Why It Is So Hard To Manage External Spend Well

Every executive agrees that managing spend matters. Yet few believe their organization does it well.
Budgets are approved. Policies are in place and procurement teams work tirelessly, but results often fall short. Savings targets are met one quarter and eroded the next. Supplier relationships drift. Value slips quietly through the cracks.
At FTI Consulting, we see this pattern across industries. The issue is rarely a lack of process or technology. More often, organizations underestimate that spend management is fundamentally human. People make decisions in ways that are messy, inconsistent and influenced by incentives, habits and emotion. The result is lost value across the enterprise.
The Invisible Complexity of Spend Decisions
External spend appears straightforward on paper: an organization buys goods or services to achieve its goals. In practice, it involves hundreds of daily decisions across functions, geographies and reporting lines. Each decision carries context, trade-offs and a different interpretation of value.
A marketing leader renews an agency because the team trusts them. An operations leader changes suppliers to improve lead times. A project manager expands scope to maintain momentum. None of these choices appear significant in isolation, but together they determine how effectively the organization converts spend into business value.
This complexity often remains invisible until it is mapped. Once organizations do so, a familiar pattern emerges: decisions are fragmented, ownership is unclear and governance is uneven. In many organizations, the system produces exactly what it was designed to produce, which is to say it was never truly designed as an enterprise system.
Why Traditional Approaches Fall Short
Many organizations respond to spend inefficiency by adding controls. They introduce new approval workflows, mandate preferred suppliers or tighten procurement policies. These measures can improve compliance, but they do not necessarily improve outcomes or value creation.
At FTI Consulting, we emphasize a simple distinction: controls manage behavior. Governance shapes intent.
Traditional spend frameworks assume that if people follow the right process, results will improve. In reality, purchasing decisions are rarely made on process logic alone. People respond to incentives, culture and convenience. They optimize for local objectives, such as protecting timelines, satisfying stakeholders and preserving flexibility, rather than maximizing enterprise value.
We often see this in decentralized environments where business units purchase similar services from different suppliers, often at different rates and with inconsistent terms. From the perspective of each leader, the decision is rational. From an enterprise perspective, the result is fragmented demand, duplicated effort and reduced leverage.
When leaders say, “Central sourcing slows us down,” they are often revealing something more important than resistance to procurement. They are describing a system that rewards speed over stewardship. That is a governance issue, not simply a sourcing issue.
The Behavioral Side of Spend
Spend management is often treated as an operational challenge, but in our experience it is equally a behavioral one.
Several common biases shape spending behavior in ways policies alone cannot address:
- Familiarity bias: preferring known suppliers even when stronger options exist
- Endowment effect: overvaluing incumbent contracts because they feel earned
- Loss aversion: avoiding changes to spending decisions for fear of disrupting relationships or delivery
These behaviors are not signs of poor leadership. They are normal human tendencies. They persist even in organizations with strong systems and capable teams. Technology can improve visibility and track spend, but it cannot by itself change how people evaluate trade-offs.
For that reason, influence matters as much as enforcement. Organizations that manage spend well do not rely solely on tighter rules. They design environments that make better decisions easier through transparency, clearer incentives, defined decision rights and trust.
The Governance Gap
Governance is often misunderstood as bureaucracy or a checklist of approvals and signoffs. At FTI Consulting, we view it differently: governance is a leadership system that defines who decides what, how and why.
The governance gap emerges when spend accountability is split across functions. Business units own budgets. Procurement owns process. Finance owns reporting. Yet no one consistently owns the central question: does this spend advance our strategic priorities and create value?
In well-governed organizations, that question is built into the decision process. Spend governance connects the how of procurement to the why of strategy. It gives leaders visibility into trade-offs before costs become commitments.
Without that connection, even high-performing teams can make rational local decisions that produce irrational enterprise outcomes. The whole becomes less than the sum of its parts.
Why It Is Hard and Why It Matters
Managing external spend effectively is difficult because it requires alignment across three dimensions that rarely move in sync:
- Human judgment
- Organizational structure
- Strategic intent
Most organizations can optimize two of these at once, but rarely all three. They may have strong strategy and efficient processes but weak ownership, or clear accountability but conflicting incentives. Sustainable spend performance requires integrating all three, which is why spend governance demands executive attention.
This is also where the opportunity lies.
When leaders treat spend as a behavioral and governance system, not simply a cost category, they unlock more than savings. They improve decision quality, strengthen accountability and create a clearer link between investment and enterprise value.
Case Study
Spend governance should not be a list of rules that limits employees’ ability to complete their work. Instead, it should help teams operate more efficiently while driving measurable value and savings. FTI Consulting has delivered governance solutions that both improve operations and generate meaningful financial results.
Recently, FTI Consulting helped an international technology manufacturer optimize its service technician automotive fleet. The objective was to enable technicians to work more efficiently while reducing costs.
The client managed more than 2,000 technicians across more than 200 different titles. Each technician had different needs from their vehicle. Some required space for large replacement parts while others needed smaller vehicles to navigate dense city environments.
As a result, the organization defaulted to the simplest solution: allowing technicians to select their own vehicles. Over time, this created a fleet that was excessive in both functionality and cost.
FTI Consulting approached the problem with a clear objective: deliver savings while ensuring technicians could still perform their service calls effectively.
Our team segmented the more than 200 job titles into five technician categories based on experience, service type and operational needs.
We then reviewed more than 15 vehicle models historically used across the fleet, analyzing total cost of ownership including fuel economy, maintenance, repair and lifespan alongside operational requirements such as storage capacity, workspace and drivetrain.
Finally, we developed a governance framework that assigned vehicles based on role, required spare parts, mileage and geography. Supervisors could easily match technicians with vehicles that met operational needs while remaining cost-effective.
However, assigning vehicles alone would not succeed. Technician buy-in was essential.
During a training session, FTI Consulting hosted a hands-on vehicle workshop with a representative group of technicians. The leasing company brought multiple vehicle types including trucks, vans and crossovers along with potential modifications. Technicians evaluated each option and provided feedback on what they needed to perform their jobs effectively.
The result was a solution that balanced operational performance with cost discipline. FTI Consulting delivered $3 million in savings on $30 million of annual fleet spend while enabling technicians to complete service calls effectively.
The Executive Takeaway
The challenge of managing external spend is not a flaw in the organization. It is a signal. It reflects how decisions are made, how incentives are structured and how strategy is translated into action.
If spend is misaligned, strategy is likely misaligned. If governance is weak, accountability is often weak as well. The answer is not simply more control. It is stronger leadership and better system design.
The most effective executives stop asking, “Why is this so hard?” and instead ask, “What are we doing to make it easier for our teams to make better decisions?”
At FTI Consulting, we believe that is the core of effective spend governance: designing a governance system and operating model that consistently turns strategic intent into measurable value creation and growth.
