ABSTRACT
It is possible for a project to be completed on schedule and within budget and still not be considered a success. The reason is simple: quality. If the quality does not meet the customer’s expectations, nothing else matters. Although many project managers focus heavily on schedule and budget, quality is sometimes relegated to a secondary role. However, it is such an important aspect of project management that Morris and Sember consider it one leg of what they call the “iron triangle,” their version of the project constraints triangle shown as Figure 1.1 that has cost, schedule, and quality as its components.*
While it is arguable whether quality should replace scope as a primary project constraint, few would dispute the importance of quality, and certainly not a Six Sigma company with its emphasis on quality as the way to attain customer satisfaction. That is why quality measures form an integral part of every Six Sigma project and why they should be included in all projects, not simply those initiated by Six Sigma companies.
