It's possible to tag a task with one or more tags during the task's creation. You can also change the tags of a task that has already been created by clicking on the edition symbol. There is no limit on the number of tags that may be added to a task.
The tags allow you to classify an intervention according to different categories defined by yourself. We can tag a preventive operation, electrical, a production stop, and so on. The purpose of the tags is to allow you to analyze and sort out all of your interventions easily. You will be able to generate a list of tasks that have, for example, the tag "production request"; or to show the time spent on preventive interventions for the past month, and so on.
If a tag has been added to an equipment and this has been associated to the task, then the tag will automatically appear on the intervention. However, should you wish to do so, you can easily delete it.
