Do you know anyone who is new to process modelling or has been modelling for a while but without formal training? I've created a YouTube channel where I'll be uploading short tutorials. Here's the first: youtu.be/DcLAZfNRSk4 #ProcessModel #ProcessModelling #ProcessModeling

...Rules might contradict each other or even be missing and they won’t know because they have no way of validating them before they automate them in software. So computer ends up saying “No” when it should say “Yes, simply because people are not trained to articulate complexity.

In the 80s, I wrote a thesis titled "Greek Infantry and Cavalry with Special Reference to the 5th Century BC". My supervisor, Professor Richmond, died this year and I posted this comment on the death notice on Facebook. I use the skills he instilled in me in my work today.

I have rarely been on a project where they don't point at a physical database design when I ask about the logical data model (and then look nonplussed when I say I want to see a technology-agnostic model). Not even Google gets it when you search for "logical data modeling tools".

But unless executive sponsors recognise the need for such blueprints, and skilled people to produce them, they will have to continuing living with the software equivalent of these: 16/16

Executive sponsors seem to be willing enough to spend money fixing the software equivalent of these construction errors, despite the fact that discovering and fixing those mistakes at the blueprint stage is both faster and cheaper. 15/16

The situation isn't helped when some BPM tool providers certify people as "Business Architects" after a three-day course and zero experience. Recently, a Lead Systems Architect took such a course, got a job as a BA and then rang me to ask what he should do on the project. 14/16

But so many models I see, produced by "experienced" people, reflect all the design problems mentioned above: incomplete, uncoordinated, missing details, personal notation. This diagram was produced by a process designer with 20 years' "experience". Comments are mine. 13/16

Even when there is something resembling a blueprint, it is often produced by people who have not been given the skills. EG: just as everyone thinks they can draw a picture of a house, everyone seems to think they can draw a process model without any training. 12/16

Could you be certain the house would stand the test of time? Or not end up a sorry mess of features bolted tactically onto other features? 6/16
