Recount what occurs when there is interdependence between the key business functions.

Interdependence between key business functions refers to the relationship where the output of one process directly affects the input of another. Here's a step-by-step recount of what occurs:

1. Initiation of a Process: The first function in a business starts a process. This could be anything from product development to marketing research.

2. Dependency on Output: The next function in line depends on the output of the previous function. For example, the marketing team depends on the product development team to create a product before they can market it.

3. Effect on Subsequent Processes: The quality and timeliness of the output from the first function directly affects the subsequent processes. If the product development team is late in creating a product, the marketing team will also be late in their marketing campaign.

4. Overall Business Performance: The overall performance of the business is affected by the interdependence of these functions. If one function does not perform well, it can negatively impact the other functions and the overall business performance.

5. Continuous Feedback Loop: There is a continuous feedback loop between these functions. They constantly communicate and adjust their processes based on the performance of the other functions. This helps to improve the overall efficiency and effectiveness of the business.

6. Adaptation and Improvement: Over time, the business learns to adapt and improve its processes based on the interdependence of its functions. This leads to improved business performance and competitiveness.

In conclusion, interdependence between key business functions is crucial for the smooth operation and success of a business. It ensures that all functions are aligned towards the same goal and work together to achieve it.
