Think about your favourite local shop — maybe the one where the owner remembers your name, asks about your kids, and knows exactly what you like. That personal touch keeps you coming back. Now imagine trying to give that same feeling to millions of customers across a website, a mobile app, a call centre, and a dozen stores. That is exactly the challenge Customer Relationship Management (CRM) solves. It is the art and science of knowing your customers so well that every interaction feels personal, even when you are a giant company.
