These four product names describe one decision made over and over: who goes to this job. Availability is the half everybody models, and it is the easy half. The rest is skill, certification, whether this person has been to this customer before, and whether they are close enough to arrive inside the window somebody promised. Software is useful exactly to the extent that it makes all four visible at once.
Availability is necessary and not sufficient
A board showing who is free will happily send an apprentice to a job requiring a certificate, or send somebody thirty miles past a colleague. Free is the first filter and the least interesting one. The decision the dispatcher actually makes is a ranking among the people who could go, and that ranking needs more facts than a calendar holds.
Certification is a hard constraint, not a preference
Where a certificate is a legal condition of the work, such as the Environmental Protection Agency Section 608 requirement for handling refrigerant, sending the wrong person is not inefficient, it is a job that cannot be done. Holding those records against the technician, visible at the moment of assignment, is the difference between a rule and a hope.
Tracking people, and where it stops being useful
Knowing roughly where a van is helps a dispatcher answer a customer and decide who takes an emergency. Knowing precisely where somebody is at every moment is a different product with a different purpose, and it changes how a team feels about the software. Be clear which of the two you are buying and why.
Continuity is worth more than proximity
Sending the person who was there last time is often better than sending the nearest, because they already know the site, the customer and the fault history. A board that shows previous visits at the point of assignment makes that choice possible; one that does not makes it accidental.
Questions people ask about technician dispatch software
Should technicians see each other schedules?
There are good arguments both ways. What matters is that they see their own day without ringing the office.
Is location tracking necessary?
For answering where are you now, a status is usually enough. Continuous tracking is a bigger decision than a feature toggle.
Can the software rank candidates automatically?
It can shortlist. The last step is a judgement about customers, and dispatchers are better at it than rules are.
