Who Should Be Entrusted with IT Integration?

Introduction

When IT fragmentation becomes apparent, questions inevitably arise: “Who should integrate the company’s IT?” “Should it be the IT department, the CIO, or the CDO?” “Should we entrust it to a strong leader?” Many companies tend to approach this question with the premise that it can be solved by delegating it to “someone.” This article re-examines the question from the ground up: Is IT integration even a task that *can* be delegated? We will structurally clarify who should bear the responsibility and who cannot.

IT Integration is About “Decisions,” Not “Coordination”

First, we need to confirm the premise. What IT integration means is not about consolidating systems, connecting data, or standardizing rules. Its essence lies in deciding what to discard and what to keep among multiple options. Specifically, it involves judgments such as which department’s IT to prioritize, which investments to halt, and whether to focus on short-term results or mid-to-long-term structural changes. This is not coordination; it is clear-cut decision-making (management judgment).

Why It Cannot Be Entrusted to the IT Department

The IT department (Information Systems) is the entity that knows the company’s IT landscape best. However, that is a separate issue from whether they can be entrusted with IT integration. Typically, the IT department is not granted the authority to halt departmental IT initiatives, reverse investment decisions, or change business priorities. Entrusting integration under these conditions creates a structure of “having responsibility but no authority to decide,” and IT investment optimization will not progress.

Why Entrusting It to a CIO or CDO Also Fails to Solve the Problem

What about a CIO (Chief Information Officer) or CDO (Chief Data Officer), then? As we have seen, the CIO role is often not designed to act as a proxy for management decisions, and the CDO frequently lacks the authority to determine company-wide priorities. Simply creating a title does not equate to delegating the management judgment itself. It is crucial to understand that a job title is not a substitute for decision-making.

Only “Management” Can Bear the Responsibility for IT Integration

Based on the discussion so far, there is only one answer. The only entity that can bear the responsibility for IT integration is management itself. This is because all the judgments required for IT integration are inseparable from business strategy, investment allocation, and organizational design. The only entity capable of making these decisions simultaneously is management (the management team/top executives). This is one of the core system strategies for successfully driving DX (Digital Transformation).

This Does Not Mean Management Must “Do Everything”

It is important not to misunderstand: this is not about management micromanaging every detail of IT. What management must take on is defining the purpose of integration, the criteria for decisions, and the resolve to make trade-offs. On that foundation, execution and design should be delegated to the following experts:

• IT Department (Information Systems)
• CIO (Chief Information Officer)
• CTO (Chief Technology Officer)

The moment this sequence—”management owns the decisions, experts handle the execution”—is reversed, the integration effort will fail.

Not “Delegate,” But “Take Ownership”

The most critical perspective in IT integration is not *who* to delegate to, but *what* we (management) must take ownership of. Unless it is clearly defined which decisions management will own and from which point experts will be entrusted, integration will not advance. Fragmentation will be perpetuated, and a cycle of someone burning out will repeat.

Conclusion

The answer to the question, “Who should be entrusted with IT integration?” is: “It should not be entrusted to *anyone*.” To be precise, the judgments that management should own must not be pushed onto someone else. IT integration is the process by which management redesigns its decision-making structure, and as a result, IT becomes integrated. Unless this order is maintained, IT integration will remain forever incomplete. The responsible entity, from start to finish, is management. Implementing SaaS or reorganizing the IT organization—advancing these initiatives in line with this fundamental principle is the shortcut to realizing a true IT strategy.
