## KPIs

Below is a description of the **KPIs** that are displayed on the top.

| KPI | Description |
| --- | --- |
| Closed cases | Cases that ended with a *close activity* and started with an *open activity*. |
| Open cases | The cases that did not end with a *close activity* and started with an *open activity*. |
| Incorrect start cases | The cases that did not start with an *open activity*. |

## Dashboards charts

Below is a description of the dashboard charts of the **Overview - Open/Close** dashboard.

| Chart | Description |
| --- | --- |
| First event | Displays the number and percentage of cases per first event. |
| History (first event) | Displays the history of the number and percentage of cases per first event. |
| Last event | Displays the number and percentage of cases per last event. |
| History (last event) | Displays the history of the number and percentage of cases per last event. |

When there is not a clear answer on the question which activities might be the open/close activities, the information on the **History** charts help you to draw conclusions. Below is a description of typical situations for close and open activities.

### Close activity

When a graph of an activity is stable over time and the percentage is high, the activity often is the last activity of a case. This means it probably should be a close activity.

When a graph has a spike at the end, this probably means that it is the last activity of cases that are not resolved yet, and it is not a close activity.

### Open activity

When a graph of an activity is stable over time and the percentage is high, the activity often is the first activity of a case. This means it probably should be an open activity.

When a graph has a spike at the start, this probably means that it is the first activity of cases that have been cut in your data, and it is not an open activity.
