Red Bead Experiment

A SwiftUI iOS application implementing the Red Bead Experiment by W. Edwards Deming.

Overview

The Red Bead Experiment is a quality management demonstration that illustrates the concept of variation in processes. This app allows you to:

• Track multiple workers and their daily white bead counts
• Visualize performance data using statistical control charts
• Calculate control limits (mean ± 3σ) to understand natural process variation
• Record and analyze data across multiple days

Requirements

• iOS 16.0+
• Xcode 14.0+
• Swift 5.7+

Getting Started

1. Open Red Bead Experiment/Red Bead Experiment.xcodeproj in Xcode
2. Select your target device or simulator
3. Build and run (⌘R)

Features

• Worker Management: Add workers and track their individual performance
• Daily Entry: Record bead counts for all workers simultaneously
• Control Charts: Visualize worker performance with statistical control limits
• Worker Details: View detailed history for individual workers
• Reset: Clear all data to start a new experiment

Architecture

Built with SwiftUI and Swift Charts, using an ObservableObject pattern for state management. See CLAUDE.md for detailed architecture information.
