TPP/TCP Quantitative Gap Calculator
Normalize minimum, ideal, and observed values by target direction to calculate per-characteristic gaps and shortfalls.
TPP/TCP quantitative gap
A signed gap is positive beyond the boundary in the desired direction and negative when short. Position is 0% at minimum and 100% at ideal and is not clamped.
Enter minimum, ideal, and observed values for each quantitative characteristic.
This tool calculates numeric gaps for each characteristic only. It does not combine unlike units or importance into a score, weight, readiness status, Go/No-Go decision, or regulatory conclusion. Manage definitions, data maturity, uncertainty/CIs, and evidence sources separately in the TPP/TCP table.
Basis: WHO product-profile structure with minimally acceptable and preferred/ideal characteristics, expressed here as direction-normalized arithmetic gaps.
Tool Guide
Definition
TPP/TCP Quantitative Gap Calculator — Direction-normalizes each quantitative characteristic’s minimum/acceptable, preferred/ideal, and observed/current values as higher- or lower-is-better, then calculates signed gaps, shortfalls, and position from minimum to ideal.
Purpose
(1) Organize unlike-unit TPP/TCP characteristics into direction-consistent gap columns, (2) separate shortfall to minimum from shortfall to ideal, (3) calculate an unclamped position with 0%=minimum and 100%=ideal, and (4) copy a quantitative comparison table.
How to Use
① Enter characteristic name/unit plus minimum, ideal, and observed values. ② Select whether higher or lower is better. ③ Read signed gaps as positive beyond a boundary in the desired direction and negative when short. ④ Record characteristic-specific uncertainty/CIs and evidence sources in the source TPP/TCP. No aggregate score or readiness decision is produced.
Examples
Example) Sensitivity minimum=50%, ideal=80%, observed=65% gives minimum gap +15 points, ideal gap −15 points, and position 50%. For lower-is-better time-to-result with minimum=10 min, ideal=4 min, observed=7 min, normalization gives +3, −3, and 50%. This is not a readiness decision.
