5 Hvorfor i Erhvervslivet

Hvad er 5 hvorfor

af Nathanael Okhuysen

Når noget går galt, især i en stor organisation, kan der være et instinkt til at pege fingre og skifte skyld. Dette er nok ikke den bedste måde at forhindre, at problemet opstår i fremtiden. Sakichi Toyoda, grundlæggeren af ​​Toyota Motor Company, udviklede "5 Whys" -processen, en form for grundårsagsanalyse, til at identificere og løse problemer, der opstod i virksomheden. Det er siden blevet bredt vedtaget som en del af Lean Manufacturing, Kaizen og Six Sigma-metoden.
