PSD-ENTRY-03 — Find what is wrong when the report is on time

  • Situation: Weekly reports arrive on time, yet the planner must telephone colleagues to recover identifiers before using them.
  • Question: Is the difficulty incomplete information, incompatible identifiers, an unsuitable deadline, or a misleading record?
  • First useful result or blocker: Distinct formulations with an observation that could separate them, or the exact missing fact that prevents stating what is wrong.
  • Start with: PSD.3 to compare the formulations. If the discrepancy is already understood and only a recording correction is needed, make that correction through the responsible practice.
  • Stop or return: Stop when the formulation and available facts suffice for the current question. Open a causal-model question only when different explanations change the next useful action; return to the formulation if a check changes what was actually wrong.

The report-handoff application follows that conditional continuation: causal alternatives can inform a bounded answer, while missing evidence, a recipient’s objection or later observations can change it. A diagnostic check, temporary operational help and research answer different questions and may occur at the same time.
