Thinking Tools/Additional thinking tools

Many more thinking tools have been created and described than are covered by the Thinking Tools course. Here is a long list of known thinking tools. Over time these may be researched further, curated, organized, and adapted, and imported into Wikiversity.

Also see the list of thinking tools for solving problems.

Seven basic tools of quality
Wikipedia lists these Seven basic tools of quality:
 * Check sheet
 * Control chart
 * Stratification (alternatively, flow chart or run chart)
 * Pareto chart
 * Histogram
 * Cause-and-effect diagram (also known as the "fishbone diagram" or Ishikawa diagram)
 * Scatter diagram

Hoshin Planning, the Developmental Approach

 * The Affinity Diagram —gathers large amounts of data and organizes it into grouping based on the natural relationships between each.
 * The Interrelationship Digraph—explores and displays interrelated factors involved in complex problems. It shows the relationships between factors.
 * Tree Diagram—systematically maps out the full range of tasks or methods needed to achieve a goal.
 * Matrix Diagram—displays the relationship between necessary tasks and people or other tasks, often to show responsibility or tasks.
 * Matrix Data Analysis—shows the strength of the relationship between variables which have been statistically determined.
 * PDPC Process Decision Program Chart—maps out every conceivable event that may occur when moving from a problem statement to the possible solutions.
 * Arrow Diagram—is used to plan the most appropriate schedule for any task and to control it effectively during its progress. This is closely related to the PERT Chart.

Problem-solving methods
Wikipedia lists these problem-solving methods:
 * Eight Disciplines Problem Solving
 * GROW model

Creating Minds
The Creating Minds website lists the following tools. See: http://creatingminds.org/tools/tools_implementing.htm

Tools for implementing ideas

 * Diffusion Lifecycle: Spreading ideas one group at a time.
 * Force-field Analysis: Exploring forces that will support or oppose the idea.
 * Head, Heart and Hands: Get all three systems of motivation engaged.
 * How-How Diagram: Build plan by repeatedly asking 'how'.
 * Mind-mapping: Use a mind-map to build a plan.
 * Positives, Negatives: Look at both problems resolved and benefits gained.
 * Purposing: Finding the real purpose of how the idea will be used.
 * Remembrance: Remembering solutions not yet discovered.
 * Reverse Planning: Working backwards from a perfect future.
 * Role-play: Become other people you must persuade. Let them tell you what to say.
 * Rubber-ducking: Talk about the problems you are facing to someone else.
 * Six Thinking Hats: Look at the idea from the viewpoint of your customers.
 * Storyboarding: Creating a visual story to explore or explain.
 * Why not?: Challenge objections and assumptions.

Total Design, Integrated Methods for Successful Product Engineering


In this book Stuart Pugh describes “Total Design” which he defines as: “… the systematic activity necessary, from the identification of the market/user need, to the selling of the successful product to satisfy that need – an activity that encompasses product, process, people and organisation.”

Prominent among the techniques is Pugh concept selection a method of controlled convergence.
