Hybrid project management adopts two essential roles from its constituent methodologies. From traditional, Waterfall-related approaches, it takes the idea of a project manager, and from Agile, it brings in the role of scrum master.
How do these two roles interact in hybrid project management? The overall responsibility for managing the project falls to the project manager. The project manager takes full ownership of the success of the project and is also responsible for overseeing effective planning. They define the goals for given time frames, breaking down primary goals and objectives into sub-goals associated with specific components.
Once goals have been established, the project manager works to define the tasks for each component. The project manager appoints a scrum master to manage each sprint and provide details on how they should be implemented. The scrum master can then build their own teams to help fulfil the project needs.
While the project manager takes overall responsibility for the project, they should work closely with the scrum master to effectively break down project phases into clearly defined tasks, and to establish reasonable deadlines and build a working schedule for the project. The scrum master takes point position for the duration of each sprint, and then once the sprint is completed, the project manager steps in to review the sprint results. The project manager then passes their findings and recommendations back to the scrum master, who is responsible for making any necessary improvements to the process before the start of the next sprint.
A simplified way of looking at the relationship between project manager and scrum master is to think of the project manager as primarily associated with front-end tasks, while the scrum master handles essential back-end tasks. So, a project manager would be responsible for things like collecting and organising customer feedback, defining components and setting requirements; the scrum master would take charge of handling development sprints, managing task backlogs and releasing finished products.
