Project Management SaaS, or short PMSaaS, is a web-based tool for project management developed as part of an apprenticeship in computer engineering for application development (as part of advanced education) at the Service Prototyping Lab. The user can create new projects and employee accounts, add work packages and tasks to projects, assign employees to tasks, book hours for them, compare the booked hours to the planned person months, weigh each month differently and add expenses. The project can be edited, shared with other users and archived. To make it easier to keep track of all these things, the tool generates different graphs. This work is a result of exploring how project management can be offered as a service.
