 note = {Prior research suggested that principal component analysis was effective as an
alternative assessment technique in terms of clarity of reasons for selecting the most suitable
option, low arbitrariness, verification of analysis results and easiness of technique. This study
aimed to apply this analysis to the 15 cases of alternative assessment that the Japan
International Cooperation Agency prepared, in order to verify the adequacy of a regular
assessment methodology. Some options selected were the same as options selected by regular
techniques and other options were different. The reasons would be criteria setting with a high
correlation, arbitrary weighting and evaluation, and summation using scores not normalized.
The principal component analysis could deal with the above-mentioned problems and be a
recommended alternative assessment technique and a preferable number of alternatives and
criteria could be six and ten at the minimum. Finally, this paper proposed to use this analysis
as a second assessment technique to verify the result of an alternative analysis with
summation using normalized scores. Further case studies are required to find an appropriate
alternative assessment methodology including public involvement and establishing correct
criteria and right alternatives.},
