Summary:
This paper looks at the area of software measurements for software models. The authors notice that software measurement has been widely accepted by academics but has had much less success within industry. Furthermore the model driven design paradigm has developed several approaches for fully automated software measurement tools for early stage models.

The authors conduct an experiment using the Technology Acceptance Model to investigate a set of factors that affect practitioners' perceptions. Specifically the experiment analysed the affect of influences (perceived ease of use, perceived usefulness, and intention to use) for acceptance of RmFFP, a measurement procedure designed to automatically estimate the function size of object-oriented applications generated in an MDA environment.

The experiment was conducted used 20 participants, all of whom where Professors in Software Engineering. The experiment used regression testing to showed the following hypotheses as either confirmed (C) or not confirmed (NC):
1) C - Perceived Usefulness is determined by the quality of results of the RmFFP measurement procedure.
2) NC - Perceived Usefulness is determined by the tangibility of results of the RmFFP measurement procedure.
3 C- Perceived Usefulness is determined by job relevance using the RmFFP measurement procedure for the software practitioner.
4) NC- Perceived ease of use is determined by the minimum number of actions required using the RmFFP measurement procedure.
5) C - Intention to use is determined by usefulness perceived.
6) NC - Intention to use is determined by perceived ease of use.
