1. The predictability of design and construction cost seems to be quite accurate
since the means of the cumulative values represent zero and one percent
respectively. However, the productivity value is very low. Does this mean that
the predicted costs are over estimated to cover low productivity or the measures
used to derive the figures are wrong?
2. The client satisfaction in terms of the product and service is quite high (eight out
of ten) but the productivity is very low which raises the issue of: do the clients
really know what the productivity levels of their projects are?
