Additional Information

Engineering Branch Scorecard

Procurement engineers partner with procurement units to develop technical specifications and environmental details on more than 175 procurement contracts. We analyze contracts specifications before the contract goes out to bid and assist in the bid evaluation process to ensure technical requirements are competitive and met. Our time is included in the unit’s cycle time, making our work invisible to customers. However, we track our time to ensure efficiency.
