Are data silos holding your business back? You are not alone. Research shows that 77% of enterprises state that silos prevent them from performing real-time analytics and making data-driven decisions. Therefore, the goal is simple: eliminate data silos.
Your enterprise is carrying years of accumulated systems (ERPs, CRMs, legacy databases, departmental tools, etc.) with each of them holding fragments of business data. The result is a level of enterprise data fragmentation and siloed processes that make it near-impossible to achieve end-to-end digitisation, advanced analytics, or AI at scale.
At this stage, it’s only natural to consider a total overhaul. However, a better solution is available.
Why the 'Replace Everything' Instinct Fails
The ‘replace everything’ mantra makes sense on the face of it. After all, technology has evolved greatly since your enterprise introduced its current ERPs and related systems. A fresh start would give you an opportunity to ensure that all systems and data reflect the current climate.
In reality, though, this approach is slow, expensive, and risky. The operational disruption is often far greater than organizations forecast, which can put the brakes on innovation for years. Moreover, legacy systems contain valuable business logic and operational knowledge. Losing this causes lasting problems, not least because migrating historic data at once may lead to compliance issues too.
The Real Culprit: Architecture, Not the Systems
A disconnection between systems within their architecture is usually the root of data silos rather than issues with isolated software. Therefore, improving connectivity between existing systems should be the priority over replacing them.
One of the big issues is that individual teams may optimize systems for their department rather than the enterprise-wide goals. Even simple issues like using different terms to define entities can cause silos as other teams struggle to find what they’re looking for. It additionally impacts reporting in a very big way.
If systems are not aligned with each other and the needs of the enterprise as a whole, integrations soon fall into the trap of becoming point-to-point. It disrupts the flow and interoperability of data, which ultimately costs you time and money.
A 3-Step Approach to Breaking Down Silos
Improving data systems rather than replacing them can deliver a smoother transition followed by superior outcomes. Here’s how to master the process in three easy steps.
Step 1 - Map your data landscape
The first step is to know where your data lives, who owns it, and what decisions depend on it. After all, you can't integrate what you haven't inventoried. Crucially, this should be viewed as a discovery initiative that provides the foundation for future success. It is not “just another IT project”.
You should identify every system that stores data (operational or customer-based) before documenting where critical data originates. It’s also important to identify any duplicate or conflicting sources of truth because you will subsequently want the entire enterprise to be served by one source of truth.
All current data quality, accessibility, and reporting should be assessed, with priority placed on high-impact data domains like customer data and finance data. Compliance and security considerations must be taken into account, too.
Step 2 - Build a unified data layer incrementally
The goal isn’t to replace entire systems with an overhaul; it is to focus on gradual changes that support data connectivity and eliminate data silos without potential disruption. The best approach is to start with one high-value use case (e.g., a single customer view). Prove the model before scaling.
Connections can be supported gradually through the use of APIs, integration platforms, and data pipelines. Legacy systems should remain operational while modern capabilities are layered on top. You should also focus on delivering measurable outcomes early, not least because demonstrating quick wins can secure future stakeholder buy-ins.
For the best results, you should try to create standardized data models and reusable integration patterns that can subsequently scale across departments. This subsequently facilitates iterative integrations structured around your business priorities.
Step 3 - Govern as you integrate
Finally, you must define data ownership and quality rules early. Otherwise, you're just moving the mess to a new location.
You will need to establish clear business definitions and consistent naming conventions to prevent future conflicts in data. Data quality, validation, and lifecycle management should be supported by clear rules for enterprise-wide consistency too. Document access, updates, and sharing protocols should be documented to prevent any future ambiguity or enterprise data fragmentation.
Strong governance surrounding enterprise data integration should be an ongoing operational capability, which extends to regular monitoring. It’ll prevent the recurrence of old silos and allow you to identify any future issues before they are allowed to cause major disruption.
What Good Looks Like
The global enterprise data management (EDM) market is worth over $120bn and is set to reach almost $300bn by 2034. This alone shows how important it is to manage yours well. So, what does a well-connected enterprise data system actually look like?
Here are the indicators that your enterprise data management is under control;
- Teams across all departments can access consistent, trusted, relevant data.
- Real-time data is available to support decision-makers at all times.
- New systems and software can be integrated without creating extra fragmentation.
- Reporting is fast and reliable across all areas of the business.
- AI tools and initiatives can be scaled with greater ease.
- Workflows encounter fewer delays, disruptions, and bottlenecks.
Ultimately, you can feel when the enterprise becomes more agile and facilitates collaboration with shared data standards.
Take Control with a Legacy System Audit Today
Recognising enterprise data fragmentation is one thing, but developing a strategy that can actively fix the problem is another altogether. A legacy system audit is the first step to success, providing a clear diagnosis of the situation. In turn, this will guide all future decisions on what changes are needed to eliminate data silos for good.
A legacy system audit is a diagnostic, not a commitment, and simply aims to provide clarity. Get in touch with our friendly experts to book yours today.
