Research conducted by two Oxford academics (Why Your IT Project May Be RiskierThan You Think) has suggested that the private sector has almost as much difficulty managing big software projects as the public sector. It also indicated that some types of projects have put companies’ survival at risk.
Whereas government departments can experience almost permanent revolution, private sector processes, in general, remain fairly stable. So it’s depressing to learn one in six of the projects they studied was a “black swan” – with a cost overruns of 200%.
The causes include: technology that doesn’t work, the difficulty in accommodating the exception cases, managing large teams, changes to the scope of the project, dealing with legacy systems, changes in legislation, and failing to build a system that meets the users’ requirements.
The researchers recommend breaking projects into smaller, more manageable units and using the best possible forecasting techniques.
There’s an additional problem: systems that work technically can still fail. If the user does not understand how to use the system, or if they don’t understand the benefits of using it, your “successful” system can end up under-used. User Assistance (online Help, Getting Started guides, screencasts and so on) mustn’t be forgotten. It’s one of those final steps in a truly successful project.
