In-Process Inspection Points
In-process inspection points are strategically placed within production work instructions to verify quality during manufacturing, not just at the end. These checkpoints should detail exactly what to inspect – dimensions, functionality, appearance – and how to inspect it, referencing specific tools or gauges.
Clearly define the frequency of these checks; is it every part, every tenth part, or based on a statistical sampling plan? The work instruction must specify the acceptable range for each characteristic. If a deviation is found, the procedure should outline the immediate actions: rework, scrap, or notification of a supervisor. Accurate documentation of inspection results is vital, including date, time, inspector’s initials, and any corrective actions taken. This data supports continuous improvement efforts and identifies potential process weaknesses.
Acceptance Criteria and Documentation
Acceptance criteria within production work instructions clearly define what constitutes a “good” part or completed process step. These criteria must be objective and measurable, avoiding vague terms like “acceptable” or “reasonable.” Specify tolerances, acceptable defect levels (using AQL standards if applicable), and functional requirements.
Detailed documentation is paramount. The work instruction should outline how to record inspection results – checklists, data entry into a system, or signed-off documentation. Include fields for date, time, inspector ID, part number, serial number (if applicable), and any deviations observed.
