Project Overview

A serverless Six Sigma analytics dashboard for ecommerce businesses built on Google Cloud Platform. This application provides real-time quality metrics, statistical process control, and DMAIC methodology tracking to help optimize business processes and reduce defects.

Goals of this project:

• Implement Six Sigma methodology in ecommerce analytics
• Use serverless GCP architecture for scalable analytics processing
• Provide real-time quality metrics and control charts
• Enable data-driven process improvement decisions
• Cost-effective infrastructure for small to medium businesses
• Infrastructure as Code (IaaC) approach
• Implement CI/CD for continuous deployment

Key Features

Six Sigma Analytics

• Statistical Process Control (SPC) - X-bar, R, p, np control charts
• Process Capability Analysis - Cp, Cpk, Pp, Ppk calculations
• DMAIC Tracking - Define, Measure, Analyze, Improve, Control phases
• Defect Analysis - DPMO (Defects Per Million Opportunities)
• Sigma Level Calculator - Real-time process sigma level monitoring
• Pareto Analysis - Root cause identification and prioritization

Ecommerce Metrics

• Order fulfillment time variations
• Product return rate analysis
• Customer satisfaction distribution
• Shipping accuracy tracking
• Inventory turnover consistency
• Process performance dashboards

Architecture

Serverless Infrastructure

Components:

• Frontend: React TypeScript with Material-UI for analytics dashboards
• Backend: Node.js Cloud Functions for data processing and Six Sigma calculations
• Database: Firestore for storing process data and historical metrics
• API Gateway: Routes requests and handles authentication
• Cloud Storage: Static asset hosting and data export storage
• Authentication: Google OAuth 2.0 integration

Benefits of this Architecture:

• Cost-effective: Free tier covers ~2M API calls per month
• Highly scalable: Auto-scaling serverless functions
• No server management: Focus on analytics, not infrastructure
• Real-time processing: Cloud Functions for immediate metric calculations
• Secure: Google OAuth with JWT token authentication
• Fast deployment: Infrastructure provisioned in minutes
• Open technology stack: Node.js, React, Terraform, GitHub Actions

Prerequisites

Required Tools

• Node.js (>= 18.0.0)
• Terraform (for infrastructure)
• Google Cloud SDK (optional)

GCP Setup

Enable the following APIs in your GCP project:

• Cloud Functions API
• Cloud Firestore API
• API Gateway API
• Cloud Storage API
• IAM Service Account Credentials API
• Secret Manager API

Service Accounts

Create service accounts for:

• GitHub Actions (CI/CD)
• Local development
• Production deployment

Quick Start

1. Clone and Setup

git clone <repository-url>
cd six-sigma-analytics-dashboard

2. Frontend Development

cd frontend/client-app
npm install
npm start

Dashboard will be available at http://localhost:3000

3. Backend Development

cd backend/service-analytics
npm install
npm run dev

API will be available at http://localhost:8080

4. Infrastructure Deployment

cd infra
terraform init
terraform plan
terraform apply

Data Sources

The dashboard supports mock data generation for development and testing. In production, you can integrate with:

• Ecommerce APIs: Shopify, WooCommerce, BigCommerce
• Analytics APIs: Google Analytics, Adobe Analytics
• Business Systems: ERP, CRM, Order Management Systems
• Custom APIs: Your existing business systems

Six Sigma Methodology

DMAIC Process Support

• Define: Problem definition and goal setting
• Measure: Data collection and baseline establishment
• Analyze: Root cause analysis and process mapping
• Improve: Solution implementation tracking
• Control: Ongoing monitoring and sustainability

Key Metrics Calculated

• Process Capability: Cp, Cpk, Pp, Ppk
• Sigma Level: Real-time process sigma calculation
• DPMO: Defects Per Million Opportunities
• Control Limits: Statistical process control boundaries
• Trend Analysis: Process performance over time
