Welcome to Scarecrow Consultants Limited


Scarecrow Consultants are a tool-independent model-based systems engineering consultancy, formed in 2014 by Prof Jon Holt and Simon Perry with a mission to

‘promote the use and application of Model-Based Systems Engineering (MBSE) in businesses worldwide, by pioneering new and pragmatic techniques for MBSE in the real world'

All Scarecrow Consultants are true experts in the theory and real-life application of MBSE and are recognised at an international level.





As part of our response to the current crisis, to support the MBSE community and to try to avoid MBSE-ers everywhere going stir crazy, Scarecrow Consultants would like to announce two new regular free on-line events!

Starting from next Thursday April 2nd we will run two regular weekly events:

• 1000 – 1045 – a free talk and presentation. The topic for the first talk is ‘Complexity and MBSE’ and will be presented by Jon Holt and Simon Perry
• 1100 – 1145 – the Model-Based Social Event, where we will be having a general informal chat about all matters MBSE. We will field questions from attendees and do our best to address them. The conveners will be Jon Holt and Simon Perry. Parental discretion is advised.

We will be running these using Microsoft Teams, so fingers crossed everybody!

We will post the URL to join the talk on Thursday morning on LinkedIn.

If you would like to get involved in the MB Social Event, or if you have any other queries, drop us an email at
