Calculating the digital experience score
Digital experience score is the weighted average of device experience score and application experience score for all employees. The formula used to calculate the digital experience score is:
Formula
Weighted Average = Sum of (Score * Weight) / Sum of Weightswhere,
- Score: Device experience score and application experience score
- Weight: Weight given to each contributing factor's score This score is rounded off to the nearest whole number.
Score range definition
The following defines the score range and its corresponding classification:
- Good if the score is greater than 75
- Average if the score is from 45 through 75
- Poor if the score is less than 45
- Example
Consider the following values for the contributing factors:
- Application experience: Score = 55 and Weight = 50
- Device experience: Score = 54 and Weight = 50 Then the overall digital experience score is calculated as:
Digital experience score =
(55x50 + 54x50)/ (50+50)= 54
Calculating the application experience score
Application experience score is calculated as the average of the experience scores of all the applications. The experience score of an individual application is calculated by combining three scores: application health metric, user sentiment, and service experience. Each of these scores is given a weight, and then they're averaged together. The formula for the application experience score is:
Formula
Weighted Average = Sum of (Score * Weight) / Sum of Weightswhere,
- Score: Application health metrics score, user sentiment score, and service experience score
- Weight: Weight given to each contributing factor's score
- Score range definition
The following defines the score range and its corresponding classification:
- Good if the score is greater than 75
- Average if the score is from 45 through 75
- Poor if the score is less than 45
- Example
Consider the following values for the contributing factors:
Contributing factor Score Weight Application health metrics 55/100 50 User sentiment 58/100 30 Service experience 72/100 20 Then the application experience score is calculated as:
Application experience score =
(55x50 + 58x30 + 72x20) / (50+30+20)= 59 (rounded off).
Calculating the device experience score
Device experience score is calculated as the average of the experience scores of all the devices across all device groups. The experience score of an individual device is calculated by combining three scores: device health, user sentiment, and service experience. Each of these scores is given a weight, and then they're averaged together. The formula for the device experience score is:
Formula
Weighted Average = Sum of (Score * Weight) / Sum of Weightswhere,
- Score: Device health metrics score, user sentiment score, and service experience score
- Weight: Weight given to each contributing factor's score
- Score range definition
The following defines the score range and its corresponding classification:
- Good if the score is greater than 75
- Average if the score is from 45 through 75
- Poor if the score is less than 45
- Example
Consider the following values for the contributing factors:
Contributing factor Score Weight Device health metrics 64/100 50 User sentiment 68/100 30 Service experience 70/100 20 Then the device experience score is calculated as:
Device experience score =
(64x50 + 68x30 + 70x20) / (50+30+20)= 66 (rounded off).
Application experience metrics
| Metric | Description |
|---|---|
| Application health metrics score | An application's health metrics score is a weighted average of the normalized values of multiple metrics, including CPU usage, memory usage, and crash reports. These metrics are tracked across all relevant devices. |
| User sentiment score | An application's user sentiment score is the average of the normalized sentiment scores obtained from user feedback collected for that application. |
| Service experience score | The service experience score for an application is the weighted average of normalized incident metric scores based on all the incidents resolved for the application. |
Device experience metrics
| Metric | Description |
|---|---|
| Device health metrics score | The device health metrics score for each device group is computed as the weighted average of all normalized metric scores of that device group. |
| User sentiment score | The user sentiment score for each device group is the average of the normalized sentiment scores. The scores are collected from user feedback for the devices in the group. |
| Service experience score | The service experience score for each device group is the weighted average of normalized incident metric scores. The scores are based on all the incidents resolved for the devices in the group. |
