Preparing job scheduling software for the first week
Write your job types with the durations they really take, including the callback that always takes longer than the original visit. Enter each person with their real hours and the skills they actually have, and enter the vans, because two people and one vehicle is one job at a time. Set travel time honestly for the distances you cover — it is the single number that decides whether the afternoon holds. Decide your window widths and say them out loud in the words your customers will hear. Decide what happens when nobody is home. Then run one week with windows before you promise them to everybody.
Work at addresses beyond your control
The work happens at an address you do not control, and some of that is beyond any calendar.
