How it Helps:
2. Pareto Chart
What is a Pareto Chart? A Pareto chart is a bar chart that prioritizes issues or causes by showing which factors contribute the most to a problem. It follows the Pareto principle, suggesting that a small number of causes (the "vital few") often account for the majority of the problems.
How it Helps:
3. Hypothesis Testing
What is Hypothesis Testing? Hypothesis testing involves using statistical methods to analyze data and test hypotheses about potential root causes. Common tests include t-tests, chi-square tests, and ANOVA (Analysis of Variance).
How it Helps:
4. Scatter Plot
What is a Scatter Plot? A scatter plot displays data points on a two-dimensional graph, with one variable on the x-axis and another on the y-axis. It is used to explore relationships and correlations between variables.
How it Helps:
5. Five Whys Analysis
What is 5 Whys Analysis? The 5 Whys technique involves repeatedly asking "Why?" to dig deeper into the root cause of a problem. By asking "Why?" five times (or more), it aims to uncover the underlying issues.
How it Helps:
In the Improve phase of the DMAIC methodology, the focus shifts to developing and implementing solutions to address the root causes identified during the Analyze phase. The following DMAIC tools and techniques are instrumental in driving process improvement:
1. Brainstorming
