Weekly Investigation Tip - Why Some Investigation Functions Compound and Others Plateau

One of the more interesting patterns I have observed across a career of building and advising corporate investigation functions is that the functions that compound in capability and credibility over a decade-plus look almost identical from the outside to the functions that plateau and then degrade, until you examine the operational discipline underneath. The case types are similar, the headcount is similar, the reporting line and stated independence are similar, and yet the trajectories diverge sharply over the years. The difference, when you trace it carefully, almost always comes down to how the function manages workload, rotation, and the operational discipline of its investigators, none of which appear on the dashboards that leadership typically uses to evaluate function performance.

The investigators on a compounding function are not working harder than the investigators on a plateauing function. They are typically working a workload deliberately designed to sustain high-quality work over years rather than high-volume work over months, and the structural choices that produce that difference are well understood within the profession but not consistently implemented in practice.

The Tip

If you lead an investigations function, or expect to lead one, treat function design as the determining variable in whether your function compounds or plateaus. The structural elements that consistently distinguish compounding functions from plateauing ones, across industries and company sizes, are remarkably consistent and worth implementing intentionally rather than letting them evolve by default:

- Case load management that accounts for matter type and complexity, recognizing that ten complex interview-heavy matters in a quarter represent fundamentally different operational demand than thirty document-driven matters, even when the raw case count looks comparable on a leadership dashboard.

- Reasonable case rotation across investigators when the matter type permits, so that no single team member becomes the de facto specialist for a single matter category and the function preserves both cross-coverage and depth across the whole team.

- A documented transition practice between high-intensity interviews and other work, recognizing that the focus and judgment required for serious interview work benefit from intentional time to write contemporaneous notes, prepare for the next matter, or transition mentally between cases.

- Confidential access to professional resources available to investigators who want them, structured as ordinary professional practice rather than as something tracked or unusual.

- Honest peer conversation, ideally outside the direct management chain, with other investigators who understand the operational demands of the work and can serve as a substantive sounding board on tradecraft questions and difficult judgment calls.

The investigators on your team are the function in a way that other roles are not, since the consistency, judgment, and defensibility of the work depend on practitioners who have accumulated experience that cannot be quickly reconstructed. Functions that design intentionally for sustained high-quality work retain those practitioners and compound. Functions that treat workload management as a question of individual professionalism rather than function design tend to rebuild more often than they build, which is what plateaus look like from the inside.

Your Turn

How does your organization approach the workload and rotation discipline within its investigation function, and do you see your function as compounding in capability year over year, or as resetting more often than it should? Comment below, because the patterns across organizations are worth surfacing for the broader profession.
