NewBusiness Cases that Get Results: A Civil Service Perspective

An effective business case approach at its core aims to do two things: 

  1. Provides a structured, evidence-based framework for decision-making framework that supports diverse stakeholders.  

  2. Offering reliable way to document decisions, stakeholder perspectives, and build a valuable evidence base for future reference. 


In this one-hour, complimentary webinar, Mark Williams will guide participants through these fundamental goals and examine how effectively UK public services are applying them amid increasing complexity, change, and fiscal pressure. 

Business Cases That Get Results: A Civil Service Perspective

This session will particularly focus on: 

  • The purpose and importance of business cases in the public sector. 

  • Key stages in business case development, including the Five Case Model (Strategic, Economic, Financial, Commercial, and Management case assessments). 

  • Real-world insights through practical case studies and lessons from over 30 years of public sector experience. 

  • Practical tips for navigating complex decision-making and stakeholder management. 

Our discussion will be grounded in HM Treasury's best practice guidance, emphasising its principles-based approach that allows for flexible application across various public sector decisions.
