7. Continuous Representation
 The continuous
representation allows an
organization to select a
group of process areasand
improve processes related
to it.
 Select the order of improvement that best
meets the business objectives of the
organization and mitigate risk areas of the
same.
 Objectively improve organizational process.
 Allow capacity increased visibility achieved
in each individual process area.
