Is variability in your process, a problem?

Are you experiencing variations, and is that the one big ticket you are working towards?

Let me help you bring in terms with the reality.

Variation or say variability is part of every process and it isn’t the aim of your process to eliminate them.

In fact, you cannot eliminate them either (may be you experience an expectation mismatch, and that could be the root of all your worries with the process).

Now if you getting this bit clear, but still wondering why you need a process, here comes the answer for that.

You need a process not to eliminate variation (which no one can) instead to understand variation.

Note: Günter Wagner et al. (1997) have made this distinction explicitly, defining variation as the set of observed differences and variability as the tendency of a system to generate differences. The distinction, therefore, is one of pattern versus process.
