[DevoxxBE2025] Your Code Base as a Crime Scene
Lecturer
Scott Sosna is a seasoned technologist with diverse roles in software architecture and backend development. Currently an individual contributor at a SaaS firm, he mentors emerging engineers and authors on code quality and organizational dynamics.
Abstract
This discourse analogizes codebases to crime scenes, identifying organizational triggers for quality degradation such as misaligned incentives, political maneuvers, and procedural lapses. Contextualized within career progression, it analyzes methodologies for self-protection, ally cultivation, and continuous improvement. Through anecdotal examinations of common pitfalls, the narrative evaluates implications for maintainability, team morale, and professional resilience, advocating proactive strategies in dysfunctional environments.
Organizational Triggers and Code Degradation
Codebases often devolve due to systemic issues rather than individual failings, akin to unsolved mysteries where clues point to broader culprits. Sales commitments override engineering feasibility, imposing unrealistic timelines that foster shortcuts. In one anecdote, promised features without consultation led to hastily patched legacy systems, birthing unmaintainable hybrids.
Politics exacerbate this: non-technical leaders dictate architectures, as when a director mandated a shift to NoSQL sans rationale, yielding mismatched solutions. Procedural gaps, like absent reviews, allow unchecked merges, propagating errors. Contextualized, these stem from misaligned incentives—sales bonuses prioritize deals over sustainability, while engineers bear long-term burdens.
Implications include accrued technical debt, manifesting as fragile systems prone to outages. Analysis reveals patterns: unchecked merges correlate with higher defect rates, underscoring review necessities.
Interpersonal Dynamics and Blame Cultures
Blame cultures stifle innovation, where finger-pointing overshadows resolution. Anecdotes illustrate managers evading accountability, redirecting faults to teams. This erodes trust, prompting defensive coding over optimal solutions.
Methodologically, fostering psychological safety counters this: encouraging open post-mortems focuses on processes, not persons. In dysfunctional settings, documentation becomes armor—recording decisions shields against retroactive critiques.
Implications affect morale: persistent blame accelerates burnout, increasing turnover. Analysis suggests ally networks mitigate this, amplifying voices in adversarial environments.
Strategies for Professional Resilience
Resilience demands proactive measures: continual self-improvement via external learning equips engineers for advocacy. Cultivating allies—trusted colleagues who endorse approaches—extends influence, socializing best practices.
Experience tempers reactions: seasoned professionals discern battles, conserving energy for impactful changes. Exit strategies, whether role shifts or departures, preserve well-being when reforms falter.
Implications foster longevity: adaptive engineers thrive, contributing sustainably. Analysis emphasizes balance—technical excellence paired with soft skills navigates organizational complexities.
Pathways to Improvement and Exit Considerations
Improvement pathways include feedback loops: rating systems in tools like conference apps aggregate insights, informing enhancements. External perspectives, like articles on engineering misconceptions, offer fresh viewpoints.
When irreconcilable, exits—internal or external—rejuvenate careers. Market challenges notwithstanding, skill diversification bolsters options.
In conclusion, viewing codebases as crime scenes unveils systemic flaws, empowering engineers with strategies for navigation and reform, ensuring professional fulfillment amid adversities.

[DevoxxGR2024] Small Steps Are the Fastest Way Forward: Navigating Chaos in Software Development
Sander Hoogendoorn, CTO at iBOOD, delivered an engaging and dynamic talk at Devoxx Greece 2024, addressing the challenges of software development in a rapidly changing world. Drawing from his extensive experience as a programmer, architect, and leader, Sander explored how organizations can overcome technical debt and the innovator’s dilemma by embracing continuous experimentation, small teams, and short delivery cycles. His narrative, peppered with real-world anecdotes, offered practical strategies for navigating complexity and fostering innovation in a post-agile landscape.
Understanding Technical Debt and Quality
Sander opened by tackling the elusive concept of software quality, contrasting it with tangible products like coffee or cars, where higher quality correlates with higher cost. In software, quality—encompassing maintainability, testability, and reliability—is harder to quantify and often lacks a direct price relationship. He introduced Ward Cunningham’s concept of technical debt, where initial shortcuts accelerate development but, if unaddressed, can cripple organizations. Sander shared an example from an insurance company with 18 million lines of COBOL and 12 million lines of Java, where outdated code and retiring developers created a maintenance nightmare. Similarly, at iBOOD, a patchwork of systems led to “technical death,” where maintenance consumed all resources, stifling innovation.
To mitigate technical debt, Sander advocated for continuous refactoring as part of daily work, rather than a separate task requiring approval. He emphasized finding a balance between quality and cost, tailored to the organization’s goals—whether building a quick mobile app or a long-lasting banking system.
The Innovator’s Dilemma and Continuous Renovation
Sander introduced the innovator’s dilemma, where successful products reach a saturation point, and new entrants with innovative technologies disrupt the market. He recounted his experience at a company that pioneered smart thermostats but failed to reinvent itself, leading to its acquisition and dissolution. To avoid this fate, organizations must operate in “continuous renovation mode,” maintaining existing systems while incrementally building new features. This approach, inspired by John Gall’s law—that complex systems evolve from simple, working ones—requires small, iterative steps rather than large-scale rebuilds.
At iBOOD, Sander implemented this by allocating 70% of resources to innovation and 30% to maintenance, ensuring the “shop stays open” while progressing toward strategic goals. He emphasized the importance of defining a clear “dot on the horizon,” such as iBOOD’s ambition to become Europe’s leading deal site, to guide these efforts.
Navigating Complexity with the Cynefin Framework
To navigate the chaotic and complex nature of modern software development, Sander introduced the Cynefin framework, which categorizes problems into clear, complicated, complex, and chaotic zones. Most software projects reside in the complex zone, where no best practices exist, and experimentation is essential. He cautioned against treating complex problems as complicated, citing failed attempts at iBOOD’s insurance client to rebuild systems from scratch. Instead, organizations should run small experiments, accepting the risk of failure as a path to learning.
Sander illustrated this with iBOOD’s decision-making process, where a cross-functional team evaluates ideas based on their alignment with strategic goals, feasibility, and size. Ideas too large are broken into smaller pieces, ensuring manageable experiments that deliver quick feedback.
Delivering Features in Short Cycles
Sander argued that traditional project-based approaches and even Scrum’s sprint model are outdated in a world demanding rapid iteration. He advocated for continuous delivery, where features are deployed multiple times daily, minimizing dependencies and enabling immediate feedback. At iBOOD, features are released in basic versions, refined based on business input, and prioritized over less critical tasks. This approach, supported by automated CI/CD pipelines and extensive testing, ensures quality is built into the process, reducing reliance on manual inspections.
He shared iBOOD’s pipeline, which includes unit tests, static code analysis, and production testing, allowing developers to code with confidence. By breaking features into small, independent services, iBOOD achieves flexibility and resilience, avoiding the pitfalls of monolithic systems.
Empowering Autonomous Micro-Teams
Finally, Sander addressed the human element of software development, arguing that the team, not the individual, is the smallest unit of delivery. He advocated for autonomous “micro-teams” that self-organize around tasks, drawing an analogy to jazz ensembles where musicians form sub-groups based on skills. At iBOOD, developers choose their tasks and collaborators, fostering learning and flexibility. This autonomy, while initially uncomfortable for some, encourages ownership and innovation.
Sander emphasized minimizing rules to promote critical thinking, citing an Amsterdam experiment where removing traffic signs improved road safety through communication. By eliminating Scrum rituals like sprints and retrospectives, iBOOD’s teams focus on solving one problem daily, enhancing efficiency and morale.
Conclusion
Sander Hoogendoorn’s talk at Devoxx Greece 2024 offered a refreshing perspective on thriving in software development’s chaotic landscape. By addressing technical debt, embracing the innovator’s dilemma, and leveraging the Cynefin framework, organizations can navigate complexity through small, experimental steps. Continuous delivery and autonomous micro-teams further empower teams to innovate rapidly and sustainably. Sander’s practical insights, grounded in his leadership at iBOOD, provide a compelling blueprint for organizations seeking to evolve in a post-agile world.
