Quality Control Methods and Inspections

Inspecting a sample of items to decide whether to accept or reject the entire batch

Inspecting supplier materials before the production process begins

Inspecting finished products after the process

Checking inputs to ensure they meet quality standards before the production process begins

Checking the production process to ensure quality standards are met throughout work

Checking finished products to ensure they meet quality standards before shipping

Quality control method used during the production process to monitor quality

Managing and controlling quality in a competitive market to ensure quality standards are met during the whole process

Procedures must be in place to prevent the distribution of products that don't meet specifications.

Firm's procedures must include identifying failure modes, assessing their risk, deciding if analysis is needed, and the depth of failure analysis.

Problems identified from data sources requiring corrective actions (e.g a recall).

Determine if the corrective actions for significant problems have addressed all related issues.

Assess if implemented procedures are successful in fixing issues and if they create new problems.

Ensure corrective or preventive actions are confirmed to be working and not harming the final product.

Corrections to reliability issues or bringing product to specifications.

Reviewing results to understand issues that may reoccur in a particular product or quality aspect.

A process used to evaluate the accuracy, precision, and stability of a measurement system. It helps determine if the system is reliable enough for making informed decisions.

To quantify the accuracy (how close to the true value), precision (repeatability and reproducibility), and stability (consistency over time) of a measurement system.

The difference between the measured value and the true value. It can include random and systematic errors.

The ability of a measurement system to consistently produce the same values over time when measuring the same sample.

MSA helps ensure that measurements are reliable enough for decision-making, especially when using data for statistical analysis, process control, or product design.

MSA is used before data-based decision making to ensure the reliability of measurements in various industries like manufacturing, healthcare, and finance.

By identifying and reducing measurement errors, MSA helps improve the quality of data used in decision-making, leading to more accurate and effective results.

Accurate measurement systems help identify true process variation and reduce unnecessary adjustments, leading to better process control.

A data-driven methodology for improving processes and reducing defects. Aims to achieve less than 3.4 defects per million opportunities.

A sub-methodology within Six Sigma used for improving existing processes. Follows five steps: Define, Measure, Analyze, Improve, Control.

A sub-methodology within Six Sigma used for creating new processes. Follows five steps: Define, Measure, Analyze, Design, Verify.

A methodology focusing on eliminating waste and inefficiencies to reduce costs and optimize processes.

A Lean tool used to visualize the flow of materials and information in a process, identifying areas of waste.

A Lean philosophy focused on continuous improvement through small, incremental changes.

In Lean, any activity that doesn't add value to the customer. Common types include overproduction, waiting, unnecessary movement, etc.

A Lean methodology focused on workplace organization and cleanliness, promoting efficiency and safety. Stands for Sort, Set in Order, Shine, Standardize, Sustain.

Someone outside of a company who purchases or uses a product or service. They are the ultimate target of a business.

A philosophy that focuses on constantly improving products and processes to meet and exceed customer expectations.

Structured approaches for identifying and eliminating waste, improving efficiency, and increasing quality in processes.

A three-step framework for process improvement: clearly define the problem, analyze its causes, and implement solutions for optimization.

The level of contentment customers have when they interact with a business and its products or services.

A group of customers who consistently choose a particular company or brand over others.

Positive internal relationships and collaboration directly impact external customer satisfaction and loyalty.

Employees who directly interact with customers, gathering insights about customer expectations.

A method to identify customer experiences that either greatly delight or significantly frustrate them.

The consistency and dependability of a product to perform its intended function.

The ease with which a customer can use and understand a product.

The pleasant and respectful attitude of employees towards customers.

The promptness and effectiveness with which service providers address customer requests and issues.

The central principle of aligning all business operations to meet and exceed customer expectations.

Establishing and implementing processes to ensure that products and services consistently meet predetermined quality standards.
