A Six Sigma control chart can be employed to analyze the Voice of the method (VoP) firstly of a undertaking to find out regardless of whether the method get more info is steady and predictable. This really helps to recognize any challenges or possible challenges that could occur throughout the project, permitting for corrective action to generally be taken early on.
