This study has also identified specific critical planning processes in construction
projects. “Activity definition” has been found to be the most critical planning process
for the construction sector, significantly influencing project success. Hence, a
construction project manager should spend more effort identifying project activities.
This can be done by using one of the tools described in the project management
literature, e.g. subdividing the work breakdown structure (WBS) work packages into
more detailed activities (PMI Standards Committee, 2004). Development of a project
plan has been found as another critical planning process in the construction sector.
Construction project management training programs should place greater emphasis on
planning. Construction organisations should support their project managers with
proper assistance in this area. In doing so, construction projects may achieve better
results in all success dimensions.
