The KOE Model: Knowledge, Observation, Evidence

Evalium uses a simple framework for verifying high-stakes work: the KOE Model.

While many systems only record a simple "pass" or "fail," Evalium recognizes that true defensibility often requires a combination of what someone knows, what was observed, and what physical evidence exists.

1. Knowledge (K)​

What do they know?

This covers theoretical understanding and baseline acknowledgement.

  • Examples: Safety declarations, knowledge-checks, or short responses.
  • Verification: Usually automatically handled by the system.

2. Observation (O)​

What was seen?

This is the record of a real-world action. An observer rates a task against a standardized rubric or set of criteria.

  • Examples: A site inspection, a manager observing a technical procedure, or a quality check.
  • Verification: Based on the professional judgment of an evaluator.

3. Evidence (E)​

Can they prove it?

Evidence is the objective proof that substantiates a record. It is a supporting artifact that exists independently of the person performing the task.

  • Examples: A photo of a completed installation, a signed permit, or a video demonstration.
  • Verification: Reviewed and ratified to ensure it meets your organization's policy.

Verification Strength​

By combining these three elements, you can set the Verification Strength for any workflow.

A process that only requires "Knowledge" is fast but less defensible. By adding "Observation" and "Verified Evidence," you create a record that can withstand professional scrutiny and audit. Evalium helps you find the right balance for every workflow.
