Build an Enterprise Application Integration Strategy

Transform from chaotic disintegration to seamless integration.

Enterprises are entangled in application sprawl. The average organization uses close to 1,000 applications but over 70% of them aren’t fully integrated. Integration remains an afterthought, resulting in fragile point-to-point connections, brittle dependencies, siloed data – and missed opportunities: 95% of IT leaders cite integration as a barrier to AI adoption. Use our actionable research to connect systems with intention and create a scalable, flexible foundation for digital transformation and organizational agility.

Integrations are often done piecemeal, creating a spaghetti network of tangled connections that prevent the seamless sharing of data and workflows. Treating integration like a one-off task keeps your IT systems from evolving and hurts your organization’s ability to compete. IT leaders must approach integration as a continuous journey, shifting from reactive technical fixes to proactive, business-aligned integration.

1. Integration is not about connecting everything.

It’s about connecting the right things. Attempting to haphazardly integrate all your systems at once leads to big disappointment and rising costs. Focus on high-value integrations to solve real-world problems, lay a solid foundation from there, and expand incrementally. Start with something straightforward like API connections and tackle more complex orchestrations as your team gains experience.

2. The biggest integration failures don’t happen at go-live.

They rear their ugly heads much later, when a change in one system silently breaks an interface, or data drifts out of sync and nobody even notices. That’s why integration isn’t a “set and forget” item on your to-do list. It’s an ongoing practice that requires oversight, a strong testing regimen, and continuous monitoring.

3. Know when to reuse and when to retire stuff.

Reuse components wherever possible to accelerate integration and reduce costs. But don’t be afraid to let go of redundant or fragile integrations either. Deprecate old point-to-point scripts once a better integration solution is in place, to reduce overall complexity. Chase simplicity in design even as your application ecosystem grows.

Use this step-by-step framework to design an integration strategy that supports growth and resilience.

Our research offers a unified three-step methodology supported by two powerful resources: a comprehensive storyboard and a decision-support toolkit. Together, they lead you through the process of crafting a holistic integration strategy that can adapt to your organization’s changing needs.

  • Ensure each connection has a purpose by identifying where integrations will deliver value before choosing how to implement them.
  • Evaluate and select integration approaches for each use case based on variables such as messaging patterns, integration styles, and coupling (synchronous vs. asynchronous).
  • Avoid integration chaos with a repeatable strategy and testing plan built for change.

EXECUTIVE BRIEF

Analyst Perspective

Integrate to Innovate

Ibrahim Abdel-Kader

Treat integration as a continuous journey, not a one-off task. A flexible, holistic approach ensures that we connect systems in a way that can evolve with our business. This avoids creating new silos. No application gets left behind because we are always planning for the bigger picture and future changes.

In a mature IT environment, integration is not optional – it’s a sign of growth. When your systems seamlessly share data and workflows, your business can respond faster to opportunities and make smarter decisions grounded in real-time information. This unified IT landscape means that every efficiency gained in one department immediately benefits the whole company, breaking down silos. For an executive, that translates into greater agility and a competitive edge: integrated processes reduce delays, cut costs from duplicate efforts, and ensure that you’re fully leveraging every technology investment to drive innovation.

We chase simplicity in design even as our ecosystem grows. The good news: integration technology has come a long way. Today’s tools – from application programming interfaces (APIs) to integration platforms – are powerful and user-friendly, letting us simplify connections that used to be daunting. By using these advanced integration tools effectively, we turn a complex web into a clean, efficient flow.

Executive Summary

Your Challenge

Common Obstacles

Info-Tech’s Approach

Organizations treat integration as an afterthought, resulting in a fragile patchwork of systems:

  • Integrations are often done piecemeal (point to point), leading to a spaghetti network of connections with high maintenance overhead.
  • Data remains siloed in each application, causing duplicate efforts, inconsistent reports, and no single source of truth.
  • Without a unifying integration strategy, technology investments underdeliver on their promise.

Even when integration is recognized as important, hurdles persist when turning vision into reality:

  • Departments focus on only their own systems, and no one owns enterprise integration.
  • Years of one-off links result in brittle dependencies. The fear of breaking things stifles attempts to modernize integration.
  • Teams default to familiar methods (e.g. manual exports) due to lack of integration expertise or platforms. Security and data quality issues are left to be fixed “later.”

Use Info-Tech’s method to transform integration from a reactive afterthought to a proactive, value-driven practice:

  • Identify where integrations will deliver business value before choosing how to implement them. This ensures that each connection has a purpose.
  • Become aware and select the best integration approach for the enterprise using Info-Tech’s framework.
  • Establish guiding principles and testing requirements for integrations from the get-go, so they are reliable and withstand change.

Info-Tech Insight

Integration should be driven by business value, not just IT convenience. By focusing on high-impact data exchanges – and doing them in a secure and standardized way – you eliminate unnecessary silos and avoid over-complicating everything else. This targeted strategy yields a big return on integration investment (e.g. faster processes, better insights) without entangling your organization in unnecessary integration work.

Integration challenges derail digital and AI transformation

Modern enterprises deploy dozens, or even hundreds, of applications, but lack of integration is now a top barrier to digital success.

Integration challenges are hindering digital transformation for 83% of organizations.

95% of IT leaders report integration as a hurdle to implementing AI effectively.

These findings underscore the urgent need to tackle integration in a structured way. Companies that continue using ad hoc integrations face mounting operational drag and missed opportunities. In contrast, companies that master integration gain a foundation for faster decision-making and end-to-end customer experiences.

Integration complexity stifles innovation

  • With the average enterprise using close to 1000 applications, the need for integration cannot be more apparent.
  • However, over the past three years at least, more than 70% of applications have not been integrated, and only 2% of IT leaders have integrated more than half of their applications.

Companies report over-reliance on applications and too much disconnection between them.

46% of organizations are using 1000 or more applications.

71% of applications are not fully integrated or connected.

Tightly coupled approaches are not sustainable

While the substantial increase is impressive, 87% of organizations agree that API management could be improved.

40% of company revenue is generated from APIs and API-related implementations, up from 25% in 2018.

74% of organizations have IT systems that are overly dependent on one another.

Organizations need to be comfortable with integrating in different ways to drive more value from their applications.

Insight Summary

Overarching Insight
Integration should be driven by business value, not just IT convenience. By focusing on high-impact data
exchanges – and doing them in a secure and standardized way – you eliminate unnecessary silos and avoid over-complicating everything else. This targeted strategy yields a big return on integration investment (e.g. faster processes, better insights) without entangling your organization in unnecessary integration work.

Step 1 Insight
When integration is done right, it turns isolated software investments into a unified competitive advantage. The key is to integrate what matters most – the critical data and the processes that drive value – and do this in a governed, strategic way. Organizations that prioritize a clear integration strategy (e.g. targeted use cases, standard patterns, proper testing) eliminate
pain from silos, increase agility, and unlock rich insights – all without excessive complexity.

Step 2 Insight
Integration is not about connecting everything; it is about connecting the right things. Trying to integrate all systems at once or in a haphazard way leads to disappointment and high cost. The most successful organizations focus on high-value integrations that solve concrete problems, lay a solid foundation, and then expand.

Step 3 Insight
Integration is not a “set and forget” endeavor – it’s an ongoing practice that needs oversight. Many integration failures happen not at launch but later, when a change in one system silently breaks an interface, or data drifts out of sync without anyone noticing. That’s why a strong testing process and continuous monitoring are essential.

Tactical Insight
Integrate incrementally and celebrate progress. Integration capability matures over time. You might start with straightforward API connections and, as the team gains experience, tackle more complex orchestrations or real-time event streams.

Tactical Insight
Wherever possible, reuse components from one integration to another. On the flip side, do not be afraid to deprecate old point-to-point scripts once a better integrated solution is in place. Removing redundant or fragile integrations is just as important as adding new ones – it reduces complexity.

Blueprint Benefits

IT Benefits

Business Benefits

  • Simplified architecture and lower maintenance: By replacing ad hoc point-to-point links with a planned integration framework, IT reduces complexity. Fewer custom scripts and one-off fixes mean less time firefighting and more time on value-add development.
  • Increased reuse and faster delivery: With standard APIs and integration services in place, IT can reuse components for multiple projects. For example, once you have a customer information API, any new application that needs customer data will be able to
    plug in.
  • Improved data quality and security: A cohesive integration strategy improves overall data integrity. Data is validated and transformed consistently as it flows, reducing discrepancies between systems. It is easier to meet compliance requirements (e.g. GDPR, HIPAA) when integrations are managed systematically.
  • Faster process cycle times: Integrated processes are inherently quicker. This responsiveness can directly improve revenue (faster quote-to-cash means faster payments) and customer satisfaction (quick service delivery).
  • Enhanced customer experience: Customers increasingly expect a seamless journey, and integration makes this possible. A connected experience drives higher customer loyalty and a better net promoter score (NPS).
  • Operational agility and innovation: Once integration is in place, a business can launch new initiatives faster. In essence, an integrated enterprise is agile – it can reconfigure processes, scale up, or plug in new capabilities with far less friction. This agility is a competitive advantage in dynamic markets, enabling innovation and expansion (e.g. entering new channels, acquisitions integration, AI adoption) with the confidence that the tech backbone can support it.

Time to Value

Info-Tech’s methodology gets you to an actionable integration strategy in as little as six to eight weeks by leveraging our established frameworks and templates.

A traditional consulting project might take four to six months to produce similar deliverables, often consuming valuable time in extended discovery and analysis.

A do-it-yourself approach without guidance can stretch even longer. Some organizations spend a year debating integration approaches without formalizing a plan.

Direct Cost

For Info-Tech members, developing this strategy is built into your membership (no large extra fees). You gain expert guidance and tools without a six-figure consulting invoice.

In contrast, hiring an external firm for an integration strategy engagement can easily cost US$100,000 to US$250,000.

The DIY route is not free either. It silently costs your staff’s time, pulling your staff away from day-to-day projects for months, often with trial-and-error inefficiencies.

Quality and Best Practices

Our strategy deliverable is grounded in industry best practices and real-world integration success stories, not theory. We incorporate lessons learned from thousands of enterprises (e.g. common failure points to avoid, such as neglecting data governance).

Traditional consulting often delivers a static report for the current use cases. Info-Tech provides a living framework (models, templates, and training for your team), enabling you to execute and adapt the recommended strategy.

Going it alone, companies often miss critical elements (e.g. planning for error handling, aligning integration with data governance), resulting in costly rework later. With Info-Tech, you get a comprehensive, field-tested strategy the first time.

Track integration success

Tracking clear metrics helps monitor the progress and impact of an enterprise application integration strategy.

As the project nears completion:

  1. The number of support tickets related to data sync errors or integration failures should decrease.
  2. The percentage of integrations completed on the first attempt should increase.
  3. The average time to deploy a new integration or resolve an integration issue should decrease.
