A Robust Foundation for your Business Cases

5CS ensures your business cases meet best-practice standards.

5CS is based on the Five Case Model, which sets the standard for best-practice business case development. It is used by the UK and Welsh governments and recommended by HM Treasury.

Built around the UK Treasury’s Green Book and the Five Case Model, 5CS ensures alignment with best-practice standards and facilitates faster, more accurate submissions, better collaboration, and transparency throughout the development process. This helps reduce approval delays and supports stronger decision-making.
