What are the pros and cons of using SAFe vs Scrum @ Scale (S@S) as your enterprise framework?
Sort by:
There are many factors that are to be taken care in mind while making a choice between SAFe and S@S for an enterprise. The organisation size, teams/projects , avg. team size and adoption scale are few of these factors. While SAFe and S@S are there to ensure structure, predictability and disciplines across deliveries, bring agility and continuous integrations of different teams. There applicability in one env will be not be same as different env. Like S@S may work for orgs with small team sizes and fresh adoptions but it will not be suited for very large orgs with thousands of teams and projects. Also, migration from already adopted SAFe setups to S@S will cause disruptions as well. While SAFe has proven its value with widespread adoptions across industries , S@S is early in the evolution and adoption game.
Both frameworks have pluses ands minuses. The real question is which framework is best suited for your organization. If some team members already know one or the other, the best option may be to go with it and expand it, as retraining is usually costly in time and money.
The basic structure of SAFe is the Agile Release Train (ART). It is considered as a team of Agile teams that takes care of the processes, development, and delivery, together with all other project stakeholders.
When compared to Scrum at Scale, the SAFe framework may not be as customizable. This means that SAFe has a more complex structure and adds more processes, layers, functions and tools to the project’s value delivery.
By comparison, the modular approach of Scrum at Scale helps to properly scale the Agile culture, enabling the alignment of the entire organization to share the same goals in the project and the process.
The main difference is that Scrum aims to improve performance in small teams by simplifying processes and packaging change management in small predictable iterations, while SAFe is aiming to drive agile practices across the whole organization.
Keeping this in mind, the downsides are quite straightforward:
- Scrum will underperform for large organizations.
- SAFe will bring a lot of redundancy for a small team.
SAFe is a framework that needs to be applied at an entire organizational level. It starts with the strategy and how to create portfolios and journeys to fulfill that strategy. Then it whittles down to how to set up teams, select projects, and measure your programs' success. It is not just a method of scaling your Agile software teams. Unfortunately, people jump into implementing SAFe without thinking through how they would use the framework to transform their organization. This also means it is very complex and can be daunting. However, there are mechanisms to implement it though it requires long vision.
S@S, on the other hand, is more bottoms-up approach (you have teams and they need to learn to work together) that can be applied without trying to do an organizational transformation across all functions. It is intentionally left open so that practitioners can expand and plug to other things.
There is no one-size-fits-all answer to this question, as the best enterprise framework for a given organization depends on the specific needs and goals of that organization. However, some general pros and cons of SAFe and Scrum @ Scale (S@S) as enterprise frameworks can be outlined as follows:
SAFe Pros:
- SAFe is a tried-and-tested framework that has been used by many organizations with success.
- SAFe is a comprehensive framework that covers all aspects of enterprise software development, from product planning and delivery to portfolio management.
- SAFe includes built-in support for scaling Agile practices to the enterprise level.
SAFe Cons:
- SAFe can be complex and difficult to implement, particularly for organizations new to Agile.
- SAFe requires a high level of commitment from senior management in order to be successful.
- SAFe can be inflexible, and may not be the best fit for organizations with very specific needs.
Scrum @ Scale (S@S) Pros:
- S@S is a simpler and more lightweight framework than SAFe, and is therefore easier to implement.
- S@S is more flexible than SAFe, and can be customized to better fit the needs of specific organizations.
- S@S includes built-in support for scaling Agile practices to the enterprise level.
Scrum @ Scale (S@S) Cons:
- S@S is a newer framework than SAFe, and has not been used as widely or for as long.
- S@S is not as comprehensive as SAFe, and does not cover all aspects of enterprise software development.
- S@S may not be the best fit for organizations with very complex needs.
