Abstract:

Every project has requirements. It doesn't matter if it's building hardware solutions, developing software solutions, installing networks, protecting data, or training users. For the project to be a success, knowing what the requirements are is an absolute must. Requirements exist for virtually any components of a project or task. For example, a project may require specific methods, expertise levels of personnel, or the format of deliverables. This whitepaper will discuss the various kinds of information technology requirements, their importance, the different requirement types, the concept of requirements engineering, and the process for gathering requirements.
