If every deviation generates a new plan, planning becomes permanent motion. If the plan stays authoritative after a material change, the mine executes a reference that no longer protects the outcome.
The result is not more replanning. It is selective replanning with operational authority.
This changes planning from a document-production cycle into a decision mechanism connected to the people and systems acting on it.
Local disturbances can remain local, while material exceptions trigger coordinated review across mine, stockpiles and processing.
Stability is preserved where the original commitment still works, avoiding planning churn when the reference remains valid.
The operation can deliberately reopen what no longer works, with selective replanning backed by clear operational authority.
How NTT DATA helps
Make visible which haul routes, ore sources, stockpiles, asset availabilities and process requirements support each material commitment.

Identify the operational conditions that should merely be managed locally and those that can invalidate a chainlevel assumption.

Connect the new condition with downstream consequences so planners and operators can compare maintaining, correcting or reopening the commitment.

Clarify who must participate, who can modify which commitment and when escalation is required.

Use event integration, planning and dispatch interfaces and workflow so the revised commitment reaches the people and systems acting on it.

Capture the condition, decision, physical response and result so recurring exceptions can progressively become easier to handle.


The operation needs an explicit path by which a material exception can trigger a decision to maintain, correct or reopen a commitment. A good plan and a good exception mechanism solve different problems.
Planning remains valuable because it creates a reference against which change can be recognized.
Planning creates a reference against which change can be recognized: ore sources, stockpiles, crusher feed and plant commitments.
Integration begins when the operation can decide what to do when that reference stops being sufficient during the shift.
The operation knows which conditions are managed locally and which can invalidate a chain-level assumption behind the plan.
The mine knows when the existing plan should keep its authority, and when it has earned the right to change it with clear authority.
Explore how an explicit exception mechanism can keep mine plans stable while reopening only what no longer protects the outcome.
