This document discusses the importance of incorporating an annual budget into a business plan using a validated budget model. It notes that while most successful agencies update their business plan yearly, only 59% of average agencies do. The traditional approach of simply adding 10% to the previous year's revenue is inaccurate. Instead, a validated budget model requires collaboration between leaders to balance organic revenue growth expectations with past production results to set achievable goals. This allows accurately predicting revenue over two to three years by considering retention rates and historical new business performance by producer. The validated budget model helps understand capabilities and growth drivers while identifying changes to achieve sustainable growth.
