logic of long established processes is usually far from perfect.
The critical path to delivering results is rarely identified
Resources are not planned or prioritised for on-time delivery.
Bottlenecks and significant waiting times are common.
The optimum cycle time is not known.
Following the initial definition of a process the most obvious improvements
are usually made fairly easily.
The process should then be more radically challenged to generate truly
optimised performance and productivity.
The identification of the critical path enables the planning and
prioritisation of resources to be targeted at the fastest possible delivery.
The elimination of waiting
time, bottlenecks and under-used resources can have dramatic effects on
productivity and cycle times.
The entire process becomes more reliable and predictable.
