The 7 quality tools are used for capturing, organizing, visualizing, and analyzing processes and their errors with the goal of identifying, assessing, and deriving corrective actions for problems. The 7 quality tools (Q7) include: (1) Error/Data Collection List – Helps in recognizing patterns and regularities. (2) Quality Control Chart – Used for visualizing the processes being examined. (3) Histogram – Represents data distributions. (4) Pareto Chart – Used for analyzing and prioritizing errors. (5) Brainstorming – A creative technique for generating ideas. (6) Ishikawa Diagram (Cause-and-Effect Diagram) – Used for problem analysis. (7) Correlation Diagram – Helps in identifying dependencies. The tools 1 through 3 are used for problem identification, while tools 4 through 7 are employed for problem analysis.

Voice of Business (VOB) is a tool used to translate verbal statements from all areas of your company about the process causing the issues into measurable core causes. These statements often relate to financial or strategic aspects such as revenue, costs, and delivery times. A VOB must always be present.

The Voice of Process (VOP) is a tool for translating verbal statements from the process into measurable core causes. All statements in the Voice of Process should be measurable in the Define phase of the project before moving into the Measure phase. VOP is a key element in the process model =().

Lean tools are instruments used for streamlining processes. The technical goal is to reduce lead time and thereby improve efficiency.

In an MSA Type 1 a measurement system is evaluated for accuracy and precision. This involves measuring a reference part multiple times by an operator.

Measurement system uncertainty can have multiple components. In MSA Type 2, both repeatability and reproducibility are evaluated.
