Dominant Force

Dominant Force is a foundational concept in the JTBDUX knowledge base. It appears across the Knurture Protocol corpus as a lens for understanding user behavior, product strategy, and design decisions. Dominant Force shapes how product teams think about progress, switching, and adoption. It connects to other JTBDUX concepts in ways that create actionable guidance: when combined with the Four Forces, it explains why users stick or switch. When combined with job stories, it reveals what to build. When combined with measurement, it shows what to optimize.
