DTS has recently updated Administrative Rule R895-5 Acquisition of Information Technology. You can see it here. The change is in the definition of small technology purchase:
“Small technology purchases” means a purchase, lease, or rental of hardware, software, and/or technology services that is estimated to be less than $250,000.
The dollar amount was changed from $50,000 to $250,000. This will allow agencies to only complete business cases for purchases of $250,000 or greater.
