Ten Years of EARS

The first easy Approach to Requirements Syntax (EARS) paper was published 10 years ago.1 (For more information, see "Introduction to the Easy Approach to Requirements Syntax.") As the original authors, we were initially unsure about publishing because we thought that EARS was too simple: almost too obvious to be of value. It turns out that it is this simplicity that is perhaps the greatest strength of EARS. Here we reflect on 10 years of EARS and share some lessons learned. Experienced EARS practitioners provide case studies to illustrate some applications of the approach. (For more information, see "The Easy Approach to Requirements Syntax for Agile Cyberphysical System Development," "Applying the Easy Approach to Requirements Syntax to Regulatory Requirements in the Nuclear Energy Domain," and "Intel Corporation.")
