A short biography.
I’m a process pragmatist — I value intent and outcome over method and precedent.
Between 2007 and 2022 (with a two-year break) I was Supportability & Transition Management Lead inside Shell’s Global IT Services and Application Management group. S&TM was the response to the troublesome operation of a number of new global applications — our aim was to engage early in projects to ensure operational readiness. The tooling I wrote in those years has since been the basis for the enterprise-wide toolset, and S&TM has taken a prominent role in Shell’s project delivery framework.
Opsasto, and how it began.
By 2016 I had written down enough of what I’d learned that the write-up needed a name. Opsasto became the framework, and a blog at opsasto.blog the place where I thought aloud about it.
Opsasto is a structured, risk-based and scalable approach for assuring the quality of an IT service and its operation. The methodology enhances operational readiness at the point of go-live by looking at eight assurance areas. // from the original write-up, 2016

I write infrequently — when something is worth writing down. The archive of about thirty pieces lives in writing; the canonical blog at blog.dimitrigeelen.com; professional history on linkedin. For engagements: contact.
