What Business Case Guru does
Expert guidance through every strategic decision.
Business Case Guru (BCG) is a software application that helps users write business cases—documents that appraise the case for investment—following HM Treasury's Five Case Model.
Users input project information and interact with the BCG application, making strategic decisions as they are guided through the preparation of a business case.
BCG was founded by business case experts Stefan Sanchez and Fiona Waters, who bring more than 55 years of combined experience in business-case preparation and review, business-case training and investment appraisal.
BCG aligns with government and institutional requirements, ensuring every case is compliant, clear and fit for purpose. The software is compliant with UK public-sector standards, and customer data is not shared with third parties or used for AI training.
