2.  Destroy  any  superseded  edition  according  to your  local  disposal  procedures. As supervisor you should ensure that the personnel who  manage  the  technical  library,  or  function  as technical manual coordinators for the work centers, should be knowledgeable, responsible, and willing to help others. It is a job for personnel who understand the value of tools, the need to safeguard them, and the need to place them in the hands of the users who need them.  Such  management  will  play  a  vital  role  in maintaining the operational readiness or your com- mand. In  this  chapter  we  were  unable  to  give  all  the information you will need on the job. But we have tried to provide basic information and references to help you maintain a good reference technical library. PERSONNEL  MANNING Personnel manning will be a prime concern of the EMO;  however,  you  will  more  than  likely  be  quite involved  with  personnel  manning  within  your division.  A  division  must  have  the  correct  manning levels  to  function  properly,  filling  the  needs  of equipment   maintenance   and   other   shipboard functions,  such  as  general  quarters  watch  stations. Manpower requirements are normally accounted for by   the   Navy   manpower   requirements   system (NMRS). This section of the chapter will give you a back- ground in Navy manning and which to work. THE SHIP MANPOWER DOCUMENT  (SMD) the personnel “tools” with (MANNING) To effectively manage manpower and personnel, the  Navy  needs  an  accurate  identification  of  ship manpower  requirements.  The  main  function  of  the ship  manpower  document  (SMD)  and  preliminary ship  manpower  document  (PSMD)  programs  is  to document  manpower  requirements.  This  is  done  in terms   of   quantity   and   quality   (such   as   skills, experience  levels,  and  specialized  training), required  to  perform  mission  requirements  specified in  the  required  operational  capabilities  (ROC)  and projected   operational   environment   (POE)   state- ments. An ROC statement lists all required operational capabilities (ROCs) for a class of ships, a type of aircraft squadron, or other unit as assigned by the CNO. Example: ROC 1. 2. SUBROC   1. 2. Engage submarines with antisub- marine  armament. Engage  airborne  threats  using surface-to-air armament. Attack  with  torpedoes. Engage  airborne  threats  using installed  AA  weapons. A POE statement is a listing of the most demanding conditions (wartime and peacetime) of operation for which a unit must be manned. Example: At sea in wartime, capable of performing all offensive and defensive functions simultaneously while  in  Readiness  Condition  1;  capable  of  performing other functions that are not required to be accomplished simultaneously. The   SMD   is   developed   in   six   phases:   data collection,   workload   standards   development   or validation, generation of a preliminary statement of required billets, fleet review, publication of final billets, and  implementation.  The  Navy  manpower  requirements system provides automated data processing support for each of these phases. If  a  ship  is  modernized  during  its  service  life (equipment or systems updated or added), the SMD provides   a   means   for   determining   manpower requirements for the modified systems or mission. The NMRS can generate an SMD to identify billets needed  to  operate  and  maintain  new  weapons, equipments,  and  systems,  far  enough  in  advance  of  fleet introduction to provide trained personnel both when and where  they  are  needed. In  addition,  the  shipboard  managers–from  the commanding  officer  down  to  the  LPOs–can  use  the SMD  as  an  effective  source  document.  Since  it  has detailed  watch  station  requirements,  it  can  serve  as  the basis for the establishment of a battle organization and watch  bill  for  specific  conditions  of  readiness. DESCRIPTION OF THE SMD We have discussed the importance of the SMD as an element of the Navy manpower management process. It presents the basic manpower requirements summary in  seven  sections  as  follows: Section I Officer billet summary. Consol- idates officer   requirements   into   a   single section. 2-11
