Why is it often difficult to evaluate make-or-buy decisions?

• A. There is no data
• B. Regulatory approvals are required
• C. Most managers don't think it's necessary to do so
• D. There are too many options

Answer: (C)

The main idea here is that the difficulty in evaluating make-or-buy decisions often stems from how decision-makers view the process. If managers don’t think a thorough analysis is necessary, they may skip or skimp on the evaluation, leaving important factors under-examined. A proper make-or-buy study weighs not just obvious costs but also hidden costs like long-term quality, delivery reliability, capacity use, and strategic implications of owning versus outsourcing. When the analysis isn’t given its due importance, data can be incomplete, assumptions go unchecked, and the resulting comparison is fragile or biased, making the decision inherently hard to justify and implement. While data gaps, regulatory hurdles, or many options can complicate specific cases, the most persistent reason the evaluation is difficult is the tendency to undervalue the need for a rigorous analysis.
