What analytical strategy is typically selected if a problem is waste or cycle time related?

Correct Answer
Lean
Lean analysis

Explanation
Lean is typically selected as the analytical strategy for problems that are waste or cycle time related. Lean focuses on eliminating waste and improving efficiency in processes, making it the ideal approach for addressing these types of issues. Lean analysis is a specific method within Lean that involves identifying and analyzing waste and inefficiencies in order to develop solutions and improvements. Therefore, both Lean and Lean analysis are appropriate strategies for addressing waste or cycle time related problems.

What is the FMEA ?(more answers possible)
- A.
  
  A method focusing on preventing or mitigating problems
- B.
  
  An analysis to understand failure modes & effects
- C.
  
  A tool enabling to track the actions taken to address problems
- D.
  
  A tool to measure the future effects of change
Correct Answer(s)
A. A method focusing on preventing or mitigating problems
B. An analysis to understand failure modes & effects
C. A tool enabling to track the actions taken to address problems

Explanation
FMEA stands for Failure Mode and Effects Analysis. It is a method that focuses on preventing or mitigating problems by analyzing failure modes and their effects. It is also a tool that enables tracking the actions taken to address problems. FMEA helps in identifying potential failures in a process or system and prioritizing them based on their severity, occurrence, and detectability. By understanding failure modes and their effects, organizations can take proactive measures to prevent or minimize the impact of failures. Additionally, FMEA provides a systematic approach to measure the future effects of change, ensuring that any modifications or improvements are thoroughly evaluated for potential risks.

What enables to look at data in multiple layers of information (what, when, where, who,...) ?
- A.
  
  Root cause hypotheses
- B.
  
  Sampling
- C.
  
  Stratification
- D.
  
  Survey
Correct Answer
C. Stratification

Explanation
A root cause hypothesis is a potential explanation for the problem; Sampling allows to use a smaller group to represent the whole; a Survey helps to collect customers' answers to a series of questions.

What is the name of the chart representing upper and lower control limits (the amount of expected variation in the data) ?

Correct Answer
control
control chart
run chart
statistical process control
SPC

Explanation
The correct answer is "control chart". A control chart is a graphical representation of data that shows the upper and lower control limits, which indicate the expected variation in the data. It is used in statistical process control (SPC) to monitor and analyze processes over time. A run chart is a different type of chart that displays data points in chronological order, while "control" and "SPC" are just partial terms that do not fully describe the chart.
