    • There is an exam for each chapter of the self-study guide. Upon completing a chapter, the candidate has to take a short online exam that consists of approximately 10-15 questions. These exams are non-timed and open-book and can be taken any day at any time.

    What are the Roles and Responsibilities of a Six Sigma Yellow Belt?

    A Yellow Belt professional is expected to know how to integrate the methodologies of Six Sigma to improve transactional systems and production for meeting of organization objectives and customer expectations better.

    For a project, Yellow Belts participate as core team members. They often have the responsibility of running small process improvement projects with the use of PDCA. With the help of PDCA, a Yellow Belt can identify a process that could benefit improvement. These small projects can get escalated to the level of Black Belt or Green Belt, where the use of DMAIC methodology is done for maximizing cost savings with the use of Statistical Process Control.

    Preparation for Six Sigma Yellow Belt introduces the basic tools of Six Sigma and process management. This provides candidates with a better knowledge of processes, allowing them to provide the necessary assistance to achieve the overall objectives of the organization. They get an overview of the methodology, allowing them to be aligned with the intentions and goals of the company. They have sufficient knowledge to assist Black and Green Belts with their projects.

    What are the benefits of Lean Six Sigma Yellow Belt?

    A lot of people wish to get certified at the highest level, which is why they directly skip to the Black Belt. While this approach is not necessarily wrong, earning a Yellow Belt has its benefits that include:

    Better understanding of the roles

    For getting Black Belt, it is important to understand the Green belt and Yellow belt roles as well. The exam is particularly aimed at the Yellow Belt level. It will provide you with an overview of the specific tasks performed by Yellow Belts for a project. They do not have the statistical abilities of a Green Belt, so it is not expected of them to perform such tasks. However, yellow belts do understand the basic Six Sigma principles such as y=f(x), Process Variances, DMADV variation, ISO, Needs Analysis, and more.

    Great for your resume

    It is not necessary to have a high-level credential in Six Sigma. With a Six Sigma Yellow Belt on your resume, you show your employers that you are dedicated towards the DMAIC process and have passed the exam to ensure quality. Employers are always looking for employees to know how to minimize wastage and save money. Even having your Six Sigma belts listed on LinkedIn will earn you more visibility as it allows employers to search for people with the traits they need.

    Potential for high salary

    Earning the certification doesn’t necessarily guarantee you a higher salary, but it does make you a more valuable employee to your employer. Amidst such high competition, employers are always on the lookout for candidates with varying skill sets. They will always value someone who can get more tasks done. Your Yellow Belt will certainly give you an advantage over those who don’t have Six Sigma certification.

    Of course, apart from the above-mentioned benefits, there are other reasons to get it as well. One great reason is that you get to learn something new and develop your skills to a great extent. Regardless, having the Yellow Belt is beneficial for yourself and your organization.
