Final answer:
Superior-subordinate relationships in project management are no longer strictly hierarchical due to the shift towards more collaborative and equal partnerships.
Step-by-step explanation:
In project management, the statement 'In project management, superior-subordinate relationships are known and lines of authority are clear' is False.
Traditional hierarchies in project management have been shifting towards a more collaborative and equal partnership between managers and employees. Organizations are adopting flatter organizational structures, where teamwork and open communication are encouraged. This means that lines of authority may not always be clear, and superior-subordinate relationships may be more collegial and cooperative rather than strictly hierarchical.
For example, it is becoming more common for higher-level managers to seek feedback and input from entry-level employees, and for employees to contribute value to the organization and team. This trend recognizes the benefits of shared decision-making and the importance of engaging employees at all levels for the overall success of the project.
