Evaluating a result
Look at the business question, supporting evidence, unresolved conditions, and the work you still had to arrange.
Start with the decision you need to make
Does the result answer the business question you set out to address? Do the important requirements still hold together? A calculation can be correct and a document can be polished without giving you enough to make the intended decision.
Look at the evidence for this result
Review the sources and method, the version that was checked, and the conditions still unresolved. A previous success or a large volume of output does not establish that the current result is ready to use.
Consider the work it took off your hands
E2C is intended to take on more of the continuing organization. To assess its contribution, ask whether you still had to reconstruct requirements, arrange each revision, or reconnect the steps yourself. Consider both the immediate result and the system left for later work. The benefit needs to show up in practice.
Keep approval separate
A process finishing is not the same as a result being suitable for use. Revisit the basis for a decision when sources, methods, permissions, or conditions change. Professional approval, experiments, safety review, and certification cannot be replaced by a completion message.
