You’ve got a CRM full of customer data. A separate finance system. Marketing running on its own platform. And when someone asks for a single view of business performance, the answer is: “We’ll need to pull that together manually.” Sound familiar?
Data silos are one of the most common blockers we see in organisations trying to become more data-driven. According to a Harvard Business Review survey, 84% of executives say their businesses suffer from the negative effects of siloed data, and IDC estimates companies lose between 20% and 30% of revenue each year due to inefficiencies they create. That’s a significant drag on any business.
The good news is that eliminating silos doesn’t have to mean a massive, expensive overhaul. Here are six practical steps we’ve seen work well.
1. Map What You Actually Have
Before you can fix anything, you need to know what you’re dealing with. Start by cataloguing where your data lives: which systems, which teams, and what data they hold. You’ll almost certainly find surprises. In our experience, most organisations have more data than they realise, much of it sitting unused. In fact, research suggests around 55% of enterprise data is “dark”, stored but never accessed.
A simple spreadsheet or data inventory is fine at this stage. You’re not looking for perfection, just a clear picture of the landscape.
2. Treat This as a People Problem First
Data silos often exist because teams built their own systems to solve their own problems, and over time those systems drifted apart. That means breaking them down is as much about culture and collaboration as it is about technology.
Get leadership aligned early. If different departments see data sharing as a threat to their autonomy (or their headcount), progress will stall. Frame the conversation around what everyone gains: faster decisions, less duplicated effort, better customer experiences.
3. Prioritise the Most Painful Silos
Don’t try to integrate everything at once. Instead, ask: where does the disconnect between systems cause the most friction right now? Maybe it’s the disconnect between sales and finance that means invoices are always late. Maybe it’s the gap between marketing and customer service that means you’re sending promotions to people who have just complained.
Start there. Quick wins build momentum and make the case for further investment.
4. Choose the Right Integration Approach
There’s no one-size-fits-all answer here. Depending on your systems and budget, you might look at API-based integrations between specific tools, a data warehouse or data lake that pulls everything into one place, or a middleware platform that sits between systems and keeps them talking.
We’d caution against the temptation to buy a shiny platform and expect it to solve everything. The technology is rarely the hard part. Integration projects fail most often due to unclear requirements, poor data quality, or lack of ownership, not the tools themselves.
5. Establish Clear Data Ownership
Every dataset should have an owner: someone responsible for its quality, access, and upkeep. Without this, integrated data quickly becomes unreliable. You end up with three slightly different versions of “customer” because no one agreed on the definition.
Data governance doesn’t have to be complicated. Even a simple set of agreed definitions and a named person accountable for each core dataset goes a long way.
6. Build the Habit of Sharing Data
The final step is cultural. As you break down the technical barriers, actively encourage teams to share insights across departments. Regular cross-functional reviews, shared dashboards, and joint planning sessions all help embed data sharing as a normal part of how the business operates, rather than a special project.
We’ve seen organisations transform their decision-making not by investing in complex technology, but simply by getting the right people in the same room looking at the same numbers.
Start Small, Think Big
Breaking down data silos is a journey, not a one-time project. The organisations that do it well focus on incremental progress: fix one painful integration, build trust, then move to the next. Over time, the compound effect is significant.
If you’re wrestling with disconnected data and aren’t sure where to start, we’d love to help you think it through. Sometimes a fresh pair of eyes on the problem makes all the difference.
