Ask the executive sponsor of a major program for its current state and you will usually get a color. The workstreams are green, one is amber, nothing is red. It feels like an answer. It rarely is.
A RAG status is a summary of sentiment. It compresses a complex program into a single reassuring signal, and in doing so it discards exactly the information a sponsor needs. It tells you how the program looks to the person assigning the color — filtered through their optimism, their incentives, and the pressure they are under to keep things green. What it does not tell you is whether the program is actually on course.
What an assessment does instead
An assessment replaces sentiment with evidence. Instead of one color, it produces a structured reading across the dimensions that determine program health — strategic alignment, governance and decision rights, delivery integrity, vendor and stakeholder coordination, and executive visibility. Each is scored against what can be demonstrated, not what is felt. The result is not a reassurance; it is a diagnosis.
The distinction matters most precisely when a program is drifting. Drift is a visibility problem before it is anything else, and RAG reporting is where visibility goes to hide: the colors stay green while the underlying condition erodes, because the color reflects the reporter's confidence rather than the program's reality. By the time the status finally turns amber, months of correctable drift have already compounded.
The practical test
The test is simple. Ask not what color the program is, but what the assessment across those five dimensions would show — and whether anyone can answer with evidence rather than instinct. If the honest answer is that no one knows, the RAG status was never telling you what you thought it was.
