To make the idea concrete, imagine two small trucking companies in the same town. Both have three trucks, similar rates and good drivers.
The first company relies on the owner’s phone. When he is driving or meeting a client, calls go unanswered. Quotes are sent when he finds time in the evening. If a customer does not reply, he assumes they went elsewhere. Reviews are something he means to ask for one day. At the end of each month he knows roughly how busy he was, but not why.
The second company has the same three trucks, but it works differently. Every enquiry, whether by phone, WhatsApp or the website, is logged in one place. Someone answers within the hour during working times. Quotes go out the same day using a clear template, and every quote is followed up after two days and again after five. When a load is delivered, the customer receives a short thank-you message with a link to leave a review. Once a month the owner looks at five numbers: enquiries, quotes sent, quotes won, average job value and repeat customers.
Neither owner works harder than the other. But after a year, the second company has more reviews, more repeat customers, a better reputation online and a far clearer view of where its next growth will come from. That difference is what the book means by a system.
