ERP decision records: bu ne anlama geliyor
Ask where decisions are recorded and you will be pointed at the ERP. It holds the purchase order, the production order, the price change. That is the outcome, not the decision.
The decision was: order 400 rather than 250, from this supplier rather than that one, accepting a longer lead time because the price was better and stock cover allowed it. None of that survives.
Why the gap matters
Without the reasoning, you cannot tell a good decision that turned out badly from a bad decision that got lucky. Over a year, an organisation with thousands of such decisions learns nothing from any of them.
What a decision record needs
A stable identifier, the inputs with their values at the time, the alternatives considered, the constraint that bound the choice, the person or agent responsible, and the outcome once known.
This is not a large amount of data. It is simply data nobody currently captures, because no system was designed to hold it — which is what a decision layer is actually for.
What the ERP is genuinely for
Recording commitments. A purchase order is a contract; a production order is an instruction; a price change is a fact about the world. The ERP holds these accurately and that is its job.
The mistake is inferring that because it holds the outcome, it holds the decision. Those are different objects with different lifetimes — the decision existed before the order, considered things the order does not contain, and remains interesting after the order has been fulfilled and closed.
An ERP asked to hold decisions ends up with them in free-text notes, which is where reasoning goes to become unqueryable.
Good decision, bad outcome
The distinction the record exists to preserve.
A planner orders 250 against a forecast of 240, with lead time stable and no promotion signalled. Demand spikes to 400 because a competitor had a recall. The decision was correct and the outcome was a stockout.
Without a record, the review reaches the only available conclusion: someone under-ordered. The planner learns to over-order. Six months of that costs more than the stockout did.
With a record, the review can see that the inputs did not contain the recall, ask whether they could have, and conclude that this class of event is unforecastable — which is a finding rather than a blame allocation.
The volume is smaller than people expect
A mid-size operation makes perhaps a few thousand consequential decisions a month. Each record is a handful of fields.
That is a small table by any modern standard, and the objection is never really about storage. It is that no existing system owns the object, so recording it requires deciding that decisions are a thing worth having a system of record for.
Where the record has to be written
At the moment of the decision, by whatever made it, in the same transaction. Reconstructed later from the ERP and a warehouse is not equivalent: the inputs will have moved, and a record assembled from current values describes a decision nobody made.
This is the constraint that determines architecture, and it is why a decision layer cannot be an analytics project bolted on afterwards.
What accumulates
After a year, a searchable history of why the organisation did what it did. That supports the audit conversation, but its larger use is internal: which constraints actually bind, which forecasts are trusted and which are routinely overridden, and where the same problem is being solved repeatedly under different names.
None of that is available from an ERP, however complete its transaction history.
