Mangan advises putting your knowledge in order. Collect like pieces of information and sort knowledge by field or interest. Create a card catalog of your knowledge. This facilitates rapid recall of what you know. Such organizing can lead to finding meaningful relationships or patterns. For reliability this would include sorting field failures, understanding user environments, etc. We deal with mounds of information; by putting that information in order we often create knowledge.
When considering a range of different failures for a product, a common technique is to arrange the count of each type of failure in descending order by count on a bar chart or a Pareto chart. The order indicates the most common failures to the least common.
Mapping faulty parts on a circuit board is another example of a way of organizing data that can be useful for revealing mechanical or thermal-related failure causes. Such visualizations can reveal previously undetected issue.

What do you mean with those words or concepts? Be clear with your understanding especially with yourself, to be clear with others. Learn to define the problem which may lead to specific solutions.
