How To Do Stuff vs. A Repeatable System
There are a lot of websites dedicated to more fluid methodologies, or specific methodologies that are done a certain way, such as that through How-To sites such as
https://www.wikihow.com/Main-Page
Which is a personal favorite site when it comes to learning how to do anything, and is often the most used method of learning something quickly and efficiently, in a summarized form, sometimes together supplemented with a Youtube video if it has slightly more complexity to it or there is a need for a visual aid to help describe what one is reading. The format, summaries, bullet points and pictures make it tremendously easy to both design a methodology, as well as for the reader to grasp how the system in mind is supposed to be executed somewhat.
There are other methodologies, which are repeatable systems, such as the scientific method itself and tend to apply universally and carry with them a much more extensive coverage of how they can be used. Sometimes these repeatable systems are so specific they must be done the same way each time, and each time they are expected to yield the same results, similar to how the scientific method dictates that a scientific experiment will only be valid if it can pass it’s test using it’s rules.
