The correct answer is B. Create the software if you'll use the solution longer than 32 months.. A break-even analysis shows the in-house solution becomes cheaper after 32 months, making it the better choice for longer-term use.
Question
You are the business analyst for your organization and are trying to determine the best solution for an identified problem. You have determined that you could create a software solution using inhouse resources for $65,000 and with an ongoing support of $5,600 per month. A vendor offers you a quote that they can create the software for $49,000 with an ongoing support of $6,100 per month. Which solution should you choose?
Options
- ACreate the software if you'll keep the solution less than 32 months.
- BCreate the software if you'll use the solution longer than 32 months.
- CThere is not enough information to determine which solution is financially better.
- DBuy from the vendor if you'll keep the solution longer than 32 months.

Why each option
A break-even analysis shows the in-house solution becomes cheaper after 32 months, making it the better choice for longer-term use.
Before 32 months the vendor solution has a lower total cost because the in-house upfront premium has not yet been offset by monthly savings, so creating in-house is the wrong choice in that window.
The upfront cost difference is $65,000 - $49,000 = $16,000 more for in-house, but the monthly cost is $500 less ($6,100 - $5,600). Dividing the extra upfront cost by the monthly savings ($16,000 / $500) yields a break-even point of 32 months. Beyond 32 months the cumulative monthly savings exceed the higher initial investment, making the in-house solution the financially superior choice.
There is sufficient information to perform a break-even calculation - initial costs and ongoing monthly costs are provided for both options.
After 32 months the in-house solution is cheaper, not the vendor solution, making buying from the vendor the wrong long-term financial decision.
