Eskom, South Africa’s leading energy...

Eskom, South Africa’s leading energy
utility, wanted to find new ways to
streamline processes and cut costs,
especially important during times of
economic uncertainty. In particular,
managing almost 40,000 people
and their pay was a demanding
task. The complexity of supporting
multiple legacy applications and
server platforms hindered progress,
which was reflected in slow monthly
financial consolidation and difficulties
in gaining an enterprise-wide view
of budget and performance from
different business units.
