If the business goal is to increase customer retention, which requirement should be prioritized: redesigning the homepage, a loyalty program with personalized discounts, new payment methods, or optimizing the mobile app loading speed?

To increase Customer Retention, the first step is to develop a loyalty program with personalized discounts.

Why:

• A loyalty program directly motivates customers to return and make repeat purchases.
• Personalization increases the relevance of offers, which enhances satisfaction and loyalty.

Other options are important but less prioritized:

• Redesigning the homepage can improve the first experience but does not guarantee retention.
• New payment methods are convenient but do not directly influence loyalty.
• Speed optimization is important for UX, but without motivation, customers may leave.

Thus, focusing on a loyalty program will have the most direct impact on retention.
