Human Performance Tools Every Procedure Program Should Use

What human performance tools should every procedure program use?

Every procedure program should support eight core human performance tools: pre-job briefings, self-checking (STAR), three-way communication, peer checking, independent verification, place-keeping, questioning attitude, and procedure use and adherence. These are practical, repeatable techniques that reduce the chance of human error during high-consequence work.

The tools come from decades of human performance research in nuclear power, aviation, and other high-reliability industries. The U.S. Department of Energy's Human Performance Improvement Handbook (DOE-HDBK-1028-2009) collects many of them in one place. They share one premise: people will make mistakes, so the goal is to catch an error before it reaches the work.

The connection most organizations miss is that these tools and the procedures are not separate systems. A procedure written without the tools in mind quietly works against them. A procedure written to support them makes them second nature.

What are the core human performance tools?

Pre-job briefing. Before the work starts, the team reviews the task, the critical steps, the hazards, and what could go wrong. A briefing is only as good as what it reviews, so the procedure should make critical steps and their consequences easy to find.

Self-checking (STAR: Stop, Think, Act, Review). Before an action, especially on a critical step, the worker pauses, confirms the right component and the right action, performs it, and verifies the result. It is the most broadly applicable error-reduction technique. Procedures support it by naming the exact component and the expected result, so there is something concrete to check against.

Three-way communication. The sender states an instruction, the receiver repeats it back, and the sender confirms it. This sharply reduces misheard and misunderstood instructions. Procedures support it by writing communication steps that expect a repeat-back, using exact component names and values.

Peer checking. A qualified coworker observes the performer just before an action to confirm it is the right component and the right action. It is less formal than independent verification and well suited to catching slips. Procedures support it by marking the steps where a peer check is expected.

Independent verification. A second qualified person confirms a component's condition separately from the person who performed the action, without relying on their word. Procedures support it by identifying exactly which steps require it and providing a separate sign-off.

Place-keeping. Marking progress through a procedure so no step is skipped or repeated. This is almost entirely a design issue: the document either provides usable place-keeping aids or it doesn't. Inconsistent place-keeping methods are one of the 18 error traps we teach.

Questioning attitude. Pausing to resolve doubt when something doesn't match expectations, rather than pressing on. Procedures support it by giving clear hold points and explicit conditional steps, so the worker knows when to stop and what to do next.

Procedure use and adherence. Using the procedure in hand, as written, rather than working from memory. Many programs assign each procedure a use level, such as continuous use, reference use, or information use, so workers know how closely to follow it. This tool ties the others together, and it depends on procedures being usable enough that following them as written is practical.

How does procedure design affect human performance tools?

Every one of these tools is either enabled or undermined by how the procedure is written. A human performance tool is only as strong as the procedure underneath it.

Consider procedure adherence. You can train it, expect it, and measure it. If the procedure is ambiguous, poorly formatted, or hard to follow in the field, workers will drift away from it out of practical necessity, and every other tool weakens with it. A usable procedure makes adherence easy. A procedure that fights the user makes adherence a constant battle the user eventually loses.

The same holds for the rest. Self-checking needs clear component identification and expected results. Independent verification and peer checks need critical steps identified. Place-keeping needs the document to provide the aids. Three-way communication needs step language written to support it. A questioning attitude needs clear points where stopping is expected.

Design choices can also quietly defeat the tools. A step that bundles several actions gives a self-check nothing clean to verify. An action buried inside a note, caution, or warning, another of the 18 error traps, may never be performed at all, because workers reasonably read cautions as information.

How do you build a procedure program that supports the tools?

Design the tools and the procedures together. An organization serious about human performance can't treat them as separate initiatives owned by different groups. In practice, that means four things:

1. Write to a human-factored standard. The Procedure Professionals Association's AP-907-005 Procedure Writing Standard, Revision 4 (December 2024), is the industry reference for step structure, conditional steps, sign-offs, place-keeping, and the placement of notes, cautions, and warnings. Writing to it builds support for the tools into every document. Learn more in [What Is Human-Factored Procedure Development?](HUMAN-FACTORED POST URL)
2. Identify critical steps. Mark the steps where an error can't be undone, so peer checks and independent verification land in the right places.
3. Build the cues into the document. Place-keeping marks, self-check cues, and hold points belong in the procedure itself, not bolted on through separate training.
4. Train writers in human performance, not only writing. Writers who understand the tools produce procedures that enable them. Our [PPA Writer Certification Training Course](PPA PAGE URL) prepares writers for the PPA certification exam and teaches this discipline.

When procedures and human performance tools are designed as one system, the tools become almost automatic. When they're designed separately, the organization ends up training habits that its own procedures work against.

The bottom line

Pre-job briefings, self-checking, three-way communication, peer checking, independent verification, place-keeping, questioning attitude, and procedure adherence are the practical techniques that catch human error before it reaches the work. Every one of them is enabled or undermined by procedure design. A program that writes its procedures to support the tools makes them second nature. A program that treats them separately trains habits its own documents work against.

Quick FAQ

What are human performance tools? Human performance tools are practical, repeatable techniques that reduce human error in high-consequence work. The core set includes pre-job briefings, self-checking (STAR), three-way communication, peer checking, independent verification, place-keeping, questioning attitude, and procedure use and adherence.

Where do human performance tools come from? They developed from human performance research in commercial nuclear power, aviation, and other high-reliability industries. The U.S. Department of Energy's Human Performance Improvement Handbook (DOE-HDBK-1028-2009) is a widely used public reference.

How do procedures affect human performance tools? Each tool depends on procedure design. Self-checking needs clear component identification, independent verification needs identified critical steps, place-keeping needs aids built into the document, and adherence depends on procedures being usable in the field.

What is the most important human performance tool? Procedure use and adherence ties the others together, but it depends on procedure usability. If a procedure is hard to follow, workers drift from it and every other tool weakens. That is why usable, human-factored procedures are the foundation the whole toolset rests on.

What does STAR stand for? Stop, Think, Act, Review. It is the self-checking technique a worker uses before and after an action to confirm the right component, the right action, and the expected result.
