​Below are several metrics Purchasing uses to see how they are doing. The metrics include: On-Time Delivery, Cost Savings and Cycle Time. Included are trends from previous years and some include quarterly graphs showing the progress within the last current fiscal year. If you have any questions, please let us know!

On-Time Delivery 


​On-time delivery is calculated by measuring the receipt of each purchase item against the scheduled due date. The data incorporates goods delivered early and within 5 days after the purchase order date. For FY17 on-time delivery was 90% which exceeds DOE's national target of 84%. This is down from past years by 5% and 4% respectively, but still surpasses the standards set in place by DOE.  

​Cost Savings

Cost savings is calculated by taking the difference between the original cost of a purchase and the amount the order was actually purchased at. If an order costs less money than the original cost, then it is a cost saving. Calculations for cost savings does not include several types of purchases: 

  • ​IWOs/IEWOs - Interagency Work Orders/Inter-Entity Work Orders (orders over $1,000,000 with a sister lab) 
  • MPOs - Memorandum Purchase Orders (orders under $1,000,000 with a sister lab)
  • Iowa State University purchases
  • Credit card purchases


Cycle Time

Cycle time is the time from which we award a requisition to a vender and the time we receive the order, measured in days. The national target for purchases less than or equal to $150,000 is 6-9 days; for purchases greater than $150,000 the goal is 25-30 days; for all purchases combined it's 8-11 days. The lab does a good job staying well below the national targets, yet due to several outlying purchases, Ames Lab did not meet the goal for purchases greater than $150,000 for fiscal year 2017.
