Plain Language Questions (PLQ)

The publication of ISO 19650 set of standards replaces use of PLQ and instead introduce the term with exchange information requirements (EIR) and project information requirements (PIR).

Project information requirements (PIR)

PLQ and PIR are both expressions of the high-level information needed by the client and/or their stakeholders to make key decisions concerning the project. The PIR, like the PLQ, are used to develop the detailed and contractual EIR. However, PIR can also include non-technical requirements and therefore can be broader than PLQ.
