The Regional Development Investment Program (RDIP) is the second phase of the Regional Planning Assistance Project of the Philippine Government and the World Bank/UNDP. The first phase was the preparation of the macro Regional Development Plan (RDP) in each of the country's twelve (12) administrative regions. Hence, the RDIP Project aims at complementing the indicative regional plans with a more operational framework. It is also designed to strengthen the regional development planning process by strengthening the linkages between macro planning, programming and budgeting.
The formulation of the RDIP was piloted in the Central Visayas Region (Region 7) in 1978, and its replication in the rest of the regions began in 1979. All regions now have an RDIP for CYs 1981 to 1985. By virtue of Executive Order No. 589, the RDIP of each region becomes the basis for resource allocation and budgeting of all line agencies and government corporations.
In Region I, the 1981 to 1985 RDIP has been used as the basis for the annual regional budgeting program. However, with the formulation of the 1983 to 1987 Regional Development Plan for the Ilocos Region, this RDIP is now undergoing revision in consonance with the requirements of this new plan.
