Good! But can you do more?
3Categories 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,

4Different 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)

5A 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)
6Sources 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

7The old way
- Read pp.176/177 of Beynon-Davies paper on the
manual ambulance despatch system - Error-prone and inefficient .need
computerisation!
8LASCAD 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
9How LASCAD should work
- Read Beynon-Davies paper p.177
- (p.178 has a cause--effect diagram too)
So what went wrong? p.179
10Context
- 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)
11People 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
12Recommendations 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
