    Time windows

    Preferred time, allowed window, and service properties

    See the difference between preferred time and a Layer 2 window, and between routed field visits, office work, overlap, and double staffing.

    Preferred time remains the target

    Preferred time shows when the source or care plan says the service should ideally start. The allowed time window is the boundary within which a proposal may place the visit. A wider allowed window does not overwrite preferred time.

    Preferred time and the allowed time window are shown separately with frozen Layer 2 scope.
    Preferred time remains while Layer 2 may widen the allowed window with frozen shiftScope and dayScope.

    Layer 2 can widen selected services

    For selected non-time-critical services, Layer 2 can widen the allowed time window. The operation can limit the rule with shiftScope and dayScope, for example to one shift or selected weekdays.

    The same scope is frozen with the candidate and follows solve, campaign, and replay. The rule does not change the source care plan and must not be described as general flexibility for every visit.

    Routing, office work, and overlap are separate properties

    Routed field visits receive travel between stops. Office work has no travel to or from the activity. Overlap is a separate permission for selected routed services, such as cleaning, laundry, or shopping, to happen at the same time as another activity.

    Double staffing instead means that one visit requires several employees. It is not the same as overlap and not the same as office work.

    Routed field visits, office work, and allowed overlap are shown as separate properties.
    Routing, office location, and simultaneity are three separate properties; double staffing is another requirement.

    Visit chains

    When several visits for the same client belong together, they can be planned as a chain. Caire then sees a more accurate work shape than if each row is treated as an independent stop.
