Background The Commerce Spectrum Management Advisory Committee (CSMAC) advises the Assistant Secretary for Communications andInformation at NTIA on a broad range of spectrum policy issues. Committee members offer expertise and perspective on reforms toenable new technologies and services, including reforms that expedite the American public's access to broadband services, publicsafety, and long-range spectrum planning. The CSMAC created five working groups to consider ways to facilitate the transition of the 1695–1710 MHz and 1755–1850 MHzbands for commercial wireless uses. Working groups consisted of federal agency stakeholders, industry members, and NTIA andFCC staff liaisons. From May 2012 to August 2013, the working groups organized, developed work plans, convened face-to-face and teleconferencemeetings, drafted and edited reports, provided updates to the full CSMAC through the member liaisons, and delivered final reports andrecommendations for consideration by the Committee. NTIA convened a meeting on December 13, 2013 to discuss ‘‘lessons learned’’ from the CSMAC working group process in order toidentify recommended best practices for future improvement and to incorporate them appropriately into NTIA processes.1 Recommended Best Practices Lessons-learned participants were generally positive regarding the working group process as a whole. Much of the discussion focusedon information sharing. As a result of the meeting, participants suggested a number of lesson-learned ideas and recommended bestpractices, which are summarized and categorized into major themes below. NTIA will address these lessons learned/best practicessuggested by the CSMAC working group participants and indicate actions that will be taken based on them. 6.Trusted Agent and Information Sharing •Informationsharing would be having industry members with the appropriate clearances. If somegovernment entity possesses sensitive or classified information and there is an established need to know bythat commercial entity, then it would seem relevant that the federal agency sponsor industry members.(page 80, line 22)•The concept of the trusted agent needs to be figured out up front in the next process as this issue had taken along time. (page 81, line 17)•Perhaps NTIA or DOD or DOJ can sponsor the clearances. (page 81, line 14)•There needs to be a common understanding on DOD information sharing and what information should beshared. The DOD understands that industry needs a certain amount of information to make a solid businessdecision, but the DOD has to protect the data and information. The DOD is looking at this from a granderscale when it comes to sharing, to figure out what that grander scale of sharing information is going to looklike or result in. (page 83, line 14)•The current NDA process that is in place is not a sustaining process, where there are only a limited numberof industry folks sharing information.(page 86, line 9)•Perhaps looking at the FACA and the process may help in order to have closed and classified meetings asother agencies with FACAs do. (page 93, line 5)•Export control and ITAR should also be looked at in this process (having people dial in from outside theUS, non-US citizens in the room is a concern) (page 93, line 17)•Consider having NTIA and FCC as trusted agents for the federal and non-federal entities or an individualcontractor. There are different ways to approach this, but the conversation on how best to do it needs tocontinue. Perhaps the trusted agent can serve as the main focal point for analysis methodologies andparameters. This trusted agent can then establish trust between all parties, and then the DOD or thegovernment can run the analyses while safeguarding the data so that both sides are comfortable that there ismutual trust. This approach may facilitate sharing more easily. (page 103, line 3) 7.Production, Process, and Output •Interim reports for the CSMAC along the way would inform members of progress sooner rather than later.(page 35, line 12)•With the formal report writing, it would have been helpful in identifying up front in terms of who is incharge and providing a framework for all of the working groups if there are multiple working groups.Clearly identifying report writers would make it clear as to what people are signing up for right up front, asopposed to finding out later in the process. (page 115, line 18)•There were things that were discussed in some working groups that would have been of benefit to look atfurther, but were never done. Perhaps some sort of follow-on effort could be established. (page116, line114)
