Viva Engage helps promote employee relationships and communication. Due to this activity, widespread Engage usage might have a beneficial effect on employees' mutual engagement, and even on whether they stay with the company. Engage measures this phenomenon, which is called employee retention.
The Network Analytics dashboard shows a Viva Engage employee retention metric. It shows the difference in 28-day retention rates between Viva Engage users and nonusers. Since Viva Engage doesn’t have access to customer human resources data, Engage uses Microsoft 365 data to determine whether an employee is retained. Retention is based on whether they have a working Microsoft 365 account and actively use that account.
Note
Only Engage network admins and corporate communicators have access to the Network Analytics dashboard.
Employee groupings
Engage defines the employee population for which to calculate retention. It classifies employees into two groups based on Viva Engage and Microsoft 365 usage behavior for an 84-day (~three month) period.
Active on Engage: Employees who perform an action in Viva Engage. Actions can include viewing, writing, or reacting within any Viva Engage platform.
Not active on Engage: Employees with active accounts but who don’t perform an action in Viva Engage.
Retention proxy
As noted, Engage doesn't access customer HR information, so it uses a retention proxy to track employee retention. It infers the approximate date an employee left their company by using one of the following conditions:
- Deletion of a Microsoft 365 account;
- The user doesn't use a Microsoft 365 app in the previous 28 days.
Because the retention proxy relies on inactivity for at least 28 days, Engage's retention metric waits another 28 days after the calculation period before it confirms inactivity.
Calculation and comparison
For each employee group (Active on Engage and Not Active on Engage), Engage also measures the share of retained accounts in the following 28 days. The chart in the Network Analytics dashboard is the percentage point difference in retention rates between active Engage users, and inactive Engage users.
Example
The following example shows the retention metric calculation.
| Three stages of data collection | Details |
|---|---|
| Population collection period (84 days) Jan 1 - Mar 25 |
1,000 employees have active Viva Engage accounts. 800 appear as Active on Engage and 200 appear as Not Active on Engage. |
| Evaluation period (28 days) Mar 26 - Apr 22 |
The Eval period counts deleted Microsoft 365 accounts and accounts with a final Microsoft 365 action. |
| Inactivity verification period (28 days) Apr 23 - May 20 |
To verify an employee’s last action, Engage views their activity for the following 28 days to ensure no more activity occurs. |
For all employees counted in the full 84 days (the population collection period), 40 Active on Engage employees aren't retained. Twenty Not Active on Engage employees aren't retained.
After the stages elapse, the following difference in retention rates for this cohort is shown in the Network Analytics dashboard:
95% retention for Active on Engage employees (760/800 = 95%)
90% retention for Not Active on Engage employees (180/200 = 90%)
In the Network Analytics dashboard, the Retention metric shows +5.0 percentage points (95% - 90%).
