The Integrated Methodology

For Cost-Benefit and Cost-Effectiveness Analysis

Conduct financial, economic, and stakeholders analysis in one model.The methodology used by CRI is Integrated Investment Appraisal (IIA). The Integrated Methodology increases the quality and efficiency of decision making by integrating the various stages of a project appraisal process into one comprehensive model. Using the integrated approach allows the analysts to:

  • Find the overall impact of the project on the economy as a whole.

  • Analyze the value of alternative project designs and financing arrangements.

  • Eliminate the costs associated with conducting separate studies for a single project.

  • Reduce the time required to conduct a complete feasibility study.

  • Measure the risks from alternative points of view.

  • Evaluate the social and budgetary impacts of Public Private Partnerships (PPPs).

  • Correctly integrate the environmental impacts and assign them to the relevant stakeholders.


The strategy behind this approach highlights that any external impact of a project is associated with at least one of its technical transactions. With this transaction focused  approach, all the impacts are directly linked to actual transactions. All the impacts on a stakeholder must be added up to arrive at the net value of the project from that perspective.


The following skills are utilized for construction of an integrated model.

  • Project finance and accounting principles
  • Welfare economics
  • Valuation methods for economic, social, and environmental impacts
  • Risk analysis

These tools are used to integrate the financial and project financing arrangement, social and environmental impacts, and the economic impact on various stakeholders such as the labor and competitors. The integrated approach is the most advanced methodology for evaluating:

  • Major infrastructure projects (energy, transportation, water and sanitation, etc.)
  • Public Private Partnerships (PPPs)
  • Social investment programs (education, health, security, community development, etc.)
  • Environmental conservation programs
  • International development projects
  • Major commercial projects with development impacts
