• Hypothesis Testing: Multiple test types including t-tests, z-tests, ANOVA, and chi-square
• Design of Experiments (DOE): Full factorial and fractional factorial experimental designs

Lean Manufacturing Tools

• Overall Equipment Effectiveness (OEE): Track availability, performance, and quality metrics
• Value Stream Mapping (VSM): Analyze and optimize material and information flows
• Kanban System: Visual workflow management with drag-and-drop functionality
• 5S Implementation: Structure workplace organization and standardization initiatives

Continuous Improvement Tools

• A3 Problem Solving: Structured approach to problem identification and resolution
• 5 Why Analysis: Root cause analysis through iterative questioning
• PDCA Cycle: Plan-Do-Check-Act continuous improvement framework

Getting Started

Prerequisites

• Node.js 18+ installed
• npm, yarn, pnpm, or bun package manager
• Supabase account and project

Installation

1. Clone the repository:

git clone https://github.com/your-org/ci-master.git
cd ci-master

2. Install dependencies:

npm install

3. Set up environment variables: Create a .env.local file in the root directory with your Supabase credentials:

NEXT_PUBLIC_SUPABASE_URL=your_supabase_url
NEXT_PUBLIC_SUPABASE_ANON_KEY=your_supabase_anon_key

See env-template.txt for the complete list of required environment variables.

4. Set up the database: Run the SQL scripts in the following order:

• authentication-setup.sql - Authentication schema
• phase-4-database-schema.sql - Complete database schema

Development

Run the development server:

npm run dev

Open http://localhost:3000 to view the application.

Build

Create a production build:

npm run build
npm start
