The letter sent to vendors upon approval to the QVL indicates the effective dates. Acquisition of IT professional services is decentralized. Each department is responsible for accessing the QVL and soliciting quotes from those vendors whose service offerings most closely match services needed. It does not, however, preclude a department from issuing a RFP for a major or complex procurement of services. Because of decentralization, there is no one person who is aware of all IT professional services opportunities throughout the city.
Many departments have several IT professionals managing their IT functions.
As there are over 25 service categories on the QVL, typically no one person in each department manages all services. Yes, but opportunities are limited. Departments can choose not to utilize the QVL and issue a separate RFP for IT professional services. In rare instances, departments may be able to justify a sole source vendor selection.
