QUESTION AND ANSWERS:
Which of the following is the key benefit of multi-vari charting?
Answer: It keeps track of the time when measurements were made
It graphically displays the variation in a process
It assists in the breakdown of components of variation
It is much easier to plot than most control charts
A multi-vari chart is a graphical representation of multiple variables on the same chart. Data variation can come from multiple sources.
………. statistics is used to apply to describe the data using numbers, charts, and graphs and the ……….statistics used determine the interrelationship of population parameters
Answer: Descriptive; inferential
Descriptive statistics deals with data presentation in numeric or graphic form or table form for data analysis. Inferential statistics: this is a technique of inferring about the population on the basis of observations obtained from the population.
A —– is used to explain the time scheduled by separate phases by breaking down the project processes and tasks for the dependencies to be accounted.
- Bar chart
- SPC chart
- PDCA
- Gantt chart
Gantt chart: Gantt chart is a type of bar chart which represent the start and finish dates of the project and shows many crucial elements like resources, milestones, tasks and dependencies.
Which of these are not Multivariate analyses?
- Factor analysis
- MANOVA
- ANOVA
- Cluster analysis
Anova stands for analysis of variance. Anova is a business process improvement methodology. Anova analysis is the analysis of variation in mean (not median or mode) of different groups of the population or different populations. When root cause analysis methods like DMAIC, or DFSS cannot depict the errors then Anova analysis is recommended.
What do you mean by gauge R&R?
Answer: When we are concerned about repeatability and reproducibility, then we use gauge R&R to describe the difference between repeatability and reproducibility. We shift our focus on the P -values and, if not the normal values, and try to make the box-Cox transformation as accurate as possible.
How would you define the Alpha and beta risk?
Answer: To understand the concept of Alpha and beta risk, we need to close leave understands the pea value in closer details. When the P-value is more than 0.05 or 5%, then it is defined as H 0. If the pee value is lesser than this, then it is called Ha. the concept of the value runs on probability, but when we proceed with 95% of confidence with the sample, then we are prone to risks of 5%.
Now, if the P-value is more than 5%, then the risk is on the higher side making consequences unacceptable if not dealt with immediately. The higher risk is defined as the Alpha risk well; the lowered risk is called beta risk.
How would you define an affinity diagram?
Answer: This is an analytical tool that is used to organize ideas into subgroups by having a common theme of relationship to develop solutions after brainstorming. To proceed with this, we need to have an affinity group who quietly puts their ideas of operative quality and initiates the brainstorming session. Then all the solutions given by the group are aligned and segregated into homogeneous groupings with affinity headings above it. And in this way, the candidate visualizes the solutions and list their numbers accordingly.
What are the different quality levels of six Sigma?
Answer: The methodology of Six Sigma is developed on measuring the quality of a process, and at every Six Sigma level, correspondence is achieved to several acceptable defects per million or to the extent that is optimum to six Sigma. The optimum six Sigma level, which is to be achieved, goes by 3.4 defects per million opportunities. This number gives us a general overview of the output levels.
One defect in every 69,0000 articles or outputs is permissible, whereas two defects in every 308 537 outputs are permissible with three defects in 66807 outputs are permissible. While the six Sigma considers four defects in every 6210 output are normal and five defects in every 233 outputs to be normal. This, if so, the window for six defects in every 3.4 outputs.
Define the spaghetti diagram?
Answer: A spaghetti diagram is used to limit or eliminate different forms of waste from the pipeline. This also includes reducing waste in transportation, motion, and waiting time. In this dire need of heavy competitiveness among each other, companies and multinationals are taking a step further by developing spaghetti diagram that is a part of lean tools to offer efficiencies in work layouts, transport-related waste, non-value items, the fatigue of people and adding value to the concept of lean.
When should we use Kaizen events?
Answer: In situations where we need to establish incremental improvement, Kaizen serves as the best solution by bringing quick solutions to two pressing problems that appear to be very significant. This is highly efficient in handling intensive cross-functional collaboration; with a quick solution, we can aggravate improvement in nearly three to five days of implementation.
Define control charts?
Answer: On six of March, when we need to evaluate the durability of a process over a given period of time, then we use control charts as a tool to graph and state whether the process is scaled between the permissible limits or not. It adds value to the time and resources of the company by saving additional efforts. Along with control charts, we use histograms to develop and evaluate observations that are helpful in determining the process needs.
What, how, and why control is required?
Answer: Before we understand the needs for control, we need to understand data projection, continuous use of data, discrete data, and their users in control charts. In Minitab and Nelson’s rule, control needs are devised once the improvement is sustained in the due process. This is usually carried out after the completion of the project so that we can find no prevailing issues. To strengthen control, we need to have information off continuous data and discrete data fed into the control chart. Here box plots and histograms are used for different purposes in differentiating between the control and run chart.
What do you mean by effect size?
Answer: When we measure the overall magnitude in quantitative terms, then we use or experiment effect size. This helps us to understand the size of the impact and the relationship it has between other variables.
What is project scope?
Answer: The project scope is used to make boundaries for the project so that team should keep their focus inside of the boundary and anything beyond boundary is not questionable for the projects. Such that boundaries can be limited to one process, location, people and time durations.
How will you define the problem statement?
Answer: The problem statement to be defined should be clear and crisp. Also problem statement should be defined in metrics such that it is easier to make the stakeholders understand in case the problem has not been resolved, also the future consequences also should be shared with stakeholders.
