Cost-Benefit Analysis (CBA) is a financial evaluation tool used in project management to assess the feasibility of a decision or course of action by comparing the total expected costs against the anticipated benefits. While the specific “nine phases” of CBA consult methodology are not detailed in the sources I found, I can provide a summary of the general process involved in CBA, which typically includes the following key steps:

1. Data Collection: Gathering all relevant information about the project’s costs and benefits.

2. Analysis: Calculating and comparing the total costs and benefits.

3. Decision-Making: Based on the analysis, determining if the benefits outweigh the costs and if the project is viable.

4. Reporting: Communicating the results of the CBA to stakeholders for informed decision-making.

These steps ensure that project managers and stakeholders understand if a project is viable, profitable, and worth the investment. It’s a method that helps in making better, more cost-effective project decisions¹².

Additionally, CBA can be integrated into various project management methodologies, such as Agile or Waterfall, and is also useful in project risk management and decision-making frameworks¹.

If you’re looking for a more detailed breakdown into nine specific phases, it might be helpful to consult a specialized resource or expert in CBA methodology.
