How to manage high case volumes in global compliance

Large enterprise organizations face the difficult challenge of managing high case volume in their ethics and compliance programs. With tens of thousands of employees across multiple regions, you can expect a steady flow of reports, ranging from minor HR grievances to serious fraud allegations. A single week might bring dozens of new cases, each with different urgency, complexity, and potential legal exposure. Without a scalable process, teams risk delays, oversights, and even regulatory trouble.

In this post, we’ll explore why high case volumes are challenging, the risks of an overwhelmed case management process, and high-level strategies for managing high case volume ethics and compliance programs effectively.

High volume and complexity are a growing challenge

For large organizations, heavy case volume is business as usual. Companies of around 50,000+ employees tend to see more than 1,000 compliance escalations annually. Smaller companies deal with significantly less. However, with regulation becoming stricter, organizations expanding across borders, and budgets only marginally increasing, almost two-thirds of organizations say they are expecting their caseload to continue rising. High-volume case management is becoming a reality for many compliance teams.

Complexity increases with volume
High volume also means high complexity. A compliance team may simultaneously handle a data privacy breach, a harassment claim, and a corruption investigation. Many reports include multiple allegations, and some span jurisdictions, adding to the challenge. As case volume grows, the old manual ways of handling investigations won't cut it.

Managing complexity at scale requires robust processes
Large organizations must triage and investigate many cases simultaneously, without letting quality slip. By filtering “minor” issues from critical, potentially systemic issues, triage helps ensure serious cases get immediate attention. This is crucial when dozens of new reports may pour in each week. Without an efficient triage and intake process, important red flags could be buried under a pile of lower-risk complaints.

Volume itself can be a double-edged sword
On one hand, a higher number of reports can be a positive sign, as it may indicate a healthy “speak-up” culture where employees trust the reporting process. Indeed, research suggests that more escalations are expected in larger companies and may reflect an effective reporting culture (more people willing to report issues). On the other hand, the sheer volume can overwhelm investigators, leading to backlogs. High case volume is both a byproduct of success (strong engagement) and a potential risk if your program isn’t equipped to handle it.

The risks of an overloaded compliance program

Failing to manage a high case volume carries serious risks for an organization and regulators understand this. For example, the U.S. Department of Justice has emphasized that a hallmark of an effective compliance program is a well-functioning, appropriately funded mechanism for timely and thorough investigations of all allegations. If an organization's case backlog leads to investigations taking too long or being done hastily, it may be seen as a weakness in the compliance program.

Delayed or incomplete investigations
When compliance teams are overloaded with cases, investigations inevitably slow down or remain incomplete. Timely resolution matters and unresolved misconduct can worsen, spread, or escalate into costly legal problems. Regulators expect organizations to have well-funded, well-functioning processes for prompt and thorough investigations. They even recommend tracking metrics like average closure time and outcome consistency.

Oversights and missed warning signs
A heavy case load increases the risk that critical issues will slip through the cracks. Investigators may focus on high-profile cases while overlooking smaller reports that could indicate a broader misconduct trend. Without the capacity to spot patterns (such as repeated harassment complaints in one department) organizations miss opportunities to address issues early. These oversights not only jeopardize compliance but can also lead to financial penalties, lawsuits, and reputational harm.

Strain on teams and loss of trust
Excessive case volume can lead to investigator burnout, inconsistent work quality, and higher turnover, which further reduces capacity. Trust in the ethics and compliance program erodes if employees feel their reports vanish into a “black hole.” Research shows that nearly half of employees don't report misconduct because they don't believe action will be taken.  When cases pile up and responses are slow, these fears become reality. And even worse, whistleblowers may bypass internal channels entirely, going to regulators or the media.

Strategies for managing high case volume in compliance programs

Robust intake and triage for ethics investigations
Create a structured intake process with defined criteria for assessing urgency, risk, and potential legal exposure. The goal is to prioritize high-risk issues for immediate action, while routing lower-risk cases appropriately (for example, a minor HR grievance might be sent to HR to handle).

Invest in corporate compliance software for case tracking
Processes and training can only take you so far when trying to track hundreds of cases via spreadsheets, email threads, or siloed systems. A centralized case management system is essential for large organizations. While human judgment is still crucial, automation and analytics can assist by clustering similar reports or highlighting anomalies that deserve attention.

Scaling investigation teams to meet demand
An overstretched team cannot properly investigate everything. Management should regularly review case volumes and scale the compliance investigations team accordingly. If adding full-time staff isn’t feasible, consider creative resourcing. Temporarily bring in trained contractors or cross-train other personnel (like HR, legal, internal audit) to assist in investigations when needed.

Standardized compliance investigation procedures
When dealing with high volume, consistency is key. Develop a clear, step-by-step playbook for investigations. Standard templates and checklists save time and ensure nothing important is overlooked. Every case should follow a defined workflow, with documented steps for intake, triage, investigation, resolution, and close-out. By standardizing these processes, even a large team can operate in sync and maintain quality, and it also allows for easier onboarding.

Turning volume into value

High case volume doesn’t have to be a liability. With the right people, processes, and technology, compliance teams can manage heavy caseload to spot risks earlier, improve culture, and show regulators they can maintain program integrity under pressure.

A scalable, data-driven approach helps transform managing high case volume ethics and compliance programs from a reactive burden into a proactive strength.
