The Need for Work in Progress (WIP) Management
One of the key challenges facing pathology laboratories is peak arrival patterns caused by logistics associated with
outpatient work. These peak arrivals result in capacity constraints especially with respect to equipment and FTE’s
which is usually designed for average workloads within normal operating hours.
It becomes necessary to manage the workflow by separating work with a lower priorit from work with a higher
priority. The lower priority work is placed into the Clever Trolley and is released according to a First In First Out (FIFO)
                               mes                                                                            cost
rule as analyser capacity becomes available according to user defined parameters. This allows for more co effective
processing through the optimal utilisation of available resources.
