Summary
An IT team spread across the ITIL v4 framework's 34 practices needs a single foundational thing it commits to getting right, then builds outward from there. David van Heerden names his top four candidates: risk management, service desk, deployment, and infrastructure and platform management. He draws on Gary Keller and Jay Papasan's book The One Thing to explain why each could be that one thing. His method for choosing: engage your business stakeholders, have them score how much they value each practice, and let that conversation surface the one thing worth your investment.
