How to Evaluate an AI-SOP Project for Production

The purpose of an AI-SOP project is not simply to add a vision model to a workstation. It is to translate critical operating standards into a workflow that can be observed, evaluated, acted upon and traced on the production floor. A sound feasibility study therefore covers imaging, models, installation, workflow logic and system integration.

Define the Production Challenge First

Start by identifying the risk the system is expected to reduce: missing parts, incorrect assembly, operation sequence errors, improper tool usage or omitted inspection steps. The requirement should be expressed in terms of observable objects, actions and states rather than a broad request to “manage the workstation with AI.”

A workstation may contain several risks, but an initial validation should focus on critical steps with clear boundaries and a measurable operational purpose. Accuracy, cycle-time improvement and other quantitative outcomes should not be promised before production-floor validation.

Confirm What the Production-line Camera Can Observe

A vision system can only evaluate information that the production-line camera captures consistently. The assessment should consider:

• whether the workstation, product and tools remain reasonably stable;
• whether critical actions are frequently occluded or leave the field of view;
• how lighting, reflections, shadows and operator variation affect visibility;
• whether product changeovers alter appearance or operating methods;
• whether camera placement is compatible with safety, maintenance and site rules.

If a critical state cannot be observed reliably from one viewpoint, consider changing the camera position, adding another view or adjusting the workstation guidance. Model complexity should not be used as a substitute for usable imaging.

Convert the SOP into Verifiable States

A complete operation usually needs to be decomposed into object presence, action occurrence, spatial relationships and sequence conditions. Recognising a tool alone is rarely sufficient. The system may also need to determine whether it entered the correct area, whether the required action was completed and whether the next operation is allowed to begin.

The workflow definition should include acceptable operator variation, timing boundaries and exception recovery. States that cannot be distinguished reliably through vision can be combined with barcode scanners, PLC signals, MES work orders or operator confirmation.

Define Alerts, Interlocks and Traceability

Different risks require different responses. A low-risk exception may only require a prompt or record, while a critical operation may require coordination with production control. Decide whether the response is an on-screen message, an audible and visual alert, a workflow pause, manual review or event logging.

The project should also define what images or video may be retained, how long records are stored, who may access them and which fields support traceability. Data collection should serve a clear production purpose and follow the site’s security requirements.

Use a Limited Validation to Reach a Practical Decision

Feasibility validation should use authorised, sanitised and representative samples covering normal operation, common variation and known exceptions. The outcome should document observable conditions, recognition boundaries, installation requirements, site changes, interfaces and the plan for future samples—not only a model metric.

A useful validation conclusion answers three questions: what can be evaluated reliably under current conditions; what requires additional constraints or workflow changes; and what hardware, software, integration and site support are needed for implementation. Once these boundaries are understood, the project can move into solution design with realistic expectations.
