Asset Management

Table of Authorized Vehicles (TAV)


Each Center shall establish a baseline TAV. This means ensuring only an optimal mix of vehicles is assigned and maintained. Having the right size vehicle fleet is an OMB concern; therefore, Agencies should not miss potential opportunities for savings. The following process/factors should be considered as each Center develops its vehicle baseline:

  1. Require each customer to submit a written justification for each additional assignment using NASA Form 971. Evaluate each submission, focusing on what the vehicle is used for in terms of passenger movement, cargo movement, material movement, or mission essentiality of the vehicle. Look at why requirement can not be met with other means of support; i.e., POV, taxi, bus or pool vehicle. Determine mission impact based on Form 971 input. A decision table is provided that will aid the CTO in determining whether a vehicle should be assigned.

  2. Condition, age, and downtime are factors that should be included in the analysis and documented on the Form 971.

  3. Analyze past and expected utilization: if only 25% of average utilization is currently being met, continued assignment may not be warranted.

  4. Develop preliminary TAV based on evaluation of the data captured on each Form 971, showing current and recommended levels.

  5. Coordinate findings with customers and offer opportunity for rebuttal, especially if recommendation is to reduce assignments.

  6. Consider customer recommendations and then make final decision on baseline mix.

  7. Retain this TAV level and only adjust when mission changes warrant adjustments.

  8. Once the customer baseline TAV is established, develop a baseline TAV for pool vehicles if applicable.


Note: CTO’s who already have an established and approved baseline in place are not required to re-establish the baseline. However, baselines must have been based on measurable and meaningful data.
