How to consolidate vendors without disrupting your business

Reducing complexity without increasing risk

For many organizations, vendor consolidation makes strategic sense—stronger business alignment, reduced complexity, improved cost control and more accountability. Yet one concern often slows progress: “Will consolidation disrupt our business?”

It’s a valid question. When multiple vendors support critical systems and operations, any change can feel high risk.

The reality is that consolidation does not have to be disruptive. With the right approach, it can be structured, phased and controlled, delivering early value while maintaining stability.

We've seen this approach work in practice. Riwal (now part of Boels) set out to simplify the management of its complex IT environment, which included around 40 systems supported by multiple providers. Its focus was not on making rapid changes but on reducing risk.

CGI worked closely with Riwal, taking a phased approach that included learning the environment, documenting critical processes and transitioning services in stages. The result was a smooth transition completed on time and on budget, enabling Riwal to continue business as usual while creating a foundation for greater efficiency and innovation.

Why consolidation efforts often fail

Vendor consolidation initiatives often run into challenges—not because the goal is wrong, but because the approach is incomplete. Key reasons for vendor consolidation failure include:

• Treating consolidation as a procurement exercise: Focusing on cost reduction only overlooks operational dependencies, knowledge transfer and service continuity.
• Underestimating complexity: Vendor ecosystems are deeply interconnected. Without a clear understanding of these dependencies, transitions can create unintended disruption.
• Lack of clear ownership: When responsibility is spread across teams and vendors, decision-making slows and risks increase.
• Insufficient change management: Internal teams and stakeholders need to adapt to new ways of working. Without alignment, even well-designed transitions can stall.

A structured, low-risk approach

Organizations that succeed take a phased and disciplined approach to consolidation, balancing speed with control. Recommended steps include the following:

1. Start with visibility, not action

Before making changes, build a clear picture of your vendor landscape:

• Which vendors support critical operations?
• Where are the dependencies and overlaps?
• What are the cost, risk and performance profiles?
• What is the value of the total ecosystem and is it aligned with business expectations?

This foundation reduces uncertainty and informs better decisions.

2. Prioritize where consolidation creates the most value

Not all areas carry the same level of risk or opportunity. Focus first on:

• Non-critical or highly fragmented services
• Areas with clear redundancy or overlap
• Opportunities for quick wins with minimal disruption

This enables you to build momentum while managing risk.

3. Transition in phases, not all at once

A phased transition reduces disruption and enables continuous learning.

• Define clear transition waves
• Establish governance and escalation pathsThis approach ensures continuity while changes are implemented.

4. Protect knowledge and continuity

One of the biggest risks in consolidation is the loss of institutional knowledge. Mitigate this by:

• Structuring the knowledge transfer early on
• Retaining key expertise during the transitionContinuity should be designed—not assumed.
• Documenting processes and dependencies

Continuity should be designed—not assumed.

5. Embed governance and accountability

Clear governance is critical to managing risk and can be achieved by:

• Defining roles and responsibilities across all stakeholders
• Aligning performance metrics to outcomes
• Ensuring a single point of accountability for delivery
• Managing the ecosystem as a whole and not each vendor individually

This creates clarity and reduces gaps during and after transition.

What success looks like

When vendor consolidation is approached strategically, organizations see benefits early on, without compromising stability. Outcomes include:

• Services continue without disruption during transition
• Delivery becomes more coordinated and predictable, and business aligned
• Costs begin to decrease as redundancy is removed
• Governance improves with clearer accountability

Over time, the organization moves from reactive vendor management to a more stable, integrated operating model.

Turning risk into opportunity

The risk is not in consolidation itself, but in how it is executed. Without change, vendor complexity continues to grow, increasing cost, slowing delivery and introducing new risks.

With a structured approach, consolidation becomes an opportunity to simplify operations, strengthen resilience and improve performance. The key is to approach consolidation deliberately, aligning decisions with business outcomes, operational needs and long-term risk management.
