022

If you ever dealt with the development of an application, you surely know that it is hardly possible to meet all the client’s requirements without proper documentation. In this article, we try to help you to create a perfect Software Requirements Specification that will be an indispensable part of your development process.

Why Is SRS Important?

Software Requirements Specification (SRS) is a document that clarifies the requirements of the future project in the smallest details. It explains which features must be included and how the application must work after it is developed.

Such a document is one of the most important as it reduces the number of discussions which helps to save a lot of time. It also clarifies everything in detail and decreases the misunderstanding of what helps to provide the right product and meet customers’ expectations.

This document helps a lot of developers as it allows them to:

• evaluate the final price of the project;
• create the work plan and determine how much time they need for the development process;
• choose the right programming stack which will help to implement the required application’s features;
• create a test plan and make a testing process in keeping with the customer’s outcome desires.

What Does an SRS Document Consist of?

This document clarifies all the features and implicates essential information needed in the end project and the proper description of how it must work.

This kind of document consists of:

• All the functions needed to be included in the completed project and how they will interconnect to ensure stable operation of the application.
• The calculated productivity of the software is accurately calculated. Among such options can be loading time, amount of users which can be handled.
• How it is compatible with different devices and other software. It helps a lot to see how flexible the application is.
• Test options will be used by testers to estimate the productivity of the software.
• The interface of the application. It is important to provide all the information about the desirable interface to make the application with a nice user interface and convenient navigation.
• Point out the environment in which the software will work. It will help to determine the limitations and its maintenance when it is completed.

Functional vs. Technical Requirements of SRS

Functional requirements of SRS. Those are the ones that help the end-users to do some specific tasks. It describes how every part of the software works and how it will achieve the expectations with the choice of specific inputs by users. It also includes ways of data input and processes required for the data computation.

Technical Requirements of SRS. Those are non-functional requirements that may not influence how the software will operate, but as it contains important details, it influences user experience. Among such requirements can be the following:

• Availability. It is a website that shows how often it will be online.
• Usability. This requirement is about user experience(feelings about the interaction with the website) and user interface(ease of use, layout of the website components).
• Security. This requirement shows how secure the software is.
• Performance. It defines how productively it will work with the real figures. It is noted in SRS what is the minimum productivity needed for this software.
