A full schedule is not the same as a workable day. Targeted buffer absorbs known uncertainty without leaving capacity arbitrarily empty.
Make uncertainty local
Traffic, parking, complex care, handoff and uncertain finish times each follow a different pattern. Use actual delivery times and team knowledge to locate where delay starts and how widely it varies. A general uplift across the day hides that information: stable visits receive too much room while the genuinely volatile transition remains too tight.
Put buffer where the route can recover
Buffer after the final visit does not protect a medication moment in the middle of the day. Put it before a hard deadline, after a cluster with variable duration or where work can responsibly move between people. Keep breaks and handoff visible separately. Treating them as free capacity removes the very recovery room the plan relies on when the day becomes pressured.
Learn from use and shortage
Measure how often buffer is used, how much remains and which delay still reaches later visits. Consistently unused room can shrink; persistent shortage needs a better service duration, route or rule. Discuss aggregate patterns with planners and delivery teams. Never turn buffer use into an individual productivity measure because that creates pressure to hide necessary margin.
