COMP3470 IS33 People-Centred Information Systems
Development
School of Computing FACULTY OF Engineering
  • Week 1 Lecture 2
  • IS Failure Case Studies

2
Is this you?
  • A Software Engineers approach to correcting
    systems failure ? http//www.sei.cmu.edu/cbs/monog
    raphs/case.study.correcting.pdf

Good! But can you do more?

Categories of IS failure
  • Process Failure no workable solution produced
    /or cost of the delivered IS over run
  • Correspondence Failure design objectives not met
  • Interaction Failure poor levels of user
    satisfaction or acceptance
  • Expectation Failure the inability of an IS to
    meet a specific stakeholder groups expectations

Literature, Oxford Surveys in IT, Vol 4,
pp.257-309

Different degree of failures
  • Total Failure system not operational
  • Partial Failure Type 1 Goal Failure (main
    stated goals not attained)
  • Partial Failure Type 2 Sustainability Failure
    (succeeds initially but then fails after a year
    or so)
  • Partial Failure Type 3 Zero-Sum Failure
    (succeeds for one stakeholder group but fails for
    another)

A classic case LASCAD project
  • LASCAD London Ambulance Services Computer
    Aided Despatch
  • How to conduct a case study?
  • get the facts on what happened (primary
    secondary sources? others?)
  • investigate context, cause effect
  • analyse using some kind of framework
  • lessons learned (recommendations)

6
Sources of information
  • Beynon-Davies P (1995), Information systems
    failure the case of the London Ambulance
    Services Computer Aided Despatch project,
    European Journal of Information Systems, Vol. 4
    pp.171-184
  • Report of the Inquiry into the London Ambulance
    Service (Feb 1993), access via http//www.cs.ucl.a
    c.uk/staff/A.Finkelstein/las.html

7
The old way
  • Read pp.176/177 of Beynon-Davies paper on the
    manual ambulance despatch system
  • Error-prone and inefficient .need
    computerisation!

8
LASCAD project what happened
  • Key dates
  • Late 1990 Feb 1991 writing system requirement
    spec
  • 7 Feb 1991 invitation to tender
  • June July 1991 systems design spec
  • Aug Sept 1991 contracts (2 suppliers) signed
  • Jan 1992 original planned implementation
  • 26 Oct 1992 full implementation (problems
    started - a flood of 999 calls swamping
    operators screens some went missing lots of
    automatic alerts generated etc.)
  • 4 Nov 1992 system crashed!

From the Inquiry Report

How LASCAD should work
  • Read Beynon-Davies paper p.177
  • (p.178 has a cause--effect diagram too)

So what went wrong? p.179
10
Context
  • NHS was under reform and there was already a
    climate of mistrust and obstructiveness
  • LAS management was under pressure to improve
    performance and to meet standards set
  • Staff was alienated to the changes rather than
    brought on board
  • 2 earlier unsuccessful attempts with CAD (early
    80s and 1989/90)

11
People issues as the framework for analysis
  • Individual inadequate training system assume
    perfect condition at coal face
  • Group change of layout in control room (the
    usual peer-support lost) no fall back position
    managements hope to use the system to bring
    about the desired change of working practice
    automatically
  • Organisation both systems and users were not
    ready for full implementation poor fit between
    system and organisational structure and
    operational procedure over-ambitious scoping and
    timetable the process of awarding CAD contract
    dubious poor project management

12
Recommendations by the Inquiry Team
  • Continue to implement a CAD
  • Better IT procurement guidelines (more than
    financial aspects)
  • CAD should be follow these imperatives
  • Reliable/resilient
  • Total ownership by management and staff
  • Timescale which allows consultation, QA, testing
    and training
  • Staged delivery with maximum benefits first
  • Re-training of control room staff
  • Establish a project subcommittee of the LAS Board
    and recruit an IT Director who will have direct
    access to LAS Board

13
For next week!
  • Write down on a piece of paper a list of people
    issues raised in this article
  • Dennis A R, Carte T A and Kelly G G, Breaking

    groupware-supported business process
