Beyond Multisourcing: Managing Multiprovider Engagements

The struggle to balance single- and multisourcing decisions is pervasive. Because service engagement decisions are fragmented across the organization and made at the portfolio level — not the enterprise level — companies are constantly at odds. IT is often focused on consolidation while business functions establish new relationships. This creates a strategic disconnect. We need a new management model that can unify these efforts and optimize our provider ecosystem for maximum business value rather than just chasing a single-vendor ideal.

The current wind is blowing in the direction of consolidation, but consolidation is a means, not an end. While many organizations are being driven by consolidation, many enterprises approach it as a reactive, cost-cutting measure. The true challenge isn’t just reducing the number of partners but rather establishing a strategic framework that informs these decisions. In one case, a Forrester client has consolidated more than a dozen active global systems integrators (GSI) engagements into a single uber-relationship with a single service provider. While this simplified their portfolio, it also led to a significant pitfall: They were pressured into an engagement that was logical on paper but not the best fit in context. This “single uber-relationship” is unusual. GSIs are pursuing consolidation opportunities as a discrete category of service, but a single partner left standing is a risky goal. We discuss the dynamics of this shift in the recent report, Stop Struggling With Single Vs. Multiple Service Provider Decisions.

The Expanding AI Ecosystem Requires A New Approach To Service Integration

A big change is coming. While the goal may be to consolidate, the reality is that a multiprovider ecosystem is here to stay. Multiple players are part of the expanding AI ecosystem, including global system integrators, hyperscalers, resellers, and telcos but also nontraditional players such as model builders and chipmakers. The challenges are integration and coordination. The process to create a more streamlined, effective, and strategically aligned partner ecosystem is the best outcome and not consolidation, which is the end goal that some of these players may play a highly critical role in solutioning but perhaps only for limited periods of time. The introduction of new types of entities like model builders also raises the question of familiarity: How will they behave as commercial partners?

This brings us to a discussion about service integration and management, traditionally referred to as SIAM. SIAM has been used primarily as a means to knit different service “towers” together using mechanisms such as the operating level agreement from ITIL. Numerous suppliers, including Accenture, Capgemini, Deloitte, HCLTech, Kyndryl, and Scopism, are working on reinvigorating SIAM to fit the emerging requirements: Instead of getting mired in the operational “incident, problem, change” loop, they’re using SIAM as a way to pursue business advantage by informing service provider engagement decisions. It will not be easy to make this shift on an industrywide basis, but forward-thinking enterprises can use it as a means to enforce simplification in enterprise portfolios and support business priorities through optimal partner selection.

SIAM is sometimes derided by ITIL skeptics, who are prepared to throw out the SIAM baby with the ITIL bathwater. They have a point given SIAM’s mixed record as a commercial proposition. But the new agentic AI ecosystem will require a new approach to service integration, as well as making explicit preconditions and qualifications for participation. The advent of agentic AI is also likely to accelerate the shift from horizontal to more vertical outsourcing models, in which case multiple GSIs are likely to coexist as suppliers of agentic solutions (this is less so for horizontal services such as applications management).
