Corporate Investigations

When Assessment Becomes Investigation

David P. Frizell, Jr., CFE · September 1, 2026

When a serious workplace allegation surfaces, leadership has an immediate responsibility to understand enough about the issue to decide what should happen next. But there is an important distinction between conducting a preliminary assessment and unintentionally beginning the investigation.

When a client first calls me, I rarely begin by asking who they think is responsible. My first questions are usually more basic: How did you learn of the problem? Who else knows? What specifically has been alleged, and are particular people identified? What steps have already been taken?

Those questions are not intended to solve the case. They help leadership understand the nature and source of the allegation, assess its seriousness, and determine the appropriate next steps.

A preliminary assessment is valuable. A pre-investigation can be damaging.

The Purpose of a Preliminary Assessment

A preliminary assessment should gather enough information to allow leadership to make an informed decision without unnecessarily compromising what may follow.

That usually means understanding how the concern surfaced, the specific nature of the allegation, who already knows about it, whether particular employees or third parties have been identified, what evidence may exist, and what actions have already been taken. It does not mean leadership must immediately determine whether the allegation is true. At this stage, the more important question is what process and resources are appropriate for establishing the facts.

Not every workplace problem requires an investigation. Poor performance, habitual tardiness, dress-code issues, and other routine management matters may appropriately remain management or Human Resources issues. Allegations involving fraud, theft, serious compliance or ethics violations, insider threats, or possible criminal conduct may require a different response.

When Assessment Quietly Becomes Investigation

Problems arise when well-intentioned managers begin informally questioning employees, sharing available evidence, discussing suspicions, or otherwise trying to determine what happened before an investigative strategy has been established.

Witness recollections can be influenced. Confidentiality can be compromised. Evidence can change or disappear. And the people under scrutiny may learn enough about the allegations and evidence to make establishing the facts considerably more difficult.

The line is not always obvious. Asking who reported the concern and what was alleged may be necessary to understand the problem. Repeatedly questioning potential witnesses about what they saw or confronting a suspected employee with the evidence begins moving into investigative activity.

The objective is not inactivity. It is disciplined transition.

Specialized Work Requires Specialized Skills

Years ago, I worked closely with a Human Resources professional on a number of employee interviews involving various allegations. After observing and participating with me over time, she understandably became comfortable with the truth-seeking interview process.

When a new allegation arose involving two employees, she decided to conduct the interviews herself. She interviewed each employee several times. When neither acknowledged wrongdoing, she called me to see whether I could interview them and resolve the matter.

I declined.

By then, both employees were firmly committed to their denials, and the limited evidence had already been shared with them. Whatever opportunity may initially have existed for a different truth-seeking interview strategy had largely passed.

The lesson was not that Human Resources should not be involved in investigations. HR professionals possess expertise and responsibilities that are essential in many workplace matters. I am not a professional Human Resources executive, and I would not presume that observing HR professionals perform their work qualified me to perform all of their duties.

The same principle applies to investigative interviewing.

One of the most useful lessons for leaders is: Don't be embarrassed to be good at something without thinking you have to be good at everything.

Good leadership recognizes professional specialization and puts the right expertise around the problem.

Leadership Remains Responsible

The transition from assessment to investigation does not mean leadership's role ends.

Quite the opposite.

Leadership, Legal, Human Resources, Security, Compliance, management, internal investigators, and outside specialists may all have important roles. The difference is that those roles should now be coordinated around a deliberate strategy designed to establish the facts while protecting the organization and treating everyone involved fairly.

Leadership may also need to make decisions that cannot wait for the investigation to conclude: protecting employees, preserving evidence, addressing an immediate security concern, satisfying legal or regulatory obligations, or determining whether temporary workplace measures are necessary.

The investigative process should support those responsibilities, not displace them.

Not Every Matter Requires an Outside Investigator

I have advised clients many times not to hire me or Frizell Group.

Sometimes the organization already has the appropriate internal expertise and independence. Sometimes the allegation does not justify a formal investigation. Sometimes the client's needs are better suited to another specialty.

In one type of situation, for example, investigating a cash loss may have little practical value if dozens of people had uncontrolled access to the funds, audits occurred only monthly, and there were no cameras, point-of-sale controls, or other means of determining responsibility. The more useful response may be to identify the control failures and harden the target against future theft.

The purpose of the preliminary assessment is therefore not to justify an investigation. It is to help leadership determine the most responsible next step.

From Assessment to Deliberate Investigation

A sound preliminary assessment ends when leadership has enough reliable information to determine what should happen next without unnecessarily expanding the circle of knowledge or compromising potential witnesses, evidence, or subjects.

At that point, the organization should move deliberately. Determine who should lead the investigation. Establish the roles of the necessary internal functions and outside specialists. Preserve relevant evidence. Decide who needs to know. Develop an investigative strategy before substantive interviews begin.

That transition is not where leadership involvement ends. It is where leadership ensures that the right people, process, and strategy are in place to determine the facts. Good leadership does not step aside when an investigation begins.

It recognizes when assessment should become investigation—and makes sure the organization is prepared to make that transition well.

Key Takeaways

  • A preliminary assessment should gather enough information to determine the appropriate next step without prematurely trying to solve the matter.
  • Leadership should distinguish necessary early assessment from substantive questioning and other investigative activity.
  • Well-intentioned pre-investigation can influence witnesses, expose evidence, alert subjects, and make later fact-finding more difficult.
  • Professional specialization matters; Legal, HR, Security, Compliance, management, and investigators each bring different expertise.
  • Not every workplace concern requires a formal investigation, and not every investigation requires an outside investigator.
  • Leadership remains responsible throughout the process for ensuring the right people, process, strategy, and oversight are in place.
