Oklahoma City, OK - May 13, 2026 - Wichita Tribal Enterprises (WTE), a subsidiary of Quivera Enterprises, has partnered with Diné Development Corporation (DDC) IT Services to support the Indian Health Service (IHS) Office of Information Technology Division of Information Technology (DIT) through software quality and program support services. Together, the team will maintain Software Quality Assurance (SQA) and Software Quality Control (SQC) standards while supporting ongoing efforts to strengthen system performance, reliability, and user experience. "Our team understands that successful software delivery requires more than technical execution alone, " said Gerald Secody, Vice-President at Wichita Tribal Enterprises.
