Certifications provide frameworks for an organization to follow in managing its processes, so its products or services meet the objectives it has set. The variety of standards adopted, and in many cases used for certification, will vary from company to company, according to the company’s needs and its sector of operation. The plan-do-check-act cycle is the main principle behind these standards. Among the most widely implemented management system standards are ISO 9001, which gives requirements for quality management, and ISO 14001 for environmental management systems. Organisations looking to certify their management systems to ISO 9001 should be using only Accredited Certification Bodies.

At an individual level, certification is to provide official and public recognition of an individual’s competencies and capabilities in a subject area. Professional certification introduces the aspirant to new skills and methodologies, new tools and perspectives and broadens the knowledge base. They also have a financial impact.
