Continuous Improvement
1. What Is Continuous Improvement?
Section titled “1. What Is Continuous Improvement?”Continuous improvement is an iterative approach that aims to constantly optimize digital products, services, or interfaces by relying on user feedback, usage data, and testing.
It’s a mindset: never consider a solution as “final”.
2. Objectives of Continuous Improvement
Section titled “2. Objectives of Continuous Improvement”| 🎯 Objective | 🔧 Expected Result |

| Test new hypotheses | Innovate incrementally |
| Strengthen user retention | Reduce churn |
3. The Deming Cycle (PDCA)
Section titled “3. The Deming Cycle (PDCA)”The PDCA cycle is a well-known method for managing continuous improvement:
| Step | Description |
|---|---|
| P – Plan | Identify a problem, form a hypothesis, define an objective |
| D – Do | Implement a solution or variation |
| C – Check | Measure results (KPIs, user feedback) |
| A – Act | Adjust, correct, or deploy based on the results |
Tip
💡 This cycle is infinite — iteration is constant.
