What Is the Difference Between SAFe, SoS, and LeSS?

Among the various approaches to software development, Agile, including Agile testing, emerges in its own style of development, rapid testing and delivery, and collaboration between different working groups. It allows for the creation of high-quality products and empowers businesses to have a strong desire for change. Difference Between SAFe SoS and LeSS

By promoting collaboration, accountability, and self-organization, Agile facilitates the rapid delivery of state-of-the-art software solutions tailored to customer needs and organizational goals. Not surprisingly, business owners have embraced Agile to set up digital transformation.

With Agile comes the scrum, which organizations can use to manage the development of high-quality software solutions.

As an Agile clip and project management framework, scrum helps to divide teams into working collaboratively by breaking down silos. And continuously improving with a better learning experience.

Allows teams to build, test, deploy, and maintain complex software solutions. Combining group meetings, selecting and performing roles, and the use of tools, the scrum facilitates successful project management.

Until methods like Agile and Scrum are used at the same group level, they are manageable and produce the results you want. However, challenges arise as teams and the level of projects grow exponentially. In those cases, new Agile methods that include taking the Agile test method are to measure – SAFe, SoS, or LeSS.

What is SAFe, SoS, and LeSS?


Known as the Scaled Agile Framework, SAFe becomes the world’s leading Agile measurement framework. It helps organizations to deliver value continuously and within a predictable schedule through proven policies, rules, and practices.

SAFe promotes collaboration, coordination, and delivery of products across all Agile groups. It defines a culture, which management and other stakeholders must successfully follow to achieve the goals of the organization.

SAFe’s core values ​​are alignment, transparency, built-in quality, and system performance. It promotes decision-making based on greater limitations of organizational and operational limits.


Scrum of Scrums happens to be the oldest rating framework to integrate the work of multiple scrum teams working on a single project.

It facilitates communication between the parties to ensure that the result of each group’s delivery is consistent with the results of the other groups. Even if there is a sequence of events. Real coordination between the teams is done at a meeting where each team is represented by the chosen scrum chief.

In the event that the discussion is technologically good, then the scrum manager. And legally qualified team members may attend the meeting.

The purpose of Scrum of Scrums is to ensure that individual parties meet their sprint goals in line with the objective of the organization as a whole.


Large Scale Scale is a multi-team framework that works on a single project. It starts with forming a single scrum team and is gradually applied to multiple teams working on the same project.

The LeSS framework allows for the application of scrum-based policies and opinions in large businesses using proven rules. LeSS works to build responsible teams with greater collaboration between them and better customer focus.

It emphasizes qualities such as reading, transparency, and providing customer-focused values ​​to organizations. So that they are always responsive, fast, and competitive.

SAFe, SoS, and LeSS – differences

The differences between the three categories can be explained by the following parameters:

Method used:

LeSS and SoS are based solely on the scrum base and apply their own methods, practices, and roles to a large number of teams working on a single project.

Therefore, groups already working on scrum find it easier to use these two frameworks without rearrangement.

However, SAFe is based on Agile as a whole and aligns its values ​​with the larger business. It allows multiple teams in the organization to choose their own methods as the agile testing framework – Scrum, Kanban, and others.

It puts a lot of effort into implementation but gives groups the freedom to choose their own structures.

Company size:

For companies with a small number of scrum teams, SoS is the best way to coordinate work as it ensures everyone is on the same page. So LeSS and SAFe are good frameworks for measuring the Agile of a large organization.

Company Structure:

SoS allows for better team collaboration and defining team structure but does not provide coverage at all portfolio levels. This makes it easier to manage day-to-day operations on a small scale but fails when it comes to achieving long-term vision.

LeSS adds to portfolio levels and helps better understand corporate structure. However, SAFe allows for a complete set of rules outlined in company building and creates an environment that will be Agile-friendly.


Both SoS and LeSS are less expensive as found in a scrum and require less training or team reconstruction. Here, groups should add a few layers to their daily routines. On the other hand, SAFe requires organizational restructuring and is very expensive.

The conclusion

In addition to the one Agile testing approach being implemented. The three SAFe, SoS, and LeSS frameworks provide digital transformation failure solutions for large, medium, and small businesses, respectively.

Therefore, it is important for organizations to understand their needs and to choose a single Agile testing framework that works, both now and in the future.
