    Determine methods and procedures on assignments and system developments for ALS and/or ALS-U through the life cycle of each system including:

    Determine the scope and develop the plan

    Conduct systems analysis and develop the requirements

    Create the system design

    Conduct development work

    Integrate and test prototypes

    Direct the production and installation of power conversion equipment

    Support operations and maintenance of the system
