173 6.2.4 The Comprehensiveness of the Housing Forecasting Activity The comprehensiveness of the SP’s housing forecasts, and other plans as well, very much depends on the type of forecasting technique applied, elements that are considered, time-frame and the final outcomes (Field and MacGregor, 1987). These factors, as discussed earlier in section 3.3.2.2 and section 4.9.1, are used as criteria to measure the comprehensiveness of housing forecasts for the study area’s SPs.
6.2.4.1 The Application of Housing Forecasting Technique As mentioned in section 3.3.2.2, there are three techniques, from an integrated to a common and simple one, that can be applied to forecast future housing requirement. The analysis done shows that all three techniques are variously applied in the study area’s SPs. Out of seven SPs, five applied the common forecasting technique, while one, i.e. the MPJB (First Alteration) SP applied a simple forecasting technique. Only the MPJB, Mukim Plentong and Pasir Gudang SP used an integrated technique to forecast future housing requirement for its area (Table 6.3).

6.2.4.2 The Aspects Considered in Forecasting Future Housing Requirement In line with the techniques used, only the MPJB, Mukim Plentong and Pasir Gudang SP incorporates all figures, such as the housing aspects, future household
