Two  other  SERT  responsibilities  are  (1)  follow- up  action  of  verification  or  retesting,  and  (2)  com- plete  shipboard  and  maintenance  data  collection subsystems   reporting.   Effective   corrective   mainte- nance management first requires the consideration of combat systems readiness, then efficient use of man- power.  These  factors  closely  relate  to  the  ship’s employment and the tactical environment. There  will  be  times  when  more  corrective  main- tenance   requirements   exist   than   can   be   simulta- neously  handled  by  the  available  manpower.  In addition, sometimes parallel faults exist that require the same personnel or the same system setup for fault isolation. When these conditions occur, the setting of repair  priorities  is  based  on  management’s  require- ments for readiness and available manpower to make the  repairs. As the SERT collects and evaluates PMS results, it  should  continually  base  its  recommendations  for correcting faults on the tactical situation, complexity of   fault   isolation,   and   available   manpower.   Some faults  may  be  designated  for  correction;  others  may be  deferred.  However,  deferred  faults,  if  left  to  ac- cumulate, tend to degrade overall systems readiness. Therefore, as soon as the situation permits, deferred faults should be repaired. Faults  detected  within  combat  systems  must  be isolated to a subunit that can be replaced or repaired or  to  an  alignment  that  can  be  made  before  actual corrective action can be taken. Therefore, technicians must have a thorough knowledge of the systems and access to complete systems and equipment documen- tation. Most   subsystems   and   equipment   maintenance publications provide fault-isolation support in one or two  formats.  The  first  format  consists  of  symptoms presented  in  preselected,  logical  steps  and  in  refer- ence  tables,  a  logic  chart,  or  logic  diagram  format. The  second  format  consists  of  flow  diagrams  and relay  ladders.  The  CSTOM  provides  amplifying  in- formation on fault isolation. After a repair priority has been set and the faults isolated,   the   managers   of   corrective   maintenance must ensure that corrective action is taken, verifica- tion is made by retest, and required reports are com- pleted.  Since  some  faults  tend  to  be  repetitive,  the SERT should keep records of fault symptoms, identi- fication,  and  corrective  measures. SERT  Monitoring The  SERT  responsibility  for  operational  training is vital since overall readiness assurance is a function of  operational  readiness  (personnel  proficiency)  and materiel readiness. The goal of operational readiness is  to  achieve  maximum  combat  systems  capability for  each  mission  under  constantly  changing  condi- tions of materiel readiness. The measurement of per- sonnel   readiness   is   based   on   the   three   following techniques: 1.    PMS  tests:  In  each  case,  the  hardware  must be  operating  properly.  Otherwise,  the  capabilities  of the personnel cannot be determined accurately. 2.    Simulators  or  computer  programs:  The  video signal  simulators  with  computer  programs  provide  a means  to  assess  the  skill  of  the  console  operator. However,  the  computer  programs  are  limited  in  as- sessing the capabilities of combat systems operators. 3.  Monitoring  of  ship  or  fleet  exercises:  one way to evaluate the capability of all combat systems personnel  is  to  actually  monitor  ship  or  fleet  exer- cises.  These  exercises  include: Electronic  warfare  exercises. Gunnery  exercises  (antiair  [AA],  surface, and shore). Missile  exercises  (AA  and  surface.) CIC  exercises  (aircraft,  tracking  and  con- trol). Antiship  cruise  missile  exercises. ASW  exercises. When  the  SERT  finds  personnel  deficiencies,  it must  provide  operational  training  and  guidance. 4-15
