Internal communications
Managers also have to deliver information between upper-level executives and employees. Team members, who are actually working on a project, need to understand what’s required of them and what kind of resources the company is making available. Meanwhile, management wants to know how production is going and whether the staff will finish on schedule.
In this regard, project managers essentially have to act as messengers to ensure that the entire organization is on the same page. Without communication, some people might be working from outdated information that could put a project at risk of complete failure.
