Top 5 Reasons to Earn a Lean Certification

By Thom Mandl, Guest Contributor for Transformation Advisors

Certifications Demonstrate Expertise

Professional certifications can cost hundreds and sometimes even thousands of dollars. Perhaps even more importantly, they often require a significant investment of time and energy – both of which are in short supply for busy professionals.

As both an employer and job seeker, I am convinced the right certifications play an important role in hiring, promotion, and ultimately performance.

Professional certifications demonstrate expertise and are one of the best credentials you can obtain. They testify to proficiency in a particular skill or field, which can make you a more attractive candidate, enable superior job performance, and lead to career advancement.

The top reasons for earning a professional certification are:

  1. Skills and Knowledge Validation
  2. Competitive Advantage
  3. Career Advancement
  4. Compensation Enhancement
  5. Networking and Community

Let’s look closer at each reason:

1. Skills and Knowledge Validation

Earning a certification indicates you have met specific standards and possess a certain level of knowledge and skills. It provides third-party validation of your abilities, which can be valuable when applying for jobs.

For example, some organizations require certification in Lean, Supply Chain Management, or Project Management to weed out candidates who have simply picked up a few buzzwords, but do not understand the improvement methodology and could not effectively lead a project.

Someone without a lean certification may claim to “know” lean, when in reality, they don’t know the 5 principles of lean, how to run a kaizen blitz event, or create a value stream map. All are key skills and knowledge required at organizations making a lean transformation.

Third-party validation of skills from a professional certification is far more powerful than self-promotion and helps mitigate risk for employers.

2. Competitive Advantage

Certifications give you an edge over other candidates who do not possess them. They showcase your commitment to continuous learning and professional development. Certifications also reduce the risk associated with hiring for a particular skill, since it can be difficult to determine a candidate’s level of competency during the interview process.

As an employer, I look for people who have demonstrated they are lifelong learners and who will continue to grow their knowledge and skills to meet the evolving needs of the company.

Many universities provide the opportunity for students to earn a degree and professional certifications at the same time. The award winning MBA in Project Management program at Louisiana State University Shreveport offers Certified Lean Practitioner as part of a Lean Transformation class and Certified Six Sigma Green Belt as part of a Process Improvement class. Having a degree and professional certifications is a competitive advantage.

For those without college degrees, research from the Burning Glass Institute reveals a number of organizations are reacting to worker shortages by dropping college degree requirements for many middle-skill jobs. These employers are “evaluating applicants on their demonstrated skills and aptitudes, rather than on their level of academic attainment…” They go on to estimate “1.4 million jobs could open up to workers without college degrees over the next five years.” A professional certification can go a long way toward showing the documented skills which these employers will be looking for.

3. Career Advancement

Many organizations consider certifications when making decisions about promotions and career advancement. Certifications demonstrate expertise, open new opportunities, and allow you to take on more significant responsibilities.

For example, as part of the Lean Transformation at one company, one of my engineers who had earned the Certified Lean Practitioner designation was promoted to an Operations Excellence role.

If an organization is committed to lean, six sigma, agile, sustainability, or any other worthwhile endeavor, then earning a relevant certification demonstrates expertise and signals you are all-in. You will demonstrate you have current skills and knowledge for the tasks at-hand.

Don’t sit back and wait for something to happen. Promotions go to those who rush in and announce they are ready to take action.

4. Compensation Enhancement

Certifications can positively impact your earning potential. Some employers offer higher salaries to employees who hold relevant certifications due to their increased expertise and value to the organization. Data from the United States Department of Labor reveals those with a certification in “management, business, and financial operations” jobs make 31% more than those without a certification.

In one of the companies I led, an employee took the initiative to earn a Certificate in International Trade to meet the growing export needs of our business. This achievement led to his promotion and a substantial wage increase.

Higher salaries are also a function of demand and supply. If a job requires a certification, then there will be fewer people who meet the requirements. Data from the United States Department of Labor reveals only 2.4% of full time workers in the civilian labor force have a professional certification. For many skills, the demand is high and the supply is low.

5. Networking and Community

Pursuing and maintaining certifications often involves engaging with a community of professionals in your field. This can provide you with valuable networking opportunities and access to industry events, where you can keep current with emerging trends. The best and most engaged people will be collaborating at conferences and similar community events. This collaboration drives new and better ways into the DNA of the body of knowledge associated with the certification.

Belonging to a community is a two-way street. While you sharpen your skills and pick up new ideas, you will also be giving back. Sharing your successes and challenges is just as rewarding as learning from others.

As an example, the certification I earned in supply chain management led to an invitation to join the Board of Directors of the Association for Supply Chain Management Northern Colorado. Beyond the benefits of taking a leadership role for a non-profit professional organization, I also made many long-term friendships.


Make no mistake. Professional certifications demonstrate expertise and are one of the best credentials you can obtain.

They demonstrate you are a serious professional who has invested in acquiring the skills and knowledge required to help any organization succeed.

In addition, earning a high quality professional certification will give you a competitive advantage over those who cannot demonstrate they take continuous education seriously. You will find the doors open for career advancement and higher compensation.

You will feel great about yourself, rewarded for your hard work, and find yourself in a community of like-minded professionals.

Be in the 2.4% of workers with a certification.
