London ambulance service computer aided dispatch failure

Selection of a developing organization was further constrained by the requirement that the project be completed in 11 months.

Indeed the defect tracking system still had open issues during the deployment of all three phases. They certainly should have employed full time, experienced, project management and quality assurance teams. This was the crucial mistake that would inevitably doom the project to failure. All other mistakes would likely have been anticipated, prevented, or at least rectified, by a superior software supplier. The paper form would then be physically passed via conveyor belt to central reviewers who would identify and remove duplicate incidents. It got worse as people expecting an ambulance and not getting one began to call back, flooding the already-overwhelmed service. One ambulance crew arrived only to find that the patient had not only died, but his body had been taken away by a mortician [ 2 ] 3. This is an unreasonably low price, especially considering the fact that even after 7. It is hard to understand why the project team made this choice, given that the previous attempt at CAD had resulted in failure, and that the previous failure was due to the "inability of the software supplier to understand the requirements of the system. One might argue that System Options is not responsible for the small window of development time, as it was a restriction imposed by the LAS.

In fact, the system went live without load-testing and with at least 81 known software issues. Given the scope of the requirements, it would have been wiser to award the contract to a larger, more experienced, albeit more expensive, supplier. To make matters worse, computer training had been done 10 months before the system became operational.

The problem was compounded when people called back additional times because the ambulances they were expecting did not arrive. In order for Quality Assurance to be effective, it must be independent of the development organization and empowered to change deadlines when software does not meet quality standards.

With less than 6 months to finish the project, Systems Options began to miss deadlines. It began sending multiple units to some locations and no units to other locations.

LAS management decided to create a new one and proceeded to gather requirements without receiving input from ambulance crews or dispatchers [ 2 ]. Consequently, a new team was assembled to design and build a better system.

Several companies proposed modified deployment schedules in which some functionality would be delivered after the 11 month deadline and the rest a year later.
