Synopsis

System requirements are usually written in unconstrained natural language (NL), which is inherently imprecise. Often, requirements authors are not trained in how to write requirements. During system development, requirements problems propagate to lower levels. This creates unnecessary volatility and risk, impacting programme schedule and cost. The Easy Approach to Requirements Syntax (EARS) is a mechanism to gently constrain NL requirements.

The EARS patterns provide structured guidance that enable authors to write high quality textual requirements. EARS requirements have a set syntax (structure), with an underlying ruleset. A small number of keywords are used to denote the different clauses of an EARS requirement.

The clauses are always in the same order, following temporal logic. The syntax and keywords closely match common usage of English and are therefore intuitive. EARS reduces or even eliminates common problems found in NL requirements. EARS has proved popular with practitioners because it is lightweight, there is little training overhead, no specialist tool is necessary, and the resultant requirements are easy to read.

EARS is used worldwide by large and small organisations in different domains. These include blue chip companies such as Bosch, Daimler, Honeywell, Intel, Rolls-Royce and Siemens.

The notation is taught at universities around the world including in China, France, Sweden, UK and USA. This presentation will give an overview of the key concepts of EARS and provide examples of EARS requirements.
