Quality Management Tools

As a structured management system, SMS uses many tools from the quality management. The most popular are:

  1. Cause & Effect/ Ishikawa/ Fishbone Diagram
    Sorts ideas into useful categories
    Records causes of a particular and specific problem
    Helps identify the root cause and potential factors
    Requires a structured brainstorming session
  2. Check Sheet
    Collects info and data easily in a quantitative and qualitative way
    List of issues – helps to tackle and organise the problem (divide and organise problems by significance or urgency)
    Used for data observed repeatedly regarding frequency, patterns and defects
  3. Control Charts
    Shewhart charts used to determine control state of manufacturing or business process
    Detects observations out of set limits (upper and lower band) and tracks how process changes over time
    Allow simple detection and provide early warnings
    Great for ongoing processes predicting expected ranges, checking stability and checking for patters
  4. Histogram
    Graphical presentation of the frequency and distribution for numerical data.
    It can show the intensity of a problem
    Shape and width of distribution can identify patterns and stability
    Great tool when we have a lot of numerical data and we analyse the output
  5. Pareto Chart
    Bar graph showing the significant factors, helping identify and prioritising problems based on frequency
    Bars are helpful for individual observations whilst line is showing the total number
    It can highlight the most important (significant) problem
    Helpful tool for data involving frequency and data with many factors
    Helps analysis of a broader causes by looking at specific components
  6. Scatter Diagram
    Shows relationship between sets (variables) of numerical data
    Good for continuous observations
    Identifies the correlation of variables
    Good for paired variables
    Objectively identifying relationship after RCA and brainstorming sessions
  7. Stratification
    A combination technique that separates data to aid clarification and picture patters
    Great for when data come from various sources and require different separated sources/ conditions (e.g. equipment, shifts, departments, suppliers, time of day, product etc)
