Deciphering the Six Sigma Acronyms; DMAIC, DFSS, DMADV, DMADOV, DCCDI, and IDOV

Most times, when a person brings up the subject of Six Sigma, it is never understood well.  It is a complex process that is easier to understand when broken down into basic steps. These steps include; define, measure, analyze, improve and control procedures.

The DMAIC Process (Define, Measure, Analyze, Improve, and Control) is used for improving any business’ current product or process, which may be failing to satiate customer desires. DFSS - Design for Six Sigma is remarkably different from DMAIC as it is solely used to make new products or a process that meets customer desires. Compared to DMAIC, which is applicable on any business procedure, DFSS concepts and systems do not have as much general recognition.

These processes differ from company to company dependent on the fundamental features of a business product procedure that requires development. Therefore, DFSS may either be implemented for enhancing the work culture in a business or for helping in the placement of the other Six Sigma ideas which are being practiced by rivals. Indeed, this makes it a more feasible methodology, rather than an individual optimization procedure like DMAIC.

The DFSS, or Design for Six Sigma, approach is applicable only in situations where a new product or a business procedure necessitates designing or upgrading from scratch. Therefore, it aims at lowering defects to less than 3.4 per million opportunities. Moreover, maintaining such high level of quality from the onset will require Six Sigma specialists to have a high degree of comprehension about customer wants and specifications, before any completion or implementation of a design.  This is done through market research and data collection.

DFSS has numerous variations, which perform matching basic functions but are employed in diverse business procedures. This variation is also known as DMADV, which means define, measure, analyze, design, and verify. In the define stage, the detailed needs of the customer is defined based on data collected through investigation. These needs are then scaled, and bench marked, based on competitors or industries that are already satisfying such wants.  The next step looks at the scrutiny of the available process options that can be employed for satisfying the bench marked client requirements. Therefore, the most proper procedure is then picked dependent on the cost effectiveness of the process. This allows for smooth enactments of any method preferred.

In the final stage, the selected practice goes to verification for its performance and capability to meet the exact client needs. However, DMADV has its own disparity that is known as DMADOV, which stands for, define measure, analyze, design, optimize, and verify. It is abundantly clear that from the definition of DMADOV that there is just one extra step, this is optimization, which could be beneficial for some business procedures.

The other difference of DFSS is the DCCDI. This stands for Define Customer Concept, Design and Implement. However, it has many similarities and overlaps with the DMADV process like define, measuring, and the design stages. Therefore, the stage of enactment is the only addition to this procedure that is connected to the creation and commercialization of a good or service.

IDOV is also another difference of DFSS and stands for identity, design, optimize and verify. This method also has just one addition, which is optimization. Therefore, corporations can device any of these methods in satisfying their necessities and the input given by knowledgeable Six Sigma experts.
