The phrase documented procedure refers to the utilization of a written document as described under the definition above for document for the purpose of establishing a permanent written record of the processes and procedures that must be followed during the process of carrying out a particular activity, process, and/or methodology. These documentation procedures can be documented in any number of formats. They can be recorded on hard copy paper format for eventual long-term usage and perusal. They can also be documented electronically via a computer or other electronic recording device for easier distribution among large numbers of users, either within the specific current project team, or among individuals who may be conducting or participating in a similar type of project in the future and are seeking some examples of how the project was done in the past. The procedures can be documented as the project is ongoing or it can be documented in summation at the conclusion of a project.
This term is defined in the 3rd edition of the PMBOK but not in the 4th.
