Don't Panic: Business Case and ROI Analysis

A business case is a reasoned request to spend resources on a change. It explains the problem, compares ways to solve it, and says how anyone will know whether the promised result happened. The document can be short. Its job is to make a decision inspectable, not to make a spreadsheet look confident.

The first character in this story is the baseline: what happens if no new proposal is approved. Without it, an existing cost can stroll into the benefits column wearing a savings badge. Compare the baseline with a smaller change and a full proposal over the same period. Record only what each option changes. This difference is an incremental effect.

There are five questions behind the case. Why does the change fit the objective? Which option creates the best overall value? Can the required solution be obtained? Can the organization fund the spending when it occurs? Who will deliver it and measure the result? They are called the strategic, economic, commercial, financial, and management cases. One impressive percentage cannot answer all five, however nicely formatted it is.

Return on investment, or ROI, divides net gain by included cost over a stated period. Net present value, or NPV, adjusts future net cash flows to today's value before adding them. The two numbers can tell different stories. ROI is a ratio, so it hides the absolute size and timing of a gain. NPV needs a chosen discount rate and a believable flow of costs and benefits. Neither number pays an upfront bill or proves that people will use the proposed service.

The course's synthetic automation option costs 60,000 to start, then 20,000 each year. It avoids 65,000 in contractor spending each year for three years. The calculated ROI is 62.5 percent, and NPV at an illustrative 10 percent rate is about 51,908. Reduce the avoided spending to 35,000 a year and NPV becomes negative. The arithmetic did not break. The assumption did the heavy lifting all along.

A saved hour is released capacity until an actual budget change or additional output shows what it produced. A benefit also needs an owner, a baseline measure, and a review date. Otherwise approval becomes the last time anyone checks the claim, which is a peculiar way to measure success.

Keep the outcome and its evidence beside the forecast; that is where a business case remains useful after the meeting ends.
