Ask a program director how they actually run a portfolio review and you get a version of the same answer. The tool says amber. Beside it they keep a spreadsheet listing which workstreams are late, by how many days, and who owes the next thing — and when the steering committee asks how the program is going, that is what they read from. The amber never comes up.
The calculation may be working exactly as designed. The problem is that a blended result rarely answers the next question: what changed, and what should the team do about it?
Here is the thesis: a blended health score compresses distinct facts into a verdict, making the route back to each underlying signal harder to follow. All five formulas below are published by the vendors themselves.
Five products, five different things called “health”
Sciforma computes a Global Score out of 100 as a weighted average of Time, Cost and Quality, where the Quality component is itself derived from planning problems, resource problems, transaction problems, status reports, work items and risk-completion ratios.3 It is the purest blend on the market. A score of 61 means the weighted average of those inputs came to 61; the contributing signals still need to be reviewed separately.
Broadcom Clarity does not compute from data at all. A project manager picks a status for schedule, for scope, and for cost and effort. Each choice is scored 10, 20 or 30. The overall gauge is the sum: green below 40, yellow from 40 to 89, red at 90 or above.2 The arithmetic is deterministic and the inputs are opinions, which makes the output a very precise representation of three manually selected positions.
Celoxis goes the other way and computes RAG automatically every day, extrapolating a projected finish date and a projected cost from current progress.10 This is the most defensible of the five — right up to the per-project setting, in the product’s own documentation, called “Always assume this project is on time and budget”, which forces the indicator to On Track regardless of the data.
Jira Align tracks five dimensions of health — budget, people, quality, risk and issues, and schedule — each set by hand. Atlassian’s own guide notes that no history is kept, describing it as “a point in time view”, and observes that practitioners work around this by typing the date into the reason field.5 A health indicator with no history cannot answer when a project turned, which is the only question anyone asks a health indicator after the fact.
ServiceNow SPM now predicts RAG with AI, with admin-tunable calculation logic — available to customers holding the Now Assist and SPM Pro Plus licenses.4 The prediction may well be good. It is also a per-seat upsell on the answer to “how is this going”.
The case for a single summary
Executives need a concise summary. Reading eleven workstreams is not practical in every review, and a color can focus attention in a long presentation. The challenge is preserving the route back to the facts.
But notice what the summary costs. To average schedule against cost, you must decide how many days of delay equal how many dollars of overrun. Every one of these products makes that decision for you and none of them shows you the exchange rate. When the amber turns red, the first question in the room is always the same — why — and the score cannot answer it without returning to the underlying schedule, cost, risk, and quality records.
Wellingtone’s annual survey of PMO practice keeps finding the same thing from the other end: organizations struggle to trust the project data they hold.57 The issue is not computation. It is whether the result can be explained in a meeting.
A clearer alternative
BoardWalk keeps the underlying measures visible. A portfolio reads as counts that keep their denominators: 119 requirements mapped of 119, 98 resolved of 119, 0 verified of 119. Each result can be traced directly to the records behind it.
The cost is real and worth naming. A count with a denominator does not fit in a status column, and there is no single cell to paste into an executive pack. Our answer is that the sentence you would have to write instead — zero of a hundred and nineteen requirements have been verified by a named person — is the sentence the meeting was going to arrive at anyway, twenty minutes later, after somebody asked what amber meant.
The spreadsheet beside the dashboard often contains the details that leaders need: the underlying facts, their owners, and the next decision. BoardWalk makes that working record part of the portfolio view.
