why is Project Management certification important?
- to encourage the person to look back and document the experience acquired with projects managed in the past few year,
- to gain access to and learn from standards and best practices in project management when preparing for one of the certifications/exams (PMI®; IPMA; Prince2; ...), i.e. to improve their skills in the many dimensions of project management: managing costs, resources, schedules, suppliers, teams; scheduling activities, negotiating with stakeholders, presentation skills, interpersonal skills, team dynamics, quality management...
- to understand and analyze prior successes and failures in light of the above best practices and establish improvement plans for current and future assignments,
- to acquire a terminology (a common language) together with a more in depth understanding of the project management processes and how they are interlinked. This will be very useful when communicating with project stakeholders and other project managers,
- to join a community of passionate professionals in project management,
- to increase their market value as certified PMs are in high demand,
- to establish their credibility as PMs (internally and externally),
- to progress in the profession,
- to land a job at a company that truly values Project Management.
What's in it for businesses?
businesses should value Project Management certification in order to:
- deliver projects on time, budget and scope with much greater predictability,
- maintain a good level of project management capabilities and experience in the company,
- facilitate PM's recruitment and ensure fastest integration for new hires,
- establish project management development path for internal PMs
- be able to respond to more Requests for Proposal for which certified PMs is a pre-requisite (ISO/IEC 17024 accreditations).

Creates credibility with people who don't personally know you or your work.
It's also a very useful thing to have if your planning on starting your own business, it would also help you get investment if you can plan projects effectively and convince others of your well laid out idea.
thanks, I do think that pmp is very useful for those who are interested in project management
