Understanding Sigma Levels
What Is Sigma ? Sigma or standard deviation is a statistical measure of dispersion in data. It is a measure which uses the characteristic of past data to make judgements about how the process will perform in the future. If a given set of data has normal probability distribution then the number of defects that […]
Inventory Control – Inventory Audits and Cycle Counts
Any inventory of Raw materials, finished goods as well as Intermediate in process inventory has an economic value and is considered an asset in the books of the company. Accordingly any asset needs to be managed to ensure it is maintained properly and is stored in secure environment to avoid pilferage, loss or thefts etc. […]
What is Due Diligence, Why it is Important, and How it Works and, What it Does ?
What is Due Diligence? Many of us would have heard the term Due Diligence in various contexts and situations where one party to a transaction often tells the other to do their due diligence or states that it is considering the same. Indeed, as anyone who has negotiated an employment contract or a legal drafting […]
Understanding Root Cause Analysis (RCA)
Imagine your company’s biggest client calls with a complaint about product defects. This isn’t the first time and if we’re being honest, you’ve ’fixed’ this issue more times than you care to count. Each time, it feels like you’re putting a Band-Aid on a bullet wound, hoping this time will be the fix that keeps […]
The Problems with Protectionism
The world seems to have turned on its head. Countries like the United States and the United Kingdom were earlier frontrunners in the race for globalization. They were increasingly pressurizing developing countries to open their markets. They thought this would allow them to have increased sales for their products. They never thought the reverse could […]
The final step in the metrics is to measure the financial benefits that are accruing to the firm because of the Six Sigma project being undertaken. This is important and is also an area of concern. Most criticisms of Six Sigma say that the benefits that are presented in such analysis are incorrect and actually do not accrue to the firm. They claim that the true picture of the projects is often different.
However, to get the resources sanctioned from the finance department, it is essential that the Net Present Value (NPV) of the project be presented to them. The most common category of gains that accrue to an organization because of six sigma projects is as follows:
Increased Revenue: The most obvious benefits of the six sigma project would be an increase in revenue. This could be driven by many factors.
With more efficient processes, the firm may be able to produce goods more cheaply than others and hence sell more increasing revenues. Or with the help of six sigma projects, the firm could increase the quality of its products increasing customer loyalty and adding to revenues.
Avoided Costs: The firm can avoid many costs in the form of regulatory penalties, expansion costs etc, if its processes are efficient.
Let’s assume that a factory manufactures 100 cars. If by efficiently redesigning the processes, the factory can now manufacture 120 cars, then the fixed costs of manufacturing those 20 cars have been avoided. Governments sometimes penalise inefficient behaviour in companies.
For instance if the company does not pay its taxes on time, it has to pay penalties. Six sigma projects can make these processes efficient and avoid such costs for the management.
Reduced Costs: The operational costs of the firm can be drastically reduced with the help of six sigma projects. With the help of Six Sigma, Motorola was able to offer pagers which were much better in features than the competitors at a price which was much less than that of the competitors.
Non-Monetary Benefits: There are several non-monetary benefits that accrue to the firms as well. In many cases these translate into indirect monetary benefits. However since they cannot be precisely measured they must be called non-monetary. Common examples of such benefits are as follows:
Critics of six sigma say that analysts use fuzzy numbers and double counting to increase the NPV of the projects in question. However there is no doubt about the fact that efficiency has never harmed an organization.
Undertaking six sigma projects and completing them efficiently will only make the organization better off.
