According to the PMBOKGuide (Project Management Body of Knowledge), specifically within the Project Resource Management knowledge area and the Develop Team process, interpersonal and team skills are critical for project success.
* Motivation (Option B): In the context of project management, motivation involves providing a reason for someone to act. Project teams are comprised of individuals with diverse backgrounds, expectations, and individual objectives. Factors such as job satisfaction, challenging work, and sufficient financial compensation are classic examples of " motivators " or " hygiene factors " (referencing theories like Maslow ' s Hierarchy of Needs or Herzberg's Two-Factor Theory). The project manager uses these values to empower the team and ensure they remain committed to the project ' s goals.
* Influencing (Option A): This skill is related to the ability to be persuasive and clearly articulating points and positions. While it may lead to motivation, it is more about the act of swaying opinions or sharing power than the underlying values like compensation or job satisfaction.
* Negotiation (Option C): This is a strategy to reach an agreement. While you might negotiate for financial compensation, the " value " itself (the desire for the compensation) is a component of what drives or motivates the individual.
* Trust Building (Option D): This is the process of building confidence through reliability and honesty.
While essential for team cohesion, it is a foundation for communication rather than the specific system of rewards and challenges defined by motivation.
In the PMI framework, a project manager ' s ability to identify what drives each team member (whether it is the challenge of the work or financial rewards) allows them to tailor their leadership style to maximize productivity and team morale.
