Independent Service Heuristics: a rapid, business-friendly approach to flow-oriented boundaries
Matthew Skelton and Nick Tune
This session is an experience report of using a technique called Independent Service Heuristics to provide a rapid, low-fidelity, business-friendly approach to finding possible team and service boundaries for fast flow. The Independent Service Heuristics (ISH) are rules-of-thumb (clues) for identifying candidate value streams and domain boundaries by seeing if they could be run as a separate SaaS/cloud product. Developed by the authors of the book Team Topologies (Matthew Skelton and Manuel Pais), and elaborated by organisations and members of the DDD community, the ISH approach is particularly suited to situations where stakeholders want rapid results and are sceptical of terminology-heavy approaches used by some DDD practitioners. We describe a recent engagement with a large retail customer in North America where we used ISH and DDD techniques in parallel for multiple perspectives on a challenging situation.
