SCARECROW CONSULTANTS LIMITED

What SCARECROW CONSULTANTS LIMITED does

Scarecrow Consultants Limited is a UK-incorporated private limited company founded in August 2014 by Prof Jon Holt and Simon Perry as a tool-independent Model-Based Systems Engineering (MBSE) consultancy. The firm delivers MBSE advisory, training, mentoring, and competency assessment services to organisations implementing or scaling MBSE practices, with documented engagement in defence, space and nuclear fusion, and automotive sectors. The team is small — approximately 5–7 core members — comprising the two founder-directors, Director Jessica Korzeniowska (promoted March 2026), and Associate Consultants Stuart Jobbins and Mike Brownsword.

The service portfolio spans three pillars aligned to the firm's People, Process, and Tools framework: a structured public and in-house training catalogue (MBSE 1-Day, MBSE 3-Day, SysML, Cameo, Enterprise Architect, Architectural Frameworks, Model-Based Requirements Engineering, Agile SE, Risk/Safety/Security, Soft Skills, TeamStorming, MBSE Leadership, and the narrative-based Adventures in Systems Engineering course); a consulting practice covering MBSE assessments, ISO 15288 assessments, tool evaluation and selection, tool implementation for bespoke processes, mentoring, train-the-trainer, and proprietary methodologies (RAVEnS, Trinity Approach, TeamStorming, Interface Pattern); and a publications programme that has produced 18 books on MBSE and systems engineering through IET, IfSE UK, and Packt Publishing. The firm also maintains the Scarecrow Knowledge Base (KnoB), a free client-only resource of enabling patterns, base models, and tool guides.

Revenue is generated through professional services fees (direct enterprise consultancy, mentoring, and competency assessment), course fees for public training, royalties on publications, and channel-based delivery via partnerships with the IET Academy, IfSE UK Endorsed Training Provider scheme, High Tech Institute (Netherlands), SE-Training GmbH (Zurich), and Dassault Systèmes. The firm is founder-owned with no external investment, operates from Birmingham, and holds JOSCAR and Cyber Essentials certifications alongside its INCOSE UK Endorsed Training Provider status. No financial figures have been disclosed.

Scale indicators4 records

Recent moves7 records

Expansion highlights6 records

Direct peers

• SE-Training GmbH: Zurich-based systems engineering training and consulting firm that delivers MBSE and complexity-focused courses. Directly comparable to Scarecrow in Europe-based MBSE/SysML training and the founders are known collaborators via the Conquering Complexity event.
• High Tech Institute: Netherlands-based training provider delivering systems engineering and MBSE courses, including Scarecrow's own curriculum. Operates in the same niche of public and in-house MBSE training for engineering professionals.

Broad incumbents

• Frazer-Nash Consultancy: UK-based engineering consultancy providing systems engineering, safety, and assurance services across defence, transport, and energy. Comparable in serving UK defence/aerospace clients with systems engineering expertise, but operates at much larger scale and broader scope.
• IBM Engineering (formerly Rational): Large incumbent in systems engineering software and services, including the Rhapsody MBSE tool and consulting. Overlaps with Scarecrow in serving enterprises adopting model-based approaches, but as part of a much broader ALM/PLM portfolio.
• Dassault Systèmes (CATIA Magic): Major PLM vendor whose CATIA Magic (formerly No Magic Cameo) is a leading MBSE tool, with embedded training and services. Comparable because Scarecrow delivers Cameo training in partnership with Dassault, but Dassault is a tool-anchored incumbent rather than a pure consultancy.
• Mott MacDonald: Global engineering consultancy with systems engineering capability across transport, energy, and water. Comparable in providing systems engineering consulting to UK enterprise and infrastructure clients, but at much larger scale and broader scope.
• AtkinsRéalis (SNC-Lavalin): Large engineering consultancy with a systems engineering practice serving aerospace, defence, rail, and nuclear clients. Comparable in offering systems engineering advisory in the same verticals, but as part of a much larger multidisciplinary services portfolio.

Emerging players

• Vitech Corporation: US-based MBSE tooling vendor (GENESYS) that also offers implementation services and training. Comparable because it sells both MBSE tools and advisory/training services to systems engineering organisations, though it is tool-anchored rather than tool-independent.
• Sparx Systems: Vendor of Enterprise Architect, a widely used MBSE/modelling tool, and a partner for Scarecrow's EA training courses. Comparable in the MBSE tooling and training ecosystem, though vendor rather than consultancy.

Others

• INCOSE UK / IfSE UK (Institute for Systems Engineering): UK professional body for systems engineering that endorses training providers and sets competency frameworks. Comparable as the standards-setting and community backbone around which Scarecrow builds its training and competency assessment offerings.
