Introduction
Machine changeovers are a critical bottleneck in manufacturing. Every minute spent in setup is a minute of lost production. Traditional paper-based checklists and tribal knowledge lead to inconsistency, errors, and wasted time. **Changeover Master** is the modern solution — a fully offline, production-grade changeover suite designed to transform how operators manage product transitions.
What is Changeover Master?
Changeover Master is a comprehensive application built for machine operators, setup teams, and production supervisors. It digitizes the entire changeover process, providing:
- **Guided changeover steps** that ensure no critical task is skipped.
- **Reference photos** for visual confirmation of correct setups.
- **Tool and material lists** to prepare everything in advance.
- **Built-in timers** to track each phase and identify improvement areas.
- **First-piece inspection** checklists to verify quality before full production.
- **Approval workflows** for supervisor sign-off when deviations occur.
- **Shift comparison** to highlight best practices and drive continuous improvement.
Key Features
Complete Changeover Workflow
The app breaks down the changeover into clear, sequential steps. Operators can check off each task as it's completed, ensuring nothing is forgotten. The steps are fully customizable to match your specific machines and products.
Reference Photos & Asset Library
A picture is worth a thousand words. Store reference photos of correct setups, tooling, and materials in the Asset Library. Operators can quickly access these images during changeovers, reducing ambiguity and errors.
Precision Timing
Each changeover phase can be timed individually. The app records start and end times, allowing you to analyze where time is spent and identify bottlenecks. The dashboard displays trends and averages to support SMED initiatives.
First-Piece Inspection (FPI)
Quality is non-negotiable. Changeover Master includes a first-piece inspection checklist that must be completed before production can begin. Operators verify critical dimensions and quality attributes, and the results are logged for traceability.
Approvals and Deviations
Sometimes things don't go as planned. If a deviation occurs, the operator can flag it, and the app routes it for approval by a supervisor. This ensures that any out-of-spec condition is properly documented and authorized.
Shift-to-Shift Comparison
One of the most powerful features is the ability to compare changeover times across shifts. This data-driven approach reveals which teams are performing best and provides a basis for coaching and recognition.
Fully Offline & No Sign-Up
Changeover Master runs entirely in the browser using IndexedDB for local storage. It works seamlessly without an internet connection, making it ideal for factory floors. No user accounts, no cloud, no data privacy concerns — just instant access.
Who Is It For?
- **Machine Operators**: Execute changeovers with confidence, following a proven checklist.
- **Setup Teams**: Collaborate efficiently and share best practices.
- **Production Supervisors**: Monitor changeover progress in real-time and approve deviations.
- **Continuous Improvement Engineers**: Analyze changeover data to drive SMED projects.
Why Choose Changeover Master?
- **Speed**: Reduce changeover times by standardizing procedures and eliminating waste.
- **Safety**: Ensure all safety steps are completed before starting the machine.
- **Quality**: Catch defects early with first-piece inspection.
- **Reliability**: Works offline, so it's always available when you need it.
- **Simplicity**: No complex setup or training required — intuitive interface designed for the floor.
How to Use
1. **Create a Changeover**: Click "New Changeover" and select the machine, from-product, and to-product. 2. **Follow the Steps**: Work through the guided checklist, checking off each task. 3. **Use Reference Photos**: Access the Asset Library to view correct setups. 4. **Track Time**: The app automatically times each phase; manually start/stop if needed. 5. **Perform First-Piece Inspection**: Complete the FPI checklist before production. 6. **Review Results**: After completion, the changeover is logged and available for analysis.
