How do you calculate a product launch readiness score?

Rate the launch failure on severity, occurrence, and detection difficulty, then combine them with a weighting. With severity 8, occurrence 5, and detection 4, the weighted launch readiness risk score is 5.95 — a mid-to-high risk worth a mitigation plan before launch.

What is a good launch readiness risk score?

Lower is safer. On a roughly 1-10 weighted scale, scores under 3 are typically green and ready, 3-6 are watch-list items needing a plan, and above 6 should block or gate the launch. The example 5.95 sits firmly in the watch-list band.

Why use a weighted score instead of multiplying the three numbers?

Classic FMEA multiplies severity x occurrence x detection into an RPN, but RPNs over-react to small rating changes and treat all three factors equally. A weighted blend keeps severity dominant — a catastrophic launch miss matters even when it is unlikely — and keeps the result on an intuitive 1-10 scale.

How is this different from a standard FMEA RPN?

An RPN is the raw product of the three ratings and can swing from 8 to 512. This readiness score is a weighted, normalized blend, so 5.95 is directly comparable to other launch risks without the explosive scaling of an RPN.

What should I do with a score of 5.95?

Treat it as an open risk that needs an owner and a mitigation before the launch gate. Because severity is high at 8, focus on either lowering occurrence through design or process change, or improving detection so the issue cannot reach customers undetected.

Which input should I improve first to lower the score?

Severity is usually baked into the design and hardest to change, so push on detection and occurrence. Improving detection from 4 to a stronger inspection or test is often the fastest way to bring the weighted score down before launch.

Consumer Goods & Durable Products Manufacturing calculator

Product Launch Readiness Calculator

Product Launch Readiness is an FMEA-style risk score that ranks how likely a new consumer product is to stumble at launch and how badly a miss would hurt. It blends three judgments — how severe a launch failure would be, how likely the failure is to occur, and how hard it would be to catch before product ships. Launch managers, NPI engineers, and program leads use it to focus limited pre-launch hours on the risks that actually threaten the date or the brand. Unlike a simple gut check, the weighted score makes risks comparable across features and across products so the launch review can argue about numbers, not opinions.

What this calculator does

Score launch readiness risk for a consumer goods or durable product introduction.
deciding whether a new SKU is ready for pilot build, production release, or retailer launch
It computes a single weighted launch-risk score from severity, occurrence, and detection-difficulty inputs so risks can be ranked.

Formula used

Product launch readiness risk score = weighted score from launch impact, occurrence, and detection difficulty
Use the score to compare launch risks and decide where readiness work is still needed.

Inputs explained

Launch failure severity (impact if it ships wrong):
Likelihood the launch issue occurs:
Difficulty of detecting the issue before launch:

How to use the result

Use it during NPI gate reviews and launch-readiness checks to decide which open issues still need mitigation before go-live.
The score reflects subjective 1-10 ratings; it is only as good as the team's calibration and should guide discussion, not replace engineering judgment.
