A knock-on effect refers to the indirect or secondary consequences triggered by a specific action, event, or decision. In business and sales, it describes a chain reaction where one change causes another, often in unexpected ways.

For example:

• Launching a new product might create a knock-on effect on support resources, as more inquiries come in.
• A pricing change in one market can lead to a knock-on effect on competitor behavior or customer expectations elsewhere.

The term is often used to emphasize the importance of considering not just the immediate outcome, but also how that outcome might ripple across other teams, systems, or metrics.
