2.2. The successes and shortcomings of the implementation of Six Sigma
The reason for the implementation of Six Sigma and its basic methodology DMAIC is finding quality basic data
and knowledge of the right indicators that form the basis for planning the levels of Six Sigma. The creation of
measurement and evaluation infrastructure that monitors ongoing changes in the performance of processes, with
respect to customers and their requirements as indicated by Pande et al. (2002), is the basic building block of a
functional system of Six Sigma. The advantage of this structure is a fast reaction to changes in the processes if they
do not fulfill the requirements, if the causes of the problem are not clearly identified or if we cannot remove the
causes of the problem.
