Priority Assessment Techniques Project Phase 2: Comparison of Scheme Rankings Using Six Priority Assessment Techniques

This paper presents and analyses the results of a quantitative comparison of six priority assessment techniques (PATs) using a sample of six schemes. The PATS were selected as a representative sample of those currently in use in the UK (see Working Paper 230 and Technical Note 190).

The results reveal significant differences in the project rankings between techniques, although these are reduced when problem, solution, or problem and solution oriented PATs are considered separately. The proportion of points allocated to particular objectives for individual schemes varies widely between PATs. Greater standardisation would probably be desireable.
