The ACORN test is an easy to remember way to evaluate the charter of an improvement project.
A Accomplishment. Does the goal actually focus on results?
C Control. Does the team have control of what is needed to implement and complete the project?
O Objective. Is the objective the ultimate achievement of the project or is it actually a sub goal?
R Reconciliation. No other improvement teams have the same goals as your team and so there re no conflicts.
N Numbers. To know if the goal has been achieved can it be measured?
