Which statement defines scalability?

• A. Ability to grow without a commensurate increase in cost.
• B. Requires proportional increases in cost with growth.
• C. Only depends on marketing reach.
• D. Managed solely by increasing headcount.

Answer: (A)

Scalability means your business or system can grow to meet higher demand without a proportional rise in cost. That definition matches the idea of handling more output or customers while keeping expenses largely the same, thanks to reusable processes, automation, and flexible resources. When growth comes with costs that rise in tandem with volume, you don’t gain efficiency or economic advantage from scaling. Merely expanding marketing reach doesn’t ensure you can support more demand cost-effectively, and increasing headcount alone tends to raise costs without automatically improving capacity or efficiency.
