2. 7 Basic Quality Control (QC’s) Tools 7 New Quality Control (QC’s) Tools. QUALITY CONTROL is a systematic approach used to ensure that products or services meet predefined standards of quality. It involves a series of activities and inspections throughout the production or service delivery process to identify and correct any deviations or errors. Statistical Tools Applied after problems occur Analysis & Problem-solving Identifying root causes Corrective actions Non-statistical Tools Applied Before problems occur Planning & Prevention Identifying potential problems Preventive actions

4. It is a data collection instrument used to record the frequency and occurrence of specific events, defects, or characteristics within a process. Check sheets can be used to collect quantitative or qualitative data. When used to collect quantitative data, they can be called a tally sheet. CHECK SHEETS

5. Control Chart A graph used to track the performance of a process over time and identify whether it is operating within acceptable limits. It used to identify when the process is going out of control. Histogram The most commonly used graph for showing frequency distributions, or how often each different value in a set of data occurs. It was first introduced by Karl Pearson

6. Pareto Chart Pareto charts are a combination of bar and line graphs. It is a visual representation of how often the various issues affecting a process are occurring. Pareto chart derives its name from Italian economist Vilfredo Pareto . Pareto 80:20 principle states “80% of the effect comes from 20% of the causes.” Using this chart, professionals can decide where to place priority and focus

7. 8 SCATTER PLOT This graph reveals the relationship between two variables, helping you visualize how changes in independent variable might affect the dependent variable . It's useful for identifying potential correlations and root causes of problems. STRATIFICATION Dividing data into smaller, more manageable groups based on a common characteristic, like time, location, or operator. This allows for targeted analysis and identification of specific factors influencing process variations.

8. Cause & effect diagram (Ishikawa diagram) This is used to brainstorm and identify the root causes of a problem by categorizing them into major factors like people, methods, materials, machines, and environment. Where, t he head of the fish represent problem and the bones represent causes

10. Affinity Diagram Purpose: Organize a large number of ideas into natural groups based on their relationships. Method: Write down all ideas on sticky notes, group them based on similarities, and refine the groups until a clear structure emerges. Example: Brainstorming customer complaints and grouping them by product features or types of issues. Affinity Diagram was Created in 1960’s by Japanese anthropologist Jiro Kawakita

11. 12 Purpose: Identify the cause-and-effect relationships between different factors in a complex situation. Method: Draw arrows between factors indicating the direction of influence. Interrelationship Digraph Method: Start with the main problem at the top and branch out to sub-problems, then further subdivide until specific actions are identified. Purpose: Break down a broad problem or goal into smaller, more manageable sub-problems or tasks. Tree Diagram

12. 13 Matrix Diagram Purpose: Analyze the relationships between multiple factors and their impact on a desired outcome. Method: Create a matrix with factors on both axes, and then fill in cells with symbols or numbers representing their relationships and impact.

13. 14 Process Decision Program Chart PDPC This tool is a version of the tree diagram that is designed to identify all that might go wrong in a plan under development . In other words, it is used for forecasting the failures that may happen while the implementation of the project With the help of this tool, we can revise our project steps that might go wrong. Activity Network Diagram / Arrow Diagram Purpose: Plan and schedule tasks for a project, considering their dependencies and durations. We can optimize the tasks and process of our project with the help of this tool. Diagram is broadly used in PERT and CPM. Method: Represent tasks as nodes and their relationships as arrows, indicating the order and duration of each task.

14. 15 The Prioritization Matrix is a L-Shaped matrix that compares a list of options/needs to a set of criteria, in order to help choose the best options when too many options are available, or to set the options in order of priority.  Method: Use matrices like the " Importance-Performance Analysis " or the " Urgent-Important Matrix " to categorize tasks based on their impact and time sensitivity. Prioritization Matrices / Matrix Data Analysis URGENT NOT URGENT IMPORTANT NOT IMPORTANT
