Engineering Trifecta

This may be a useful check when considering development guidelines. Each guideline should lead to one or more factors of the trifecta.

Correctness

Free from error or fault; true or accurate.

Safety

The condition of being protected from harm or other non-desirable outcomes.

Efficiency

Efficiency is the ability to avoid wasting resources in producing a desired result.

Note

Do not confuse with Effectiveness.

This is especially for czech readers where the word efektivita sounds just like effectiveness but carries the meaning of efficiency.
