Data Collection Tools
4 Tools for Process Analysis Check sheets Control Charts Flowcharts Process Analysis Tools Pareto diagrams Histograms Scatter diagrams Cause & effect diagrams
Flowcharts Flowchart or process map identifies the sequence of activities or the flow of materials and information in a process  Flowcharts help the people involved in the process understand it much better and more objectively by providing a picture of the steps needed to accomplish a task 5
Flowcharts - Benefits Serves as a training tool Compares and contrasts actual versus ideal flow of a process Allows a team to reach agreement on process steps and identify activities that may impact performance Shows unexpected complexity, problem areas, redundancy, unnecessary loops, and where simplification may be possible 6
Check Sheets Check sheets are special types of data collection forms in which the results may be interpreted on the form directly without additional processing
Check Sheets - Benefits Creates easy-to-understand data  Makes patterns in the data become obvious quickly Builds, with each observation, a clearer picture of the facts Forces agreement on the definition of each condition or event of interest 8
Histograms Histograms provide clues about the characteristics of the parent population from which a sample is taken Patterns that would be difficult to see in an ordinary table of numbers become apparent
Histograms - Benefits Shows centering, variation, and shape Illustrates the underlying distribution of the data Provides useful information for predicting future performance Displays large amounts of data that are difficult to interpret in tabular form Helps to answer “Is the process capable of meeting requirements? 10
Pareto Diagrams  Pareto distribution is a histogram of the data where the data characteristics are observed and ordered from largest frequency to smallest
Pareto Diagrams  - Benefits Helps a team focus on causes that have the greatest impact Displays the relative importance of problems in a simple visual format Helps prevent “shifting the problem” where the solution removes some causes but worsens others 12
Cause-and-Effect Diagrams A cause-and-effect diagram is a simple graphical method for presenting a chain of causes and effects and for sorting out causes and organising relationships between variables
Cause-and-Effect Diagrams  - Benefits Focuses the team on causes, not symptoms’ Enables a team to focus on the content of a problem, not on the history of the problem or differing personal interests of team members Creates a snapshot of collective knowledge and consensus of a team; builds support for solutions 14
Scatter Diagrams A scatter diagram is a plot of the relationship between two numerical variables
Scatter Diagrams - Benefits Provides a good follow-up to cause and effect diagrams Supplies the data to confirm a hypothesis that two variables are related Provides both a visual and statistical means to test the strength of a relationship 16
Control Charts Control charts show the performance and the variation of a process or some quality or productivity indicator over time in a graphical fashion that is easy to understand and interpret They also identify process changes and trends over time and show the effects of corrective actions
Control Charts - Benefits Distinguishes special from common causes of variation  Focuses attention on truly vital changes in the process Monitors performance of one or more processes over time to detect trends, shifts, or cycles Allows a team to compare performance before and after implementation of a solution to measure its impact 18
