How to build a high-performing software development team: 7 battle-tested tips from a CTO

Over the years, I’ve seen brilliant ideas fall apart because the development team wasn’t set up to succeed.

The real problem is that a lot of companies focus too much on tools and methodologies while ignoring the basics.

They hire reactively, rely on shaky reporting, and expect people to somehow “figure it out” as the project grows in scope and scale. And then they’re surprised when small issues turn into huge delays.

High-performing development teams aren’t built by accident.

You create them through clear structure, honest communication and processes that support your people instead of slowing them down.

In this article, I’ll share the 7 lessons that helped us get DECODE to where we are today.

I’ll cover how to hire the right people, structure your team, stay adaptable as your company grows, and much more.

Let’s dive in!

Keep your hiring process simple

I’ve learned that hiring works best when the process is simple and honest. That’s why we keep our processat DECODE straightforward.

No tests, puzzles, or endless interview rounds. Just two conversations that give us a clear picture of how someone thinks and whether or not they’re a fit.

The first interview is a conversation about real experience. We go through past projects, decisions they made and how they approached tricky parts of the work.

It’s relaxed on purpose. People do their best when they don’t feel like they’re being tested.

Then, if a candidate passes the bar, we move to the second interview. This one goes deeper.

We talk about how they solve problems, how they communicate when things get unclear and whether our values match.

Cultural fit matters because it shapes how the team works day to day. And no amount of technical skills can make up for a toxic personality.

Here’s what you should do:

• 2 clear interviews – Focused on real projects and how someone thinks.
• Judge cultural fit – Look for people who naturally work the way you do and share your values.
• A relaxed environment – Candidates should feel comfortable enough to show their real self.
• No tricks – Avoid convoluted LeetCode tasks that say nothing about someone’s real skills.
• Consistent structure – Everyone goes through the same steps, which keeps decisions fair.
• Clear ownership – Each interview should have a defined owner so the process stays predictable as you scale.

Keeping the process this lean makes hiring fair and predictable. Candidates know exactly what to expect, and the team knows what signals to look for.

It also scales well. As we grew, we kept the same two-interview flow and added more structure around who leads each stage so decisions stay consistent.

Pick the right team structure

Your team’s structure decides how smoothly it actually works.

I’ve learned you can’t copy a structure from another company. You need to shape it around your own goals.

You should look at a few things before deciding on a team pattern.

First, how complex is the work? Deep technical challenges need specialists who understand the problem inside out. Generalists struggle when the work gets too nuanced.

Then, how stable is the scope? Specialist setups work well with clear requirements. Fast-changing projects fit generalists or hybrid teams that can switch direction quickly.

And then, where are you in the product lifecycle? Early MVP work needs generalists who can build across the stack. Scaling usually requires specialists. Maintenance works best with small hybrid teams that know the system well.

Most of the time, your team will fall into one of 3 patterns:

• Technology (specialist) teams – These are deep technical teams focused on areas like backend, mobile, QA or DevOps. They’re great when you need depth, predictability and a lot of technical consistency.
• Product (cross-functional) teams – Small, autonomous teams that include engineering, design and QA. They own a product area end to end. They’re fast, flexible and perfect when you want quick delivery and fewer handoffs.
• Matrix teams – A mix of both. Engineers report to a specialist lead but work in cross-functional squads. This gives you depth and flexibility at the same time. It works well on large projects where one structure alone won’t fit every need.

To keep things simple, stick to a few key principles:

• Keep teams small – 2 to 7 people is the sweet spot.
• Make ownership clear – Everyone should know exactly what they own.
• Stay cross-functional whenever possible – It makes handoffs seamless and speeds up delivery.
• Review your structure regularly – What works for a small team, won’t work for a big one.

Don’t treat the team structure as fixed. It should change as your company grows.

Your job is to make sure the team setup always fits the work, not the other way around.

Set up and document essential processes from the start

When you have a small team, it’s easy to believe you don’t need documentation.

Then more people join or the scope grows and suddenly everyone is asking the same questions. I’ve learned it’s easier to set up the basics early than to untangle chaos later.

Start with the workflows that move code from idea to production. You want to get the basics right from the start.

We document branching rules, review steps, testing expectations and how deployments work. A new engineer should be able to follow the flow without guesswork as soon as they join.

Coding standards matter just as much. Naming, file structure, how we comment, how we format code.

Your project management approach needs the same clarity.

Whether it’s Scrum, Kanban or a hybrid, the team needs to know how work gets planned, prioritized and tracked. You also need to define who approves what, how decisions get made and where issues get escalated.

Here are the basics I recommend you document early:

• Core development workflows and CI/CD pipelines – How code moves from concept to production.
• Branching and review rules – Who reviews what and when.
• Testing expectations – When QA gets involved and what gets tested first.
• Deployment steps – Who triggers releases and how we verify them.
• Coding standards – Naming, structure and conventions that keep things consistent.
• How we plan work – Sprint routines, planning rules, and prioritization.
• Decision-making – Who has the final call in each area.

We regularly review and update documentation when something changes.

And one important rule you should follow: only document processes that solve a real problem. If I can’t explain why a process exists, we don’t keep it.

Create an honest reporting system

Good reporting isn’t about making things look perfect. It’s about staying as close to reality as possible.

I’ve seen too many projects drift into trouble because early reports were softened or risks were delayed. That “honeymoon phase” optimism feels harmless at first, but it hides real issues until all the easy fixes don’t work anymore.

Start by defining what “on track”, “at risk” and “off track” actually mean. Without clear rules, people will fill the gaps with guesswork.

At DECODE, we back every status with facts. Hours used, percentage of work done, and the time left. If 80% of the time is gone and only 40% of the work is finished, the project is not green, no matter how confident someone feels.

I also pay attention to small signals. A shift in scope, someone struggling, an unexpected client change.

These often matter more than big issues because they show up earlier. Asking “Is the plan still realistic?” keeps you ahead of problems instead of reacting when it’s already late.

Here’s what an honest reporting system looks like for me:

• Clear definitions – Everyone knows what green, yellow and red mean.
• Data behind every status – No gut feelings, just actual numbers.
• Early risk reporting – Risks are opportunities to fix things while our options are still open.
• Regular check-ins – Short, focused updates to confirm if the original plan still makes sense.
• Supporting the messenger – When someone flags a risk, I thank them, not blame them.
• Team-wide transparency – Everyone sees the same data, not just management.

I’ve learned that once reporting becomes a fear-driven activity, people stop telling you the truth. And when that happens, you lose control of the project.

Honest reporting doesn’t eliminate problems. It makes them visible early, when they’re still small and fixable.

And that’s what keeps you in control.

Encourage open and honest communication

If people don’t feel safe speaking up, problems grow faster than you can fix them.

I’ve seen people stay quiet because they didn’t want to sound negative or slow everyone else down. But, that’s what creates real risk.

So I try to make it clear that raising concerns is normal.

At DECODE, we treat early problems as a sign the system is working, not failing. When someone calls out a risk, our reaction is “Thanks for flagging it. Let’s look at it together,” not blame or pressure.

Clear communication also keeps collaboration smooth between different teams or departments. Design, product and engineering will always have different viewpoints, so it’s important they openly discuss them.

Misunderstandings usually come from poor assumptions, not a lack of skill. Structured communication reduces that friction and keeps everyone on the same page.

Here’s what we focus on to keep communication honest and healthy:

• Build a culture where honesty is safe – People shouldn’t fear saying a project is at risk. When honesty is punished, problems surface too late to fix cheaply.
• Have open one-on-ones – I ask questions like “What makes it hard to speak up?” or “Where does communication break down?” Then I address the patterns, not the individuals.
• Create a shared language – We use simple, consistent terminology across design and engineering. This is one of the biggest factors in reducing confusion between teams.
• Encourage cross-functional communication – Small, cross-functional teams move faster because designers, engineers and QA are in touch from the start.
• Use a buddy system for new hires – It gives them a safe place to ask “obvious” questions and lowers the barrier for speaking up as they join complex projects .

Good communication isn’t just a soft skill.

It directly affects delivery, retention and how quickly the team can spot and fix problems. When people can speak up without fear, everything else gets easier.

Optimize handovers between teams

Handovers are one of the easiest places for projects to lose momentum.

I’ve seen this happen often between design and engineering.

Most issues weren’t technical. They came from unclear expectations and assumptions on both sides.

That’s why we define how handovers will work before a project starts. Everyone knows what gets transferred, in what format, and who’s responsible for sharing it.

This removes a lot of confusion and stops teams from guessing what the “other side” meant.

Documentation is key to good handovers. Keep a record of decisions, open issues, blocked work and context in the same tools your team already uses.

Here’s a couple of the most important tips to avoid “handover wars“:

• Set clear handover requirements – Define exactly what a handover must include, like user flows, edge cases and known risks and limitations
• Use a single source of truth – Store all final designs, specs and decisions in one shared place to avoid confusion and make it easy for new team members to jump in.
• Make sure different teams review work together – Pair the documentation with a structured demo so everyone can align on flows, decisions and risks.
• Make ownership explicit – Make one person responsible on each side for confirming the handover is complete and nothing is unclear or missing.
• Reduce assumptions – Shared terminology between design and engineering removes a lot of friction before it can impact your project.

Good handovers give the next team what they need so they can get to work right away, not spend time guessing what the previous team meant.

It’s one of the easiest ways to avoid delays and keep the team focused.

Don’t be dogmatic

This is the most important tip I can give you when building a development team: don’t be dogmatic.

Rigid processes break the moment things get messy. When teams follow a framework blindly, they stop thinking and the process becomes the goal instead of the outcome.

And that’s when projects slow down.

At DECODE, we use whatever works for the project, not whatever a book says should work. Our processes are lightweight and adaptable. Here’s how I think about it:

• Treat frameworks as tools – Use them when they help, drop them when they don’t.
• Experiment in small cycles – Time-box trials so the team can learn without disruption.
• Avoid cargo culting – Don’t copy what big companies like Google or Meta are doing unless it actually fits your situation.
• Adapt based on evidence – Make changes because the team needs them, not because a method says so.
• Review processes often – Processes should evolve with the product and the team.
• Stay grounded in outcomes – If it improves delivery, quality or communication, keep it. If it doesn’t, remove it.

We adjust processes for different projects, when the scope shifts or when our current approach stops delivering results.

I encourage you to experiment. Try a new planning rhythm for a few weeks. Adjust standups. Change how you write tickets.

And as always, listen to your team.

Do they complain that daily standups are too long? Shorten them. Or maybe that they end up covering the same topics in sprint reviews and retrospectives? Drop one.

Your goal should never be to perfectly follow Scrum, Kanban, or any other methodology. You need to be flexible and find a rhythm that helps your team deliver faster.

Keep your core processes steady and adjust the details as your needs change. Don’t suddenly make huge changes unless they’re absolutely necessary.

And if you do have to make them, take the time to plan them before you jump in. Remember: slow is smooth, smooth is fast.
