Project Life Cycle

Business Cases

Business cases are reports that explain why a project should be built. They provide evidence to decision-makers, stakeholders, and the public, about how projects can solve problems or address opportunities.  

A business case is just one of several studies Metrolinx uses to make a decision about a project, and helps to establish important details, such as cost, design and benefits, throughout a project’s life cycle. 

Types of Business Cases

Initial Business Cases (IBC) determine the best option for a project based on several factors. We think about how the project will help us reach our transportation goals for the region, the overall economic value and potential cost-savings, and environmental benefits. We also consider what is needed to build and operate the project once it’s in service. 

Preliminary Design Business Cases (PDBC) build on the previous IBC and are typically used to secure government funding for procurement and construction. We further analyze the preferred option, weigh the benefits and risks, and explore ways to successfully implement the project.   

Full Business Cases (FBC) document project design, needs and benefits at the procurement stage, and give us a better picture of the preferred project option. For larger, long-term projects, we may update the FBC to include new information that we learn over the course of the project’s life cycle. 

Post In-Service Business Cases may be developed after a project is complete and in-service to study the benefits and costs, and to identify lessons learned and opportunities for improvements for future projects.
