What is the difference between Six Sigma and...
Meaning of Six Sigma
Six Sigma is a:
* A Quality Philosophy. It's a philosophy that talks about attainable short-term goals while striving for long term objective.
* A Tool. Six sigma is a statistical and problem solving tool.
* A Management Strategy or a Business Process. That allows companies to design, operate, control and monitor everyday processes.
* A Concept or an Idea. Which has to be first understood and then merged into the organization's culture.
* A Process. Business revolves around processes. A process is any activity or group of activities that takes an input, adds value to it, and provides an output to an internal or an external customer. Six Sigma provides it's inputs in the form of measurements of the company's existing set standards, working on them to get the desired output i.e.; less number of defects and higher quality.
* A Measurement. Of total quality as well as the defects that might have been overlooked till now.
Applicability of Six Sigma to the organization
? Process improvements;
? Product and Services improvement;
? Supplier improvement;
? Design Methodology;
? Training and improvement.
Thus Six Sigma is a long-term, forward-thinking initiative designed to fundamentally change the way corporations do business.
It is first and foremost "a business process that enables companies to increase profits dramatically by streamlining operations, improving quality, and eliminating defects or mistakes in everything a company does".
Six Sigma tells you:
? Your don't know what you don't know
? You can't do what you don't know
? You don't know until you measure
? You don't measure what you don't value
? You don't value what you don't measure
Role required by the organization:
? Executive Leadership- Responsible for setting up a vision for Six Sigma implementation.
? Champions - responsible for the Six Sigma implementation across the organization in an integrated manner
? Master Black Belts, identified by champions, act as in-house expert coach for the organization on Six Sigma. They devote 100% of their time to Six Sigma. Black Belts operate under Master Black Belts to apply Six Sigma methodology to specific projects.
? Green Belts are the employees who take up Six Sigma implementation along with their other job responsibilities. They work under Black Belts
Biggest impact to the organization will be in operations and profitability, it will help in:
? Six Sigma helps the organization to achieve improved process flows and better communication. There is decreased Work-in-Progress and Cycle time for every activity/process is reduced.
? With Six Sigma an organization has enhanced productivity thereby resulting in better services by the organization
. ? Reduction in total number of defects in any activity is the main thrust of Six Sigma therefore we get better quality services which contribute straight to the bottom line.
? Since we have better quality thus we have reliable products that again contribute straight to the bottom line and not to mention the elevated image the company gains.
Benefits to stakeholders (shareholders, customers, suppliers, employees):
Six Sigma begins by measuring the statistical variability within a process. It means plus or minus six standard deviations, which translates down to 3.4 errors per million occurrences. Six Sigma processes are designed to reduce process variability. Thus six sigma will help in reducing defects and applied it to every business process of supply chain.
? Shareholders end up receiving more profits (dividends) due to millions of dollars of additional savings per year.
? Customers are delighted with, now, higher quality products and services.
? Suppliers are able to supply higher quality inputs. (Otherwise also they are pulled up and asked to get rid of their complacent attitude as the case may be).
How would DFSS be applied to your supply chain operations?
Supply chain means:
"A supply chain is a network of facilities and distribution options that performs the functions of procurement of materials, transformation of these materials into intermediate and finished products, and the distribution of these finished products to customers. Supply chains exist in both service and manufacturing organizations, although the complexity of the chain may vary greatly from industry to industry and firm to firm." By Terry Harison.
It has following three components:
(1) Demand Fulfillment?The objective of the demand fulfillment process is to provide fast, accurate and reliable delivery-date responses to customer orders. Demand Fulfillment is mainly an execution-level sub-process that includes order capturing, customer verification, order promising, backlogs management, and order fulfillment.
(2) Demand Planning?The objective of the demand planning process is to understand customers' buying patterns and develop aggregate, collaborative forecasts. Demand planning is by definition a planning process, which feeds into the supply planning process, and subsequently the demand fulfillment process. Demand planning involves long-term, intermediate-term and short-term time horizons.
(3) Supply Planning?The objective of the Supply Planning process is to optimally position enterprise resources to meet demand. This is a planning-level sub-process that spans the strategic and tactical supply-planning processes. Long-term planning, inventory planning, distribution planning, collaborative procurement, transportation planning and supply allocation are all part of this sub-process.
The major challenges of supply chain management are:
? Making products or services available in a cost-effective manner with the desired quality.
? Making sure information is available easily to run the supply chain.
Six Sigma tries to reduce the value of this Sigma i.e., the value of this variation by decreasing the number of original defects in the product. This can be done by reengineering the process so that there is a higher level of specification limits; for example if the previous specification limit was X+-3Sigma then now it can be X+-6Sigma because the value of deviation i.e., Sigma (variation) has been reduced by decreasing the number of defects in the original product.
Thus six Sigma begins by measuring the statistical variability within a process. It means plus or minus six standard deviations, which translates down to 3.4 errors per million occurrences. Six Sigma processes are designed to reduce process variability. Thus six sigma will help in reducing defects and applied it to every business process of supply chain. It will help in from procurement of raw material to a distribution of finished product and all the way to billing and collections after the product is delivered. It will help in uncover new ways to harvest cash as it will reduce cycle times, lower ...
