1. Demonstrating Improvements
Control
Kaizen Facilitation

2. Objectives
Understand the importance of demonstrating implemented improvements with before and after data
Become familiar with different ways to display data
To visually demonstrate improvement

3. Baseline Data
Initial collection of data which serves as a basis for comparison with the subsequently acquired data
Captured during the Measure Phase
Used to identify improvement opportunities during the Analyze phase
Consists of inputs and outputs of the process
Compare Before and After

4. = Final Data Baseline vs. Final
Must be the same data points collected as the baseline data
Must be collected the same way, at the same times, by the same people =
Baseline vs Final

5. Displaying the Improvement
Final data must be compared against the baseline data… before and after comparison
Demonstrates improvement or change within the process in a manner that is easily understood by all
Generally done using graphs, charts, or tables that show side-by-side the change that has taken place as a result of the project

6. Displaying Data – Line graph
SPC graph showing baseline data compared to final data, demonstrating improvement
Built in Minitab with help of your Mentor

7. Displaying Data – Bar Chart
Demonstrating side by side comparison of annual revenues, expenses, and profit/loss
Simple bar graphs from Excel are fast and easy to build

8. Displaying Data – Bar Chart
Demonstrating side by side comparison of daily start-up waiting times (minutes to first move) after Kaizen team improvement efforts

9. Displaying Data - Table
Side by Side comparison of baseline data to demonstrate difference in services
Simple table built in Excel (KEY: more is better (+), i.e. MPH)

10. Review
Baseline data and final data must be collected in the same way to achieve an ‘apples-to-apples’ comparison
Data must be displayed visually/graphically to best demonstrate the improvement
Use the graph, chart, or table that best conveys the improvement
