Modern Data Architecture Planning

Build the foundation your data deserves.

Every analytics initiative, AI investment, and modernization effort runs on the same foundation: your data architecture. If that foundation is outdated or misaligned with where you're headed, even the best technology won't help. SEI helps organizations design scalable, governed data architectures that support how you operate today and scale for what's ahead.

About SEI

Architecture that earns its keep

Great data architecture is about making the right decisions in the right order — aligning your business priorities, governance requirements, and technology choices before a single line of code is written. Whether you’re rationalizing a fragmented data estate, preparing for AI workloads, or building a cloud-native platform from the ground up, we design architectures that are built to perform, scale, and govern.

Real clients, real results

A well-designed data architecture pays dividends across your entire organization. Here’s what thoughtful, strategic architecture work has delivered for SEI clients.

$1M

Revenue generated within the first year after developing a cloud-based customer data platform for a national real estate firm

80%

Reduction in missing and discrepant data across a client's enterprise, achieved through a redesigned governance framework and structured validation processes

250%

Growth in data stewardship actions per quarter, reached with half the number of Data Stewards by redesigning and optimizing the operational model.

The data architecture gap is real — and it's getting harder to ignore

Organizations are investing heavily in AI and analytics, but most still lack the data foundations to make those investments pay off.

7% of enterprise organizations report their data is fully ready for AI adoption, while more than a quarter say their data is not very or not at all ready.

44% of enterprises named data quality as their single biggest obstacle to AI success in 2025 — more than double the 19% who said so in 2024.

78% of enterprises manage data across at least ten different platforms, showing that even companies that have updated one system still face challenges with data sprawl.

Have questions about modern data architecture?

What is modern data architecture, and how is it different from traditional approaches?

Modern data architecture is designed to handle the realities of today’s business — diverse data sources, real-time analytics needs, cloud-native infrastructure, and AI workloads. Where traditional architectures prioritized structured storage and batch processing, modern approaches emphasize flexibility, scalability, governance, and the ability to evolve alongside the business. It’s less about a single stack and more about a coherent, adaptable framework.

How does data architecture connect to AI and analytics readiness?

What does a data architecture engagement with SEI look like?

We start by understanding where you are: your current data estate, your governance posture, and your strategic priorities. From there, we develop a target-state architecture and a sequenced roadmap to get you there. We stay engaged through implementation, adapting as your needs evolve. You’ll never get a one-size-fits-all blueprint from us.

We already have a data warehouse. Do we still need this?

Possibly, it depends on where you’re trying to go. A legacy data warehouse may be doing its job well today but fall short when you need real-time analytics, multi-cloud flexibility, or AI-scale data pipelines. We assess what you have, identify the gaps, and help you determine the most pragmatic path forward. Sometimes that means building on what exists. Sometimes it means something more fundamental.
