=== Standards development process ===

The P25 User Needs Working Group (UNWG), which represents P25 users, identifies user needs for the P25 standards, which are communicated to the P25 Steering Committee. The P25 Steering Committee adds identified P25 user needs to the Statement of P25 User Needs (SPUN) document. The [[Telecommunications Industry Association|TIA]] TR-8 Engineering Committee and its subcommittees, which represents manufacturers in the P25 industry, is then expected to develop TIA-102 standards that satisfy identified P25 user needs.<ref>{{Cite web |date=December 2021 |title=Project 25 (P25) Steering Committee Representative Handbook |url=https://www.cisa.gov/sites/default/files/publications/22_0105_p25-steering-committee-member-handbook_public_508C.pdf |url-status=live |archive-url=https://web.archive.org/web/20250422131451/https://www.cisa.gov/sites/default/files/publications/22_0105_p25-steering-committee-member-handbook_public_508C.pdf |archive-date=22 April 2025 |archive-format=PDF |access-date=10 May 2025 |website=[[Cybersecurity and Infrastructure Security Agency]] |format=PDF |ref=P25SCRHandbook}}</ref>

Once developed, TIA-102 standards may also subsequently be adopted by the P25 Steering Committee as P25 standards, and adopted by [[ANSI]] as American National Standards; however, TIA-102 standards do not automatically become P25 standards, and some TIA-102 standards have never been adopted by ANSI.<ref>{{Cite web |date=13 September 2024 |title=Approved Project 25 Standards |url=https://www.project25.org/images/stories/ptig/P25_Standards_Documents/P25%20SC%2024-09-002%20P25%20TIA%20Standards_Approved%20Sep2024.pdf |url-status=live |archive-url=https://web.archive.org/web/20250304022714/https://www.project25.org/images/stories/ptig/P25_Standards_Documents/P25%20SC%2024-09-002%20P25%20TIA%20Standards_Approved%20Sep2024.pdf |archive-date=4 March 2025 |archive-format=PDF |access-date=10 May 2025 |website=Project 25 Technology Interest Group |format=PDF |publication-date=26 September 2024 |ref=ApprovedP25Standards}}</ref> The TIA-102 standards, P25 standards, and associated ANSI standards have not been adopted by [[International Organization for Standardization|ISO]] as de jure international standards; however, P25 systems have been deployed in 83 countries, so they nonetheless serve as one set of [[De facto standard|de facto international standards]] alongside other international [[Land Mobile Radio]] (LMR) standards such as [[TETRA]] and [[Digital mobile radio|DMR]].<ref>{{Cite web |last=Giggetts |first=Cheryl |date=October 2023 |title=P25 for the Future: New Standards, Interoperability and Security for 2023 and Beyond |url=https://melbourne.comms-connect.com.au/wp-content/uploads/2023/11/P25-for-the-Future-20231010.pdf |url-status=live |archive-url=https://web.archive.org/web/20250510022931/https://melbourne.comms-connect.com.au/wp-content/uploads/2023/11/P25-for-the-Future-20231010.pdf |archive-date=10 May 2025 |access-date=10 May 2025 |website=Comms Connect |publisher=Principal CTA Consultants |format=PDF |ref=P25ForTheFuture}}</ref>
