About ISO 18404:2015

Since its inception in 2015, ISO 18404:2015 has provided an internationally recognised benchmark for Lean Six Sigma methodologies.

ISO 18404:2015 defines the approaches organisations are required to have employed to meet the required standards, and very few training organisations around the world are independently accredited to deliver Lean Six Sigma Certifications aligned to ISO18404:2015.

e-Careers is the official training provider nominated by CEPAS, A Bureau Veritas Company to deliver ISO18404:2015 Lean Six Sigma Certifications to individuals across the globe.

Why is there a need for an ISO standard for Lean Six Sigma?

With no universal standard for Lean Six Sigma, training results varied widely between delegates, making it hard for employers to see the true value of an individual and their experience. As many training courses were either uncertified or not certified to a high enough standard, ISO 18404:2015 was introduced to become a strict Lean Six Sigma standard.

What does an ISO 18404:2015 certification mean for me?

Being trained to the strict ISO 18404:2015 standard enables you to confidently explain to others that you meet the single standard of Lean Six Sigma, making you a valuable, highly trained Lean Six Sigma team member. ISO 18404:2015 certification holders are highly sought after, and your certificates will showcase your knowledge and skills to future employers. ISO 18404:2015 certificates are internationally recognised, and your credentials will be published on an online public register, accessible by employers and clients.

Originally, ISO 18404:2015 was a complex and hard standard to achieve. CEPAS, Bureau Veritas and e-Careers has made it both simple and affordable now.

By meeting the ISO 18404:2015 competencies help to make you valuable and employable throughout a wide range of managerial roles in this industry.
