Agile development is all about delivering value quickly while maintaining the ability to adapt. But when working at scale, agility often collides with technical complexity. One powerful concept that helps teams stay nimble while preparing for future work is the Architectural Runway.

In this post, we’ll explore how the architectural runway works in SAFe (Scaled Agile Framework), why it’s essential for sustainable delivery, and how it allows teams to build for the future without sacrificing speed.

What Is the Architectural Runway?

The architectural runway refers to the existing code, components, and technical infrastructure needed to support the implementation of near-term features. Think of it as the technical foundation that lets Agile Release Trains (ARTs) deliver business value without being blocked by architecture-related constraints.

It’s not about creating a full-blown, detailed architecture upfront. Instead, it’s about ensuring just enough of the necessary technical scaffolding is in place so features can flow smoothly through the system.

This aligns directly with SAFe’s emphasis on continuous value delivery and lean thinking.

Why Architectural Runway Matters

Without an architectural runway, teams may find themselves unable to implement new features due to missing infrastructure or unresolved technical challenges. They’re left playing catch-up, which leads to rework, delayed releases, and frustrated stakeholders.

A healthy architectural runway:

• Reduces delivery delays by anticipating future needs

• Supports agility by allowing for modular and incremental design

• Minimizes rework by aligning architecture with the evolving solution

• Improves flow efficiency by removing technical blockers

This is especially relevant for teams working in large solution contexts or building complex, long-lived systems.

Who Builds the Architectural Runway?

The primary responsibility lies with the System and Solution Architects. They work closely with Agile teams to incrementally evolve the system architecture.

However, it’s not a one-way directive. Teams, particularly those with SAFe Certified Scrum Masters and SAFe Product Owners/Product Managers, contribute to evolving the architecture through feedback, discovery spikes, and enabler stories.

The runway is extended through enabler epics, capabilities, and stories—work items focused on exploration, prototyping, or creating new components.

Balancing Feature Delivery and Technical Readiness

A common misconception is that architecture and delivery are at odds. But SAFe promotes an integrated approach: planning for architectural runway happens within the same cadence and structure as feature delivery.

During PI Planning, architectural needs are discussed, prioritized, and added to the backlog. These enablers don’t compete with features—they enable them. And it’s the job of the RTEs (Release Train Engineers) and Product Management to balance both types of work across the train.

Techniques to Maintain a Healthy Architectural Runway

Here’s how organizations can ensure their runway is ready—without over-engineering or slowing down delivery:

1. Adopt the Principle of Intentional Architecture

SAFe promotes Intentional Architecture—a lightweight, collaboratively built plan that guides decisions. This avoids the extremes of rigid up-front design or complete architectural anarchy.

2. Use Enablers as First-Class Backlog Items

Architectural work isn’t done “on the side.” It’s represented in the same Agile backlog as features. Enabler stories are estimated, prioritized, and demoed like any other story.

3. Implement Continuous Exploration and Learning

Architects should regularly explore new technologies, standards, and patterns. Practices like spikes and hackathons help teams validate ideas early—before building them into the system.

4. Synchronize Architecture with PI Cadence

The architectural vision should evolve in lockstep with the Program Increment. This supports iterative development while ensuring that long-term capabilities are not neglected.

Architectural Runway in Action: A Practical Example

Let’s say a financial services enterprise is planning to support real-time payments across multiple platforms. The business team defines features like mobile wallet support and instant settlements.

However, delivering these features requires:

• A scalable messaging backbone

• Real-time fraud detection capability

• Updated APIs to interface with payment gateways

If these architectural components are not prepared in advance, feature development will stall. But by using enabler stories to build the messaging backbone and fraud detection engine during the current PI, the teams are ready to implement the customer-facing features in the next PI—without delay.

This proactive approach is the essence of the architectural runway.

Role of SAFe Architects

SAFe defines three architect roles: Enterprise, Solution, and System Architect. Each plays a distinct part in extending the runway:

• System Architects focus on team-level architecture

• Solution Architects ensure alignment across ARTs

• Enterprise Architects connect architecture with business strategy

These roles guide and support the runway with a focus on Lean-Agile principles and collaboration, rather than top-down mandates.

The importance of Agile architecture is embedded in the mindset taught during Leading SAFe training, which helps leaders support technical agility.

Avoiding Common Pitfalls

While the architectural runway enables speed and flexibility, there are traps to avoid:

• Overbuilding runway: Trying to solve all future problems upfront goes against lean thinking. Build just enough.

• Neglecting runway work: Pushing only features leads to accumulating technical debt.

• Siloed architecture decisions: Keep architecture collaborative and visible through tools like architecture Kanban and design reviews.

For those facilitating architectural synchronization across Scrum teams, the SAFe Advanced Scrum Master Certification is a helpful resource.

Conclusion

The architectural runway is a quiet enabler of speed. It ensures that when teams are ready to build and release value, the ground beneath them is stable—and the path ahead is clear. Balancing architectural readiness with lean delivery is not just possible; it’s essential for sustained agility.

By integrating architectural planning into PI cadence, using enabler stories, and keeping design collaborative, organizations can avoid bottlenecks while scaling smoothly.

To lead Agile teams that understand both business value and technical readiness, start with certifications like Leading SAFe or deepen your delivery capabilities with the SAFe Scrum Master Certification.
