Replication as a mental model teaches us that we don’t always need to reinvent the wheel. Often a good starting point is what others are doing. Once you get a sense and a feel for the environment you can adapt to better suit your own needs.

What we need to remember is that effective replication requires enough structure and space to produce a copy, but enough flexibility to adapt that copy to changes in the environment. Just because something has worked for a while doesn’t mean that it will continue to be effective in perpetuity. Maintaining a successful approach requires an ability to grow and modify that approach as required.
