4.1(iii) Measurement of PIE-Index
The measurement of the PIE-Index involves three steps. (i) The first step is to put the 9
main-variables and 40 sub-variables into the multi-input-output table. (ii) The second
step is to evaluate sub-variable by sub-variable according to the parameters mentioned
above. (iii) The third step is to calculate the value of each main-variable. This value is the
sum of all sub-variables (of the particular main-variable) divided by the total number
of sub-variables (see Expression 1). The last step is the actual measurement of the PIE-
Index. The PIE-Index is equal to the sum of all main-variables (see Expression 2) .
4.1(iii)(a)Evaluation of Consistency of PIE-Index
The PIE-Index can be used to evaluate the level of consistency of any policy modeling.
The PIE-Index is classified according to one of these four levels of research consistency:
‘perfect policy consistency’; ‘good policy consistency’; ‘acceptable policy consistency’;
‘low policy consistency’. If the PIE-Index is between 1 and 0.90 points, then the
research is of ‘perfect policy consistency’. If the PIE-Index is between 0.89 and 0.70
points, then there is ‘good policy consistency’ in the research. A PIE-Index that is
between 0.69 and 0.50 points shows ‘acceptable policy consistency’ in the research.
If the PIE-Index is between 0.49 and 0 points, then we are referring to a ‘low policy
consistency’ research.
4.1(iii)(b) Construction of Policy Implementation Effectiveness Surface
(PIE-Surface)
The full implementation of the PIE-Index requires one fourth step, that is, the
construction of the PIE-Surface. The purpose of constructing the PIE-Surface is to
graphically represent all results in the PIE-Matrix. The PIE-Surface shows the strengths
and weaknesses within any policy modeling on a multi-dimensional coordinate space
(Ruiz Estrada, 2011). (see Figure 1). The construction of the PIE-Surface is based on
the PIE-Matrix results (see Expression 3). The PIE-Matrix is a three by three matrix
that contains the individual results of all nine main-variables (taken from Table 2). The
idea here is to use the results of strictly nine main-variables in the PIE-Matrix to build
a symmetric surface. When the PIE-Matrix keeps the number of rows strictly the same
as the number of columns, then the PIE-Surface can always show a perfect symmetric
view (see Table 3).
