SOPs should live wherever your team actually looks. That might be a shared drive, knowledge base, intranet, or internal portal. The most important factor is accessibility. If people cannot quickly find the procedure they need, the documentation will not get used.
In many organizations, SOPs work best when they live in a dedicated documentation area rather than scattered across folders. A structured location makes it easier to maintain consistency and avoid multiple versions of the same procedure.
It is also helpful to use a numbering or coding system so procedures can be easily referenced, logged, and maintained. A simple structure allows teams to track revisions, locate procedures quickly, and keep documentation organized as the library grows.
The goal is not just to store SOPs, but to place them somewhere the team will naturally go when they need guidance.
