GSA Professional Services Schedule (PSS)

Contract number: 

The Professional Services Schedule (PSS) is an Indefinite Delivery Indefinite Quantity (IDIQ) multiple award schedule that enables direct access to simple or complex fixed-price or labor-hour professional services. The PSS consists of seven formerly separate schedules that were consolidated in 2015. The contract vehicle gives Dakota the ability provide customized solutions for Federal agency  requirements, such as cybersecurity, management and IT consulting, software engineering, and scientific research, engineering and technical services, using one contract vehicle. Dakota is well-positioned to manage and successfully execute against the multi-disciplinary and customized solutions the PSS schedule provides for acquisition professionals.

F2G is the Dakota-created methodology that enables us to consistently provide on time and on budget delivery of quality services and products that meet client specifications. F2G integrates our ISO 9001:2015 Quality Management System (QMS) and PMBOK project and program management best practices with the structured, process approach of multiple service and product delivery models. Our process also supports our CMMI® Level 2 rating.
