Impact and Health scores

How Bonzaii scores features, solutions and products, without RICE or ICE scores.

Bonzaii uses two kinds of score: Impact (how much value for the effort) and Health (how well something is doing). There is no RICE or ICE score.

Every score input is rated 1 to 5.

Impact score — features (Feature impact)

(User impact × User reach × Business impact) ÷ (Delivery effort × Maintenance effort)

A missing maintenance effort counts as 1. If impact, reach, business impact or delivery effort is missing, there's no score. Scores range from 0.04 to 125.

Impact score — solutions (Solution impact)

(User impact × User reach × Business impact × Confidence) ÷ Delivery effort

All five inputs are needed. Scores range from 0.2 to 625.

Feature impact vs Solution impact

Where features and solutions appear together (for example in Planning), their scores are labelled Feature impact and Solution impact. They are not on the same scale:

  • Feature impact rates something that already exists or is planned as a whole, and includes the maintenance effort of keeping it. It ranges from 0.04 to 125.
  • Solution impact rates one piece of work you might build, and includes your confidence that it will work. It ranges from 0.2 to 625.

So a solution scoring 50 isn't "worth less" than a feature scoring 60. Compare them by their category (Exceptional to Minimal), which uses each one's own range.

Linked research marked Contradicts appears as a study count beside Feature impact. Under Solution confidence, the count suggests considering lower confidence. These warnings never change your score inputs automatically.

Impact category

The score is placed on a log scale between the lowest and highest possible score, then labelled Exceptional, High, Medium, Low or Minimal. Products use the feature range; releases use the solution range.

Example: a solution with impact 4, reach 4, business impact 3, confidence 4 and effort 2 scores 4 × 4 × 3 × 4 ÷ 2 = 96, which is High.

Product Impact

The average of each input over the product's live features that have scoring on, put through the feature formula. It's not the average of the features' scores.

Feature Health (0–100)

Starts at 100. Minus 20 for each open critical problem linked to the feature, minus 10 for each open high-severity one. Minus 25 if the feature hasn't been updated for 90 days (or minus 10 after 30 days). It's calculated once a day and shown in the feature's Scoring trend.

Product Health (0–100)

An even mix of four parts: features (Product Impact), delivery pace, open problems, and key results completed. Above 80 is Excellent, above 60 Good, above 40 Needs attention, otherwise Critical.
