The main purpose of this document is to provide a working example of a Software Requirements Specification (SRS) based on ISO/IEC/IEEE 29148:2018 standard.
Note: This is an example document, which is not complete.
This document specifies requirements for a simple application for requirements management of software and system products.
The application allows users to:
The application stores documents as human readable files with open file format.
The application runs offline without connection to any server.
Note: The application functionality corresponds to ReqView v1.0 released in 2015. Check all advanced requirements management features it offers now.
The application runs in the latest version of Chrome or Firefox browser on Windows, Linux and Mac.
The application GUI provides menus, toolbars, buttons, panes, containers, grids allowing for easy control by a keyboard and a mouse.
The application allows import a structured MS Word document via HTML data format.
The application allows populating a MS Word document with project data via HTML data format.
The application allows import / export a list of requirements from / to MS Excel sheet via CSV data format.
The application stores project data in JSON format to enable easy integration with 3rd party applications.
Product functions are summarized in Section 2. User Stories of NEEDS document.
Custom Attribute: Additional requirement property capturing additional requirements properties such as requirements source, status, priority, verification method, fit criterion, ...,
Document: A structured requirements specification capturing textual requirements for a given product or service.
Link: A directed association between related requirements allowing to analyze requirements coverage, gaps and impact of changes.
Link Type: Property of traceability links allowing to analyze links with different semantic independently, e.g., satisfaction and verification links.
