Pareto analysis helps identify the most significant causes of defects by focusing on the vital few versus the trivial many.
Fishbone diagram (Ishikawa diagram) helps visualize all possible causes of a problem to identify root causes.
5 Whys technique involves asking 'why' multiple times to get to the root cause of a defect.
Scatter diagram helps identify p...read more
Q6. Difference between foreach and map
foreach is used to iterate over an array and perform a function on each element, while map creates a new array by applying a function to each element.
foreach does not return a new array, while map does
