Step-by-step explanation:
The project manager usually has the greatest ability to affect social and technical success factors of a project during the implementation stage. This is the phase when the project plan is put into action and the project team works to deliver the project's objectives.
During this stage, the project manager is responsible for managing the project team, coordinating tasks, resolving issues, and ensuring that the project is progressing according to plan. They have the authority to make decisions and allocate resources to address social and technical factors that may impact the success of the project.
Project management focuses on planning and organizing a project and its resources. This includes identifying and managing the lifecycle to be used, applying it to the user-centered design process, formulating the project team, and efficiently guiding the team through all phases until project completion.
