The
 LASCAD
 system
 was
 launched
 on
 October
 26,
 1992
 and
 it
 failed
 miserably
 on
 the
 very
 first
 day
 for
 various
 reasons,
 causing
 major
  delays
 in
 ambulance
 dispatch.
 The
 process
 was
 non
 optimal,
 some
 times
 many
 ambulance
 units
 where
 sent
 to
 the
 same
 scene.
 
  Series
 of
 errors
 in
 the
 implementation
 led
 to
 this
 under
 performance
 of
 the
 system.
 Major
 set
 backs
 in
 the
 design
 phase
 of
 the
 system
  was
  its
  complex
  algorithm,
  sophisticated
  concept,
  poorly
  designed
  and
  non
  friendly
  user
  interface.
  The
  system
  was
  developed
  in
  Visual
  Basic,
 which
 was
 an
 unproven
 tool
 then.
 
  Tight
 development
 schedule,
 inappropriate
 assumptions
 in
 the
 requirement
 specifications
 was
 some
 of
 the
 issues
 in
 the
 Management
  part
  of
  it.
  The
  management
  did
  not
  consider
  experts’
  concern.
  The
  project
  was
  contracted
  to
  the
  lowest
  bidder
  without
  enquiring
  about
  their
  previous
  experience
  in
  developing
  such
  dispatch
  systems.
 
  Major
  decisions
  where
  taken
  by
  Non
  –
  IT
  members
  who
  had
  no
  technical
 understanding
 of
 the
 process
 flow
 and
 the
 concepts
 that
 constitutes
 the
 system.
 Staffs
 were
 not
 trained
 enough
 before
 they
  had
 to
 start
 using
 the
 system,
 which
 resulted
 in
 loss
 of
 control
 and
 incorrect
 information
 being
 fed
 into
 the
 system.
  When
 the
 system
 came
 online
 it
 faced
 problems
 like
 calls
 getting
 wiped
 off,
 incorrect
 allocation
 of
 ambulance.
 
 This
 kind
 of
 delays
 in
  dispatch
  once
  faced
  an
  incident,
  where
  the
  ambulance
  arrived
  very
  late
  to
  the
  scene
  to
  find
  the
  patient
  already
  been
  taken
  away
  by
  the
  undertakers.
  One
  another
  incident
  was
  when
  a
  stroke
  call
  was
  answered
  after
  11
  hours,
  which
  was
  suppose
  to
  happen
  within
  15
  minutes
 from
 the
 call.
  The
 operators
 then
 concluded
 the
 system
 to
 be
 unusable
 eights
 days
 after
 its
 launch
 and
 started
 using
 tape
 recording
 of
 calls
 reverted
 to
  the
 totally
 manual
 system.
 
  The
  inquiry
  team
  after
  investigating
  stated,
  “within
  the
  time
  constraints
  imposed
  on
  the
  project
  and
  the
  scope
  of
  requirements,
  no
  software
 house
 could
 have
 delivered
 a
