Pareto Charts

Based on the Pareto principles (80 / 20 rule), a Parete chart is a combination of a bar graph and a line graph.

Step-by- Step Integration Framework

Instad of using these tools sequentially in separate workflows, embed them into a single quality improwizuj cykle. The following framework outlines how tocombinate FMEA, Pareto analysis, and fishbone diagrams effectively.

Step 1: Przeprowadź tę inicjatywę FMEA

Rozpocząć pracę w zespole FMEA of your process or product. Assemble a cross- functional team (design, producturing, quality, consulance, and sumpliers if relevant). Identify each functionon or step, then ligt all plausible faidure modes. For each failure mode, assign Severity, Occurrence, and Detection scores using your organization 's rating scales (e.g., 1- 10). Calculate RPN = S × O. Document faifure effects and d controlt.

Krok 2: Ekstrakt Data for Pareto Analysis

From the FMEA table, extract the failure modes alongwigh a metric you want to prioritize. Common options include:

Te root causes identified by the fishbone diaglem of ten reveal gaps in thee original FMEA controls. For example, thee fishbone may expose that a machine calibration procedure is missing or that operator training is independent. These findings should be use te update thee FMEA: add missing fafficure causes, adjuss Octerce ratings, modify Detection ratings, and approposite new recommended actions.

With root causes uncovered, create action items for each. Assign owners, deadlines, and verification methods. Prioritize actions based on thee same Pareto logic: use a second Pareto chart on thee root causes themselves if there are many. Actions may included de redesignising a dimendent, adding inspection steps, updating work instructions, installing pokake (error -proofing) devices, or improwimining sumlier qualis.

Hierarchical Fishbone Linked to FMEA Functions

When a failure mode has multiple causes, create separate fishbone diagrams for each cause-effect path. Then use a cause-and-effect matrix (C recurmp; E matrix) to score the recorseship between root causes andd faifure modes, fediing results back into the FMEA 's Occurrenci Ratings. This formazed approvach is contran in Design for Six Sigma and Advanced Product Quality Planning (APQP).

Pareto Analysis of Fishbone Categories

After completing fishbone diagrams for several top failure modes, tally how many root causes fall under each category (np. 60% are Method- related, 20% are Material- related). Build a Pareto chart of these methodories across failure modes. Thii s reveals systemic weaknesses in your process - for example, if mott rot causes are Method- related, u can pritize developiing better standard work procedures rather faixing ong machine a time.
