Economic Value
With a job market continuously evolving, many businesses are not interested in having an executive at the bottom with a huge salary. This will not provide much value as the company is paying more for less. Case in point is with a CFO at full-time and making a yearly salary of $550,000 and temporary fractional executives will be determined by the job type and amount of time needed.
A company that is just getting started are perfect examples of a company looking for experience but do not have the financial means to have them onboard longer than temporarily.
