and  positions  in  excess  of  those  requirements.  To guarantee optimum manpower use, each commanding officer must annually review and evaluate his or her MPA,  including  mobilization  requirements  and,  when appropriate,  recommend  changes  to  his  or  her manpower   claimant   via   the   chain   of   command. Particular emphasis should be placed on identifying areas in which manpower may be saved or skill levels reduced  without  adverse  effect  on  accomplishment  of the mission of the command. The  following  actions  should  be  taken  when submitting  change  requests: .  Before  requesting  an  increase  in  manpower resources  because  of  changes  in  tasks  or  increased workload,  analyze  all  manpower  requirements  (military and  civilian)  and  the  billets  and  positions  authorized. Accommodate  increased  requirements  by  reassigning existing  resources  to  the  extent  feasible. l  Minimize  the  number  of  manpower  authorization change requests by proper planning, annual billet and position reviews, and consolidation of desired manpower changes. .  Make  sure  change  requests  are  submitted sufficiently in advance of the requested effective date of change to permit adequate time for review at the various levels   of   the   chain   of   command,   for   thorough consideration by CNO, and for orderly response by personnel distribution authorities. It should be under- stood that, due to fiscal constraints, rotational patterns, training  support,  and  deployment  schedules  in  the  case of  ships  and  squadrons,  actual  manning  of  newly authorized billets may not be satisfied in less than 9 to 12 months from the date of approval. l Make sure each requested action is complete and accurate  and  includes  necessary  mobilization requirements. . If it becomes necessary to request increases in manpower resources and no compensation is available from within the manpower assets of the activity, indicate a priority for each of the requested billets or positions to assist  the  manpower  claimant  in  making  recommenda- tions  to  CNO.  Should  any  subsequently  identified compensation be insufficient, invalid, or unacceptable, approval of only portions of the request may be possible according to the stated priorities. . Summarize requested changes by designator/ grade, rate/rating. . Make sure complete justification is provided for each  request  for  revision. .  In  certain  instances,  when  specific  functions  or an activity prevent geographic collocation or require a separate program element code or sea/shore code from that of the parent activity, requests for establishment of components  to  the  parent  activity  MPA  should  be submitted. Justification for the establishment of the component  must  be  submitted  under  OPNAVINST 1000.16G,  article  506. SUPERIORS IN CHAIN OF COMMAND When  requests  for  changes  are  forwarded  that include  quantity  or  grade  increases,  but  do  not  identify compensation,  the  chain  of  command  must  make recommendations  regarding  compensation.  In  the  event compensation  is  to  be  provided  by  reprogramming manpower from another activity, such recommenda- tions  must  identify  by  activity  and  sequence  code  the billets  to  be  reprogrammed.  While  compensatory recommendations   are   not   currently   required   for revisions  to  mobilization  requirements,  these  require- ments  should  be  carefully  reviewed  to  avoid  unjustified increases.  Include  a  corrected  OPNAV  Form  1000/4A  if appropriate. Forwarding  endorsements  should  indicate  whether changes  are  considered  to  be  applicable  to  other activities having the same mission, tasks, functions, or equipment. This is particularly applicable to recom- mendations  for  ship  or  aircraft  squadron  classes originating within the chain of command of a fleet commander  or  type  commander  (TYCOM).  Where changes  appear  to  be  applicable  to  given  types  or classes, both fleet commanders and TYCOMs should be provided copies of the request for their comments and recommendations. ADVISORS To assist CNO and BUPERS in executing their responsibilities  with  regard  to  officer  manpower  and personnel,  officer  designator  advisors  are  designated from among the Deputy and Assistant Chiefs of Naval Operations  and  commanders  of  systems  commands.  An advisor  is  assigned  for  each  billet  and  personnel designator specialty category. In addition, the Deputy and Assistant Chief of Naval Operations, commanders of  systems  commands,  and  other  offices  are  assigned officer  subspecialty  system  consultants,  coordinators, and  sponsors  responsibilities.  The  assigned  officer designator  advisors  and  subspecialty  sponsors  and 8-4
