Research shows that investment promotion agencies (IPAs) may be the best public institutions to meet government objectives for attracting, establishing, retaining, expanding, and linking productive private investment. As part of this, IPAs need to provide relevant, high-quality services to investors at different stages of the investment life cycle. Informed by its research and experience in global operations, the World Bank Group introduces the Comprehensive Investor Services Framework (CISF), a catalog of specific services to meet investor needs. IPAs can use this investor-centric framework to design service offerings in line with their strategic focus and promotion capacity.
