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!

The Pareto Priority Index or PPI is a method of performing a cost to benefit analysis. It is used in quantifying potential projects. The analysis weighs the savings and probability of success against the cost and time of completion. It is important to keep in mind that unless historical data is gathered and used the index is largely qualitative and often includes no customer input. When prioritizing your project options it is a good idea to take into consideration customer surveys and other qualitative means before final project selections are made.
Qualitative gives reference to the use of "qualities" rather than "quantities." Qualitative data and analysis is subjective and is used mostly in circumstances where data is not easily accessible, not relevant or simply not available for use. Qualitative research is largely based on experience, feelings and intuition.
