Executive Summary

Purpose

This Quality Management Plan establishes the quality standards, processes, and procedures for the KODA Multi-Tenant Beauty & Wellness Platform project. It ensures that all deliverables meet defined quality criteria and that the final product is reliable, secure, performant, and user-friendly.

Scope

This plan covers quality management for all 7 KODA applications:

1. KODA Backend (API) - Laravel 12, PHP 8.2+
2. KODA Mobile App - Flutter (iOS/Android)
3. KODA Team App - Flutter (iOS/Android)
4. KODA Website - ReactJS
5. KODA CORE Admin - ReactJS
6. KODA AI Engine - Laravel (AI/ML)
7. KODA WebSocket Service - EMQX

Quality Objectives

Quality Investment

• Total QA Hours: 488 hours
• QA Team: 1 QA Tester (dedicated)
• Security Testing: 66 hours (dedicated)
• Performance Testing: 16 hours
• Phase Distribution:
  • Phase 1: 236 hours
  • Phase 2: 82 hours
  • Phase 3: 170 hours

Quality Management Approach

Quality Philosophy

The KODA project adopts a "Quality by Design" approach:

1. Prevention over Detection - Build quality into the process from the start
2. Continuous Testing - Test early, test often, test continuously
3. Risk-Based Testing - Prioritize testing based on business impact and technical risk
4. Automation First - Automate repetitive tests to improve efficiency and consistency
5. Multi-Layered Defense - Multiple testing layers (unit, integration, system, UAT, security)

Quality Methodology

Agile-Hybrid Quality Approach:

• Sprint-Level Quality: Testing integrated into 2-week sprints
• Phase-Level Quality: Major testing milestones at phase boundaries
• Continuous Quality: Automated tests run on every commit
• Progressive Quality: Quality gates at key milestones prevent defects from propagating
