Investigations

Also known as: Internal Investigation, Fact-Finding Inquiry
Simply put

An investigation is a deliberate, structured process used to uncover facts, confirm details, and reach a well-supported conclusion, often about a specific allegation or incident. In a compliance context, organizations use investigations to examine suspected breaches of laws, regulations, or internal policies. The goal is a thorough, evidence-based understanding of what occurred, rather than assumption or conjecture.

Formal definition

In governance, risk, and compliance settings, an investigation is a methodical inquiry that gathers, examines, and analyzes evidence to establish facts regarding a specific matter, such as an alleged violation of external legal or regulatory requirements or internal policy. It is typically a defined process encompassing scoping, evidence collection, analysis, and documented findings, commonly initiated in response to a report, complaint, alert, or detected anomaly. Investigations are generally management-directed or conducted by designated compliance, legal, or specialized functions and should be distinguished from routine assurance activities such as internal auditing; where an investigation examines potential wrongdoing, it may require heightened attention to independence, confidentiality, evidentiary integrity, and applicable legal privilege. This entry does not address jurisdiction-specific procedural or evidentiary requirements, criminal investigation authority, tooling, or legal advice, all of which vary by context.

Why it matters

Investigations are a central mechanism by which organizations respond to suspected breaches of laws, regulations, or internal policies. When a report, complaint, alert, or detected anomaly suggests possible wrongdoing, a structured investigation allows the organization to establish what actually occurred on the basis of evidence rather than assumption or conjecture. This matters because decisions with significant consequences, such as disciplinary action, remediation, self-reporting to a regulator, or litigation, may follow from the findings, and those decisions are only defensible when grounded in a thorough, well-documented factual record.

Beyond the individual matter at hand, the quality and integrity of an investigation reflect on the credibility of the wider compliance function. Poorly scoped or inconsistently conducted inquiries can undermine confidence in the organization's ability to detect and address misconduct, while investigations that compromise confidentiality, evidentiary integrity, or applicable legal privilege may weaken the organization's position in subsequent proceedings. Because these considerations vary by jurisdiction, sector, and the nature of the alleged conduct, an investigation typically requires careful attention to procedure appropriate to its context.

Investigations also intersect with the organization's broader governance and risk posture. Findings can reveal control weaknesses, cultural issues, or systemic gaps that inform future risk assessment and policy revision. Treating investigations as a disciplined, evidence-based process, rather than an ad hoc reaction, helps ensure that lessons are captured and that the organization can demonstrate it takes reported concerns seriously.

Who it's relevant to

Compliance officers
Compliance functions are frequently responsible for receiving reports and complaints and for initiating or conducting investigations into suspected breaches of laws, regulations, or internal policies. They rely on a consistent, evidence-based process to reach defensible findings and to determine appropriate follow-up.
Legal and regulatory specialists
Legal and specialized functions may direct or support investigations, particularly where potential wrongdoing raises questions of confidentiality, evidentiary integrity, and applicable legal privilege. Their involvement helps ensure the inquiry is handled in a manner appropriate to its legal context, which varies by jurisdiction.
Internal auditors
Auditors need to distinguish investigations from routine assurance activities such as internal auditing. Understanding where an investigation differs, in its management-directed nature and its focus on a specific allegation, helps preserve the independence and objectivity of assurance work while recognizing when a matter warrants a separate investigative process.
Governance professionals and management
Those responsible for governance structures and decision rights have an interest in how investigations are commissioned, resourced, and reported, since findings can reveal control weaknesses or systemic issues that inform risk assessment, policy revision, and broader oversight.

Inside Investigations

Allegation or Trigger
The initiating event, such as a whistleblower report, hotline complaint, audit finding, regulatory inquiry, or management referral, that gives rise to the need to investigate a suspected breach of law, regulation, or internal policy.
Scoping and Planning
The definition of the investigation's objectives, boundaries, timeframe, and resources, including which allegations are in and out of scope, the applicable policies or legal provisions potentially implicated, and the personnel to be involved.
Evidence Collection and Preservation
The identification, gathering, and safeguarding of relevant documents, electronic data, and other materials, commonly with attention to chain of custody so that the integrity of evidence can be demonstrated later.
Interviews
Structured discussions with witnesses, subjects, and other relevant individuals to obtain factual accounts, typically conducted with attention to consistency, documentation, and applicable rights and protections.
Analysis and Findings
The evaluation of collected evidence against the applicable standard to determine whether the allegation is substantiated, unsubstantiated, or unable to be determined, distinguishing established facts from inference.
Reporting
The documentation of the investigation's process, findings, and, where appropriate, recommendations, often directed to management, a governance body, legal counsel, or, depending on jurisdiction and obligation, a regulator.
Remediation and Follow-up
Actions taken in response to findings, which may include disciplinary measures, control enhancements, policy changes, or notifications; these are typically management responsibilities rather than part of the fact-finding itself.

Common questions

Answers to the questions practitioners most commonly ask about Investigations.

Is an investigation the same as an internal audit?
No. An investigation is a targeted, fact-finding inquiry initiated in response to a specific allegation, incident, or suspected breach, whereas internal audit is a planned, independent assurance activity that evaluates the design and operating effectiveness of controls, governance, and risk processes. Investigations are typically reactive and event-driven; audits are typically systematic and cyclical. The two may interact, an audit finding can trigger an investigation, and investigation results may inform audit planning, but they serve different purposes and should not be treated as interchangeable. Keeping them distinct also preserves the independence and objectivity expectations attached to assurance functions.
Does conducting an investigation prove that misconduct occurred?
No. An investigation gathers and evaluates facts to determine whether an allegation can be substantiated, but initiating one does not presuppose or guarantee a finding of wrongdoing. Outcomes may range from substantiated, to unsubstantiated, to inconclusive. Treating the mere existence of an investigation as evidence of guilt misstates its purpose, which is to establish facts objectively so that responsible decision-makers can determine an appropriate response. Presumptions of wrongdoing can also undermine fairness and the reliability of the process.
Who should typically conduct an investigation, and how is independence maintained?
Investigations are commonly assigned to individuals or functions with sufficient objectivity and freedom from conflicts of interest relative to the matter under review, this may include compliance, legal, human resources, internal audit, or external specialists, depending on the nature and severity of the issue and applicable jurisdictional and organizational requirements. Independence is generally supported by separating the investigator from the individuals, units, or controls being examined, and by defining reporting lines so that findings are not filtered by those with a stake in the outcome. Where assurance functions are involved, care is typically taken to preserve their broader independence and objectivity.
How is the scope of an investigation typically defined?
Scope is commonly established at the outset based on the specific allegation, incident, or concern, and may be documented in a terms-of-reference or similar planning artifact. This often addresses the matters to be examined, the period covered, the individuals or processes involved, and the questions the investigation seeks to answer. Scope may be revised as facts emerge, but changes are generally documented to preserve a clear record. A defined scope helps keep the inquiry proportionate and focused, and helps avoid unbounded inquiries that exceed the original concern.
What documentation is generally maintained during an investigation?
Investigations typically maintain a record of the steps taken, evidence gathered, individuals interviewed, and the basis for conclusions reached. Preserving the integrity and traceability of evidence is commonly emphasized, as is documenting the rationale for findings. The level of formality often varies with the severity and potential consequences of the matter and with applicable legal, regulatory, and organizational requirements. This entry does not address specific evidentiary standards, retention periods, or legal privilege considerations, which vary by jurisdiction and matter and may warrant qualified legal input.
How do investigation outcomes typically connect to broader GRC processes?
Findings may inform a range of downstream activities, including disciplinary or corrective action, control remediation, policy revision, updates to risk assessments, and, where applicable, external reporting or disclosure obligations. Because obligations to notify regulators or other parties depend on jurisdiction, sector, and the nature of the matter, whether and how outcomes must be reported externally varies and should be assessed against the specific applicable requirements. Investigation results can also feed lessons-learned processes that strengthen governance, risk, and compliance arrangements over time, though this entry does not cover implementation specifics or tooling.

Common misconceptions

An investigation is essentially the same as an internal audit.
The two differ in purpose and nature. An investigation is generally a reactive, fact-finding response to a specific allegation of misconduct or breach, whereas internal audit is typically a planned, independent assurance activity assessing the design and operation of controls. Conflating them can blur the independence and objectivity expected of assurance functions.
Conducting and closing an investigation resolves the underlying compliance issue.
An investigation establishes facts and reaches findings; it does not by itself remediate root causes. Remediation, disciplinary action, and control improvements are management activities that follow from the findings, and their effectiveness depends on separate follow-up.
Investigation procedures and obligations are uniform across organizations.
Requirements and expectations commonly vary by jurisdiction, industry, and organization size, including obligations around employee rights, data protection, privilege, and regulatory reporting. Practices appropriate in one context may not satisfy obligations in another.

Best practices

Define scope, objectives, and the applicable standard at the outset, and document decisions about what is included and excluded from the investigation.
Preserve evidence promptly and maintain chain of custody so the integrity of documents and data can be demonstrated later.
Maintain the independence and objectivity of those conducting the investigation, separating fact-finding from the management functions responsible for remediation.
Consider involving legal counsel early where privilege, employee rights, data protection, or regulatory reporting obligations may be implicated, recognizing that these vary by jurisdiction.
Distinguish established facts from inference in findings, and characterize allegations as substantiated, unsubstantiated, or indeterminate rather than overstating certainty.
Document the process, findings, and any recommendations consistently, and track remediation and follow-up actions separately from the investigation itself.
