The learning and action loop—check-plan-do. Derived from Deming, a simple, standard three-step process called ‘check–plan–do’, is used generate feedback systemically and incorporate it into the organization: ‘Check’ asks:
. What is the purpose of this system? . Demand—what is the nature of customer demand on the system? . Capability—what is the system predictably achieving against the demand? . Flow—how does the work move through the system? . System conditions—why does the system behave in the way it does?
‘Plan’ asks:
. What needs to change to improve performance against purpose? . What action could be taken and what would be the consequences of taking it? . What are the measures against which action should be taken (to ensure learning)?
‘Do’ says:
. Take the planned action; . And start again at check.
