Methodology: how every figure is calculated.
Each figure in Propility is built from the same few ingredients: what condition an asset is in, how long it is likely to last, how likely it is to fail and what that failure would cost.
Costs come from published industry rates alongside your own records. Nothing is hidden: every number opens to show its inputs and assumptions, and forecasts are checked against what actually happened so accuracy can be seen.
- Condition and remaining lifeTaken from surveys and records, with gaps in the evidence flagged rather than guessed.
- Likelihood and cost of failureWhat happens if the asset fails, from repair bills to closure and lost income.
- Rates and assumptionsPublished rates and your own costs, with every assumption shown beside the figure.
- Checked against outcomesForecasts are compared with what actually happened, so accuracy can be seen.
