Marketing & PR
Reaching out to customers, industry & journalists
Marketing and PR are where strategy becomes public, and the reasoning behind past choices is exactly what gets lost.
The useful institutional knowledge here is not the campaigns themselves but the logic behind them: why a particular audience was prioritized, what messaging was tested and dropped, what the press coverage actually said versus what was hoped for. That context rarely survives a team change.
For smaller organizations, marketing knowledge is often concentrated in one or two people who carry the brand voice, the agency relationships, and the history of what has been tried. When those people leave, the organization often ends up repeating experiments that have already been run.
Keeping a plain record of active initiatives, key contacts, the channels being used, and the messaging that currently works gives the next person enough to build on without starting from scratch.
