Designing skill-set matching
When using work queues with skill sets, design the skill set levels to apply evenly across tasks in the
work queue. For example, if there are 2 skill levels defined in the skill set for a work queue with 100
tasks, design the skill levels so they result in approximately 50 tasks being uniformly distributed.
Unbalanced skill set filtering can create bottlenecks and sluggish Get Next Task performance in the
work queues of those individuals with the less discriminatory skill values.
Skill set matching works like a precondition (Avoiding unnecessary preconditions, page 50) in that
TaskSpace sequentially evaluates each row in the task list against user competency. Furthermore, skill
set matching requires evaluation of the entire task list. For large task lists (10,000 items, for example),
evaluating an entire task list can have a significant performance impact.
Establish a baseline performance metric for your form before adding skill sets. Assess the
performance impact of adding skill set matching against the baseline to determine whether the value
offered by skill set processing is worth the performance cost.
