LASCAD
On 26 October 1992 the London Ambulance Service started to use a new computer-assisted dispatch (CAD) system, known as LASCAD. Poorly designed and implemented, its introduction led to significant delays in the assigning of ambulances, with anecdotal reports of 11-hour waits. Media reports at the time claimed that up to 30 people may have died as a result of the chaos, despite a lack of evidence. The then-chief executive, John Wilby, resigned shortly afterwards. This failure is often cited in case studies of poor engineering management.

London Ambulance Service
The London Ambulance Service NHS Trust (LAS) is an NHS trust responsible for operating ambulances and answering and responding to urgent and emergency medical situations within the London region of England. The service responds to 999 phone calls across the region, and 111 phone calls from certain parts, providing triage and advice to enable an appropriate level of response. It is one of the busiest ambulance services in the world, and the busiest in the United Kingdom, providing care to more than 8.6million people, who live and work in London. The service is currently under the leadership of chief executive Daniel Elkeles and chair Andrew Trotter OBE QPM. The service employs around 5,300 staff. It is one of ten ambulance services trusts in England providing emergency medical services, and is part of the National Health Service, receiving direct government funding for its role. The LAS responded to over 2.1million 999 calls for assistance, and over 1.2million incidents in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Failed And Overbudget Custom Software Projects
This is a list of notable custom software projects which have significantly failed to achieve some or all of their objectives, either temporarily or permanently, and/or have suffered from significant cost overruns. For a list of ''successful'' major custom software projects, see Custom software#Major project successes. Note that failed projects, and projects running over budget, are not necessarily the sole fault of the employees or businesses creating the software. In some cases, problems may be due partly to problems with the purchasing organisation, including poor requirements, over-ambitious requirements, unnecessary requirements, poor contract drafting, poor contract management, poor end-user training, or poor operational management. Permanent failures Because software, unlike a major civil engineering construction project, is often easy and cheap to change after it has been constructed, a piece of custom software that fails to deliver on its objectives may sometimes be m ...

Computer-assisted Dispatch
Computer-aided dispatch (CAD), also called computer-assisted dispatch, is a method of dispatching taxicabs, couriers, field service technicians, mass transit vehicles or emergency services assisted by computer. It can either be used to send messages to the dispatchee via a mobile data terminal (MDT) and/or used to store and retrieve data (i.e. radio logs, field interviews, client information, schedules, etc.). A dispatcher may announce the call details to field units over a two-way radio. Some systems communicate using a two-way radio system's selective calling features. CAD systems may send text messages with call-for-service details to alphanumeric pagers or wireless telephony text services like SMS. The central idea is that persons in a dispatch center are able to easily view and understand the status of all units being dispatched. CAD provides displays and tools so that the dispatcher has an opportunity to handle calls-for-service as efficiently as possible. CAD typically con ...

Software Crisis
Software crisis is a term used in the early days of computing science for the difficulty of writing useful and efficient computer programs in the required time. The software crisis was due to the rapid increases in computer power and the complexity of the problems that could not be tackled. With the increase in the complexity of the software, many software problems arose because existing methods were inadequate. The term "software crisis" was coined by some attendees at the first NATO Software Engineering Conference in 1968 at Garmisch, Germany. Edsger Dijkstra's 1972 Turing Award Lecture makes reference to this same problem: The causes of the software crisis were linked to the overall complexity of hardware and the software development process. The crisis manifested itself in several ways: * Projects running over-budget * Projects running over-time * Software was very inefficient * Software was of low quality * Software often did not meet requirements * Projects were unmanagea ...
