“As the world’s leading authority on project management, PMI empowers people to make ideas a reality. Through global advocacy, networking, collaboration, research, and education, PMI prepares organizations and individuals to work smarter in an ever-changing and dynamic world.”
If you want to get into project management or to start leading projects in your organization, then getting a certification from PMI is a must. Everybody knows about the PMP for seasoned project managers, but there are also other certifications with a more specific focus like Agile as an example.
