Within NAVAIR, the path followed is the Navy's Systems Engineering Technical Review (SETR) process, a series of technical reviews performed throughout the acquisition lifecycle for assessing technical maturity, design maturity, and the ability to meet user requirements and expectations.
The PIA process leverages data from the SETR process technical reviews leading up to Milestone B of the acquisition framework.
Program offices determine how to implement industrial maintenance planning by using the tools provided in the SPI for IDM (including the PIA process) aligned to the SETR process.
