Drafts leave room for decisions
Rush orders and breakdowns require planners to compare alternatives. Drafts hold that exploration and allow candidate adoption and adjustments. Each change should expose its impact without immediately replacing the floor’s current plan.
Execution versions provide a stable reference
Shop-floor reports need an explicit execution version. Confirm the release with the receiving system before switching the plan, so everyone can follow the same reference.
Snapshots explain changes
Release snapshots preserve the basis of past plans and help review order and resource changes. Undoing a draft edit should not undo progress reports or equipment state: those are facts that already happened.
Feedback improves the next plan
Starts, completions, and remaining processing time change the next solving input. In-progress tasks must respect their actual equipment and remaining work, rather than being moved simply to improve a planning metric.
