# Cumulative Optimization Gain

## What is Cumulative Optimization Gain?

Cumulative optimization gain (COG) is a concept used in marketing and operations research to measure the effectiveness of a series of changes or adjustments to a system. It is a measure of how much the overall performance of a system improves as a result of making a series of changes or adjustments. COG is a useful tool for measuring the effects of a series of changes to a system in order to determine whether the adjustments are having a positive or negative effect.

## How is Cumulative Optimization Gain Calculated?

COG is calculated by subtracting the performance of the initial system from the performance of the system after the adjustments have been made. This difference is then divided by the total number of changes made. The result is the cumulative optimization gain.

## Examples of Cumulative Optimization Gain

• A company decides to improve the performance of its website by making a series of small changes to its design and content. After making the changes, the company notices an increase in the number of visitors and conversions. The cumulative optimization gain from the changes can be calculated by subtracting the performance of the initial website from the performance of the improved website, then dividing the result by the total number of changes made.
• A manufacturing company decides to increase the efficiency of its production process by making a series of small changes to its operations. After making the changes, the company notices an increase in the output of its products. The cumulative optimization gain from the changes can be calculated by subtracting the performance of the initial process from the performance of the improved process, then dividing the result by the total number of changes made.
