Context · Before AI

Don’t train on everything. Give the decision context.

Most AI failures in operations are context failures: the model was right about the question it was asked, and wrong about the situation it was in.

Short answer

Decision context is the specific data, business rules, history, constraints and human knowledge that one decision needs — not all the data an organization owns. Good decision intelligence assembles that context per decision, scores whether it is complete and fresh, and asks for what is missing instead of guessing.

Why context beats more data

Throwing every table and document at a model increases cost and noise without guaranteeing the one fact that matters is present. Decisions fail when a critical input is missing, stale or misread — the supplier’s real capacity, today’s crew roster, the patient’s latest lab, the robot’s last calibration. Context engineering starts from the decision and works backwards to the inputs it requires.

The four layers of context

DataTransactions, sensor readings, schedules, balances — the current state of the world.
RulesPolicies, contracts, regulations, safety limits, approval thresholds.
HistoryPast decisions, their outcomes, failure modes, seasonality.
Human knowledgeOperator notes, tribal knowledge, expert overrides and their reasons.
Context is more than data: rules, history and human knowledge change which option is right.

Context health: a score every decision should carry

Before recommending anything, a decision intelligence system should report context health — how complete and fresh the required inputs are.

InputSourceFreshness requiredStatus
Open ordersERP< 1 hour✓ 12 minutes old
Line scheduleMES< 1 shift✓ current
InventoryIoT / WMS< 15 minutes✓ live
Procurement policyPolicy storeCurrent version✓ v4.2
Supplier B capacitySupplier portal< 24 hours✗ missing — requested

With one critical input missing, context health might read 61%. The right behavior is to request the missing input and hold or lower confidence — not to produce a confident answer anyway.

What to do when context is missing

  1. AskRequest the missing input from the system or person who owns it, with a deadline.
  2. DegradeRecommend a conservative, reversible option and say why.
  3. EscalateHand the decision to a human with the gap highlighted.
  4. AbstainIf the decision is out of the domain the system knows, say so and do nothing.

Example: the same decision, two contexts

Without decision contextWith decision context
SignalSupplier 03 is four days lateSupplier 03 is four days late
KnownOpen ordersOrders, schedule, inventory, policy, lead-time history
MissingUnknown — not trackedSupplier B capacity — requested with a 2-hour deadline
RecommendationMove to Supplier B (confident)Hold at 61% context health; move to Supplier B once capacity confirms
ResultSupplier B can’t deliver; orders missCapacity confirmed; orders ship Thursday

Context for LLMs and agents

For large language models and agents, decision context is delivered through retrieval, tool calls and structured state rather than training. The same rules apply: retrieve for the decision, cite what was used, detect contradictions between sources, and never let an agent act on context it could not verify. See decision safety.

Key takeaways
  • Start from the decision and work back to the inputs it needs.
  • Context includes rules, history and human knowledge — not just data.
  • Score context health and make missing inputs visible.
  • Missing context should change behavior: ask, degrade, escalate or abstain.

Frequently asked questions

What is decision context?
The specific data, rules, history, constraints and human knowledge a particular decision needs, with each input’s freshness and completeness known.
Why not just give AI all our data?
More data increases cost and noise and still does not guarantee the critical input is present and current. Decision-specific context is cheaper, safer and easier to audit.
What is context health?
A score showing how complete and fresh the inputs required by a decision are, so the system and humans know how much to trust a recommendation.
How does context engineering relate to RAG?
Retrieval-augmented generation is one way to deliver context to a language model. Context engineering decides what to retrieve for a given decision and how to handle gaps.
