Agility is a term used in many works in the context of information systems. When studying the concept closer, it became obvious that there is a terminological heterogeneity preventing a common definition whilst at the same time not preventing the frequent use of the term. In order to approach the term in a structured way, the following two paths were chosen. Firstly, the term was traced back to its roots which showed its first appearance in organisational theory. Secondly, the major IS conferences (ECIS and ICIS) and the requirements engineering conference as a major computer science conference were analysed from 2001 when the agile manifesto was published which led to a wave of works on agility. The descriptive results are presented in the paper.
