# Performers and Roles

 The *BPM Execution Engine* take the lanes of *Bizagi* and turn them into roles inside the Application.\
 Using lanes to define roles has many advantages but has one drawback. A task will only have one role.\
\
 If there is a task that require more than one role then Performers can be used. Performers are also roles but they are defined differently in Bizagi. A task can accept more than one Performer.\
 The rule is:

* **If a Task Definition in Bizagi require more than one role then use** **Performers**
* If a Task has performers then the lane is ignored
* *If a initial task has Performers only the **first** performer will be allowed to create the process instance*

 To add Performers open the properties windows of a Task (in Bizagi) and click on Performers.\
\
 1- Selected Task in Bizagi\
\
 2- Resources list of selected Task\
\
 3- Modify Resources list of selected Task\
\
 4- Create a role as a Performer\
 Create a new resource selecting the Type: "Role" (type "Entity" is not used). This will be a Performer for the selected task. The number of Performers must be greater than 1 if not (0 or 1) the Performer will be ignored and the role will be taken from the lane.
