Parameters listed in Table 4 are rated as following:
| O = | not suitable, if the factor does not conform within the range of acceptable levels set for that parameter. |
| M = | marginal, means that the quality of this factor is, or could be made acceptable, but that it has a low rating otherwise. |
| A = | acceptable, indicates average values. |
| G = | Good i.e., the values obtained for this factor are better than average. |
The evaluator must now take into account the “Present state” and
“Future development” conditions to arrive at a final
“Suitability” rating for each category item. A final evaluation
can be made by resolving all of the foregoing individual ratings
into the three categories, namely, not suitable, marginally
acceptable and good
(Table 5).
