process that strives for near perfection. Six Sigma seeks to improve the quality of process
outputs by identifying and removing the causes of defects and minimizing variability in
manufacturing and business processes (which explains why only 3.4 defects per 1 million
units are bearable to a company practicing Six Sigma). The doctrine associated with Six
Sigma proclaims that continuous efforts to achieve stable and predictable process results
are of vital importance to business success. The doctrine also states that manufacturing and
business processes (where the emphasis of this report lies) have characteristics that can be
measured, analyzed, controlled and improved. The most important aspect of the Six Sigma
doctrine is the assertion that achieving sustained quality improvement requires
commitment from the entire organization, particularly from top-level management.
Although Six Sigma quality follows two types of methodologies inspired by Deming’s
Plan-Do-Check-Act Cycle, only one will be discussed in this report. The methodology
used in this report is the DMAIC, which is the most common used in business systems. D
stands for defining the system, M stands for measuring the key aspects of the current
process, A stands for analyzing the data to investigate and verify cause-and-effect
relationships, I stands for improve the current process based upon the data analysis, and C
stands for control. In this report, we will focus on how financial systems have
implemented Six Sigma and how successful these systems have become
post-implementation. This will further show that Six Sigma quality should be a goal for all
business systems due to its proven reliability.
