Russell Cummings provides a strategic business development worksheet to help businesses plan for the next 3-5 years, 1 year, and 90 days. The document outlines key questions and areas for businesses to focus on, including defining their destination and priorities for the next 12 months, examining their products/services, processes, people, and profits, and identifying specific actions they must take in the next 90 days to move toward their goals. It emphasizes the importance of having a clear vision, taking action, and collaborating with a support team.
