material that has been received. These files will be kept by each fiscal year. The filing system will be kept in requisition number order. You should review  this  file  at  least  weekly  to  make  sure  of completeness  and  orderliness. Stock  Record/Requisition  Files The stock record/requisition files are the most important  that  a  supply  department  has  to maintain.  These  files  are  the  records  of  all  the material  that  you  carry  on  board  and  the requisitions   that   you   have   submitted   and completed. You must update your stock record file daily by  posting  issues,  receipts,  shortages,  and  any inventories that have occurred. These cards should be filed in stock number order by national item identification  number  (NIIN),  You  should  have two  separate  card  files,  one  for  high-usage  or selected item management (SIM) items and one for  low-usage  or  non-SIM  items. The requisition file must be kept by fiscal year. This file will be kept in requisition number order. You  should  maintain  this  file  according  to  the Navy and Marine Corps Records and Disposition Manual,  SECNAVINST    5212.5. DISPOSAL OF RECORDS Files and records are disposed of according to the  Navy  and  Marine  Corps  Records  and Disposition   Manual.   A  ship  or  shore  station should  have  instructions  written  regarding  the disposal  of  classified  files. Aboard  ship,  usually  you  can  dispose  of classified files by either burning or shredding the material. You should always keep a log of which files  you  shred  or  burn. CLOSING OUT FILES Closing  out  files  is  accomplished  on  a  specified date. You transfer the closed-out files to a local storage  location  and  then  open  new  files.  This should be done at the end of each fiscal year for fiscal  and  accounting  records.  Correspondence and general files should be closed out at the end of  the  calendar  year. SECURITY OF FILES The supply officer and you should make sure all  office  records  are  safeguarded  from  loss  or accidental  destruction.  Such  records  will  be removed   from   the   supply   office   only   when absolutely  necessary.  Any  files  that  are  in  the possession  of  your  personnel  should  be  handled according  to  the  Department   of   the   Navy Information  and  Personnel  Security  Program Regulation,   OPNAVINST   5510.1,   and   any pertinent  shipboard  instructions. PERSONNEL   MANAGEMENT One  of  the  concerns  of  personnel  management is  the  assignment  of  personnel  on  the  basis  of capacity   and   interest   to   perform   specific functions,   tasks,   and   duties.   It   involves recognizing  that  every  individual  uses  a  basic knowledge, skill, or ability in performing a task and  these  capacities  should  be  fully  used.  You should   be   able   to   exercise   your   leadership responsibilities   in   dealing   with   these   human relations.  Leadership  can  be  defined  as  the  ability to   direct   or   influence   the   behavior   of   others toward specific goals. In carrying out this mission, your  responsibilities  do  not  stop  with  the assignment   of   duties   and   the   delegation   of authority.  You  must  also  control  the  functions. Refer to  Human   Behavior   and   Leadership, NAVEDTRA  10058.  This  manual  is  written  for leading  petty  officers  of  the  U.S.  Navy  to  assist them in leading their people. As a first class, you will be required to attend a highly interactive Navy leader   development   program   (NLDP)   course before going up for chief. This training will help you  in  making  personnel  assignments  and  will improve  your  general  leadership  ability. PERSONNEL  ASSIGNMENT One  of  the  most  difficult  tasks  facing  a supervisor   is   making   a   fair   and   efficient distribution  of  individual  jobs  among  assigned personnel.  If  this  could  be  done  by  a  simple mathematical  formula  (jobs  ÷  available  per- sonnel   =   distribution),   it   would   present   no problem.  However,  it  is  not  that  simple.  Your personnel  will  have  varying  degrees  of  knowledge and   experience. Also,  the  jobs  differ  in complexity,  required  time  to  perform,  and frequency  of  performance.  While  the  ultimate responsibility for the assignment of personnel rests with   the   supply   officer,   this   officer   will   rely heavily  on  your  recommendations. What Are the Jobs? The  first  step  in  planning  personnel  as- signments is to prepare a list of all jobs that are 1-10
