Two Teams, One Organisation, Two Completely Different Business Cases

It is not unusual to find two business cases inside the same organisation, prepared for similar investments, that look almost nothing alike. The financial assumptions are framed differently. The economic analysis sits in a different place. The strategic case is either expansive or compressed depending on who held the pen. Reviewers, who often see both, end up correcting structure before they can evaluate substance.

This inconsistency is rarely the result of poor work. It reflects the fact that business case development still depends heavily on individual interpretation. Each author brings their own habits, their own template, and their own reading of the guidance. The thinking may be strong in both documents, but the surface-level variation makes them hard to compare and slow to approve.

The cost of this falls on governance. When reviewers have to translate between formats, scrutiny becomes less precise. Approval timelines stretch, and feedback drifts toward presentation rather than the assumptions that actually matter. Over time, the variation itself becomes a source of risk.

Consistency does not require rigid uniformity. It requires a shared structural foundation that the thinking can sit on top of. Business Case Guru provides that foundation by embedding Five Case Model discipline directly into the drafting process, so cases across an organisation share a common architecture without sacrificing the substance that distinguishes them.
