We have employees with competencies:
Pete Welder Carpenter Melissa Carpenter
Assume they both work 40 hours/week, and have not yet been assigned work.
We need to report the availability of these competencies, expressed in hours.
As far as I can see now, we can report this in two ways:
Method A. When someone has multiple competencies, count them both.
Welder 40 hours Carpenter 80 hours
Method B. When someone has multiple competencies, count an equal division of hours for each
Welder 20 hours Carpenter 60 hours
Method A has our preference:
- A good planner will know to plan the least available competency first. If 30 hours of welding is planned, we will be left with 10 welder, 50 carpenter.
- Method B has the disadvantage that the planner thinks he cannot plan the job when 30 hours of welding is required.
However, if we report this we would like to give an estimate of the reliability of the numbers for each competency, i.e. how much are these over-reported?
In my example A, would I say that carpenter is 100% over-reported, or 50%, or maybe another number?
How would I calculate this for large numbers of competencies?
I'm sure we are not the first ones dealing with this, is there a 'usual' way of doing this in planning?
- Would there be an even better method than A or B?
- Optionally, we also have an preference order of competencies (like: use him/her in this order), Pete could be 1. welder 2. carpenter. Does this introduce new options?
