Method use in practise
Low acceptance of third-party (commercial/text-book) methods:
- 26% use formal methods (Fitzgerald 1995)
- 40% use methods (Fitzgerald 1995)
- 62% use a structured approach (Necco et al. 1987)
- 66% use methods frequently (Russo et al. 1996)
- 82% use methods (Hardy et al. 1995)
- Selected sample, definition of method and the actual question explains differences among results
Paradox: if methods are considered feasible, why are they not used systematically?
