The Methodology page has the most recent versions of the global questionnaires. The Enterprise Survey covers a wide range of business environment topics including general business characteristics, infrastructure and services, sales and supplies, access to finance, degree of competition, land, crime, business-government relations, investment climate constraints, labor, and productivity. There are manufacturing-specific questions as well as a few retail-specific questions. In collaboration with economists in the regional departments of the World Bank, every Enterprise Survey is customized to include economy-specific questions (or region-specific questions). The questions are mostly objective questions aimed at measuring the quality of the business environment and the experience of firms. Less than 10% of the questions are subjective, that is asking the respondent for his/her opinion. The question answers are mostly the following types: yes/no, a percentage or monetary amount, days required to obtain a service, number of times a particular event has occurred, or a 5-point Likert scale.
