"One of the key issues which cause errors in the software development cycle is not having a clear understanding of the requirements for the project. This can be addressed through clear communication and documentation before initiating the project. I've seen the impact on the success of software development through an unrealistic schedule that does not provide enough time for the developers to adequately do their job. Not testing early enough and not performing tests at each stage of the cycle, using the Agile methodology also causes problems. The biggest problem by far which impacts the success of a software development project is clear and frequent communication between all the stakeholders, including the developers, the management team, and the final customer."
