We are qualified and have extensive knowldege in implementing six sigma tools in our organization.
Six Sigma (6S) is a customer focused, data driven methodology for achieving breakthrough and continuous improvements in the business, service process and their designs in order to provide near perfect services. The word "Sigma" is a statistical term that measures how far a given process deviates from perfection. The idea behind six sigma is, in measuring six such standard deviations between the mean and the nearest specification limits in any process, to enable us to systematically figure out how to eliminate them and get as close to "zero deviation" as possible.
Six Sigma Advantages
- help better understand client requirements
- helps design service processes that meet desired quality levels
- helps in measurements of process performance parameters.
- helps in continuous process quality improvements in transient environment.
- helps in reducing process variations
We use two methodologies for six sigma, DMAIC and DMADV
DMAIC is used to improve an existing business process. DMADV is used to create new product designs or process designs in such a way that it results in a more predictable, mature and defect free performance.We use DMADV in six sigma consulting work.
DMAIC
Basic methodology consists of the following five steps:
- Define the process improvement goals that are consistent with customer demands and enterprise strategy.
- Measure the current process and collect relevant data for future comparison.
- Analyze to verify relationship and causality of factors. Determine what the relationship is, and attempt to ensure that all factors have been considered.
- Improve or optimize the process based upon the analysis using techniques like Design of Experiments.
- Control to ensure that any variances are corrected before they result in defects. Set up pilot runs to establish process capability, transition to production and thereafter continuously measure the process and institute control mechanisms.
DMADV
Basic methodology consists of the following five steps:
- Define the goals of the design activity that are consistent with customer demands and enterprise strategy.
- Measure and identify CTQs (critical to qualities), product capabilities, production process capability, and risk assessments.
- Analyze to develop and design alternatives, create high-level design and evaluate design capability to select the best design.
- Design details, optimize the design, and plan for design verification. This phase may require simulations.
- Verify the design, set up pilot runs, implement production process and handover to process owners.
