The process flow diagram is then used to develop a [[piping and instrumentation diagram]] (P&ID) which graphically displays the actual process occurring. P&ID are meant to be more complex and specific than a PFD.<ref>{{Cite web|url=https://hardhatengineer.com/how-to-read-pid-pefs-drawings/|title=Learn How to Read P&ID Drawings - A Complete Guide|website=hardhatengineer.com|language=en-GB|access-date=2018-09-11}}</ref> They represent a less muddled approach to the design. The P&ID is then used as a basis of design for developing the "system operation guide" or "[[Functional specification|functional design specification]]" which outlines the operation of the process.<ref>{{Cite news|url=https://scottmanning.com/content/functional-design-specification/|title=Functional Design Specification|date=2 April 2006|work=Historian on the Warpath|access-date=2018-09-11|language=en-US}}</ref> It guides the process through operation of machinery, safety in design, programming and effective communication between engineers.<ref>{{Cite web|url=https://www.aiche.org/sites/default/files/docs/webinars/BarkelB-PIDs.pdf|title=Piping and Instrument Diagrams|last=Barkel|first=Barry M|website=AICHE|access-date=11 September 2019}}</ref> |
