I would define organisational policies as a set of rules, regulations, procedures, and processes that govern how it is managed or governed. Organisational policies provide direction and better management for businesses as they are followed internally by employees.
In some cases, as I will highlight later, having organisational policies may be required by some stakeholders such as government and donors. Some clients especially in the global market require their suppliers to have in place policies such as anti-slavery, anti-terrorism and so on.
