As far as Six Sigma methodology is concerned, there is a wide spectrum of it on the basis of its diverse aim. Not only Cost savings and Quality improvements but also pricing and designing modern products and services Six Sigma can deal with.
Among many others, DGMAIC approach is regarded as the most significant since it is of great assistance in identifying and solving complicated problems by dint of adopting Six Sigma. One of the major methodology applied for new products is so-called DMEDC which abbreviation stems from the cluster of Define - Measure- Explore - Design - Control.
If it comes to designing products Six Sigma uses the DMADV approach which abbreviation is derived from Define - Measure - Analyze - Design - Verify. Nevertheless, it is vital to apprehend the methodology and to go through the entire cycle without taking any shortcuts. It is typical of each methodology in Six Sigma to examine data and perform cardinal analysis prior to introducing changes and maintaining constant control over the result.
However, Six Sigma not only lead to improvement in existing structure but also handle successfully with problems. In addition to this, Six Sigma enhances development of new products or processes with a view to assuring outstanding quality standards of its outcomes. Because of the fact that 25% to 40% of new products end in failure, it is vital for the companies to ensure that resource allocation in new product development result in suitable returns. In general, although DFSS enhance the success for designing and implementing of new products, its set - up differs among companies depending on individual organizations and products. DFSS ensures customers that the design and quality of new products fulfil their demands. The manufacturing process and After - Sales - Services are the focus of attention referring to timing and input to the net profit to the company. Design, material, labor and overhead costs are taken into consideration for improvements.
Six Sigma pass practical problems to statistical data and as a result determine functional solution with the aim of reducing opinion and uncertainties. Thanks to a statistical data approach problems impacts and solutions appear to be measurable and the evaluation is facilitated.
It is a common knowledge that companies frequently pay attention to value either of performance or outcome. Therefore, they give little consideration for variation of the process in spite of the fact that is of tremendous importance for the quality. Six Sigma provide focus on the variation that demands greater analysis and gives better insight and effects as well.
To sum up, Six Sigma is a tool, methodology and culture which pose a difference in Quality and Process Management (Top - Down Approach) in a company. The introduction of the culture needs solid support received from Senior Management so as to assure structures, resources and training. Each employee has to accept and apply the methodologies, tools and ideas simultaneously (Bottom - Up Approach). Each stakeholder alters in mindset and pays attention to quality, data analysis, process orientation and variations. It is also focused on slowing down the decision process, finding time for analysis and comprehension of a problem rather that following either quick solutions or blind actions (by trail and error Management).
