    Avoid assuming automation will reduce rework when room and availability data are incomplete, because CELCAT output quality drops in that condition and complex exception handling increases iteration time.

  • Overloading what-if planning with constraints that are expensive to model

    Plan for what-if depth limits when input structure constrains scenario exploration, because RPI Schedule Manager restricts what-if scenario planning compared with solver-first tools. Also prepare for advanced constraint sets to require careful setup in tools like Schedule25 and Coursedog Scheduling.

  • Treating all what-if workflows as equivalent governance for room assignment

    Use 25Live when room assignment governance and operational scenario planning are central, because it includes what-if scenario planning tied to structured room and resource constraints.
