The Affinity Diagram is a powerful tool to use during projects with team members. It is an analytical tool that teams can use to organize ideas into subgroups with a common theme or relationship. The affinity diagram can help you see correlation in large amounts of data/information. It was created by Jiro Kawakita. There are many different methods that practitioners use to develop or build the affinity diagram. In 2015 Lean Strategies International LLC created the ©CURE methodology, which is a simple four step methodology that teams can use to group large amounts of data, establish innovative ideas and find solutions to issues while getting the most out of opportunities. The four steps for our upcoming course on the ©CURE methodology are shown below.
The name A3 is actually a reference to the size of paper the report is placed on. This report collects all key pieces of information and allows users to review all elements of improvement events, kaizen events and initiatives on one piece of paper. From a philosophical standpoint A3 refers to a thinking process used by many lean and six sigma practitioners for solving problems or taking advantage of opportunities. The thought process is outlined shown on the A3 and helps users establish a standard method of thinking while indirectly creating a familiar language and method of thinking amongst people. To learn more about A3 thinking visit a recent post in our blog Listen to the Gemba titled The Size of your brain matters not, A3 will fit!
What is your experience?
Have you used an A3 document in an improvement event before? If so, we would love to here what your experience was like.
In both lean and six sigma it is important to understand all aspects of waste, including inventory. One form of inventory is anticipation inventory. Anticipation inventory is built according to "anticipated" or some future demand. It is additional inventory that is created above and beyond the actual demand of customers according to forecasts, projections or trends. Some examples of anticipation inventory might be:

ABC classification or ABC analysis is a technique used in materials management. The ABC represents the different categories of inventory in your system and indicates the level of control each category requires. The Apics Dictionary 2015 edition defines the categories of the ABC system as:
A = The A group usually represents 10 percent to 20 percent by the number of items and 50 percent to 70 percent by projected dollar volume.
B = The B grouping usually represents about 20 percent of the items and about 20 percent of the dollar volume.
C = The C grouping usually contains 60 percent to 70 percent of the items and represents about 10 percent to 30 percent of the dollar volume.
It is important to note that there is no fixed numbers for each category. Each organization should customize their classification system based on a pareto analysis.
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.
