Despite a profusion of literature on Complex Adaptive System (CAS) definitions, it is still challenging to definitely answer whether a given system is or is not a CAS. The challenge generally lies in deciding where boundaries lie between complex systems and CAS. In this work, we propose a novel definition for CAS in the form of a concise, robust, and scientific algorithmic framework. The definition allows a two-stage evaluation of a system to first determine whether it meets complexity-related attributes before exploring a series of attributes related to adaptivity, including autonomy, memory, self-organisation and emergence. We demonstrate the appropriateness of the definition by applying it on two case studies in the medical and supply chain domains. We envision that the proposed algorithmic approach can provide an efficient auditing tool to determine whether a system is a CAS, also providing insights to relevant communities to optimise their processes and organisational structures.
