2. Deepen Your LeSS Knowledge

Required Reading

To fully grasp LeSS and its related principles, immerse yourself in the core LeSS books and other recommended materials. This foundational knowledge is crucial for any aspiring trainer. Through these readings, a trainer should be able to precisely and thoroughly describe the LeSS rules, framework and guides and experiments.

Read the LeSS Site
Mandatory Books

The following books are mandatory reading for every LeSS trainer

Additional reading

The following reading is, optional, but highly recommended.

Attend Bas and Craig’s Practitioner Course

Engage in the course just like any other participant, immersing yourself fully in the learning experience.

At the end of each day, there might be a debriefing session with Bas or Craig. During these sessions, you’ll be encouraged to provide a summary of your daily insights and learnings, deepening your understanding and reflection of the course material.

Facilitating the Growth of Candidate Trainers

To support those on their journey to becoming trainers, we offer the following opportunities:

  • Reserved Seats in Public Classes: In each public class led by Bas and Craig, we reserve three seats exclusively for candidate trainers, at no cost. Bas and Craig strive to conduct regular courses across various regions including the US, Europe, and Asia.
  • Participation in both Bas and Craig’s Courses: We encourage candidates to experience courses from both Bas and Craig, as each class brings a quite different perspective and teaching style.
  • Opportunity to Co-Organize a Class: We welcome and support the co-organization of classes. This collaboration not only aids in your participation but also deepens your involvement in the LeSS community. This makes it easier to do the participation when Bas and Craig are not frequently near your location.

Advancing to the Next Phase: Join the Candidate Trainer Community

Upon fulfilling the initial requirements – completing the recommended readings and participating in both Craig and Bas’s Certified LeSS Practitioner Courses – you are ready to progress to the next stage of your journey.

  • Earning the “Candidate Trainer” Badge: Reach out to us at Upon verification, we will honor your progress by adding the “Candidate Trainer” badge to your profile, symbolizing your commitment and achievements.

  • Invitation to Candidate Trainer Meetings: As a candidate trainer, you will receive an exclusive invitations, to a special meeting held on the eve of the LeSS Conference and other community organized Trainer events. A perfect opportunity for networking, learning, and collaboration with fellow aspirants.

3. Document Your Experience and get a Mentor

The next step is to reflect on your LeSS experiences by writing a thorough case study. Then, seek a mentor from our pool of experienced trainers to guide you through your journey.


The hardest and most time consuming part of this step is to get real experience and write them down in a case study.

If you are currently involved in a LeSS adoption and want to write a case study about it, or you already have the experience and ‘just’ need to write them down, then you are ready to get a mentor. A mentor is an existing LeSS trainer who will help you in your growth, reflection, and in writing your case study.

You can learn more about what to expect from mentoring from the mentoring guidelines. These guidelines are to clarify the expectations for the candidate trainer and to support the mentor in the mentoring process.

If you are at this stage, please mail to request for a mentor and share any preferences you might have.

Crafting Your Experience Report (Case Study)

Your journey and insights are invaluable to the LeSS community. We encourage you to share your experience in the form of a case study, aiming for publication on the site and potentially on other renowned platforms like InfoQ or ScrumAlliance.

  • Realistic and Honest Descriptions: Your case study should reflect the real-world complexities of major organizational changes. We value authentic accounts that include the challenges, compromises, and difficult decisions made during the process. Prevent “sugar-coated” descriptions.
  • Learning from Difficulties: A key aspect of your report should be the exploration of problems encountered and how they were addressed. Such candid narratives provide profound learning opportunities for readers and fellow practitioners.
Inspirational Case Study Examples

For inspiration and a clearer understanding of what constitutes a thorough and effective case study, explore existing case studies on the LeSS website. These examples illustrate the depth and detail we’re looking for in your submissions.

Case Study Submission Standards

To ensure your case study effectively communicates your experience and insights, please adhere to the following requirements:

  • Quality and Clarity: The case study should be well-written, with a clear narrative that reflects a high standard of professionalism.
  • Length: A minimum of 1000 words to provide a comprehensive overview of your experience.
  • Visuals: Including photos from the adoption process is highly encouraged, as they add depth and context to your narrative.
  • Further Guidance: For a more detailed understanding of what we expect in a case study, please review our Case Study Guidelines.
Suggested Topics for Your Case Study

To guide your writing process and ensure a comprehensive case study, consider covering the following topics:

  • Product Overview: Begin with a summary of the product involved in the LeSS adoption.
  • Motivation for Change: Discuss the driving forces and context that necessitated the shift to the change.
  • Introduction to LeSS: Describe how the organizations was introduced to the LeSS framework and why it was chosen.
  • Initiating Change: Detail the initial activities and strategies employed at the start of the LeSS adoption.
  • Organizational Structure – Before and After: Contrast the organizational structure prior to and following the LeSS implementation.
  • Role Evolution: Explore how roles within the team or organization changed during the transition.
  • Challenges Faced: Share the problems encountered during the adoption and how they were addressed.
  • Positive Outcomes: Highlight the successes and benefits realized from adopting LeSS.
  • Reflecting on the Journey: Conclude by evaluating whether the LeSS adoption met its objectives and if it was ultimately beneficial.
The Importance of Your Case Study

Crafting a case study is more than just a formality; it serves multiple vital purposes in your journey as a LeSS practitioner:

  • Showcasing Expertise: Your case study is a platform to display your depth of knowledge and hands-on experience in implementing LeSS.
  • Building Credibility: As trainers are linked to their case studies, yours will act as a valuable reference for potential clients, enhancing your professional credibility.
  • Spreading LeSS Awareness: By sharing your case study, you contribute to the global LeSS community, offering insights for learning and aiding in the wider promotion of the LeSS framework.
Valid LeSS(-like) case studies

The case study must be a LeSS adoption or a LeSS-like adoption. LeSS-like adoption are adoptions that have been inspired by the first two LeSS scaling books, but at that time the LeSS rules weren’t explicated. So, the structure isn’t exactly LeSS, but the spirit of the adoption is the same.

We’re likely to look at these factors for LeSS-like adoptions:

  • Not “small”. e.g., 2-3 teams in a localized change is too small, but we will consider each case separately.
    • We expect LeSS trainers to speak out of experience and most 2-team product groups do not give enough experience for training LeSS.
  • Move towards feature teams
  • One Product Owner and One Product Backlog
  • One Sprint
  • PSPI each Sprint, or clearly moving to PSPI (Done each Sprint)
  • Some decent structural change within an organization, and involvement of changes in management.

Cases weaker than the above are likely to be rejected and we’d ask the candidate trainer to first gain a bit more experience. The experience that is expected is a deep involvement with the adoption, not just giving training to the company.

Developing a Personal LeSS Graphical Overview, Mindmap, or Video

One of the creative and insightful steps in your journey is to develop a graphical representation or video that encapsulates your understanding of LeSS. This exercise is crucial for two main reasons:

  • Forming Your Mental Model: By creating this visual or multimedia representation, you solidify your personal comprehension of the LeSS framework.
  • Sharing Your Perspective: It provides us with a window into your interpretation and grasp of LeSS, enriching our understanding of your approach.

Guidelines for Your Creation:

  • Originality is Key: Your submission should be an original piece, distinct from existing LeSS overviews or mindmaps. It should uniquely reflect your interpretation.
  • Comprehensive Coverage: Ensure your creation captures the essence of LeSS, including its frameworks, rules, and guides.
  • Potential for Sharing: Exceptional works may be selected for publication on the website or included in our training materials, benefiting the wider LeSS community.

Explore the candidate trainer graphics currently published on the LeSS site for inspiration and reference.

4. Wrap up with interview and graphics

The graphical overview and the case study will be reviewed. When they are done, you are ready for the last step, the LeSS Trainer Interview.

The In-Depth Knowledge Interview: Assessing Your LeSS Mastery

As a critical step in your journey, you will engage in a comprehensive interview with Bas or Craig. The purpose of this interview is to understand the depth and breadth of your understanding of the LeSS.

Key Areas of Focus:

  • LeSS Rules: Be prepared to discuss in detail the rules that govern the LeSS framework, demonstrating your grasp of their significance and application.
  • LeSS Frameworks: You should be able to elaborate on the various frameworks within LeSS, showcasing your knowledge of their structure and function.
  • LeSS Guides and Experiments: Expect to converse about the different guides and experiments in LeSS, reflecting on their practical implications and how they can be applied in various contexts.

This interview is an opportunity for you to exhibit your comprehensive understanding of LeSS, articulating concepts and practices fluently and spontaneously.

The interview is recommended to be done with the one of us you know least well.

Rules, Frameworks, Guides and Experiments

In the interview, you should expect to able to summarize and expand on all of these.

You will be asked:

  • Summarize LeSS and how the rules follow the principles.
  • For some chapters of the three LeSS books, explain some guides and experiments.
Describe how you plan to do your LeSS Practitioner course

Once being accepted as LeSS trainer, you’re able to do LeSS Practitioner (and Executive) trainings yourself. We (Bas or Craig) would like to hear how you plan to do your course. This could be by sharing the training material, the structure, the concepts or however you like to do it.
