The diagram shows a sequence of connected boxes with arrows. On the left a box labeled External Variables points to two boxes. The first box is Perceived Usefulness with the letter U. The second box is Perceived Ease of Use with the letter E. Perceived Ease of Use points upward to Perceived Usefulness. Both Perceived Usefulness and Perceived Ease of Use point to the next box labeled Attitude Toward Using with the letter A. This box points to the next box labeled Behavioral Intention to Use with the letters B I. Behavioral Intention to Use points to the final box labeled Actual System Use. An additional arrow goes directly from Perceived Usefulness to Behavioral Intention to Use.TAM model (Davis, 1989).
