Business case is very important and inseparable part of any project.
Because it includes ‘Project Justification’. Project Sponsor and Board refer to Project Justification at various stages within project. Generally, this part includes justification of spending money on project (Cost/Benefit Analysis).
I think, Cost/Benefit Analysis is just a part of justification. Project team should look at various other facets and refer to tangible and intangible project benefits.
This helps Project Sponsor and Board to look at a big picture.
Consider that in middle of project, Cost/Benefit case does not stack-up. Then, these other justification facets will guide Project Sponsor and Board to take right decision. They may decide to stop or continue project by looking at big picture of project justification.
Refer to Singh’s Business Case Justification Landscape to make a strong justification for your Business case!
