| Tiivistelmä≠ | The Technology Acceptance Model 2 (TAM2) was developed by Davis and Venkatesh in 2000 and published in Management Science. TAM2 extends the original TAM by incorporating social influence factors and job relevance moderators that explain how users form perceived usefulness beliefs. TAM2 is grounded in longitudinal field studies across multiple organizational contexts and systems. | The Technology Readiness Index (TRI) was developed by Ajay Parasuraman in 2000 to measure individual propensity to adopt and use new technologies. The TRI assesses a person's personal attitudes toward technology across four dimensions: optimism, innovativeness, discomfort, and insecurity. Updated in 2015 with a streamlined 16-item version, the TRI helps identify technology adopter segments and predict behavior across diverse technology contexts. |
