Kingman's formula (org design)
Kingman’s approximation states are equal to
where τ is the mean service time (i.e. μ = 1/τ is the service rate), λ is the mean arrival rate, ρ = λ/μ is the utilization, ca is the coefficient of variation for arrivals (that is the standard deviation of arrival times divided by the mean arrival time) and cs is the coefficient of variation for service times.
Summary:
Working at or close to 100% utilization will slow everything that depends on you to crawl.
Resolution:
Leaders can reduce dependent work using [[ Eisenhower Decision Matrix ]] from Important and drop or delegate work from Non-Important.
