If you only quantify one thing quantify?

• A. Revenue potential
• B. User satisfaction
• C. Market share
• D. Cost of delay

Answer: (D)

When deciding what to work on first, the most informative single measure is the cost of delay. It turns time into economic impact, so you’re not just guessing what something might be worth—you’re seeing how much value is lost each week you wait. The cost of delay blends potential revenue, market opportunities, customer satisfaction, and risk reduction into one urgency-weighted number. That makes it the best metric for prioritization because it directly shows which work loses value the fastest, guiding you to maximize economic value over the time you’d have to wait. In practice, methods like WSJF apply this by comparing cost of delay to the size of the work; the higher the cost per unit of effort, the higher the priority. If you only measure revenue potential, you miss the timing factor; market share and user satisfaction matter, but they don’t alone quantify how quickly delaying erodes value.
