Lean and Six Sigma aid in the production of musical instruments. We’ll see how Lean and Six Sigma improve the quality of piano manufacturing and the production of musical instrument strings, and finish with a video of how trumpets are made.
Six Sigma DMAIC Phases Applied to Piano Manufacturing: Indonesia
In a paper titled “Minimization of Defective Products in The Department of Press Bridge & Rib Through Six Sigma DMAIC Phases,” authors Y.A. Rochman and A. Agustin discuss the use of Six Sigma DMAIC phases in piano manufacturing.
Five defect types were dominant in piano manufacturing: broken ribs, broken sound boards, strained ribs, rib sliding, and Minori soundboard.
The paper includes:
- SIPOC Diagram
- Current State Value Stream Map
- Pareto Charts of Rib Defects and Sound Board
- Fishbone Diagrams for Each of Five Defect Types
- FMEA Analysis
- Proposed Solutions Based on FMEA Analysis
