Weapon System Program Office
The U.S. Government's acquisition office for a — the program manager and the multidisciplinary team behind them. The same program office that manages the system for U.S. forces performs the buy: it works with the case manager to determine the line items, develops the cost and availability estimates, and acquires the articles on contract.
What They Do
An acquisition program manager (PM) is responsible for leading a multidisciplinary team to manage all aspects of an individual acquisition program and for guiding the program toward meeting all cost, schedule, and system performance goals. An acquisition program management team typically includes functional experts from program management, systems engineering, testing, finance, contracting, logistics, information technology, and manufacturing.
The program manager is responsible for formulating the acquisition strategy and executing approved acquisition plans. The program manager typically performs these functions with the assistance of a multidisciplinary support team. Collectively, the program manager, with the respective support team, constitute the program office.
With the support of the system program management office team, the program manager is responsible for leading the program through the remaining phases, decision reviews, and acquisition milestones of the defense acquisition system process. In addition, the program management office remains in place to manage all the technical and life-cycle sustainment aspects of the system after the system is delivered to U.S. forces. The program management office will also be responsible for acquiring any additional quantities for the DOD as well as potentially developing improved or modified configurations.
If the U.S. agrees to sell the system through , the acquisition will be accomplished with support by the same program management office that is managing the system for the DOD. The system program management office may acquire the requirements either as separate individual procurements or by consolidating the requirements with DOD requirements on the same U.S. contract.
For major weapon systems, the Military Departments () establish Program Management (PM) offices responsible for the following:
- Developing and acquiring the initial system
- Managing all technical aspects of the systems delivered to U.S. forces
- Procuring any additional quantities for the DOD
- Engineering improved or modified configurations
An Integrated Product Team (IPT) will typically consist of a program manager, supported by personnel from several functional disciplines (program management, engineering, testing, contracting, logistics, and financial management).
When an international partner decides to acquire a sophisticated through the program, formal logistics support planning begins when the international partner submits a comprehensive , which, in addition to identifying the desired configuration, identifies the country’s operational requirements, and existing logistics support capabilities. However, before the is submitted, there should be informal meetings and discussions between the International partner, the weapon , the , the office, and, potentially, the contractor or manufacturer. These discussions should address the configuration of the product, delivery methods, and how the item is to be sustained.
For major system sales, the case manager must coordinate with program managers and item managers to determine the line items to be included on the case to meet requirements identified in the international partner’s . Cost and availability estimates are developed for all articles and services included in each line. These estimates may be based on current DOD inventories or on information from U.S. defense contractors.
Effective case management requires frequent communication with the program manager, the , and numerous other key personnel in other organizations. When potential cost overruns or delays are identified, the case manager is expected to consult with the program manager, the contractor, and the international partner to ensure all potential options are explored and informed decisions can be made.
Air Force directs the management of its business on a line-by-line basis. or AFSAC, as applicable, assigns line management responsibility to the major command having cognizance over the article or service being provided and a Program Manager () to oversee the development and execution of major system acquisition .
