Simply put, project success occurs when outcomes add value to the business. The value of a project is defined by subtracting all costs from all benefits the project delivers.
Using this logic, when your expected project benefits are $3 million and your company wants a return on investment (ROI) on each invested dollar of 50%, your project budget is $2 million. In other words, project budget = project benefits / 1.5.
If the expected benefits of your project go down, your project budget should go down. It is that simple.
Many people confuse the real project budget with the authorized project budget. The authorized project budget is the total amount of authorized financial resources allocated for the particular purpose(s) of the sponsored project for a specific period of time. It is usually based on a mixture of project cost estimations, department budgets, free cash flow, and other factors.
But as soon as your costs go over the authorized project budget (which is highly likely for technology projects), or the expected benefits are not as big as planned (highly likely as well) you should ask yourself what the real budget of your project is and if you are willing to spend it or not.
How do you know whether you’re looking at the right factors when it comes to determining the real budget?
Whether or not your company can spend this money is a financing and risk question, not a budget question. You could even secure a loan to do certain projects. This increases risk and reduces ROI (because of paid interest) but can be a valid option.
Whether or not this budget is enough to realize the project is a cost estimation and risk question, not a budget question. You should never confuse your cost estimations with your budget. Budget is what you can spend, while cost estimation is what you think you will spend. Ideally, the latter is less than the former.
And whether or not your organization is willing to spend their money on this project is a prioritization question, not a budget question.
In a nutshell: Always express your project budget in terms of expected benefits delivered and you’ll have a better idea of the real budget of your project.
