Lecture 13 Flashcards
What are Quality Tools in Industry used for?
Quality tools are employed to monitor quality, ensure continuous process improvement, and verify product quality, especially in pharmaceutical and biopharmaceutical industries.
What is a Check Sheet and what is its purpose?
A check sheet is a structured form for collecting and analyzing data, often using lists or diagrams. It is particularly useful when data is collected repeatedly by the same individual or location.
What is a Pareto Chart and its use?
A Pareto chart is a specialized bar graph that represents the frequency or cost of different factors, helping to prioritize issues by highlighting the most significant factors affecting a system.
What is a Flowchart used for in industry?
A flowchart is a pictorial representation of processes, breaking down complex operations into steps. It helps identify potential error points, clarify process sequences, and highlight discrepancies between intended and actual process paths.
What is a Cause and Effect Diagram (Fishbone Diagram)?
A cause and effect diagram visually links multiple potential causes to a single effect. It is used to systematically identify and organize possible root causes of a problem.
What is a Histogram and its purpose?
A histogram graphically depicts the frequency distribution of data, offering a simplified view of how data is distributed. It is similar to a bar chart but has key differences in use.
What is a Scatter Diagram and how is it used?
A scatter diagram plots pairs of numerical data on two axes to explore potential relationships between variables, helping to identify correlations.
What is a Control Chart and what does it monitor?
A control chart monitors process changes over time, featuring a central line for the average, an upper control limit, and a lower control limit. It helps identify whether a process is in control or out of control.
How do you construct a Cause and Effect Diagram for QC Analysis?
Define the problem clearly (this forms the ‘head’ of the diagram).
Identify major cause categories (e.g., People, Methods, Materials).
Brainstorm potential causes for each category.
Further break down crowded sections into sub-branches.
Prioritize and investigate the root causes.
