Letters and memos from mayors and the comptrollers were examined at the New York City's archives as well as other relevant information on the city's contracting system, such as data from official government documents including the Mayor's Management Report, information from the Mayor's Office of Contract Services and data provided by the New York City Office of the Comptroller.
Mayor Bloomberg formalized the merger in 2004 with Executive Order 48, which renamed MOC as the Mayor's Office of Contract Services (MOCS).
The rules specified steps in the contracting process that each agency was required to follow in order to have their contracts awarded, from the agency level to the Mayor's Office of Contract Services.
Some examples of the extra steps in the contracting process as a result of the PPB rules are new and more detailed forms to be completed, additional steps in the process and the review and approval of documents by oversight agencies such as the Mayor's Office of Contract Services, the Law Department, the Office of Management and Budget, the Department of Investigations and the Comptroller's Office.
In FY 2004, the average number of calendar days used by each of the oversight agencies (see Table 5) was: 47 for the Law Department, 25 for the Department of Investigations, 15 for the Mayor's Office of Contract Services and 27 for the Comptroller's Office.
Much of these differences related to whether they were current city officials and whether they were in oversight agencies (the Mayor's Office of Contract Services and the Office of the Comptroller) or at city agencies.
The Comptroller can question a contract, suspend a contract for 30 days while asking the Mayor's Office of Contract Services to correct problems associated with the contract, and refuse to register the contract if irregularities are suspected.
David Dinkins gave authority to the Procurement Policy Board to develop comprehensive contracting rules, created the Mayor's Office of Contract Services, had individual city agencies implement the new contracting system and provided training to professionalize the city's contracting staff.
