The accounting profession faces unprecedented workforce challenges that demand a fundamental rethinking of traditional firm structures.

Based on comprehensive research showing that 52% of firms expect to shrink by 20% or more in the next five years, participants will learn how to restructure their firms to thrive with fewer entry-level staff while expanding specialized expertise. The course explores the "6 Ps of Business Model Transformation" - Precision Hiring, Proactive Retention, Practical Technology Implementation, Pricing Expertise, Practice Area Expansion/Focus, and People Acceleration. Drawing from success stories in manufacturing, healthcare, and technology industries, attendees will discover proven strategies for accelerating staff development, implementing effective knowledge transfer programs, and building sustainable talent pipelines in an era of technological disruption and demographic shifts.
