"Productivity is the ratio of output to inputs in production; it is an average measure of the efficiency of production. Efficiency of production means production’s capability to create incomes which is measured by the formula real output value minus real input value.
Productivity is a crucial factor in production performance of firms and nations. Increasing national productivity can raise living standards because more real income improves people's ability to purchase goods and services, enjoy leisure, improve housing and education and contribute to social and environmental programs. Productivity growth also helps businesses to be more profitable." [Productivity. Wikipedia]
The fishbone diagram example "Increase in productivity" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Fishbone Diagrams solution from the Management area of ConceptDraw Solution Park.

"Cause-and-effect diagrams can reveal key relationships among various variables, and the possible causes provide additional insight into process behavior.
Causes can be derived from brainstorming sessions. These groups can then be labeled as categories of the fishbone. They will typically be one of the traditional categories mentioned above but may be something unique to the application in a specific case. Causes can be traced back to root causes with the 5 Whys technique." [Ishikawa diagram. Wikipedia]
"The 5 Whys is an iterative question-asking technique used to explore the cause-and-effect relationships underlying a particular problem. The primary goal of the technique is to determine the root cause of a defect or problem. (The "5" in the name derives from an empirical observation on the number of iterations typically required to resolve the problem.)" [5 Whys. Wikipedia]
