  RESPONSIBILITY ASSIGNMENT MATRIX (RAM)





A structure called the Responsibility Assignment Matrix (RAM) is developed by integrating the Organization Breakdown Structure (OBS) with the Contract Work Breakdown Structure (CWBS). This matrix displays the CWBS on one axis and the OBS on the second axis.

The proper integration of the two structures (CWBS and OBS) into the RAM will create a home for each work statement of the contract and provide a disciplined framework so that organizing, planning, budgeting, measurement monitoring, and reporting of the performance measurement can be correctly implemented. Each intersection point on the RAM defines a possible requirement for one or more specific scopes of contractual work to be performed by the responsible functional organization. This intersection point, envisioned as a third axis within the RAM, defines a point where one or more Task Plans may be formed and a point at which work is organized, scheduled, budgeted and its progress monitored, measured and reported. The fourth axis of the RAM when properly implemented allows for the use of a unique Task Plan for each phase of the contract as it progresses through time.

By inserting the budgets defined for each Task Plan into the designated location of the RAM the "Dollarized" RAM is created. This budget information is normally summed beginning from the Task Plan level through each level of the RAM. The information is displayed for audit purposes during System Implementation reviews for the customer. The dollarized RAM is a mechanical method of footing and cross footing all of the distributed budgets to assure the Project Management Office that the budgets have been properly allocated.

This illustrates an example of RAM
