Critical Success Factors (CSFs) are those activities and capabilities that are essential for a company to succeed in its market. CSFs are those few things that absolutely, positively must go right to ensure success for the organization. Because these factors are industry‐ and at times geographically‐specific, they will vary from company to company. These factors relate to what the company needs to do to succeed in a continuous manner, not necessarily what it is currently doing.
Typically referring to process‐related improvement programs, CSFs are the key factors as relayed by stakeholders that are important to the success of the project/program.
