"I have worked closely with Stefan for over fifteen years, including developing the accredited Five Case Model training programme together, and his knowledge and understanding of the 5CM is genuinely second to none.
He is an outstanding trainer and practitioner who makes complex business case concepts accessible at every level.
The Business Case Guru app is exactly the practical tool the business case community has needed, and I am delighted to support it as a special advisor to the BCG board."
— Joe Flanagan, Author of the Five Case Model
“Fiona brings a rare combination of rigour and pragmatism to business case development. On CoSTAR and Createch Futures for UK Research and Innovation, the Department for Science, Innovation and Technology and the Department for Culture, Media and Sport, she translated complex, uncertain R&D impacts into a clear and defensible economic case — particularly where benefits were difficult to monetise.
Fiona works very dynamically and adaptively to the specific demands of each case and rapidly builds rapport with multiple stakeholders. Just as importantly, she was a pleasure to work with: collaborative, responsive, and able to move teams forward at pace.”
— Laura Partridge, Associate Director, Arts and Humanities Research Council.
Shaping the Standards We Work By
Business Case Guru’s Co-Founder and Chief Executive Stefan Sanchez contributed to the development of the Better Business Cases (BBC) guidance as a UK civil servant, working closely with Dr Joe Flanagan. His focus was on translating HM Treasury Green Book principles into practical, usable guidance that could be applied consistently across government, balancing methodological rigour with real-world delivery constraints.
He also supported the design and rollout of the original accredited Better Business Cases training programme, helping embed the framework across departments. This work focused on building capability and driving consistent, evidence-based business case development aligned to the Five Case Model, ensuring outputs were robust and able to withstand scrutiny.
