- Corporate investigative functions face challenges from rapid technological advances, regulatory change, and increasing organizational complexity. Even the strongest functions may need periodic recalibration to manage the pace of change.
- A fit-for-purpose operating model may require a variety of approaches (insourced, outsourced, co-sourced) instead of a single model. For example, different delivery models may be appropriate for routine employee matters, specialist investigations, demand surges, cross-border cases, and board- or regulator-sensitive matters.
- The right model will depend on many factors unique to your organization such as demand volatility, investigation type, regulatory scrutiny, speed and quality, organizational complexity, technical capabilities, specialized expertise, and need for independence. A framework for assessing these factors can help you build an agile, scalable investigations function that’s future-ready.
Corporate investigative functions are under increasing pressure to change. Rapid adoption of AI, variable regulatory expectations, and expanding operational complexity are reshaping how organizations investigate allegations of misconduct. At the same time, many investigative teams are expected to do more with constrained budgets, lean staffing models, and legacy technology and processes that weren’t designed for today’s risk environment. Even the most sophisticated functions have room to improve.
The first step for many organizations is determining what that change should look like. Do we build out our internal investigative capabilities and technology? How can we best triage new matters to make the right decisions? Should we outsource parts of our investigations function to specialized third parties with scalable resources and deep technical expertise? Or does a hybrid co-sourcing model offer the right balance of institutional knowledge, flexibility, and operational efficiency?
There’s no universal answer. Company culture, geographic footprint, resourcing, and organizational complexity all influence the optimal model for tackling internal investigations. Demand volatility and investigation type (HR matters, financial misconduct, conflicts of interest, customer-facing fraud, regulatory inquiries) are key factors in resourcing decisions. Increasingly, investigations teams must also evaluate the maturity of their technology environment, access to specialized expertise, and the degree of independence required for sensitive or regulator-facing matters.
Don’t try to apply the same approach to every investigative need. A mature operating model may retain internal ownership of governance and routine matters, use co-sourced capacity for fluctuating volumes, engage specialists for technical matters, and establish independent external leadership for particularly sensitive investigations.
Should you recalibrate your operating model?
Organizations rarely fit neatly into a single model. Most investigations functions operate along a continuum: insourced, co-sourced, or outsourced.
These three approaches aren’t mutually exclusive, enterprise-wide choices. They can coexist while supporting different matters, priorities, or stages in the investigation life cycle. In all cases, the organization’s internal leaders retain accountability and oversight, even when external resources perform parts of the work.
While each model offers distinct advantages, the choice usually comes down to which one is best suited to the realities and needs of a particular organization. In our experience, this decision requires an assessment of many factors that fall under three broad categories: institutional context, case complexity, and external sensitivity.
Institutional context (culture, conditions, and capabilities). The most successful investigations operating models align with the company’s culture and operating environment.
Some organizations place high value on institutional knowledge and believe investigations should be conducted primarily by people who understand the company’s history, leadership dynamics, and ways of working. In that environment, a heavily outsourced model may face resistance regardless of its economic or operational merits. But other organizations may be more accustomed to using external specialists and may view an independent third party as a valuable source of objectivity and expertise. They may even consider the retention of internal resources a constraint on the program’s long-term effectiveness.
Context also manifests itself in more practical ways. Global organizations must consider how investigations are conducted across different regions, languages, and employment frameworks. In some jurisdictions, labor laws, works councils, unions, or other employee representative bodies may play a formal role in the process. In others, a more direct approach to interviews and fact-finding may be culturally acceptable or even expected. Understanding these dynamics is essential.
Companies with diverse lines of business may face investigative challenges that vary greatly from one business unit to another. An industrial products manufacturer may encounter investigations primarily involving supply chains, inventory, safety incidents, or asset misuse, while its consulting or engineering services division may see more investigations related to professional conduct, client interactions, billing practices, or intellectual property.
These differences affect the skills required, the investigative approach, the types of evidence collected, and the tech platforms involved. Internal teams need to be current on what’s happening both within their organization and across their industry to understand what matters or emerging risk patterns may be occurring. As business complexity increases, organizations may find more value in operating models that provide broader access to specialized expertise and capabilities, as well as greater flexibility.
Tech maturity is another critical factor. Investigations teams with advanced internal analytics, case management platforms, and AI-enabled workflows may be capable of handling greater caseloads and complexity while driving better insights, improved quality, faster case resolution, and lower costs. Others may need external providers for specialized tools and capabilities.
Case complexity (investigation types and volume). Not all investigations are equal. Some companies manage a relatively steady stream of similar matters, allowing them to build standardized processes and dedicated internal teams. Others face variable demand, with periods of routine activity punctuated by surges in allegations, acquisitions, and regulatory inquiries.
Case complexity also varies by subject matter. Workplace misconduct, fraud, corruption, cybersecurity, customer-facing investigations, and regulatory matters each require their own skill sets and expertise. Financial institutions often have large case volumes and typically have specialized teams focused on narrow, regulation-driven tasks, whereas other companies may have more generalist investigative functions. You’ll need to evaluate whether your internal capabilities can address the full range of cases you encounter or whether you need outside help for certain matters.
Language requirements, jurisdiction-specific legal obligations, and investigative independence add further complexity. Your company may be fully capable of handling routine investigations internally while requiring outside support for cross-border matters, highly technical investigations, or situations requiring an independent fact finder.
External sensitivity (governance and stakeholder scrutiny). Possibly the most salient, and often least predictable, consideration is the degree of external scrutiny an investigation may face.
Most investigations never become public, but you can’t always predict which matters will attract the attention of regulators, shareholders, the media, or public opinion. A routine allegation can quickly evolve into a regulatory inquiry. An employee complaint can become a headline. An isolated incident can trigger shareholder concerns about governance and oversight.
Organizations operating in heavily regulated industries may face elevated scrutiny as a matter of course, making independence, documentation, and defensibility critical factors. Even in less regulated sectors, companies should consider how they’d respond if a matter became public. Would stakeholders view your process as sufficiently independent? Would your company be able to demonstrate appropriate expertise, objectivity, and governance?
For particularly sensitive matters, a properly mandated external team can provide a rapid “credibility reset” when stakeholders question the objectivity of an internal process. However, independence doesn’t necessarily require outsourcing. An external provider isn’t automatically independent, just as an internal team isn’t automatically conflicted. Independence is created through mandate and governance, not the identity of the investigator.
Taken together, these considerations suggest that the most effective investigations functions are rarely built around a rigid, one-size-fits-all model. Instead, they’re designed to balance institutional knowledge, specialized expertise, scalability, and independence in a way that reflects the organization’s unique culture, investigative demands, and risk environment. Consider the following scenario:
A multinational organization had a capable internal investigations team but experienced periodic case surges, inconsistent regional documentation, and limited visibility into recurring themes. Rather than outsource the entire function, the company retained internal governance and routine employee matters, introduced co-sourced capacity for volume spikes, established specialist support for complex fraud and cross-border matters, and implemented common methodology and portfolio analytics. The result: faster response during peak periods, improved consistency and defensibility, quicker resolution of complex matters, and stronger intelligence and reporting, all while preserving critical internal knowledge.
Broader themes driving the choice of model
While every organization is unique, several recurring themes shape how companies evaluate their investigations operating models.
Cost takeout is an incomplete measure of value. Choosing an operating model based on cost alone can be misguided. Assessing ROI requires a nuanced, holistic view of the full value a given approach can deliver, one that goes beyond traditional metrics such as hours saved and headcount reduced.
A fixed, “always on” in-house model may create value where demand is stable, institutional knowledge is essential, and specialist capability is sustainable. But its true price tag may include other costs such as maintaining capacity for occasional surges, investing in specialized skills and technology, carrying backlogs when demand exceeds staffing, and accepting the risk of inconsistent quality or delayed remediation.
Conversely, external support may create value where demand is unpredictable or expertise is needed intermittently. But outsourced delivery can also become inefficient. You should consider what might be lost or made more difficult when work moves outside the organization, things like continuity of relationships, institutional knowledge, internal development of investigative talent, day-to-day oversight, and the ability to respond without relying on a provider’s availability. External support can also become expensive if scope is unclear, matters are repeatedly handed off, or the organization pays for senior expertise without a disciplined way to use it.
The strongest approach is usually deliberate rather than ideological. That means retaining capabilities central to your organization’s identity, governance, and long-term resilience; using external support where it provides genuine advantages in scale, independence, specialist expertise, technology, or speed; and revisiting the balance periodically.
Case portfolio dictates skills requirements. Not all investigations require the same capabilities, workflows, or personnel.
- HR and employment matters usually demand strong interviewing and employee-relations skills.
- Financial fraud investigations require forensic accounting, data analytics, and controls expertise.
- Misuse of assets cases typically need security, legal, and operational knowledge.
- Customer-facing fraud operations can resemble high-volume managed services environments, meaning they may call for scalable operational processes, analytics, and surge handling.
- Regulatory or board-sensitive matters may require a high degree of independence and specialized legal coordination, meaning external counsel and/or forensics specialists.
As organizations face a broader range of investigative demands, many turn to hybrid or co-sourced models because no single internal team can efficiently maintain deep expertise across all domains.
Preserving institutional capability is imperative. Even where organizations make extensive use of outside providers, they generally need to retain meaningful internal capability. Effective investigations often depend on an understanding of the organization’s history, culture, business operations, stakeholder relationships, prior matters, and internal decision-making processes. That context can be difficult to recreate matter-by-matter and can materially affect how allegations are assessed, investigations are scoped, and findings are interpreted.
For that reason, even highly outsourced or co-sourced models typically require strong internal ownership. Legal, compliance, or investigations leaders should retain responsibility for governance, stakeholder management, escalation, disposition, remediation, provider oversight, and coordination of access to information and internal resources. External support can supplement that capability, but it doesn’t eliminate the need for informed internal judgment and accountability.
The same holds true over a longer time horizon. An operating model that relies too heavily on external resources or automation may inadvertently weaken an organization’s investigative talent pipeline. Fewer opportunities to conduct interviews, assess evidence, exercise judgment, and manage matters can eventually create gaps in succession, leadership, and the organization’s ability to oversee complex investigations effectively.
That means you should consider not only what work can be performed externally or automated, but also which capabilities you need to preserve internally for long-term resilience. The strongest models deliberately retain the knowledge, judgment, relationships, and leadership capacity that are strategically important to the organization while using external specialists, technology, and flexible capacity where they provide a genuine advantage.
Technology means more than just efficiency. While AI-enabled tools can help accelerate investigation timelines and reduce costs, more compelling opportunities lie elsewhere. Technology can drive improved consistency and value across the investigation life cycle, from intake and triage, planning, data collection, evidence review, interview preparation, management reporting, quality control, and remediation. It can also transform investigation data into enterprise risk intelligence, helping your organization make better decisions, identify risks, and mitigate those risks before they have wide-ranging impact.
But reliance on technology has risks. Without proper supervision and guardrails, AI-enabled solutions can present issues in terms of accuracy, explainability, bias, defensibility, privilege, data governance, and access controls, among other concerns. Managing these risks requires preserving human oversight and judgment while embedding responsible AI practices throughout the investigation life cycle.
A framework for resilience
No single model will be right for every organization, or even for every type of investigation within the same organization. The more useful question is whether your current model provides the right combination of capability, capacity, institutional knowledge, technology, governance, and independence for the risks your company faces today and expects in the future.
That assessment should begin with a practical look at how your investigations function performs across several dimensions. Consider where the current model is working well, where gaps or constraints are emerging, and which capabilities are strategically important to retain internally. Identify where external support could provide meaningful advantages.
- Can our model scale without permanent excess capacity?
- Do we have the right expertise for matters we’re likely to face?
- Are standards, processes, and documentation consistent across teams and regions?
- Can we identify patterns across investigations?
- Would our governance and independence withstand regulatory or board scrutiny?
- Are we developing the next generation of investigative leaders?
- Do we know the true cost of our current model?
- Could an external party help restore confidence in particularly sensitive matters?
An illustrative decision matrix
Investigative need |
Potentially appropriate model* |
Why |
| Routine, recurring employee matters | Internal delivery | Preserves context, relationships, and internal capability where demand and skills are predictable |
| High-volume or seasonal demand | Co-sourced or managed capacity | Provides scalability without permanently staffing for peak volumes |
| Highly technical matters such as cyber, data analytics, or complex fraud | Specialist external support | Brings expertise that may be difficult or inefficient to maintain internally |
| Board-, executive-, or regulator-sensitive matters | Independent external leadership or support | Strengthens credibility, objectivity, and defensibility where perception risk is high |
| Cross-border or multi-jurisdictional matters | Hybrid model | Combines internal knowledge of the organization with local business environment experience |
| Program governance, methodology, and quality assurance | Internal ownership with external benchmarking or advisory support | Keeps accountability inside the organization while providing an independent view of consistency and leading practice |
| Portfolio analytics and emerging-risk insight | Co-sourced technology and analytics capability | Helps connect patterns across matters while retaining appropriate human oversight and governance |
*These are not fixed prescriptions. The appropriate model depends on the organization’s facts, and the same matter may require different support at different stages of its life cycle.
Looking ahead
The goal is to design a resilient portfolio of capabilities with clear accountability, appropriate independence, access to specialist expertise, effective use of technology, and the flexibility to adapt as risks and expectations evolve. Even strong functions benefit from periodically benchmarking their model, identifying gaps, and recalibrating the balance between internal capability and external support.
The most effective investigations operating model isn’t necessarily the one that works best today. More likely, it’s a combination of approaches that can adapt as your organization evolves.
As you evaluate different approaches, consider not only your current operating environment but also what you anticipate in the coming years. Regulatory expectations, workforce composition, tech capabilities, AI adoption, business complexity, and investigation volumes are all shifting rapidly. A model that was fit-for-purpose by historical standards may prove inadequate, or too costly, tomorrow.
By evaluating organizational context, case complexity, and external sensitivity through both a current-state and future-state lens, you can build an investigations function that’s resilient, adaptable, and ready for what lies ahead.
