Résumé	The DeLone and McLean (D&M) Information Systems Success Model, introduced in 1992 and refined in 2003, provides a comprehensive framework for evaluating information system effectiveness across six dimensions: system quality, information quality, service quality, use, user satisfaction, and net benefits. Unlike acceptance models that focus on adoption intention, the D&M model measures actual realized benefits and organizational impact.	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.
