I'm a huge fan of the late author Napoleon Hill. You might know him from his highly successful book called "Think and Grow Rich," but If you're going to research more about his work, you'll discover his other book called "The Law of Success."
Hill had the once in a lifetime chance to spend 20 years of his life studying the business magnates of the early 20th century. As you go through the book, you'll realize that there are a few people that had a big influence on him including Andrew Carnegie who initiated HIll's work and Henry Ford whose business gave great insight to his learning.
Henry Ford is most interesting because he revolutionized the process of manufacturing automobiles by refining the concept of the Assembly Line. This constant development and systemization were grown by bringing his team to the slaughterhouses of Chicago and watching how the meat packing process worked and applying the concept of specialized workers to the manufacturing of cars. He also studied Sears and Roebuck's systems for managing the process of delivery to get their products closer to their customers.
To apply Henry Ford's ideas to the real estate agency, look at your business and ask yourself "what would Henry Ford do?" The fact might be that he would see that you're not "selling" properties, rather you're "manufacturing relationships" that lead to a property sale. Therefore, to make your business consistent and predictable, you'll need to constantly manufacture new relationships. That's why committing to the buildout of better Contact Relationship Management (CRM) is a necessity. Your CRM becomes the assembly line for manufacturing relationships that produces happy clients.
To summarize the key point: “Be Like Henry: Understand & Study The Process Systems Of Successful Businesses.”
