Primary Metric(s) - Meaning and its Characteristics
In order to truly control a process, one must understand the inputs as well as outputs of the process. These inputs and outputs are displayed through numbers which are called metrics. The primary metric is a way to say with numbers how well your process is performing. Here are a few pointers that will help understand the concept of primary metrics in detail.
What is a Primary Metric ?
Any process can be defined as Y = f(x) where Xs are the critical inputs. The output here is Y. The primary metric of a process is the Y of that process, meaning an output of the process under consideration. The state of the output needs to be consistently measured, errors must be spotted and correction must be immediately made. It is therefore of vital importance for a Six Sigma project to identify the correct primary metrics. This ensures that the project is in control. Choosing the wrong primary metrics will create a situation wherein the wrong thing is being measured. This focuses the organization in the wrong area creating colossal losses in the long run.
Traceable to Critical to Quality Measures
The primary metric does not appear in this stage. It has been present in the project since the first step. The primary metrics have their roots in the critical to quality measures defined by the customer. The get recorded in the problem statement, goal statement and business case. Then they are formally chosen as the primary metric if the project is being correctly executed.
