Agile management is essentially a set of principles that is intended to help employees work more efficiently. Common practices associated with this management style include breaking large goals down into smaller tasks, and daily meetings. When this approach is successful it has the potential to speed up the completion of large projects. However, it often demands that employees deviate from the traditional way that people work.
