Technology Acceptance Model (TAM)

1. TAM: A Model for Predicting Technology Adoption and Analyzing Acceptance

    A["Uncertainty in technology adoption"] -- "Predicting actual use" --> B["TAM (Technology Acceptance Model)"]
  

Core: A model that predicts actual use by analyzing a user’s technology acceptance process centered on “perceived usefulness” and “perceived ease of use.”

Characteristics:
(Key factor analysis) Analyzes the two key variables influencing technology acceptance: perceived usefulness and perceived ease of use.
(Predicting attitude and behavior) Predicts a causal path from external variables → usefulness/ease of use → attitude → behavioral intention → actual use.

2. TAM Acceptance Analysis Model and Strategic Framework

A. Perceived Usefulness

(The belief that using the technology will improve job performance)

• Performance improvement: How much a given system improves the speed or accuracy of task completion.
• Effectiveness: The extent to which the technology contributes to achieving organizational goals.

B. Perceived Ease of Use

(The belief that using the technology requires no effort — a strategic mechanism)
