I foresee a bright future as I will gain more skills and knowledge in the domain of lean and six sigma management by adding new technologies as needed by my organization for being competitive after considering the strengths, weaknesses, opportunities and threats of the organization.
Q.14 What is the difference between Cpk and Ppk?
Cpk is process capability index and it measures how close a process is running to its specification limits, relative to the natural variability of the process. Ppk is process performance index which verify if the sample has been generated from the process is capable of meeting customer's critical to quality (CTQ) requirements or not.
Q.15 What do you understand by MSA?
MSA or Measurement System Analysis is used to assure that a selected measurement system delivers reliable results with repeatability and reproducibility. MSA evaluates a system’s accuracy, precision, and stability.
Q.16 What do you understand by SIPOC?
SIPOC or Suppliers, Inputs, Process, Output, and Customers, is a visual tool which documents a business process from beginning to end before implementation. SIPOC is usually used in the “define” phase of the DMAIC methodology.
Q.17 What is the utility of an F-Test?
An F-Test in six sigma is used for testing the variance and only when sub groups are small.
Q.18 What is a chi-square Test?
The chi-square Test is a statistical tool used to test independence or dependence (or goodness-of-fit) between random variables taken from different populations.
Q.19 What do you understand by Gauge R & R?
Gage R&R, stands for gage repeatability and reproducibility. It is a statistical tool which measures the amount of variation in the measurement system arising from the measurement device and the people taking the measurement.
Q.20 What do you understand by Defects Per Unit or DPU?
DPU measures the average number of defects per every product unit and is calculated by dividing the total number of defects found by the number of units. For example, if 30 units are produced and a total of 60 defects have been found, the DPU equals 2.
Q.21 What do you understand by DPMO?
DPMO or Defects Per Million Opportunities is a ratio of the number of defects in one million opportunities. It is calculated as- DPMO = DPO x 1,000,000. It refers to, how many times did you have a flaw or mistake (defect) for every opportunity there was to have a flaw or mistake.
Q.22 What is the difference between the R SQR and R SQR adjusted?
Both are used in regression analysis. Adjusted R-squared is a modified version of R-squared that has been adjusted for the number of predictors in the model. The adjusted R-squared increases when the new term improves the model more than would be expected by chance. It decreases when a predictor improves the model by less than expected.
Q.23 What is the difference between specification limits and control limits?
Control limit is process driven and is calculated from process data for a particular control chart. An X-bar chart and an Individual measurements chart will have different limits. Specification limits are chosen in numerous ways or is given by the client and usually apply to the individual items being measured and appear on histograms, box plots, or probability plots.
Q.24 What are the key factors of ANNOVA?
The key factors of ANNOVA are relationship difference of averages between two different populations, identification of dominating factors and estimation of different factors in variation of characteristics under study.
Q.25 What does the U-control chart helps in understanding?
The U-control chart illustrates the number of defects on different sample sizes.
Q.26 Which document provides the project outline and objective in a single glance?
Project charter provides the project outline and objective in a single glance.
Q.27 What do you understand by DFSS?
DFSS or Design For Six Sigma is an engineering design process and is used when designing a completely new product or service. DFSS is used when the current product or process cannot be improved to meet customer requirements, and is to be replaced.
Q.28 What is value in Lean?
The Value in lean is everything the customer is willing to pay for and also refers to the level of fulfilling a customer’s requirement by the product or service.
Q.29 What is affinity diagram?
An Affinity Diagram in six sigma is a tool which gather ideas, opinions and issues which are organized into homogeneous groupings or subgroups based on their natural relationships for developing solutions. The Affinity process is often used to group ideas generated by Brainstorming.
Q.30 What is spaghetti diagram?
A spaghetti diagram visually representation using a continuous flow line tracing the path of an item or activity through a process. It enables process teams to identify redundancies in the work flow and opportunities to expedite process flow.
Q.31 What is Pull in Lean?
Pull refers to the movement in production as per requirements or pull by the customer. A pull system is a lean manufacturing strategy used to reduce waste in the production process as, components used in the manufacturing process are only replaced once they have been consumed so companies only make enough products to meet customer demand.
