Using an Exception Log in Remote Dental CAD

An exception log helps a lab separate an incomplete input, a preference change and a design correction. It is a practical tool for resolving work, not a scorecard that automatically assigns blame.

Describe the observable issue

Record the internal case identifier, stage, current version and issue category. State what is missing, conflicting or different from the agreed brief. Avoid recording a presumed cause as fact when the team has not investigated it.

Assign the right decision owner

A component-identification question, clinical clarification and file-format issue may need different people. Record who can resolve the issue and what the designer needs before proceeding. A deadline without a decision owner does not make an incomplete record usable.

Identify dependent work

State which unit, arch, output or milestone is affected. Some clarification allows other work to continue; other ambiguity affects the entire design. The responsible teams should decide the impact rather than applying an automatic proceed-or-stop rule to every case.

Close the issue with a versioned decision

Record the clarified instruction or replacement record, the decision date and whether scope or timing changes. Link the resolution to the design version. A chat message that says fixed is less useful than a note identifying which input and output now apply.

Review patterns without inventing statistics

At the end of a pilot, count actual issue categories and examine recurring clarification needs. Use consistent definitions and avoid presenting a small sample as a clinical outcome study. Improve the preference packet or submission route based on evidence from your own cases.

Classify CAD Issues Without Confusing Observation and Cause

Keep symptom, category and cause separate

Write the observation first, such as an absent file, a conflicting reference or an exact warning. Choose a provisional category that helps route it. Record the cause as unknown until evidence supports a conclusion; do not make the category itself a finding of fault.

A production warning may arise from a method configuration, permission or another issue. The distinct 3Shape save-permission and local-library-production articles illustrate why similar endpoints need different diagnostic evidence. An output-generation failure alone does not prove a design error.

Use categories that point to a next decision

This original taxonomy is a starting point for an internal issue log. Keep the category set small enough to use consistently and permit reclassification when new evidence arrives.

Use categories that point to a next decision — original worksheet
Check	Evidence or next decision
Input/provenance	Required record absent, role unknown or source revision unclear; ask responsible sender.
Instruction/reference	Current prescription, governing reference or numbering needs confirmation.
Environment/permission	Exact product/version/license/library route needs administrator or supplier evidence.
Design versus brief	Observed difference against a verified current instruction; qualified review required.
Delivery/revision	Wrong output role, stale file or superseded package; reconcile manifest.
Cause unresolved	Preserve the observation and next question instead of guessing.

Close and reclassify with an evidence trail

Hypothetical example: an item begins as “delivery file missing.” Investigation finds an exact provider-permission warning. Keep the original observation and reclassify the resolved cause with the supplier decision. Do not erase the receiving symptom or retrospectively label it a designer error.

When reviewing patterns, state whether you counted issue events, affected cases or unresolved items, and how reclassifications are handled. Several observations in one case are not several independent failed cases. Keep changed inputs, late preferences and verified corrections distinguishable.

Validation and limits

Louie validation pending — unverified locally. Louie must validate the taxonomy, category definitions and closure criteria against actual examples. Exact software causes need applicable vendor evidence and local reproduction; the categories are original operations guidance, not clinical diagnoses or a ranking of designer quality.

The worksheet is blank and contains no patient data or executable settings. Examples are hypothetical, not tested Pristine cases. Actual prescriptions, applicable manufacturer instructions and responsible approvals govern design and production.
