You can only add a new project if you are process admin or project creator.
You can add a new project from the pipeline or from the project list view. There is no difference between the projects created in the pipeline and the ones created in the project list.
1- Locate the “+ Project” button on top of the pipeline or the project list.
2- When you click on the button, the Create New Project window will appear.
3- Give the project a title and fill in the start date. You can also create a project using a template that you have created. Learn more about this feature in What is a project template. Once the form is completed, click “Create Project”.
4- It may take a few moments for the project to be created. When the process is finished, the new project will be highlighted on the pipeline or the project list.
