When reverse engineering a business, what should be defined first?

• A. The market size
• B. The brand identity
• C. The end goal
• D. The mission statement

Answer: (C)

The thing to define first when reverse engineering a business is the end goal—the concrete outcome you want to achieve, such as specific revenue targets, profitability, market position, or impact within a set timeframe. Establishing this target upfront gives you a clear target to build toward, and it guides every subsequent decision: what capabilities you need, what resources to allocate, and what milestones to hit along the way.

Starting with the end goal helps keep the plan coherent. If you jump into market size, branding, or a mission statement first, you risk designing around interests or perceptions rather than actual outcomes. Market size informs viability but doesn’t tell you what success looks like. Brand identity and mission statements are valuable, but they are inputs or expressions of strategy, not the anchor that defines the required business design and path to success. Defining the end goal provides the yardstick against which all choices are measured.
