Agile Engineering: Accelerating Aerospace Innovation for the Future

Agile Engineering is transforming aerospace by enabling rapid prototyping, real-time testing, and faster time-to-market in space and aviation technology.

The aerospace industry, long defined by its meticulous adherence to rigid timelines and waterfall methodologies, is undergoing a seismic shift. As demand for faster innovation, cost efficiency, and adaptability surges, Agile Engineering is emerging as the cornerstone of modern aerospace design and production. This transformative approach—borrowed from software development but reimagined for complex hardware systems—is enabling companies to slash development cycles, mitigate risks, and respond dynamically to evolving technologies and market demands.

The traditional waterfall methodology in aerospace system design follows a structured and sequential process. It starts with comprehensive planning and requirements gathering, which can take significant time before any design or development work begins. This method proceeds through distinct phases, including design, implementation, and testing, with each stage depending on the successful completion of the previous one. While this can provide a clear roadmap for large, complex projects, it also introduces challenges such as inflexibility and delayed feedback. If issues are identified in later stages, such as during testing, they can require extensive rework, increasing costs and project timelines.

Agile Software Development

1. Why Aerospace Needs Agile Engineering

The Limitations of Traditional Methods

For decades, aerospace projects followed linear “design-build-test” workflows, with phases often spanning years. While this approach ensured precision, it struggled to accommodate rapid technological advancements such as artificial intelligence and additive manufacturing. It was also ill-suited to adapt to shifting sustainability mandates, including the push for hydrogen propulsion and carbon-neutral materials. Moreover, unpredictable supply chain disruptions, like those witnessed during the pandemic era, further exposed the inflexibility of traditional methods. A 2022 McKinsey study revealed that 70% of aerospace programs overran budgets under traditional models, while 45% missed deadlines due to late-stage design changes.

Agile to the Rescue

Agile engineering has expanded its influence beyond software development and is increasingly being adopted across all engineering disciplines, including aerospace and defense. Traditional product development methods often focus on sequential processes, but agile emphasizes iterative design and constant feedback, which is proving effective in the complex, high-stakes environment of aerospace and defense. By embracing agile, organizations can foster cross-disciplinary collaboration, combining software, electrical, and mechanical teams into integrated engineering groups. This allows for better coordination and faster problem-solving, especially in systems where different subsystems interact with each other.

Agile principles can also be adapted for hardware development, although modifications are required to address the unique challenges of physical product creation. While making changes to hardware is more costly and testing partial products with customers can be difficult, the rise of digital fabrication tools such as 3D printers, laser cutters, and mills has made iterative hardware development more feasible. These tools enable engineers to quickly produce prototypes that can be tested and refined with customer feedback. This iterative process ensures that designs are aligned with customer needs and that risks are identified and addressed early in the development cycle.

In hardware development, agile methods provide several key benefits, such as continuous feedback, better collaboration across teams, and more rapid iteration of physical prototypes. Each iteration of a prototype can be physically tested, which helps teams identify and solve problems more effectively. This allows for more exploration of possible solutions, reducing the time spent on dead-end designs and increasing the likelihood of successful outcomes. Additionally, continuous testing throughout the process exposes engineering risks early, which helps to avoid costly late-stage design changes. By fostering a culture of learning and adaptation, agile principles are helping aerospace and defense companies innovate more efficiently and create products that better meet customer needs.

Ultimately, the adoption of agile engineering across both software and hardware disciplines in aerospace and defense offers substantial advantages. The iterative nature of agile not only accelerates development but also improves product quality by ensuring that teams can adapt quickly to feedback and changing requirements. As digital tools and technologies continue to evolve, the integration of agile methods in aerospace and defense will likely expand, enabling companies to meet the demands of an increasingly complex and fast-paced industry.

Advantages of Agile in Aerospace

Transitioning to an agile approach allows for a more flexible and responsive development process. Agile engineering breaks down the project into smaller iterations or sprints, each resulting in a potentially shippable product increment. This method fosters continuous collaboration between cross-functional teams and stakeholders, ensuring that the system evolves in alignment with user needs and market demands. Testing is integrated early and frequently, providing real-time feedback that helps identify issues promptly. This allows for quicker adjustments to be made, reducing the risk of costly errors and minimizing delays in meeting project milestones.

Agile’s iterative nature contrasts sharply with the Waterfall methodology’s rigid structure, particularly when it comes to product testing. In a typical waterfall approach, testing occurs only at the end of the development cycle, often leading to delays if problems are found late in the process. However, with agile, testing is part of every sprint, and by the time the final product is completed, significant portions of the system are already tested and operational. This early validation helps to ensure that the product is built to meet user expectations and reduces the likelihood of costly redesigns in later stages.

Moreover, the transition to agile not only accelerates product development but also delivers economic advantages. Although initial costs may be higher due to the need for more frequent iterations and closer collaboration, the long-term savings are significant. Agile projects tend to be more adaptive to change, providing better alignment with evolving market conditions and customer feedback. By allowing teams to fail quickly and learn from prototypes, agile fosters a culture of continuous improvement, leading to more innovative solutions and higher-quality products. Ultimately, this approach enhances the ability to meet user needs effectively and efficiently, offering a competitive edge in aerospace systems design.

Agile in Aerospace Hardware

Agile principles also play a key role in aerospace hardware development, where rapid iteration and constant optimization are vital. The philosophy of agile aerospace development focuses on making incremental improvements to spacecraft designs, rather than attempting to perfect each version at the outset. This approach ensures continuous evolution and refinement of spacecraft architecture, enabling teams to adapt to emerging market demands and technological advancements. Agile product development also accelerates complex aerospace programs by enabling manufacturers to rapidly test, verify, and validate new capabilities in each engineering sprint. This iterative approach ensures that by the end of each sprint, the team can confirm and enhance features that have already been tested virtually, improving the efficiency and effectiveness of the development process.

An example of agile’s impact on aerospace hardware development comes from Latécoère, a French aircraft company that applied agile to revolutionize its aircraft door design process. The company initially aimed to reduce the development time from four years to two years, but with the adoption of agile, they successfully designed and built a new door in just 18 months. This dramatic reduction in timeline highlights how agile methodologies can accelerate product development, allowing companies to meet the fast-paced demands of the aerospace market. Serge Bérenger, Latécoère’s senior vice president of innovation and research & technology, emphasized the importance of trust and empowerment in this agile journey. By refraining from micromanagement and empowering teams to make decisions, the company was able to achieve breakthrough results and deliver products in significantly shorter timeframes.

These examples underscore the transformative potential of agile engineering in aerospace and hardware development. Agile allows organizations to break away from traditional, rigid processes and embrace flexibility, continuous improvement, and rapid response to market changes. Whether applied to spacecraft design, automotive innovation, or aircraft components, agile principles foster collaboration, efficiency, and innovation—ultimately leading to faster and more effective product development.

2. Core Principles of Agile Engineering in Aerospace

Iterative Design Cycles

Instead of freezing designs early in the process, Agile teams rapidly build functional prototypes. Boeing’s T-7A Red Hawk, for example, was developed in just 36 months—compared to the typical 5–8 years—thanks to digital twin-enabled iterations. Similarly, Rocket Lab’s Electron Rocket employs sprint-based workflows to test engine components in parallel, significantly accelerating the pace of upgrades.

Cross-Functional “Swarms”

Agile dismantles the traditional silos between engineers, manufacturers, and clients. NASA’s Artemis Program exemplifies this model, using integrated teams to concurrently design the Orion spacecraft’s hardware and software, which helps resolve conflicts and inefficiencies in real time.

Modular Architectures

Agile Engineering also prioritizes modular systems that allow for incremental upgrades. The F-35’s TR-3 update, for instance, uses open-system avionics, making it possible to integrate new AI-driven capabilities without necessitating a complete jet redesign.

3. Agile in Action: Transforming Aerospace Workflows

Rapid Prototyping & Additive Manufacturing

With the advent of 3D printing, same-day prototype iterations have become a reality. GE Aviation, for example, reduced the part count of its LEAP fuel nozzle from 20 to just one using additive manufacturing, slashing production time by 75%. Similarly, Relativity Space 3D-prints entire rockets within days, enabling rapid design iterations based on real-world test data.

Digital Twins & AI-Driven Simulation

Digital replicas of aircraft or engines allow aerospace firms to conduct extensive virtual testing. Rolls-Royce’s UltraFan engine, for instance, can simulate over 100,000 operational scenarios digitally, vastly reducing the need for expensive and time-consuming physical trials. Airbus’s Wing of Tomorrow project similarly uses AI to predict aerodynamic performance, cutting down on wind tunnel testing by 40%.

Supply Chain Agility

Agile methodologies also foster resilient supplier networks. Lockheed Martin, for instance, shares real-time production data with over 1,500 suppliers via cloud platforms, reducing part delays by 25%. Meanwhile, Joby Aviation collaborates with Toyota to repurpose automotive robotics for use in eVTOL (electric Vertical Takeoff and Landing) manufacturing.

4. Overcoming Aerospace-Specific Challenges

Regulatory Compliance

To align Agile practices with rigorous certification requirements, companies have adopted continuous documentation methods. For instance, the FAA’s SAFRA Framework allows for modular certification of hybrid-electric aircraft systems, facilitating faster compliance. Spirit AeroSystems, meanwhile, uses blockchain technology to track certification data across Agile sprints, ensuring traceability and transparency.

Cultural Shift

Transitioning to Agile demands a fundamental cultural shift within organizations. Leadership buy-in is crucial; Lockheed’s “Skunk Works” division has mandated Agile practices for all classified projects. Upskilling is equally important, as Boeing’s “Digital Hangar” initiative demonstrates by training engineers in AI tools and DevOps practices to stay ahead in an Agile world.

Hybrid Approaches

While the agile approach has proven successful in software and certain engineering projects, its application in mechanical and electrical design remains less common. Agile thrives in environments where adaptability and quick decision-making are essential, but it may be challenging for teams without prior experience or a deep understanding of the methodology. The fast-paced nature of agile can become a risk for teams unfamiliar with the approach, as it requires balancing immediate changes with the ability to defer others for future iterations. In such cases, the agile methodology might struggle to deliver the intended results, especially if the team or client cannot keep up with the rapid pace.

To address these challenges, many organizations are now adopting hybrid methodologies that combine the strengths of both the traditional waterfall approach and agile. The hybrid model allows teams to define clear, initial requirements while remaining adaptable to changing needs through continuous feedback and iterative delivery. By blending the structured tracking and documentation of waterfall with the flexibility and adaptability of agile, hybrid approaches offer a balanced framework that supports both predictability and responsiveness. This methodology enables teams to maintain clarity in project management while still being able to pivot as needed, making it a valuable solution for complex engineering projects.

5. Case Studies: Agile Pioneers

Agile methodologies have proven successful in various aerospace projects, enabling faster, more efficient development processes. One notable example is the Johns Hopkins CubeSat Case, where Agile Systems Engineering concepts were applied in the Multi-Mission Bus Demonstrator (MMBD) project. This initiative involved designing and developing two small satellites at The Johns Hopkins University Applied Physics Lab. By adopting Agile principles, the project was able to iterate quickly, refining the design and addressing challenges in a responsive and flexible manner. This approach enabled the team to meet complex requirements within a constrained timeline, ultimately contributing to the success of the project.

One notable example of successful agile implementation in aerospace is the Munich Orbital Verification Experiment II (MOVE-II) project at the Technical University of Munich. The project applied agile software development to create the onboard computer software for a student satellite in just a few months. The process involved breaking down the satellite’s software into subsystems (e.g., thermal, communications, and power systems), with each component being developed iteratively. This approach enabled clear definition of interfaces between subsystems and allowed independent development of software components, which were then integrated into the satellite. By the end of the project, a minimum viable product (MVP) had been established, which could be tested and refined over time, allowing for continuous improvement and flexibility in responding to issues.

Companies like Airbus and Boom Supersonic have demonstrated that by adopting Agile methods, development timelines can be reduced by 30–50%, proving the viability of Agile even for billion-dollar projects.

Planet Labs

Planet Labs is revolutionizing space-based Earth observation by deploying large constellations of small, cost-effective satellites. Each of their nanosatellites, known as “Doves,” follows a 3U form factor (10cm x 10cm x 30cm) and is equipped with an optical system capable of capturing imagery with a Ground Sample Distance (GSD) of 3-5 meters. The company’s approach is based on frequent updates and replacements, with each satellite designed for an operational lifespan of around three years. This model enables rapid advancements and ensures that the constellation continuously provides high-quality, up-to-date imagery of the Earth’s surface.

The company’s success is attributed to its “agile aerospace” approach, which emphasizes rapid iteration and frequent testing in space. Since 2012, Planet Labs has completed 14 major iterations of its Dove spacecraft, incorporating lessons learned from each cycle. This iterative process allows them to release new spacecraft designs regularly and refine them based on real-world performance. Planet Labs has also developed its own optical systems in successive versions (Planet Scope 0, 1, and 2) to further enhance the capabilities of its satellites. By maintaining a constant monitoring mode, the satellites capture imagery of the sunlit portions of the Earth’s surface, continuously feeding data to the ground stations for analysis and use.

One of the key advantages of Planet Labs’ agile approach is the ability to quickly launch satellites, even if they are not yet perfect. This initial rapid deployment helped the company navigate regulatory challenges, integrate its launch processes, and develop constellation management software. Importantly, early satellite launches provided valuable feedback from customers based on actual imagery, which guided engineering improvements in subsequent iterations. This hands-on testing approach contrasts with the more analytical methods commonly used in traditional aerospace, enabling Planet Labs to innovate faster and adapt to customer needs in real-time.

However, the agile aerospace model is not without its challenges. The small size and low cost of Planet Labs’ satellites mean they do not have the redundancy built into larger, more expensive satellites. If a critical component fails, the satellite may need to be retired, potentially reducing reliability. Additionally, the use of commercial-off-the-shelf (COTS) components—while cost-effective—can result in lower reliability compared to aerospace-grade components. Despite these limitations, Planet Labs mitigates risk by operating a large constellation of satellites. This redundancy ensures that if one satellite fails, others can cover the gap, maintaining continuous imagery coverage.

Planet Labs’ focus on miniaturization, rapid iteration, and agile development has allowed the company to maintain a competitive edge in the rapidly evolving field of Earth observation. With around 100 satellites in orbit, Planet Labs continuously replaces outdated models with newer, more advanced versions. Their constellation management software plays a critical role in ensuring smooth operations, detecting problems, and repositioning satellites to maintain seamless coverage. This approach has resulted in a reliable, cost-effective solution for Earth observation that meets the needs of a growing global market.

Beta Technologies showcased the flexibility of Agile by pivoting from a cargo model to a passenger-focused model within only six months, relying heavily on customer feedback gathered during FAA trials.

Northrop Grumman’s B-21 Raider

Agile teams at Northrop Grumman worked to integrate stealth coatings and propulsion systems in parallel rather than sequentially, keeping the B-21 Raider sixth-generation bomber on schedule and within budget.

6. The Future of Agile Aerospace

AI-Powered Iterations

Generative AI tools like Dassault’s CATIA GPT will soon automate design optimizations, enabling engineers to predict and balance trade-offs related to weight, stress, and cost in real time.

Hybrid Agile-Waterfall Models

Future aerospace programs such as the Next-Gen Air Dominance (NGAD) fighter initiative are expected to combine Agile methods for subsystem development with traditional waterfall approaches for full-platform integration, creating a best-of-both-worlds model.

Workforce Revolution

According to a 2023 Deloitte report, 60% of aerospace engineers will need Agile and DevOps skills by 2030, underscoring the urgent need for workforce transformation to support Agile initiatives.

Conclusion: Agile or Obsolete

The aerospace industry’s future belongs to those who embrace Agile Engineering. Organizations adopting Agile workflows are already achieving 50% faster time-to-market, 20–30% cost savings, and unmatched adaptability in the face of disruption. As sustainability pressures mount and global competition intensifies, Agile isn’t just an option—it’s the key to survival and dominance in 21st-century aerospace
