Stretch Out (A Program)

  1. Procurement: Buying the originally intended number of end items (or close to it) over a longer period (e.g., buying 10 per year rather than 20, which doubles the time of the program).
  2. Acquisition phase or process: taking longer to complete than originally planned, either for technical or funding reasons.
