Documenting a process leads to a specific result. If the process is well written, it will lead to a consistently positive result. Moreover, the rest of the team can follow it and reproduce your desired results. Note that all businesses already have a process, even if it’s not in writing. You teach a new team member how to reset a password using a series of actions that lead to a particular result. They can follow the process without documentation. Undocumented processes may be efficient with a small team. However, you risk Leaky Bucket Syndrome (LBS) every time you grow. LBS is the tendency to lose some knowledge as each person passes on their learning to another.
