Details

Easy Approach to Requirements Syntax (EARS) was developed at Rolls-Royce and has been shown to drastically reduce or even eliminate the main problems typically associated with natural language (NL) requirements. It is widely used in academia and in a range of industries throughout the world.

System requirements are usually written in unconstrained NL, which is inherently imprecise. During system development, problems in system requirements often propagate to lower levels. This creates unnecessary volatility and risk, which impact programme schedule and cost. To mitigate this problem, there is a need to provide simple, practical guidance for authors of NL requirements. EARS is a notation for authoring NL requirements through the application of a template with an underlying ruleset. Application of EARS produces requirements in a small number of simple patterns. EARS has proved popular with practitioners because it is lightweight, there is little training overhead, no specialist tool is required and the resultant requirements are easy to read.

This presentation will introduce the EARS approach, illustrate worked examples and discuss the benefits of adopting the approach.
