Engineering Estimates
Engineering estimates and calculations
A number is not evidence by itself. The model, assumptions, applicable range and sensitivity of the result must be visible.
Authorial methodology
The methodology was developed by Oleksandr Koretskiy from long-term engineering, project and consulting practice and formalized for systematic analysis of technical, technological and business problems.
01
Estimate structure
Inputs → Formula or model → Units → Assumptions → Range → Sensitivity → Limitations → Validation need.
02
We distinguish
— theoretical estimate;
— order-of-magnitude estimate;
— benchmark;
— engineering calculation;
— scenario;
— sensitivity analysis;
— measured value.
03
Principle
A calculation does not become evidence simply because it contains many decimal places.
