Pareto analysis is a very simple technique that helps a manager to choose the most effective changes to make. It is represented as a bar graph used to arrange information in such a way that priorities for process improvement can be established. Pareto charts are constructed to provide a before-and-after comparison of the effect of control or quality improvement measures. The Pareto Effect The 80:20 theory was first developed in 1906, by an Italian economist, Vilfredo Pareto, who observed an unequal distribution of wealth and power in a relatively small proportion of the total population. This fact gave rise to the Pareto effect or Pareto’s law: a small proportion of causes produce a large proportion of results. Thus frequently a vital few causes may need special attention wile the trivial many may warrant very little. It is this phrase that is most commonly used in talking about the Pareto effect Continue reading

Goldratt’s Theory of Constraints – Constraint Management
An Israeli physicist, Eliyahu Goldratt wrote a book titled ‘The Goal’, about a factory manager’s quest to save his factory from being closed down for lack of profitability. It chronicles the process that the manager and his staff go through as they learn how to save their factory. What they learn is how to apply the principles of what Mr. Goldratt calls the “Theory of Constraints.” Theory of Constraints (TOC) is a logic-driven approach which focuses on system improvement. The core idea of TOC is that every organization has at least one constraint that prevents management from achieving the goal of the organization to a larger degree. A system can be defined as a collection of interrelated, interdependent components or processes that act in concert to turn inputs into defined outputs in pursuit of a particular goal. Linking systems to chains, TOC defines weakest link as a Constraint. Constraint limits Continue reading
Total Quality Management (TQM) Approach
Quality is a continuous process that can be broken anywhere in the system of supply and customer service. By letting every person know how their activities help fulfill customer’s requirements, the organization can motivate their employees and supplies to provide quality consistently. They must also realize that throughout the organization they will have both internal customers and’ supplies to those outside the organization. In general, a process helps to change a set of inputs into desired output in the form of products or services. Proper investigation of the inputs and outputs of the organization help to determine the action to be taken for the improvement of the quality. The quest for continuous improvement of quality is a continuous cycle. The process on which continuous improvement is based is generally known as “Deming Wheel“. The wheel represented below shows a continuous movement in a certain direction. The idea behind this that Continue reading

Order-to-Cash Process – Meaning and Steps
Order-to-cash process consists of financial transactions with the customers in a supply chain. Order-to-cash process starts with the customer placing the order and ends with receiving the payment from the customer. The steps involved in the order-to-cash process are explained below.
