Irrespective of how a project is managed, when an application is released and rolled-out, there can be a nagging question as to whether the application is performing efficiently. In any project, time pressures can force corners to be cut and short-cuts to be taken. At the end of day, if the features are operational and available, things must be ok – mustn’t they ?

In projects based on agile principles, code refactoring can be included, whereby the underlying code of an application’s functionality is reviewed and updated where necessary to make improvements to how an application operates. A proper and regular code review process helps to ensure that technical debt doesn’t build up in an application.
