Why is it important to establish a baseline in a Six Sigma project?

Establishing a baseline in a Six Sigma project is crucial because it provides a point of reference against which any improvements can be measured. The baseline represents the current level of performance or capability before any changes are implemented. By having this initial measurement, teams can quantify the extent of improvements made as a result of the project.

Without a baseline, it would be challenging to determine whether the changes introduced have had a positive impact, remained unaffected, or even worsened the situation. This quantitative measure is vital for tracking progress, validating the effectiveness of implemented solutions, and demonstrating the actual benefits realized from process improvements to stakeholders. Ultimately, it plays a key role in the continuous improvement cycle fundamental to Six Sigma methodologies.
