Software Requirement Specification

When eLink is approached to design, develop, and support large custom systems, from WordPress intranets to complex data matching software, our approach is to first create a Software Requirement Specification document. The purpose of a Software Requirements Specification (SRS) document is to create a detailed description of the requirements for the solution to be developed for any client. It illustrates the purpose, workflow, and capabilities of the application and explains system constraints and intended purposes of functions, as well as define interactions with external applications. 

  • Overall Description

  • Specific Requirements

  • Encryption & Security 

  • Maintainability & Portability 

  • Networking, Hardware & Firewall Considerations 

  • Design Constraints 

  • Database Requirements 

  • Other Requirements

Software Requirement Specification


A detailed look at the user needs of the system is always a primary focus of the Software Requirement Specification. Before any code is written for large systems, understanding who is using the platform, what they need to use it for, and how they need to use it can help to prioritize specific features and anticipate any potential hurdles that might have been encountered without such a document.

Once the users' needs of the system have been detailed and outlined, the document lays out any assumptions that developers have about how the systems should work as well as any dependencies that have to be relied upon in order to make the system function. Assumptions can include any hardware, servers, dependencies on third party software, or anything else that is required in order to keep the system operating in a way that satisfies the users’ needs as previously defined.

The specific requirements of the SRS document details a comprehensive description of the development that needs to be completed, how it will work together with the previously defined assumptions and dependencies, as well as how the user will use the system. The granularity of the SRS dives into each dropdown, button, page, and how each piece functions and connects to one another.

The final document is primarily intended to be a blueprint for the entire project. We create detailed requirements and high level design to be used for the purpose of developing state of the art web applications which incorporate any existing features while adding any desired and proposed enhancements, structural back-end changes, or complementary iOS and Android apps for a superior user experience.
