Brill Mindz Technologies Interview Questions and Answers

SPC tools commonly used in Six Sigma include control charts, histograms, Pareto charts, scatter plots, and fishbone diagrams.

• Control charts are used to monitor process stability over time.

• Histograms display the distribution of data.

• Pareto charts help identify the most significant factors affecting a process.

• Scatter plots show the relationship between two variables.

• Fishbone diagrams (Ishikawa or cause-and-effect diagrams) are used to identify root causes of problems.

FMEA stands for Failure Mode and Effects Analysis. It is used to identify and prioritize potential failures in a process or product.

• FMEA is a systematic method for analyzing potential failure modes of a process or product.

• It helps in identifying the potential effects of these failures on the system.

• FMEA prioritizes the failures based on their severity, occurrence, and detection.

• It is used to proactively address and mitigate risks in a process or product.

• Example: FMEA can be u...read more

Non parametric tests are statistical tests that do not make assumptions about the parameters of the population distribution.

• Non parametric tests are used when the data does not meet the assumptions of parametric tests.

• They are distribution-free tests, meaning they do not require the data to be normally distributed.

• Examples of non parametric tests include Mann-Whitney U test, Wilcoxon signed-rank test, and Kruskal-Wallis test.

Agile is a project management methodology that emphasizes flexibility, collaboration, and continuous improvement.

• It promotes adaptive planning, evolutionary development, early delivery, and continuous improvement.

• Agile helps teams respond to changes quickly and effectively, leading to better outcomes and higher customer satisfaction.

• Examples of agile methodologies include Scrum,...read more

Control charts are used to monitor process variation and detect out-of-control conditions, while run charts simply display data over time.

• Control charts have control limits to determine if a process is in control or out of control.

• Run charts do not have control limits and are used to display trends over time.

• Control charts are typically used in statistical process control to monitor process stability and identify special causes of variation.

• Run charts are more commonly used t...read more
