  • What Software Development Techniques Have Been Proven To Work Best For You?

    Dec 14, 2023

    Over my career as a software developer, I've worked on teams that have utilized a wide variety of development methodologies and techniques. Some have been more effective than others in helping teams deliver high-quality software efficiently. Based on my hands-on experience, these are the software development techniques that have proven most successful for me.

    Agile Methodologies

    Agile methodologies like Scrum and Kanban emphasize delivering working software frequently, close collaboration between teams, and adapting to changing requirements. I've found agile techniques infinitely better than traditional waterfall development, where software isn't delivered until the final stages.

    Agile methods deliver tangible results often, keeping teams motivated. They facilitate rapid feedback so teams can continually refine and improve products. I've been part of multiple agile teams that reliably released high-quality updates every 1-2 weeks, something nearly impossible with rigid sequential waterfall development.

    Scrum Framework

    Of the various agile approaches, Scrum has been most transformative for teams I’ve worked with. Scrum emphasizes accountability, iteration, and flexibility through defined roles, responsibilities, and ceremonies like daily standups, sprints, reviews, and retrospectives.

    I find Scrum’s fixed-length sprints particularly useful for focusing team efforts and having a regular cadence for evaluating progress and gathering user feedback. Elements like the product backlog and sprint backlog also promote transparency.

    Overall, Scrum provides the structure and discipline teams need to ship and refine quality products rapidly. Most agile teams I’ve seen have adopted some flavor of Scrum.

    Continuous Integration

    Continuous integration (CI) has helped the development teams I’ve been on avoid many headaches that crop up when code integration is postponed. By merging developer contributions multiple times daily, CI catches issues early when they are simple to fix.

    Without CI, teams can end up with long, difficult debugging sessions trying to identify issues that manifest when large changes get integrated. CI tools automatically run unit and integration tests with each merge too, further validating quality.

    The teams I’ve worked with that didn’t adopt CI often struggled with stability. Continuous integration is now a standard best practice I insist upon no matter what software methodology a team follows.

    Test-Driven Development

    Test-driven development (TDD) is another modern development staple I now consider essential. When programmers write tests first and aim for high test coverage throughout development, the end product is much more reliable and maintainable.

    TDD does require more upfront effort than jumping straight into coding. However having confidence that a comprehensive automated test suite will catch unintentional regressions makes continuous delivery of new features possible.

    I ensure TDD is a priority whenever I'm leading greenfield software projects now. And I advocate adding tests to legacy code before attempting significant modifications. The benefits of TDD in enabling agility and stability cannot be overstated.

    DevOps Practices

    While not exclusively tied to development, DevOps practices like infrastructure-as-code, extensive automation, and site reliability engineering (SRE) principles transform how modern software teams operate.

    DevOps tooling lets programmers deploy and update cloud-based systems without burdening ops teams. Automated monitoring provides visibility into production services. SREs focus on reliability and rapid recovery.

    Together these let developers own services end-to-end. Teams waste less time on repetitive tasks or finger-pointing during outages. They can deliver innovations faster without jeopardizing stability.

    Incorporating DevOps best practices has undoubtedly made the software teams I’ve worked with more autonomous, productive, and responsive. Companies struggling with cumbersome release processes should make adopting DevOps a priority.

    Code Refactoring

    Code refactoring is an often overlooked technique with major quality-of-life improvements for development teams. Dedicated refactoring efforts tune and streamline code bases, removing duplicate logic, improving readability, and making future changes less troublesome.

    In established code bases without refactoring, developers waste massive amounts of time understanding obtuse legacy logic or working around suboptimal architectural decisions. Technical debt accumulates insidiously.

    Setting aside time regularly for refactoring clears away this waste strategically. Teams experience boosted productivity almost immediately. Dedicated refactoring sprints let programmers tidy up systems without business stakeholders tapping their feet.

    Lean Software Development

    Concepts from lean manufacturing like eliminating waste have applications in software development. Lean software development aims to eradicate activities that don’t directly contribute value for users, like over-engineering, confusing documentation, or bureaucratic processes.

    I embrace lean principles by advocating for strict prioritization, minimal documentation, and simplifying routines that slow teams down without commensurate benefits. Non-code tools that enable collaboration and automation are winners here too.

    For example, chatbots that help on-demand access to project info developers stay productive. Automating deployment workflows eliminates wait times. Tasks like manually updating records should be extremely low priority.

    Apply lean thinking to regularly identify and trim superfluous activities and software teams suddenly have excess capacity. That time can be invested into quality improvements that do provide end-user value.

    Rapid Application Development

    For projects where speed-to-market is critical, rapid application development (RAD) techniques help launch basic viable products quickly. RAD emphasizes prototyping and iterative development with heavy user participation throughout.

    My teams leverage RAD principles to deploy initial web apps and services in just days or weeks. These early versions intentionally only implement the absolutely essential features. Additional functionality gets added later based on user feedback once live.

    Skipping steps like detailed requirements gathering and technical specifications - unnecessary early on - accelerates development. We focus documentation efforts only on critical integration points and architectural decisions as well.

    RAD works extremely well when launch timing is important, like for events or piloting innovative ideas. We can gather user input to refine subsequent versions. By staging sophistication, technical risks are minimized too.

    Incremental Development

    Incremental software development approaches closely align to agile values, breaking monolithic applications into independently releasable modules that accrue capabilities over time. Each increment builds upon the last until the full system envisioned gets implemented.

    On past projects with unclear long-term requirements or high complexity, I’ve championed incremental techniques to great success. User feedback informs ongoing development priorities dynamically. And focusing design and planning on smaller pieces keeps efforts grounded.

    I encourage starting with the riskiest architectural elements and foundational utilities first. As increments accrete, capabilities build up meeting initial needs while keeping future expansion possible. Incremental development sets up teams to iterate rapidly as product visions crystallize.

    Spiral Model

    For software projects with high risks, significant unknowns, or research elements, derivations of the spiral model help guide exploration efforts effectively. The spiral model prescribes a series of iterations where each loop focuses on identifying and mitigating risks around major milestones.

    On innovative projects, my teams minimize upfront planning and architecting. We rough out major capability groups and research priorities instead. As we investigate risks and unknowns, we steadily elaborate detailed requirements, prototypes, and designs just for upcoming increment(s).

    This experiential approach ensures efforts stay targeted on the most critical uncertainties first. Teams organically grow an understanding of challenges and refine solutions. By deferring decisions as long as practical, we have more data to make wise technology and implementation choices later.

    Kanban System

    While Scrum works well for teams with steady incoming work requests, teams that handle unpredictable user requests and support tickets often track better with Kanban. Kanban boards visually represent workflow states with work-in-progress limits that enhance focus.

    For my product support and operations engineering groups, Kanban systems provide flexibility to handle varying demands efficiently. Work-in-progress limits discourage individuals from multitasking excessively. Tracking cycle time histograms helps identify process bottlenecks for improvement.

    I like Kanban for its simplicity too. New teams can implement Kanban with minimal training and see benefits quickly. The visibility Kanban provides into throughput and stability gives leadership actionable metrics as well. The Kanban Method complements other development best practices nicely.

    Feature-Driven Development

    For building large-scale systems, feature-driven development (FDD) offers effective guidance. FDD breaks products down into client-valued functions as the central organizing principle. Feature teams then plan and execute small work packets in priority order with centralized coordination.

    I currently help manage a portfolio of backend services powering a high-traffic website using FDD with great success. Independent feature teams can deliver rapidly. Shared architectural ownership and automation keep services aligned cleanly.

    FDD also scales well organizationally. As additional feature teams get added, productivity grows linearly without significant coordination overhead. New services integrate seamlessly. Reusing domain models and components accelerates implementations too. Our systems expanded 10x in two years without growing technical debt or fracturing systemically.

    Extreme Programming

    Extreme programming (XP) takes common best practices like continuous integration, TDD, and pair programming to their logical extremes. The combination has exceptional outcomes - very high-quality systems developed sustainably at velocities most methodologies can’t match.

    My most productive teams practiced a refined XP emphasizing automated testing, evolutionary architecture, and ruthless prioritization. Even with complex backend systems, continuous deployment was the norm. Developers wrote tests for all new code ensuring 0 regression defects for years.

    Such hyper-efficient reliability comes at a cost though. XP expects senior developers and discourages overcommitting. Scheduling needs slack for unforeseen issues. Technical debt, bad multitasking, and poor communication get magnified painfully. Done right, however, XP sets a supremely high bar that all teams should aspire towards.


    Modern software teams have access to proven techniques like agile methodologies, CI/CD, DevOps, and more that enable remarkable outcomes. But holistic mastery doesn’t come easy. Practices like Scrum, XP, or Kanban present their own learning curves. Layering too many advanced tactics at once can even backfire.

    My recommendation for teams new to modern development practices is to pick 1-2 techniques that address your most pressing struggles. Focus on translating principles into behaviors that soon become habits. Allow plenty of time for learning before assessing results.

    Once practices firmly take root, define quantitative metrics to track efficiencies. Shorten feedback loops and amplify benefits by pilot testing additional techniques selectively. But restrain adoption rates to what your organizational culture can sustain.

    Great software gets built iteratively - the same applies to incorporating its enabling practices. But stick to it, learn from failures, and celebrate small wins. Compounded over the years, this chart is a path to excellence your whole team can be proud of.


    Which agile methodology is most widely used?

    Scrum is the most commonly used agile approach with over 70% of agile teams adopting the Scrum framework. Scrum's lightweight process, fixed work cycles, and clearly defined roles resonate well across organizations and team sizes.

    How does test-driven development actually work?

    With TDD, programmers first write automated tests for incremental units of functionality before writing implementation code. Existing tests then continuously validate each code change. This repeated red-green testing rhythm enables very high test coverage and reliable code.

    What are the main benefits of continuous integration?

    By merging developer code contributions multiple times daily, teams catch integration issues immediately when easiest to fix. Automated testing also validates changes, further improving quality. Developer productivity increases from eliminating messy merges and lengthy debugging.

    Does adopting DevOps require complex infrastructure modifications?

    DevOps practices like infrastructure-as-code and extensive automation works with both legacy and cloud-based systems. Start by adding CI/CD pipelines, monitoring and orchestration tools incrementally. You can realize huge efficiency gains without major architectural overhauls.

    Which software development methodology is the fastest?

    Rapid application development (RAD) approaches emphasize very short cycles - days or weeks - to launch functioning software swiftly. RAD teams then refine products iteratively with user feedback. The tradeoffs come in less upfront planning and infrastructure investments.

    What are the main advantages of incremental development?

    Incrementally growing software capabilities over multiple smaller deployments lets teams adapt designs, features and technical choices continuously based on user feedback. Early production-ready builds also establish real-world viability faster, minimizing overall risk.

    In what scenarios are Lean software principles most applicable?

    Lean software concepts help eliminate activities that don’t directly deliver end user value - like over-engineering, complex processes, and excessive documentation. Prioritizing user outcomes over team centric practices maximizes return on effort.

    What are the differences between Scrum and Kanban methodologies?

    Scrum follows structured, time-bound sprints for new development efforts. Kanban promotes continuous delivery using visual signals and work-in-progress limits - an approach that complements Scrum nicely for production support workstreams.

    How does feature-driven development scale for large programs?

    Prescribes decomposing programs into client-valued functions delivered by independent, focused feature teams. High-bandwidth coordination and architectural consistency keep the overall effort aligned. Adding more feature teams drives productivity linearly.
