Processes, procedures and policies are the guidelines that a company follows to make sure they are operating in a way that is both effective and safe. Every business needs them, however, sometimes it can be confusing as to where one starts and another ends. Often businesses muddle up their use or refer to the wrong one when really meaning another.

At a high-level Processes, Procedures and Policies can be defined as:

1. Policies – the guidelines that dictate how processes and procedures should be carried out.

2. Processes – the steps of tasks that need to be completed in order to complete a project.

3. Procedures – the set of instructions for completing a process.
