Perfective maintenance involves improving the software's performance, maintainability, or other attributes that are not related to fixing defects. Many systems professionals consider perfective maintenance to be new development because it involves adding new features or enhancing existing ones, rather than simply fixing problems. Preventive maintenance involves activities intended to prevent future problems, but it does not involve new development. Adaptive maintenance involves changing the software to accommodate changes in the environment, which may or may not be new development. Corrective maintenance involves fixing defects, but it is not considered new development because it involves restoring the software to its originally intended state.
