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


Agile, which includes Agile testing, distinguishes apart from other software development approaches due to its iterative approach to development, expedited testing and delivery, and cooperation amongst cross-functional teams. It helps businesses to have a larger hunger for change and facilitates the production of goods of a higher quality. Agile makes it possible to rapidly create high-quality software solutions that are aligned to both the objectives of the company and the goals of its customers. This is made possible by promoting cooperation, responsibility, and self-organization. It should come as no surprise that corporate firms have adopted Agile in order to kickstart digital transformation.

Scrum is a management tool that is included with Agile that may be used by businesses to oversee the creation of high-quality software solutions. Scrum is a framework for project management that is both a subset of Agile and a subset of Agile itself. Scrum lets diverse teams work together by breaking down barriers, and it helps teams constantly develop by providing better learning experiences. It facilitates the building, testing, delivering, and maintenance of complex software systems by teams. The proper administration of a project may be facilitated by using scrum, which includes holding regular meetings of the team, selecting and carrying out duties, and making use of various tools.

They are controllable and provide the outputs that are wanted up to the point where approaches like as Agile and Scrum are implemented at the level of a single team. On the other hand, difficulties come to the fore as the size of the projects and the teams involved both increase. In situations like this, new Agile methodologies, such as embracing an Agile testing approach, are required to grow, and some examples of such methodologies are SAFe, SoS, and LeSS.

Explain the SAFe, SoS, and LeSS acronyms.

SAFe, which stands for Scaled Agile Framework, is now the most widely used framework in the world for expanding Agile practices across a business. Through the use of time-tested concepts, regulations, and procedures, it enables enterprises to consistently offer value while adhering to a predetermined timetable. SAFe encourages communication across Agile teams, as well as alignment and the delivery of goods. It establishes a culture that the management and any other stakeholders in the business should work to successfully pursue in order to achieve the firm’s objectives. The principles of alignment, transparency, built-in quality, and program execution are at the center of the SAFe framework. It encourages improved decision making across organizational and functional boundaries that is based on lean principles.

The Scrum of Scrums, often known as SoS, is the agile scaling framework that has been around the longest. Its purpose is to connect the efforts of several scrum teams who are all working on the same project. It makes communication between teams easier, making it more likely that the results of the work done by one team will be in sync with the results of the work done by other teams, even if there is some overlap in the order in which events take place. The real process of coordinating across teams takes place at a meeting at which a scrum master is appointed to represent each of the participating teams. In the event that the topic being discussed is very technical, the scrum master, as well as a member of the team who is technically competent, may choose to attend the meeting. The purpose of Scrum of Scrums is to guarantee that all of the different teams will achieve their sprint objectives in a manner that is congruent with the overarching objective of the enterprise.

Large Scale Scrum, often known as LeSS, is a framework that allows several teams to collaborate on a single project. It starts with the creation of a single scrum team and is then progressively implemented across numerous teams that are working on the same project. The LeSS framework makes it possible to apply the scrum-based ideas and aspirations to a big organization by making use of previously established standards. LeSS focuses on developing responsible teams that work together more effectively and have a sharper attention to the needs of their customers. It highlights qualities like as learning, transparency, and supplying customer-centric values as essential for businesses to maintain their responsiveness, agility, and competitiveness.

What’s the difference between SAFe, SoS, and LeSS?

The following list of parameters may be used to describe the differences that can be found between the three different frameworks:

Methodology utilized: LeSS and SoS are exclusively based on the scrum methodology and apply its concepts, practices, and responsibilities to a significant number of teams working on a single project. Therefore, it is not necessary for the teams who are currently using scrum to go through the process of restructuring in order to adopt these two frameworks.

Nevertheless, SAFe is founded on Agile in its whole and modifies its ideals to fit the needs of a huge organization. It gives many teams within a company the opportunity to choose their own methodologies, such as an agile testing framework to scale, such as Scrum or Kanban, amongst others. It requires more effort during implementation, but it allows teams more choice in selecting the frameworks they want to use.

Size of the company: Using SoS to coordinate work is a better choice for firms that have a smaller number of scrum teams since it guarantees that everyone is on the same page. When it comes to scaling Agile for big organizations, LeSS and SAFe are the frameworks of choice.

Structure of the company: SoS enables improved inter-team collaboration and the definition of the team structure, but it does not give coverage to the whole of the portfolio levels. Because of this, it is possible to handle daily operations on a smaller scale with ease, but it is impossible to realize the long-term objective in this manner. The addition of LeSS does increase the portfolio levels, and it also makes it easier to comprehend how the organization is structured. However, SAFe makes it possible to establish a whole set of standards for the structure of the firm, and it also creates an atmosphere in which Agile may be implemented.

Cost: Both SoS and LeSS have lower costs since they are developed from the scrum, which requires very little training and very little reorganization of teams. In this stage, teams have the necessary knowledge but must add many new components to their normal procedures. On the other side, adopting SAFe necessitates a reorganization of the company and results in increased expenses.


SAFe, SoS, and LeSS are three frameworks that offer scalability solutions for digital transformation in big companies, medium-sized businesses, and small businesses, respectively. These solutions are available regardless of the method for Agile testing an individual chooses to use. Therefore, it is essential for businesses to comprehend their requirements and choose the one Agile testing framework that is efficient, both for the here and now and for the foreseeable future.
