How To Build A Strong Software Development Team

I’ve been leading SWE teams for over a decade now. As a Principal EM, I have one cardinal rule: The failures of my team are my failures. A strong engineering team doesn’t just happen, it’s built deliberately over time. To evaluate progress and level up, I focus on three core pillars that define a high-performing engineering team. Let’s break them down: 1. Delivering Value: The “Why” Behind the Work Your team exists to solve problems, ship features, and provide value. - Are we consistently delivering measurable results? - Are stakeholders confident in our output? - Does every sprint feel aligned with business goals? Value doesn’t mean just “shipping.” It means shipping the right things that move the needle for the business. 2. People Growth: Build for Today, Invest for Tomorrow Your team isn’t just delivering code, it’s a living system of people with potential. Ask yourself: - Are individuals engaged and growing? - Are we creating opportunities for junior engineers to step up? - Do team members feel empowered to share ideas and take ownership? High retention, strong morale, and skill growth are signs you’re on the right track. 3. Sustainable Quality: Long-Term Wins Over Short-Term Gains Shortcuts may feel tempting, but tech debt always comes knocking. - Are we balancing speed with quality? - Is technical debt under control? - Are we investing in processes and tools to sustain long-term success? The best teams create systems that grow with them, not against them. My role an Engineering Manager isn’t just to manage tasks. It’s to elevate the entire system—people, processes, and outcomes. When your team excels in all three pillars, you’re creating a high-performance team that can adapt, grow, and thrive. If you’re a developer, remember: Your work is more than just the lines of code you push. When you focus on delivering value, growing as a person, and maintaining quality, you’re not just leveling yourself up, you’re helping your entire team succeed. Keep asking questions. Keep learning. And most importantly, keep building.

Some teams look fast from the outside. But when you look closely, their real strength is not speed. It is design. Not just system design. Team design. The best engineering teams follow patterns that make both software and people work better together. → 𝐌𝐨𝐝𝐮𝐥𝐚𝐫 𝐀𝐫𝐜𝐡𝐢𝐭𝐞𝐜𝐭𝐮𝐫𝐞 • Break big systems into smaller services • Clear ownership reduces confusion and dependency chaos • Teams move faster when each module has a defined owner → 𝐎𝐛𝐬𝐞𝐫𝐯𝐚𝐛𝐢𝐥𝐢𝐭𝐲 & 𝐌𝐨𝐧𝐢𝐭𝐨𝐫𝐢𝐧𝐠 • Logs, metrics, and tracing create visibility • Teams can detect issues early and respond faster • Better transparency leads to stronger operational control → 𝐒𝐢𝐧𝐠𝐥𝐞 𝐑𝐞𝐬𝐩𝐨𝐧𝐬𝐢𝐛𝐢𝐥𝐢𝐭𝐲 𝐏𝐫𝐢𝐧𝐜𝐢𝐩𝐥𝐞 • Every component should do one job well • Focused ownership improves accountability • It also makes debugging and performance tracking easier → 𝐅𝐞𝐞𝐝𝐛𝐚𝐜𝐤 𝐋𝐨𝐨𝐩𝐬 • Strong teams improve through retrospectives and postmortems • Learning cycles help teams adapt as products evolve • Progress becomes continuous, not accidental → 𝐒𝐜𝐚𝐥𝐚𝐛𝐢𝐥𝐢𝐭𝐲 𝐛𝐲 𝐃𝐞𝐬𝐢𝐠𝐧 • Great systems are built for future growth • Great teams do the same with processes and structure • This prevents bottlenecks before they slow everything down → 𝐃𝐨𝐜𝐮𝐦𝐞𝐧𝐭𝐚𝐭𝐢𝐨𝐧 𝐚𝐬 𝐈𝐧𝐟𝐫𝐚𝐬𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞 • Decisions should be written, not just remembered • Shared knowledge improves onboarding and alignment • Good documentation protects momentum as teams grow → 𝐀𝐏𝐈 𝐅𝐢𝐫𝐬𝐭 𝐂𝐨𝐦𝐦𝐮𝐧𝐢𝐜𝐚𝐭𝐢𝐨𝐧 • Clear contracts reduce misunderstanding between services and teams • Structured communication improves collaboration • Everyone works with more clarity and fewer blockers → 𝐂𝐈/𝐂𝐃 & 𝐀𝐮𝐭𝐨𝐦𝐚𝐭𝐢𝐨𝐧 • Automation removes repetitive manual effort • Teams ship faster with more confidence • Reliable delivery creates consistency at scale →  𝐋𝐨𝐨𝐬𝐞 𝐂𝐨𝐮𝐩𝐥𝐢𝐧𝐠 • Independent services enable independent progress • Teams can deliver without waiting on everyone else • This unlocks real parallel development →  𝐑𝐞𝐬𝐢𝐥𝐢𝐞𝐧𝐜𝐞 & 𝐅𝐚𝐮𝐥𝐭 𝐓𝐨𝐥𝐞𝐫𝐚𝐧𝐜𝐞 • Strong systems recover from failure • Strong teams do too through backup ownership and cross skilling • Resilience keeps delivery stable during pressure The hidden truth is this: The way you design your systems eventually shapes the way your teams operate. And the way your teams operate will always show up in the architecture. Follow Umair Ahmad for more insights

Do you feel part of a real team? Or are there moments when you feel isolated, uncertain, and disconnected, even though you're surrounded by colleagues? In the early stages of my career, I had the simplistic view that bringing together a bunch of high achievers would naturally create an outstanding team. However, the reality was quite different. Instead of creating synergy, there was noticeable discord. The team didn't seem to gel; it was akin to cogs not aligning in a machine. Every top performer, exceptional in their own right, appeared to follow their own path, often pulling in different directions. The amount of energy and time lost to internal strife was significant, and the expected outcomes? They remained just that – expected. This experience was a clear lesson that the success of a team isn't merely based on individual talent; it's about harmony, alignment, and collaboration. With today’s workplaces being more diverse, widespread, digitized, and ever-changing, achieving this is certainly challenging. So, in my quest to understand the nuances of high-performing teams, I reached out to my friend Hari Haralambiev. As a coach of dev teams who care about people, Hari has worked with numerous tech organizations, guiding them to unlock their teams’ potential. Here are his top 5 tips for developing high performing teams: 1. Be Inclusive ↳Put a structure in place so that the most vocal people don’t suffocate the silent voices. Great teams make sure minority views are heard and taken into account. They make it safe for people to speak up. 2. Leverage Conflict ↳Disagreements should be encouraged and how you handle them is what makes your team poor or great. Great teams mine for conflict - they cherish disagreements. To handle disagreements properly make sure to separate discussion from decision. 3. Decision Making Process ↳Have a clear team decision-making method to resolve conflicts quickly. The most important decision a team should make is how to make decisions. Don’t look for 100% agreement. Look for 100% commitment. 4. Care and Connect ↳This is by far the most important tip. Teams who are oriented only on results are not high-performing. You need to create psychological safety and build trust between people. To do that - focus on actually knowing the other people and to make it safe to be vulnerable in front of others. Say these 4 phrases more often: ‘I don’t know’, ‘I made a mistake’, ‘I’m sorry’, ‘I need help’. 5. Reward experimentation and risk taking ↳No solution is 100% certain. People should feel safe to take risks and make mistakes. Reward smart failure. Over-communicate that it’s better to take action and take accountability than play it safe. Remember, 'team' isn't just a noun—it's a verb. It requires ongoing effort and commitment to work at it, refine it, and nurture it.

The best teams don’t always collaborate. They argue and lean into conflict. Here's what nobody tells you. Teams that never fail are teams that never grow. Think about it: → Poor collaboration kills potential → Missed deadlines crush motivation → Silent conflicts destroy trust 12 fatal mistakes that destroy teams (and what to do). 1. Too much harmony ↳ Conflict-free teams rarely innovate or grow ✅ Schedule monthly "challenge my thinking" sessions 2. The burnout blind spot ↳ High performance often masks imminent collapse ✅ Track team energy, not just productivity metrics 3. Praising completion over chaos ↳ Perfect execution kills creative problem-solving ✅ Reward teams who fail forward and learn fast 4. The documentation paradox ↳ More tools = less knowledge sharing ✅ Make 10-minute daily documentation non-negotiable 5. The hero syndrome ↳ Star performers can actually weaken the team ✅ Rotate challenges to build collective strength 6. Instant response culture ↳ Quick replies often mean shallow thinking ✅ Set 4-hour response windows for deep work 7. Meeting addiction ↳ Teams spend 70% discussing, 30% building ✅ Try half-day meeting bans for focused execution 8. Feedback phobia ↳ Annual reviews are already 11 months too late ✅ Build weekly 15-minute feedback loops 9. Priority paralysis ↳ When everything matters, nothing gets done ✅ Use the 1-3-5 rule: 1 must, 3 should, 5 could 10. The comfort trap ↳ Stable teams often signal stagnant teams ✅ Rotate roles quarterly to build adaptability 11. Success amnesia ↳ Teams forget what worked when pressure hits ✅ Create a 5-minute "win log" every Friday 12. The clarity illusion ↳ Everyone nodding doesn't mean everyone knows ✅ Test understanding, don't ask for agreement You don't need a title to transform your team. Every member has the power to spark change. Start small: → Pick one point → Champion it → Watch the ripple effect Strong teams aren't built through perfection. They're built through continuous learning. Your role matters more than you think. What would you add?

After 5 years at Amazon, I found 1 practice that builds the best software teams: I call it knowledge distribution. ► If your team relies on "tribal knowledge": ↳ Onboarding takes months instead of weeks. ↳ You're always one resignation away from disaster. ↳ Your best engineers burn out from being constant bottlenecks. ↳ Critical systems become "no-fly zones" that only a few understand. ► If your team is good at sharing knowledge: ↳ Bus factor becomes a strength, not a risk. ↳ New hires become productive in days, not months. ↳ Any engineer can debug any system (without pinging "the expert"). ↳ Your top talent can focus on hard problems instead of answering the same questions True engineering leadership does not mean you must be the only one knowing it all. It means ensuring everyone knows enough to make you redundant. The choice is yours: Be the engineer who's constantly needed Or build the team that doesn't need you.

Systems Thinking: The Productivity Paradox Imagine a riverside town struggling with seasonal flooding. To mitigate, they build higher levees, allowing them to expand housing and businesses into previously flood-prone areas. At first, flooding stops, and the town thrives. But over time, wetlands downstream erode, and floodwaters have nowhere to spread. When a major storm overwhelms the levees, the flooding is worse than ever. More levees and expansion seemed like progress… but the system fought back. Now, imagine a software company struggling with slow delivery. Customers complain. Revenue and reputation are at risk. Executives need a fix. Their answer? Hire more developers. At first, velocity increases. Features ship faster. But soon, delivery is slower than before the new team members were hired. Adding devs was supposed to speed things up (and did, briefly). But… the system fought back. Why Adding Developers Slows Things Down Fred Brooks wrote, “Adding manpower to a late software project makes it later.” Why? Communication grows exponentially. With 5 devs, you manage 10 communication links. With 10, it’s 45. At 20, it’s 190. More meetings, more dependencies, slower decisions. New hires aren't immediately productive. Senior devs have to help with onboarding. As the team grows, more code is written, leading to merge conflicts, longer pull request cycles, and WIP stuck in queues. More teams means unclear ownership, more handoffs, and more rework. What's The Solution? 1) Reduce WIP Too much WIP slows teams down. Before hiring, ask: Are we prioritizing finishing over starting? Can we reduce batch sizes? Can we use Kanban and/or Scrum to improve flow without adding people? 2) Think Structure, Not Size More devs means higher coordination costs. Instead, use Team Topologies. Stream-aligned teams own end-to-end delivery. Enabling teams improve developer focus. Platform teams reduce cognitive load. 3) Automate and Improve Code Quality Don't maximize team size, optimize the pipeline. Faster CI/CD reduces delays, automated testing prevents bug creep, and refactoring improves maintainability. 4) Use Modular Architecture A tightly coupled system slows everyone down. Shift to microservices or modular monoliths (single deployable units), use feature flags for incremental deployment, and apply domain-driven design (DDD) to define team boundaries. 5) Measure Outcomes, Not Headcount Leaders may wrongly assume more developers means more output, but real productivity is about flow efficiency. Instead of team size, track: Cycle time (how long it takes to ship), Deployment frequency (how often we deliver), and Lead time for changes (how fast we adapt). Systems, Not Silos When teams slow down, hiring feels like the obvious fix. But it should be the last resort, not the first instinct. Without systems thinking, hiring may have unintended consequences that ironically make things worse. Rethink how your system works... before the next storm.

𝐓𝐡𝐞 𝐏𝐨𝐰𝐞𝐫 𝐨𝐟 𝐈𝐓 𝐓𝐞𝐚𝐦 𝐀𝐮𝐠𝐦𝐞𝐧𝐭𝐚𝐭𝐢𝐨𝐧 (𝐓𝐡𝐢𝐬 𝐢𝐬 𝐰𝐡𝐲 𝐦𝐨𝐬𝐭 𝐭𝐞𝐚𝐦𝐬 𝐟𝐚𝐢𝐥 𝐭𝐨 𝐬𝐜𝐚𝐥𝐞 𝐨𝐧 𝐭𝐢𝐦𝐞.) Not about hiring faster. Not about filling empty seats. Not even about cutting costs. The real value sits deeper. Long before a developer writes a single line of code. I learned this by building global tech teams. Projects didn’t fail from lack of skill They failed from lack of the right support at the right moment. → 1. Start with team clarity — Define the gaps honestly. — Know what slows the team today. — Understand where expertise is missing. — This sets the right foundation. → 2. Choose specialists, not generalists — Pick the talent that fits the exact role. — Match skills with workload pressure. — Bring people who lift the team, not copy it. → 3. Integrate smoothly — Align tools and processes early. — Set communication rules clearly. — Treat augmented members as full teammates. — Momentum comes from unity. → 4. Scale only when needed — Grow the team during peak workload. — Reduce when pressure drops. — Keep the team lean, not overloaded. → 5. Maintain speed without burnout — Distribute tasks fairly. — Protect your core team’s focus. — Let specialists handle heavy lifting. → 6. Improve continuously — Review performance often. — Realign roles as projects evolve. — Strengthen collaboration as the product grows. Great engineering doesn’t come from hiring more people. It comes from hiring the right people at the right time. Team augmentation isn’t a shortcut. It’s a smart, flexible strategy. Ignore it, Your internal team struggles. Use it wisely, Your entire delivery pipeline transforms. P.S. Do most companies realize the true value of augmentation, yes or no?

I was asked the other day by a colleague what to watch out for when hiring an outsourced dev shop. For over 20 years, I’ve been hiring software developers. During this time, I’ve hired from the Philippines, Vietnam, Russia, Belarus, Ukraine, Poland, Brazil, Colombia, Bolivia, Mexico, Canada, and the U.S. The market is saturated with dev shops, making it challenging to distinguish quality ones from ones that are 💩 Here's what I shared with him: 1. Look Beyond the Sales Pitch Many dev shops have charismatic salespeople who promise the world. Instead, focus on the actual project team. Speak to the developers who will work on your project and interview them. Ensure they understand your objectives and can make strategic decisions independently. 2. Beware of Junior Developer Overload Some companies staff projects with a senior lead and numerous junior developers. While this can lower costs, it often leads to inefficiencies. Junior developers might delay work due to dependency on others. Prioritize teams with experienced developers who can progress without constant oversight. 3. Verify Expertise Avoid title inflation. Many bootcamp graduates or developers with a few years of experience are labeled as seniors. Request resumes and ensure the developers have substantial experience, particularly in the technologies you need. For instance, if you need Rust expertise, check for deep engineering experience in similar languages. 4. Understand Their Methodology Agile is ubiquitous, but its implementation varies. Ask potential partners how they prioritize tasks and define “done.” Ensure they have a clear process for progressing without daily management from you. 5. Emphasize Quality Assurance Quality should be a team responsibility, not just the QA role. Ensure the team practices thorough testing and code coverage. We just had a project with Salesforce where they require 75% unit test coverage - now that's a high bar for quality. 6. Assess Regional Strengths Different regions excel in various areas. For instance, Latin America has strengths in database and front-end work, while Eastern Europe excels in deep engineering and data science. Understanding these strengths can guide your decision. (I'm sure I'll get some shit for this, but that's what I've seen). 7. Avoid Rigid Specifications Some companies demand detailed specs upfront and build exactly to them, leading to endless change orders. Look for partners who focus on your objectives and adapt as needed. I hope these insights can help navigate the saturated developer market and choose a partner who truly understands and can achieve your goals.

Close Skill Gaps and Build Peak Performing Teams You have Defined the key Skills. You have Assessed the team’s Strengths and Gaps. Now it is time for the most important step: 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁. 3-Step approach to make it happen. 1) 𝗦𝗵𝗮𝗿𝗲 𝘁𝗵𝗲 𝗙𝗲𝗲𝗱𝗯𝗮𝗰𝗸 & 𝗥𝗲𝘀𝘂𝗹𝘁𝘀 Feedback is not just about pointing out gaps. It’s about creating clarity and alignment. Here is how to do it effectively: • Compare the Self-Assessment to Team Assessment. - Look for differences - great opportunity to uncover blind spots. • Start with Strengths. - Recoginize wins to improve receptiveness. • Pinpoint Opportunities. – These are not "weaknesses" but where improvement can lead to the most growth. • Give Examples! - Data alone may not stick. Highlight examples from real situations where skills were on display. When You are clear, specific, and encouraging, people will walk away from the conversation with clarity on what’s next. 2) 𝗖𝗿𝗲𝗮𝘁𝗲 𝗮𝗻 𝗔𝗰𝘁𝗶𝗼𝗻𝗮𝗯𝗹𝗲 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁 𝗣𝗹𝗮𝗻 Without a plan, feedback is just noise. Here is how to create a plan that drives action: • Co-Create the Plan. - Increase Buy-in by Collaborating to create a path forward. • List Specific Actions. - The more specific, the better. Avoid vague goals like “get better at communication.” Instead, “complete 2 workshops on conflict resolution this quarter” is clear and actionable. • Tap into Resources. - Support growth with tangible resources. --> Training --> Courses --> Workshops --> Certifications --> Special projects --> Mentoring Program --> Delegating your Responsibilities • Leverage Projects for Development. - Give team members "stretch assignments" that force them to use and develop the very skills they are building. When Your team member owns the plan, They own the results. 3) 𝗧𝗿𝗮𝗰𝗸 𝗣𝗿𝗼𝗴𝗿𝗲𝘀𝘀 𝗮𝗻𝗱 𝗖𝗲𝗹𝗲𝗯𝗿𝗮𝘁𝗲 𝗪𝗶𝗻𝘀 Growth requires consistent measurement and celebration. Here is how : • Set Milestones. - Define specific checkpoints to measure progress. • Provide Regular Feedback. - Ongoing feedback keeps people on track and engaged. • Track Key Metrics. - If You are measuring skills like problem-solving, track how it is improving through real-world application. • Celebrate Progress. - Growth should be recognized. It builds confidence and encourages continued effort. This process ensures that progress is visible and celebrated, Not hidden until the next review. Don’t just collect data on skills. Use it to build Your team into Peak Performers. What is one development action you’ll take for your team this week? P.S. If you’re thinking, "I don’t have time for all of this," start small. Have one 10-minute conversation with a team member this week. You will be surprised how far it goes.

The winner for best slides at #LeadDevBerlin came from 🐱 Denise Yu from HashiCorp, who spoke about levelling up your entire team, and avoiding “superhero” development. ⬇️ “Level Up the Whole Party, Not Just the Hero” • Uses the Pokémon metaphor of training one Pokémon vs. a collection: good leadership is a series of repeated and consistent behaviours. A well-balanced team is more effective than a single code hero. • Final Fantasy VII team reference: each team member has their own strengths, and 3 out of 4 would suffer if forced into one mould. • A balanced team includes varied demographics, thinking styles, experience levels, motivators, etc. • Take stock of your desired end state: your team should include a good mix of styles like teachers, specific tech stack expertise, carers, doers, etc. Create a map of needed expertise. • Expertise: “Novices only see what is there; experts can see what is not there” (Gary Klein quote). • Re: Expertise, Denise likes to ask: “How much cursed knowledge do you have?” (knowledge you gained without wanting to! 😅). • Theory of Proximal Development: do tasks you can accomplish with some assistance (not tasks you can already do or ones you can’t complete at all). • Identify where an engineer is now and where they want to be; map their progression with steps that involve only changing one thing at a time. • Go through a career matrix with each engineer, assessing their self-evaluation of abilities; set goals based on agreed gaps. • Use everyday decisions to incrementally advance your team. • Work distribution options: free-for-all (everyone picks tasks) vs. assigning every individual ticket. Best option: create norms around ownership, with initiative-based leads who can self-organise. • Assigning work is like giving experience points to different team members (RPG metaphor). • Repeatedly giving one star member the same tasks means losing opportunities to develop that skill in others. • Be willing to accept short-term slowdowns to achieve long-term speed and a balanced distribution of skills and expertise. (notes cleans up by ChatGPT) —— I loved Denise’s video games metaphor and found it enjoyable and impactful. I am to always lift up the team as well as the individual, but her reminder to not just lean on the same team member for the same tasks was something I will definitely carry forward. Thank you Denise for a great presentation!! Unfortunately I didn’t get many photos of her amazing Charmander slides but suffice it to say they were awesome! #EngineeringManagement
