Reasonable skill and care vs fit for purpose

Reasonable skill and care and fit for purpose are two different legal and professional standards in engineering management that define how a project's risk, performance, and liability are shared. Reasonable skill and care means acting like a normal, competent engineer, while fit for purpose means guaranteeing a specific final result. 

Reasonable Skill and Care
  • Definition: You must do your work using the level of knowledge, effort, and judgment expected of a regular, qualified engineer in that field. 
  • Proof of Fault: To claim a mistake was made, the client must prove you were negligent and acted below normal professional standards. 
  • Outcome Guarantee: There is no promise that the final design will be completely flawless or solve every problem, as long as you did the work correctly. 
  • Insurance: This standard is normally covered by standard Professional Indemnity Insurance (PII). 
Fit for Purpose
  • Definition: You guarantee that the final engineering work or product will actually work for the specific goal the client stated. 
  • Proof of Fault: This is a strict liability rule. If the system does not work for its purpose, you are responsible even if you made no mistakes and followed all rules. 
  • Outcome Guarantee: Absolute guarantee of a specific performance result or output (such as a plant producing a set amount of power). 
  • Insurance: Harder to insure, as many professional insurance policies exclude unbacked performance guarantees or strict fitness warranties.
