"Independent Service Heuristics: a rapid, business-friendly approach to flow-oriented boundaries - Matthew Skelton & 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.
Matthew Skelton is co-author of Team Topologies: organizing business and technology teams for fast flow. Recognised by TechBeacon in 2018, 2019, and 2020 as one of the top 100 people to follow in DevOps, Matthew curates the well-known DevOps team topologies patterns at devopstopologies.com. He is Head of Consulting at Conflux and specialises in Continuous Delivery, operability, and organisation dynamics for modern software systems.
Nick works with technology leaders to map strategy, architect systems, and build continuous delivery teams. He is the co-author of Principles and Practices of Domain-Driven Design (2014), and Architecture Modernization: Product, Domain, and Team-oriend (2022).
How many ISH questions could be answered by just looking at Wardley map alone (with 3 verticals and 1 horizontal), without running Event Storming sessions?
That's a nice question, Jan. The ISH technique does relate to Wardley Maps but ISH is an easier "way in" compared to Wardley Maps, in my experience. They are complimentary techniques.
I would add some others heuristics
What heuristics would you add? We wanted to keep the totat number to no more than 10.
