Roles and Responsibilities
Quality Control Inspectors play a critical role in ensuring that products are of high quality and meet customer requirements. Their work includes examining raw materials, equipment, and reviewing the production plans. The following is a breakdown of the roles and responsibilities that QCI’s have at various production stages.
A. Pre-Production Inspection
Before the production phase commences, the QC inspector inspects raw materials and evaluates the quality of materials to ensure they meet standards. Additionally, they inspect the equipment to ensure that it is in good working condition to avoid production delays. The QC Inspector reviews the production plans to assess if they adhere to quality standards.
Raw Materials Inspection: QC inspectors examine the quality of materials even before production begins. The inspector will verify if raw materials meet the specified requirements, such as the size, color, and shape specified in the production plan.
Equipment Inspection: QC inspectors verify that the equipment used in the production process are in good condition. They check for any wear and tear, correct installation, alignment, and cleanliness.
Reviewing Production Plans: QC inspectors vet production plans to ensure they adhere to quality standards. The inspector confirms that the plan is adequate for successful production, fulfillment of customer specifications, and no quality is compromised.
B. During Production Inspection
During production, QC inspectors monitor the production processes to eliminate any chances of errors or deviations from the production plan. The inspector conducts tests and measurements to identify any defects that could compromise the product’s quality.
Monitoring Production Processes: QC inspectors assess production processes to ensure that they comply with the production plan. If the production deviates from the production plan, QC inspectors take immediate action to rectify the issues.
Conducting Tests: QC inspectors carry out various tests to identify defects during the production process. For example, an inspector would test the hardness of a biscuit by breaking it to avoid compromising its quality during distribution.
Assuring Compliance with Standards: QC inspectors confirm compliance with safety and hygiene standards such as the use of Personal Protective Equipment( PPE) by workers, Good Manufacturing Practices(GMP), and other regulations.
C. Post-Production Inspection
After production is complete, the QC inspector recounts activities during the production process and documents the results. Additionally, the QC inspector shares feedback with other relevant departments.
Documenting and Reporting Results: QC inspectors prepare and maintain thorough records of the production process alongside conducting an evaluation of the overall outcome to ensure that the final product meets quality standards.
Sharing Feedback: QC inspectors share feedback regarding the production process with relevant departments such as product development, engineering, and management. The feedback aims to identify any production errors that could be rectified to improve the product’s quality, reduce downtimes, and streamline production processes.
Tools and Techniques Used
Quality control inspectors rely on a variety of tools and techniques to ensure the products they are overseeing meet the required standards of quality. Here are five of the most commonly used tools and techniques:
A. Statistical Process Control
Statistical process control (SPC) is a set of statistical methods used to measure and monitor the quality of a product or process. The goal of SPC is to identify when a process is operating outside of its normal range and take corrective action before defects occur. The main tools used in SPC are control charts, which graphically display data over time, and statistical analysis, which identifies trends or patterns in the data. SPC is particularly useful in identifying and correcting defects in manufacturing processes.
B. Root Cause Analysis
Root cause analysis (RCA) is a problem-solving technique used to identify the underlying cause of a problem or defect. The goal of a root cause analysis is to identify the source of a problem, rather than just treating its symptoms. RCA involves a systematic investigation of the problem, often using techniques like the 5 Whys or Ishikawa diagram, to identify the root cause. Once the root cause is identified, corrective action can be taken to prevent similar problems from occurring in the future.
C. Lean Manufacturing
Lean manufacturing is a methodology that focuses on eliminating waste in the production process. The goal of lean manufacturing is to create a more efficient production process by identifying and eliminating process steps that do not add value. The main tools used in lean manufacturing are value stream mapping, which identifies areas of waste in the production process, and continuous improvement, which involves ongoing efforts to optimize the efficiency of the production process. Lean manufacturing is particularly useful in reducing the time and cost of production while increasing the quality of the final product.
D. Six Sigma
Six Sigma is a data-driven approach to problem solving that aims to achieve near-perfect quality in all aspects of a process. The goal of Six Sigma is to reduce variability in the production process and minimize defects. Six Sigma involves a five-step process known as DMAIC: Define, Measure, Analyze, Improve, and Control. The main tools used in Six Sigma include statistical analysis, process mapping, and control charts. Six Sigma is particularly useful in identifying and eliminating defects in complex production processes.
E. Failure Mode and Effects Analysis
Failure mode and effects analysis (FMEA) is a technique used to identify and analyze potential failures in a product or process. The goal of FMEA is to identify potential failure modes and their effects, assess the severity of the potential failures, and take corrective action to prevent the failures from occurring. FMEA involves a systematic evaluation of each potential failure mode, its likelihood of occurrence, and its impact on the final product or process. FMEA is particularly useful in identifying potential defects early in the production process and taking corrective action to prevent them from occurring.
