Ishikawa states the 6 Ms (also known as the 5 Ms and 1 P) as: Man, Machine, Material, Method, Measurement, Mother Nature. – Maintenance The 8 Ps (used in product marketing): Those six elements 5 Ms and on P (or 6Ms) influence variation in all processes manufacturing or not. – Mission / mother nature (purpose, environment) – Measurement / medium (inspection, environment) These have been expanded by some to include an additional three, and are referred to as the 8 Ms: These are often described as the 6Ms but feel free to use the terms that best. – Man / mind power (physical or knowledge work, includes: kaizens, suggestions) Fishbone diagrams may also be referred to as cause and effect diagrams. – Material (includes raw material, consumables, and information) Typical categories include The 5 Ms (used in manufacturing): Each potential cause is traced back to find the root cause, often using the 5 Whys technique. To help structure the approach, the categories are often selected from one of the common models shown below, but may emerge as something unique to the application in a specific case. computer to use this template Causal diagrams created by Kaoru Ishikawa Ishikawa diagramOne of the Seven Basic Tools of QualityFirst described byKaoru. This methodology can be used on any type of problem, and can be tailored by the user to fit the circumstances. On a root cause analysis (RCA), after identifying potential root cause(s), further testing will be necessary to confirm the true root cause(s). The Fishbone chart is an initial step in the screening process. The method was created by Kaoru Ishikawa in the 1960s. This diagram is used in process improvement methods to identify all of the contributing root causes likely to be causing a problem. Also known as a Cause and Effect diagram, or Ishikawa diagram. Fishbone Diagram (also known as Ishikawa Diagram) can be used to answer the following questions that commonly arise in problem solving: What are the potential root causes of a problem? What category of process inputs represents the greatest source of variability in the process output?
