8. Management takes action only if an activity
occurs out of fixed performance & norms
Performance within standard = stable process
Implementation, e.g.:
◦ Standard of service delivery: 5-10 mins
◦ Actual service delivery A: 6.5 mins
◦ Actual service delivery B: 12 mins (?)
◦ Actual service delivery C: 3 mins (?)
Some CBIS are capable of automatically
adjusting activities to stabilise processes, i.e.
manufacturing lines
