Viewing your use cases
Role: project manager
The Use Cases page displays an overview of all the use cases you are assigned to. The page shows basic information for each use case:

Each use case tile indicates the following:
- the use case name and description
- the number of projects contained in the use case
- the number of datasets resulting from the use case's projects
- the use case progress expressed as the number of tasks completed over all tasks defined
To see the projects belonging to a use case, click its tile. Project managers do this to manage their projects, whereas annotators do this to access their tasks.
Project managers can create new use cases, as well as edit and delete existing ones.
