Before we delve into the intricacies of CSM and PSM certifications, let us first understand what Scrum is. Agile software development has revolutionised the way businesses approach problem-solving and project management. One of the most popular methodologies in this approach is Scrum, which prioritises efficiency, flexibility, and transparency. With its iterative and incremental structure, Scrum enables self-organising teams to continuously improve and adapt to changing requirements and market conditions. This allows businesses to deliver high-value solutions quickly and effectively, ensuring that their strategies and goals remain on track. Ultimately, the flexibility and responsiveness offered by Scrum make it an essential tool for businesses operating in a rapidly changing environment.


From the Scrum Guide:


“Scrum is a framework for developing, delivering, and sustaining complex products. Scrum is not a process, technique, or definitive method. Rather, it is a framework within which you can employ various processes and techniques. Scrum makes clear the relative efficacy of your product management and work techniques so that you can continuously improve the product, the team, and the working environment.


The latest update to the Scrum Guide also lists possible uses for Scrum:

  • Research and identify viable markets, technologies, and product capabilities;
  • Develop products and enhancements;
  • Release products and enhancements, as frequently as many times per day;
  • Develop and sustain Cloud (online, secure, on-demand) and other operational environments for product use; and,
  • Sustain and renew products.


Origin of Scrum

Scrum is a process framework that has been used to manage work on complex products since the early 1990s. Ken Schwaber and Jeff Sutherland worked on Scrum until 1995, when they co-presented Scrum at the OOPSLA Conference 1995. In 2001, the Scrum Alliance was founded and the Certified Scrum Master (CSM) certification program was launched. This presentation marked the first formal definition of Scrum and documented the learnings gained by Ken and Jeff over the previous few years.


Scrum has been sustained and evolved for over 20 years by both Schwaber and Sutherland. In fact, both were present at the writing of the Agile Manifesto in 2001, where Scrum was one of several lightweight processes presented. Today, the Scrum Alliance promotes the use of Scrum and provides training and resources to help teams adopt this valuable framework.


Scrum Alliance vs

In 2001, Ken Schwaber made a bold move: he left behind the Scrum Alliance, an organisation he co-founded, and instead founded His reasons for doing so stemmed from a deep concern about the state of Scrum methodology implementation in organisations. Specifically, there was a problematic perception that pervaded the industry–that the two-day Scrum Alliance CSM® certification course was enough to properly certify someone as a Scrum Master.


While the CSM®️ certification is one of the most popular choices,’s PSM™ certification stands apart with its unique approach. Unlike the CSM®️ certification, attending a workshop is not mandatory for PSM™ certification. However, that doesn’t mean the certification is any easier. The PSM™ assessments are designed to test a candidate’s knowledge and understanding of Scrum, making it a more rigorous process. But with that comes the assurance of attaining a precise and well-rounded understanding of one of the most influential project management methodologies in the industry.


Choosing Between the Best Scrum Master Certifications: CSM and PSM


When it comes to pursuing a Scrum Master certification, two names stand out prominently in the industry: Certified ScrumMaster (CSM®️) and Professional Scrum Master (PSM™). These certifications are highly regarded by organisations worldwide and hold the potential to significantly elevate a professional’s career in agile project management.


CSM®️ (Certified ScrumMaster):


CSM®️, offered by Scrum Alliance, is one of the most widely recognized Scrum Master certifications. The CSM®️ certification focuses on the fundamental principles of Scrum, emphasizing the role of the Scrum Master in facilitating team collaboration and removing impediments.

On the other hand, PSM™, offered by, emphases a deep understanding of Scrum principles and the ability to apply them effectively in real-world scenarios. PSM™ certifications are available at three different levels: PSM™ I, PSM™ II, and PSM™ III, each assessing a candidate’s knowledge and practical skills at varying levels of complexity. PSM™ certifications require candidates to pass a rigorous online assessment, demonstrating their comprehensive grasp of Scrum concepts and its applications.

CSM®️ is an excellent starting point for those new to Scrum and seeking a foundational understanding of its principles.
