# Coaches

Use coaches to learn how and when to use specific continuous improvement templates. Coaches provide guidance for every Qeystone template.

Coaches are organized by the following categories:

ANOVA
ANOVA tests the hypothesis that the means of two or more populations are equal. The coaches in this section include Equal Variances Test, Main Effects Plot, and One-Way ANOVA.
Basic Statistics
Basic statistics are tests that analyze data and quantify accuracy. Some coaches in this section include 1- and 2-Sample t, 1 Variance Test, Chi-Square tests, Correlation, and Normality.
Brainstorming
Brainstorming is a problem solving technique that requires contributions from members of a group. The coaches in the section help to facilitate brainstorming and include CT Tree, Idea Map, and several variations of Fishbone.
Control Charts
Control charts plot your process data in time-ordered sequence to help identify common cause and special cause variation. Some coaches in this section include C, I-MR, NP, P, and U Charts, as well as Deviation from Nominal Chart and Xbar-R/S Chart.
Controls
Controls are quality-improvement methods you use to keep the process in control. Some coaches in this section include 5S Audit, Control Plan, FMEA, and Solution Implementation Checklist.
Decision Tools
Decision tools provide semi-scientific methods to help you to determine or select the best solution or strategy for achieving improvement goals. The coaches in this section include C&E Matrix, House of Quality Matrix, Pugh Matrix, and the Solution Desirability Matrix.
DOE (Design of Experiments)
A designed experiment is a series of runs, or tests, in which you purposefully make changes to input variables simultaneously and observe the responses. Some coaches in this section include 2K Factorial DOE, Contour Plot, Interactions Plot, Mixture DOE, Response Surface DOE, and Path of Steepest Ascent.
Graphs
Graphs allow you to visualize the data so you can make comparisons, see relationships, and more. Some coaches in this section include Bar Chart Worksheet, Boxplot, Histogram, Scatterplot Worksheet, and Time Series Plot.
Maps
Maps provide a graphical presentation of a process. The coaches in this section include Process Map, Cross-Functional Process Map, and Value Stream Map.
Metrics
A metric is a quantifiable measure used to track and monitor a process. Some coaches in this section include Capability Averaging Report, Cumulative Metrics, Six Sigma Process Report, and Value Stream Map Comparison.
Nonparametrics
A nonparametric test is a hypothesis test that does not require the population's distribution to be characterized by certain parameters. The coaches in this section include 1-Sample Sign, 1-Sample Wilcoxon, Kruskal-Wallis, Mann-Whitney, and Mood's Median Test.
Project Management
The coaches in this section help you scope, document, and organize your project. Some of the coaches include Data Collection Planner, Funnel Report, Project Charter, and SIPOC.
Project Selection
When selecting a project, it's important to consider the benefits, the risks, and stakeholder impact. The coaches in this section include Project Prioritization Matrix, Project Risk Assessment, and Stakeholder Analysis.
Quality Tools
Quality tools allow you assess different aspects of a process such as its capability and variation, the accuracy of its measurement system, and the impact of inputs on outputs. Some coaches in this section include Attribute Agreement Analysis, Capability Analysis, and Gage R&R Study, Pareto Chart, and Run Chart.
Regression
Regression generates an equation to describe the statistical relationship between one or more predictors and the response variable and to predict new observations. Some coaches in this section include Best Subsets Regression, Fitted Line Plot, Multiple Response Optimization, and Stepwise Regression.
