The Performance-Based Work Statement (PWS) outlines the implementation and sustainment of the Maintenance Business System Modernization (MABSM) for aircraft maintenance groups at the Warner Robins and Oklahoma City Air Logistics Centers. The PWS covers a variety of services, including project management, implementation of Impresa software, training for users, and ongoing support and sustainment activities. The contractor is responsible for maintaining system accuracy, providing user support, managing configuration changes, and ensuring compliance with quality control measures. Regular training, user guide development, and interface management between the new system and existing Air Force IT systems are crucial. The document emphasizes stringent timelines for reports and updates, including user accounts and error reports. It highlights the importance of security, safety standards, and handling government-furnished property. Compliance with government directives and reporting requirements is critical, establishing a framework for successful contract execution while promoting efficient maintenance practices within the Air Force. This PWS serves as a comprehensive guide for contractors to align their deliverables with the operational and regulatory requirements of the Department of Defense.
