Don’t Jump Off The Roof Dad!
I recently posted a link to a news article with the title “Spreadsheet error led to Edinburgh hospital opening delay”, which you can find here. There was a great response to this post so thanks to everyone who interacted with it. Flippantly I suggested the experience of this project was good evidence for adopting a Model-Based […]
Break! Break! Break!
I’ve just been participating in a virtual seminar with Dassault Systèmes hosted by the Crystal Interactive JAM Platform when the unthinkable happened. I had just delivered a whistle-stop presentation on the subject of “Identifying the right MBSE Strategy” (MBSE = Model-Based Systems Engineering) when something went wrong and I lost my connection!

What could go wrong? Currently we’re having some building work done […]
More, More, More! Thoughts on Scope Creep
In my last article “Building Systems is Difficult” I discussed the “3 Evils” of Systems Engineering, namely: Complexity, A lack of understanding, and Poor Communication. There were lots of great comments on this, but one which stood out for me as something which required further discussion was this from James McHugh who added (as an additional evil and […]
