This is the most boring entry in the glossary and one of the most expensive to get wrong.
Why it matters
A route is built from coordinates, not from addresses. An address that resolves to the centre of a postcode rather than to the property can sit a mile or more from where the technician actually goes. The planner then builds a sensible route around a location that does not exist, and the technician absorbs the difference every visit.
In rural areas and new developments this is common rather than rare.
How you notice it slipping
Technicians report that the sequence makes no sense for specific accounts — always the same ones. Drive times for certain stops are consistently worse than planned. New developments and rural addresses show up clustered at an implausible single point on the map.
What to do
Review the accounts with the largest gap between planned and actual drive time; bad coordinates sit at the top of that list. Fix the point rather than the address text, and give the field a way to report one — the technician standing in the driveway is the best source of truth you will ever have.
