Do you remember the last time you saw a pilot getting ready for a flight? An aircraft cannot take off without a proper runway, as it requires a solid foundation for both takeoff and landing. The runway needs to be well-maintained, and designed for a variety of aircrafts to take off under different conditions.
In agile software development, there is also the need for a “runway” to ensure that features are delivered smoothly and agile growth is possible. In SAFe, the Architectural Runway serves the purpose of allowing development teams to continuously deliver value without jeopardizing the system’s integrity. It acts as a runway in agile development.
Are you wondering how this critical SAFe concept can accelerate your team's delivery capabilities while maintaining technical excellence? In this comprehensive guide, I'll explain what an Architectural Runway is, its essential components, and how successful organizations leverage it to achieve both speed and stability in their development practices.
What is Architectural Runway in SAFe?
The Architectural Runway is the existing code, components, and technical infrastructure that support the implementation of near-term features without excessive redesign and delay. Think of it as the technical foundation that enables teams to build new functionality rapidly and reliably.
Unlike traditional architecture approaches that try to design everything up front. It provides just enough architectural foundation to support current and upcoming features while remaining flexible enough to adapt as requirements evolve.
The Architecture Runway concept emerged from the recognition that agile teams need some level of architectural planning to avoid technical debt and maintain sustainable development velocity. However, this planning must be balanced, providing a sufficient foundation without over-engineering or creating unnecessary constraints.
Essential Components of Architectural Runway
Familiarity with core components like:
Code and Infrastructure
The foundational code base, frameworks, and infrastructure components that provide the basic building blocks for new features. This includes APIs, data models, security frameworks, and integration patterns.
Development and Deployment Pipeline
Automated tools and processes that support continuous delivery and continuous deployment. These enable teams to move code from development to production quickly and safely.
Architectural Standards and Patterns
Documented guidelines, design patterns, and architectural principles that ensure consistency across teams and features. This SAFe architecture guidance helps maintain system coherence as multiple teams contribute to the solution.
Technical Debt Management
Systematic approaches to identifying, prioritizing, and addressing technical debt that could impede future development velocity.
Testing Infrastructure
Automated testing frameworks, test data management, and quality assurance processes that ensure new features don't break existing functionality.
Monitoring and Observability
Tools and practices for monitoring system performance, detecting issues, and gaining insights into system behavior in production environments.
Typical Architectural Runway Development Timeline
The following process is a predictable rhythm aligned with SAFe practices:
1. Program Increment Planning (Foundation Setting)
During PI Planning, architects and teams assess the current runway and identify gaps that need addressing to support upcoming features. This involves collaboration between architects, agile coaches, and development teams.
2. Sprint Planning (Runway Extension)
Each sprint includes specific enabler stories designed to extend or maintain the Architecture Runway. Teams balance feature development with architectural improvements based on immediate and near-term needs.
3. Daily Development (Continuous Assessment)
As teams work on features, they continuously evaluate whether the current runway adequately supports their needs or requires extension through additional enabler work.
4. Sprint Review (Runway Validation)
Teams demonstrate not only completed features but also architectural improvements, ensuring stakeholders understand the technical foundation that enables future capabilities.
5. Inspect and Adapt (Runway Evolution)
Regular assessment of runway effectiveness helps teams identify patterns, adjust approaches, and plan for future architectural needs.
Working Example: Financial Services Platform Architectural Runway
Let me illustrate how a real organization builds and maintains its Architectural Runway:
A financial services company is developing a digital banking platform that must support rapid feature development while maintaining strict security and compliance requirements.
Their Architectural Runway Strategy:
Initial Foundation Building:
The architecture team establishes their core runway with these components:
Infrastructure Layer:

Robust deployment pipelines and testing infrastructure enable teams to release features more frequently and with greater confidence.
Best Practices for Architectural Runway Success
To maximize the effectiveness, consider these proven strategies:
Balance Planning with Flexibility
Provide enough architectural foundation to support known requirements while maintaining flexibility to adapt as new needs emerge. Avoid over-engineering solutions for uncertain future requirements.
Involve the Right Stakeholders
Collaborate with architects, developers, product owners, and agile coaches to ensure technical decisions align with business objectives.
Implement Incremental Architecture
Build incrementally, adding capabilities just before they're needed rather than trying to build everything up front.
Maintain Architectural Visibility
Keep architectural decisions and technical debt visible to all stakeholders through documentation, dashboards, and regular communication.
Automate Everything Possible
Invest in automation for testing, deployment, monitoring, and other routine tasks to free up team capacity for feature development and architectural improvements.
Common Architectural Runway Implementation Challenges
While the benefits are substantial, organizations often encounter obstacles when implementing practices:
Under-Investment in Architecture
Teams may focus exclusively on features while neglecting architectural improvements. Solution: Reserve specific capacity for enabler stories and architectural work in each sprint.
Over-Engineering
Architects may build overly complex solutions for simple problems.
Solution: Follow YAGNI (You Aren't Gonna Need It) principles and build only what's currently needed.
Poor Communication
Architectural decisions may not be effectively communicated to development teams.
Solution: Involve agile coaches in facilitating communication between architects and teams.
Technical Debt Accumulation
Pressure to deliver features quickly can lead to shortcuts that undermine the runway.
Solution: Make technical debt visible and prioritize its resolution alongside feature work.
Lack of Architectural Skills
Teams may lack the skills needed to contribute to development.
Solution: Invest in training and pair experienced architects with development teams.
Architectural Runway Integration with SAFe Practices
The integration is more seamless with other SAFe practices and events:
Epic and Feature Planning
When planning new epics and features, teams assess whether the current runway can support the proposed functionality or needs extension.
Enabler Stories
Much of the runway work is captured as enabler stories that get prioritized alongside user stories in the team and program backlogs.
System Architecture
The runway supports broader system architecture goals by providing the foundation for implementing architectural vision incrementally.
Agile Architecture Practices

Whether you're building a new system from scratch or modernizing an existing platform, investing in a robust runway will accelerate your delivery capabilities and improve your long-term technical sustainability. Consider pursuing SAFe certification to deepen your understanding of these architectural practices and their integration with scaled agile frameworks.
Frequently Asked Questions (FAQs)
1. How much of each sprint should be dedicated to Architectural Runway work versus feature development?
Typically allocate 20-30% of sprint capacity to Architectural Runway activities, including enabler stories and technical debt reduction. New systems might need 40-50% initially to establish foundation, while mature systems may only require 10-15% for maintenance. The key is treating this as an investment - teams that consistently invest in their runway deliver features faster long-term.
2. What's the difference between Architectural Runway and technical debt management?
Technical debt refers to shortcuts that accumulate and slow future development. Architectural Runway is the proactive foundation that prevents technical debt from accumulating. Think of debt as fixing problems after they occur, while runway builds infrastructure to prevent those problems. A well-maintained runway includes systematic debt management as a component.
3. How do you measure the ROI of investing in Architectural Runway?
Track feature delivery velocity, production defect rates, system downtime, and developer productivity. Teams with robust runways typically see 30-50% faster feature delivery and 40-60% fewer production issues. Measure time-to-market for new capabilities and effort required for similar features over time - well-invested runways show decreasing effort as foundation becomes more reusable.
4. Can small teams or startups benefit from Architectural Runway practices?
Yes, but focus on lightweight essentials like automated testing, basic CI/CD pipelines, and simple architectural patterns. Avoid over-engineering while establishing foundational practices that scale with growth. Even startups benefit from automated deployment, basic monitoring, and coding standards. Start small with essential elements and expand as needs grow.
5. How do you convince stakeholders to invest in Architectural Runway when they want customer-facing features?
Demonstrate business impact through concrete examples: "Investing two weeks in deployment pipeline enables daily releases instead of monthly, getting customer feedback 30x faster." Present it as enabling business agility, not technical overhead. Track metrics showing how runway investments accelerate future feature delivery - stakeholders become advocates once they see features delivering in days instead of weeks.
