Non-Value added activities are any activities that add no value to the product or the service.  Non-value added activities do not transform the product, process or service, nobody is willing to pay for the activity or they are not performed correctly the first time through.   Non-value added activities take up about 85% of the Value Stream in organizations.  For more information on how to identify and remove non-value from your organization enroll in our course on waste.

  The nomogram is a computational aid which consists of two or more scales which are drawn and arranged so that results of calculations may be found by the linear connection points.  The graph usually contains three parallel scales graduated for different variables so that when a straight line connects each value of any two, that value can be read directly from the third at the point of intersection.

Also Called: Alignment Chart

    ​Normal distribution is a statistical representation where most distributions that are observed are relatively close to one mean (average).  If there is deviation associated with the mean, which there normally is, the deviation remains almost identical on the plus side as the deviation on the minus side.  When normal distribution is graphed (histogram) it generally takes the shape of a bell showing "normal" or even distribution from the mean.
