Lesson 4: Quality Tools and Idea Generation Flashcards
Are essential instrument used in various industries to improve processes, enhanced product quality and ensure customer satisfaction.
Quality Tools
indicates start or finish
Oval
Different quality tools
Flow Charts, Check or Tally Sheets, Pareto Chart, Fishbone Diagram, Scatter Diagram, Histogram, Control Chart
Are visual representation of processes, widely used in multiple fields to document, study, plan, improve and communicate often complex processes in clear, easy-to-understand diagrams,
Flow Charts
indicates input or output
Parallelogram
indicates decision point
Diamonds
indicates processes
Rectangle
indicates flow of direction
Arrows
A simple tool used for collecting and organizing data in a systematic manner. Typically consists of a table/form with predefined categories or criteria relevant to the task or processes being observed.
Check or Tally Sheets
A tool identified by Italian researcher named Wilfredo Pareto, popularized by Joseph Juran.
Pareto Chart
Also called as fishbone or Ishikawa diagram. It is a tool that identify and present all possible causes of a particular problem or effect.
Cause and Effect Diagram
Indicates problem or effect
Head
It is a horizontal line that points the effect
Spine
It is the main categories of potential causes
Major branches
Indicates specific causes within category
Sub-branches
It is a tool that uses cartesian coordinates to display values for two variables for a set of data useful for identifying the relationship. It is commonly used in statistics, economics, and social sciences.
Scatter Diagram
Scatter Diagram can be used in specific scenarios like:
a. Exploring relationship between variables
b. Detecting correlation
c. Identifying patterns
d. Comparing variables
e. Hypothesis testing
f. Quality control
(EDICHQ)
It is a bar chart that graphs the frequency of occurrence of continuous data and is useful tool for displaying, summarizing, and analyzing data.
Histogram
Indicates frequency or counts of data that corresponds to bins interval.
Bars
Characteristics of Histogram
- Bins
- Bars
- Continuous data
- Shape
It is the data that can take any value.
Continuous data
Indicates range of values divided.
Bins
There are (3); Normal distribution, __, and Bi-Modal distribution
Shape
Benefits of Histogram
- Visual representation of data distribution
- Identification of outliners and anomalies
- Simplifies complex data
- Educational and communicative value
