It all starts with a Lean-Agile Mindset.
The Lean-Agile Mindset is the combination of beliefs, assumptions, and actions of SAFe leaders and practitioners who embrace the concepts of the Agile Manifesto and Lean thinking. It’s the personal, intellectual, and leadership foundation for adopting and applying SAFe principles and practices.
SAFe is based on three bodies of knowledge: Agile development, systems thinking, and Lean product development .
Agile provides the tools needed to empower and engage teams to achieve unprecedented levels of productivity, quality, and engagement. But a broader and deeper Lean-Agile mindset is needed to support Lean and Agile development at scale across the entire enterprise. Therefore, there are two primary aspects of a Lean-Agile mindset:
- Thinking Lean – Much of Lean thinking is represented by the SAFe House of Lean (Figure 1). The roof represents the goal of delivering value. The pillars embody respect for people and culture, flow, innovation, and relentless improvement to support the goal. Lean leadership provides the foundation on which everything stands.
- Embracing agility – SAFe is built entirely on the skills, aptitude, and capabilities of Agile teams and their leaders. The Agile Manifesto provides a value system and set of principles that are fundamental to the mindset for successful Agile development.
Understanding and applying this knowledge helps create the Lean-Agile mindset, part of a new management approach and an enhanced company culture. It provides the leadership needed to drive a successful SAFe transformation, helping individuals and businesses achieve their goals.
The SAFe House of Lean
Initially derived from Lean manufacturing, the principles and practices of Lean thinking as applied to software, product, and systems development are now deep and extensive . For example, Ward , Reinertsen , Poppendieck,, Leffingwell , and others have described aspects of Lean thinking, placing many of the core principles and practices in a product development context. Along with these, we present the SAFe House of Lean, as illustrated in Figure 1, inspired by houses of Lean from Toyota and others.
The Goal – Value
The goal of Lean is to deliver the maximum customer value in the shortest sustainable lead time, while providing the highest possible quality to Customers and society as a whole. High morale, safety, and customer delight are additional goals and benefits.
Pillar 1 – Respect for People and Culture
A Lean-Agile approach doesn’t implement itself or perform any real work. People do all the work. Respect for people and culture is a basic human need. People are empowered to evolve their own practices and improvements. Management challenges people to change and may steer them toward improvement. However, it’s the teams and individuals who learn problem-solving and reflection skills, and are accountable for making the appropriate improvements .
The driving force behind this behavior is culture. To cultivate a truly Lean organization, the culture will need to change. For that to happen, the organization and its leaders must change first. The principle of respect for people and culture should also extend to relationships with Suppliers, partners, customers, and the broader community that supports the Enterprise.
Where there is urgency for positive change, improvements in culture can be achieved gradually. First, understand and implement SAFe values and principles. Second, deliver winning results. Lastly, changes to culture will follow naturally.
Pillar 2 – Flow
The key to successfully executing SAFe is to establish a continuous flow of work that supports incremental value delivery, based on continuous feedback and adjustment. Continuous flow enables faster value delivery, effective Built-in Quality practices, constant improvement, and evidence-based governance.
The principles of flow are an important part of the Lean-Agile mindset. These include understanding the full Value Stream, visualizing and limiting Work in Process (WIP), and reducing batch sizes and managing queue lengths. Additionally, Lean focuses on identifying and constantly reducing delay and waste (non-value-added activities).
Lean-Agile principles provide a better understanding of the system development process, incorporating new thinking, tools, and techniques that leaders and teams can use to move from phase-gated processes to DevOps and a Continuous Delivery Pipeline that extends flow to the entire value delivery process.
Pillar 3 – Innovation
Flow builds a solid foundation for value delivery. But without innovation, both product and process will steadily decline. To support this critical part of the SAFe House of Lean, Lean-Agile Leaders:
- Get out of the office and into the actual workplace where value is produced and products are created and used (known as gemba). As Taiichi Ohno put it, “No useful improvement was ever invented at a desk.”
- Provide time and space for people to be creative. Time for innovation must be purposeful. Innovations can rarely occur in the presence of 100 percent utilization and continuous firefighting. SAFe’s Innovation and Planning Iteration is one such opportunity.
- Apply Continuous Exploration, the process of constantly exploring market and user needs—and defining a Vision, Roadmap, and set of Features that address those needs.
- Apply innovation accounting . Establish nonfinancial, non-vanity Metrics that provide fast feedback on the important elements of the new innovation.
- Validate the innovation with customers, then pivot without mercy or guilt when the hypothesis needs to change.
Pillar 4 – Relentless Improvement
The fourth pillar is relentless improvement. This encourages the organization to become a learning enterprise through continuous reflection and persistent progress. A constant sense of competitive danger drives the company to aggressively pursue improvement opportunities. Leaders and teams do the following:
- Optimize the whole, not the parts, of both the organization and the development process
- Consider facts carefully, then act quickly
- Apply Lean tools and techniques to determine the root cause of inefficiencies and apply effective countermeasures quickly
- Reflect at key milestones to openly identify and address the shortcomings of the process at all levels
Foundation – Leadership
The foundation of Lean is leadership, the key enabler for team success. The ultimate responsibility for the successful adoption of the Lean-Agile approach lies with the enterprise’s managers, leaders, and executives. According to Deming, “Such a responsibility cannot be delegated” to Lean-Agile champions, working groups, a Program Management Office (PMO), process teams, outside consultants, or any other party . To achieve success, leaders must be trained in these new and innovative ways of thinking and exhibit the principles and behaviors of Lean-Agile leadership.
Lean thinking deviates from common experience with Agile, which was often introduced as a team-based process that tended to exclude management. Unfortunately, that doesn’t scale. Here is a key differentiator between traditional Agile and one of the key drivers for SAFe:
In traditional Agile, the expectation has been that management simply supports the teams and helps eliminate impediments as they arise. In Lean-Agile development, however, the expectation is that management actually leads the teams. It embraces the values of Lean, is competent in the basic practices, proactively eliminates impediments, and takes an active role in driving organizational change and facilitating relentless improvement.
The Agile Manifesto
In the 1990s, responding to the many challenges of waterfall processes, a number of lighter-weight and more iterative development methods arose. In 2001, many of the leaders of these methods came together in Snowbird, Utah. While there were differences of opinion on the specific merits of one method over another, the attendees agreed that their common values and beliefs dwarfed the differences. The result was a Manifesto for Agile Software Development, a turning point that clarified the new approach and started to bring the benefits of these innovative methods to the whole development industry . The Manifesto consists of the value statement shown in Figure 2, and a set of principles shown in Figure 3.
Along with the various Agile methods, the Agile Manifesto provides the foundation for effective, empowered, self-organizing teams. SAFe extends this foundation to the level of teams of teams, applying Lean thinking to understand and relentlessly improve the systems that support their critical work.
