In project management, the human factor means that the human resources are a factor in the success or the failure of the project.
A motivated, happy, productive, and confident project team can turn a project that will most likely fail into a successful project, and a non motivated, unhappy, non-productive, and a non-confident project team do the complete opposite to projects that will most likely succeed.
The project manager is responsible for the human factor through:
- Motivating his team members
- Ensuring that no team member is over-allocated
- Ensuring that all conflicts are resolved on the spot, and there is no bad blood between team members
- Shield his human resources from the client and from the stakeholders
- Exhibit leadership skills so that team members will "want" to work under him.
- Keep his promises to his team members (breaking a promise is a huge demotivator)
- Provide compassion to his team members when they need compassion
- Treat his team members with respect
In short, the human factor is that the project manager ensures that each one of his team members has satisfied the "Esteem" and the "Self Actualization" part of Maslow's hierarchy of needs.
