Scientific Motivation

The authors explore three theories every sales leader should master.

Sales motivation isn’t rocket science – it’s far more complicated than that! While rockets (at least on the macro scale) follow predictable laws of physics, human motivation operates in the comparatively much messier realm of psychology, where individual differences, organizational contexts, and market pressures collide in unpredictable ways. Yet, too many sales leaders still rely on gut instinct and outdated assumptions about what drives their teams. It’s time to add some scientific rigour to the conversation.

After decades of research and practical application, three theoretical frameworks have emerged as particularly powerful for understanding sales motivation: Expectancy Theory, Goal- Setting Theory, and Self-Determination Theory. Each offers unique insights. More importantly, each provides actionable strategies that can transform how you lead your sales force.
