Final answer:
After the transition to SCRUM, the project coordinator role will be called Scrum Master. This individual will facilitate team interactions, remove impediments, and guide the team in SCRUM principles to maximize productivity.
Step-by-step explanation:
The role of a project coordinator who facilitates interactions, removes impediments, and acts as the team's coach in a SCRUM environment is typically referred to as the Scrum Master. After the company stakeholders decide to transition the software development team to SCRUM, the existing project coordinator would assume this new title and its associated responsibilities. The Scrum Master plays a crucial role in supporting the team, ensuring that the principles of SCRUM are adhered to, and helping to maximize productivity.
