Figure 5 illustrates the bow-tie analysis of
another consequence of the incompetent
management
the bungs were driven in too early in the
process, which had serious consequences for
later stages.
This shows that the reason for driving the bungs
early was quite reasonable – but also that there
was no adequate process analysis.

Figure 6 illustrates that pile driving
came too late in the process, with the
result that other process stages, e.g.
laying the crane tracks, occurred
before the piles were cut, with
consequences for the pile cutting.

It was also possible to clarify the
link between deficient electrical
planning and a number of critical
events later in the construction
phase during the internal fitting
out.
