Human Performance Management Best Practice 3 – Qualify, Verify, and Validate

StrategyDriven Human Performance Management Best Practice ArticleHuman error reduction not only applies to the performance of operational activities but to analytical tasks as well. Errors made during performance of these tasks frequently go unnoticed at the time of occurrence, only to become consequentially evident when action is taken based on the errant analysis. These latent errors can have an equally devastating financial, environmental, asset and human impact as operational performance errors; simply occurring with greater time separation between the error and the event. Therefore, human error reduction must be applied to these activities too.[wcm_restrict plans=”41190, 25542, 25653″]

Analytical work deals largely with the manipulation of data into usable information. Thus, the error reduction tools focused on analytical work target data quality and calculational accuracy. These tools are Qualify, Verify, and Validate or QV&V.

Application

Used during the performance of analytical work, such as that performed by engineers, from which an error could result in a substantially adverse outcome when acted upon.

Examples

  • Engineer performing a design calculation to determine the needed rating of a pump or other component
  • Chemist performing a calculation to determine the amount of chemical to add to a system
  • Bank loan officer calculating a borrower’s home mortgage payment

Definition

Qualify: A data quality check during which the data is examined for situational relevance and accuracy. The accuracy check includes an assessment of instrument accuracy and/or the reliability/reputation of external sources. A calculational quality check assesses the relevance of the qualifications of those individuals performing the calculations.

Verify: Data accuracy is confirmed through comparison with equally reliable, independent sources. Calculations are checked by independent determinations may by an equally qualified individual.

Validate: Data and calculation check that assesses consistency and evaluates the data/calculation relative to past experience and expert judgment.

Final Thought…

The QV&V tool applies to both the data and calculations of analytical work. These tools are typically performed sequentially as:

  • Qualify data
  • Verify data
  • Validate data
  • Qualify calculations
  • Verify calculations
  • Validate calculations

StrategyDriven Human Performance Management Forum

Excellent business strategies fail to deliver superior results when not executed well. Subsequently, consistent, high-quality human performance becomes a critical component to successfully achieving the organization’s goals.

Yet, being human means making errors. Even well-intentioned, hardworking employees will make 3 errors out of every 100 actions taken simply because of the human condition. Thus, the question of achieving excellent human performances is twofold… how can the human error rate be minimized and how can business systems be structured such that human errors don’t result in costly or catastrophic failures?

Focus of the Human Performance Management Forum

Materials within the Human Performance Management Forum focus on those principles and best practices implemented at leading organizations to ensure consistent, high-quality human performance appropriately balanced with the need for cost-conscious efficiency. The following articles, podcasts, documents, and resources cover those topics critical to an exceptional human performance management.

Warning Flags

Human Performance Warning Flag 1 – Peer Checking Everything

StrategyDriven Human Performance Management Warning Flag ArticlePerforming operational tasks is no different than administrative work or project activities – elevate all tasks to a level of equal importance and they all become unimportant. As previously defined in StrategyDriven Human Performance Management Best Practice 2 – Peer Checking, activities that should be peer checked are those irreversible actions presenting a severe adverse consequence if an error is made. If all activities are peer checked, including those that are either reversible and/or have little consequence if a performance error occurs, then all activities are elevated to an equal level of importance; unnecessarily diminishing productivity and inviting complacency in the performance of truly important tasks.[wcm_restrict plans=”41251, 25542, 25653″]

Therein lies the greatest problem with peer checking all activities. The performance of peer checking requires an additional resource which necessarily reduces productivity. These individuals may subsequently feel added time pressure that drives them to hurriedly perform the peer checked; limiting the tool’s effectiveness in reducing errors. Additionally, with all activities being reviewed, the importance of consequential activities on the performer and a feeling that the checker will prevent an error may result in diminished effectiveness of the performer’s self checking practice. Proper assessment of activities and limited use of peer checking as an error reduction tool is therefore critically important to implementing an effective peer checking performance standard.

Peer checking all activities eliminates the distinction between those evolutions that are irreversibly consequential and those that do not have immediate consequences. As leaders, it is our responsibility to ensure proper prioritization of activities and development and application of performance standards that maximize the organization’s opportunity for success. While not all inclusive, the four lists below, Process-Based Warning Flags, Process Execution Warning Flags – Behaviors, Potential, Observable Results, and Potential Causes, are designed to help organization leaders to recognize whether their organization is treating all operational activities equally when applying the peer checking tool; diminishing productivity and risking complacency. Only after a problem is recognized and its causes identified can the needed action be taken to move the organization toward improved performance.

Process-Based Warning Flags

  • No clear definition exists for what activities should be peer checked
  • Lack of specific, documented examples of activities requiring a peer check
  • Effective peer checking performance is not included in the management observation program, such as embedding reviews within program checklists
  • Managers and supervisors are not trained on appropriate peer checking practices and standards

Process Execution Warning Flags – Behaviors

  • Appropriate peer checking practices are not communicated (manager to supervisor and/or supervisor to employee)
  • Employees take the initiative to perform peer checking for reversible and/or non-consequential activities
  • Managers and supervisors insufficiently or ineffectively reinforce human performance tool use
  • Managers and supervisors expect all activities to be peer checked; particularly those carried out at important watch stations such as in a main control room or safety control system panels

Potential, Observable Results

  • Productivity decline with no corresponding performance accuracy increase
  • Performance complacency and potential decline in performance accuracy including diminished self checking performance
  • High or rising number human errors that should have been prevented by peer checking for which an adverse consequence was avoided because of another preventive measure
  • Rise in the number of near-miss events of consequence
    (The event did not occur because of the operating condition or circumstance and not because of a positive, direct event prevention mechanism.)
  • Consequential event occurrence including financial loss, environmental damage, equipment damage, and human injury and/or death

Potential Causes

  • Lack of understanding of the effectiveness limits of the peer checking tool
  • Inappropriate value association with the peer checking tool by executives, managers, supervisors, and/or employees
  • Overly aggressive use of the peer checking tool
  • Managers and/or supervisors do not correct employees who perform peer checks for reversible and/or non-consequential activities

Human Performance Management Best Practice 2 – Peer Checking

StrategyDriven Human Performance Management Best Practice ArticleEven the most well-intentioned and dedicated humans are fallible. Therefore, the challenge becomes one of minimizing human error.

While individual performed human performance tools can greatly reduce error rates, there exists some circumstances when even this resulting low error rate is intolerable. These situations are characterized by the immediacy of a highly adverse outcome should an action error be made. Thus, greater error avoidance must be built into the performance of these activities.[wcm_restrict plans=”41184, 25542, 25653″]

One such error reducing tool is the peer check. Peer checking engages an equally (and appropriately) qualified performer as a second verifier of the activity to be executed. Just as the performer, the peer checker self checks and verbalize is his/her concurrence or objection with the performer’s indicated actions prior to their being executed.

Application

For irreversible actions for which a highly adverse outcome would be realized if an error was made.

Definition

STOP: The action performer and peer checker cease all other activities and focuses on the action at hand.

THINK: The action performer and peer checker independently consider the action to be taken; reviewing associated procedures, device/equipment labeling, operational parameter indicators, and associated data as well as mentally defining the expected changes in the system or systems’ operating parameters once the action is taken. The action performer reads the instruction line item aloud, announces component to be operated and its final state position, and verbalizes the instrument(s) to be used to ensure a proper response is obtained once the component is operated – including the actual response to be observed. The peer checker states his/her concurrence or objection to the stated course of action. If agreement is reached, the activity is continued.

ACT: The action performer deliberately executes the desired action while monitoring the associated system(s) response. Before operating the component, the action performer again announces the component to be operated and its final state position. The peer checker states his/her concurrence or objection to the stated course of action. If agreement is reached, the action is performed.

REVIEW: The action performer verifies all expected system(s) responses occurred and that no unexpected changes are realized. When performing this verification, the action performer again verbalizes the desired and actual response obtained. The peer checker states his/her concurrence or objection to the verbalized outcomes observed.[/wcm_restrict][wcm_nonmember plans=”41184, 25542, 25653″]

Human Performance Management Best Practice 1b – Verbalized Self Checking

StrategyDriven Human Performance Management Best Practice ArticleEven the most well-intentioned and dedicated humans are fallible. Therefore, the challenge becomes one of minimizing human error.

Verbalizing the written word further engages the activity performer in the task at hand. By speaking the directions, the performer is driven to mentally register the assigned actions.[wcm_restrict plans=”41178, 25542, 25653″] Additionally, verbalization compels the performer to hear the instructions; reinforcing the action to be taken.

Verbalization of action steps as a part of the self checking process follows the same guidelines as those for demonstratively self checking and should be performed in conjunction with that technique to maximize self checking effectiveness. When verbalizing the self checking process, the performer reads the instructions, announces the equipment/controller to be manipulated, states the direction and magnitude of action, verbalizes is the expected response, and where the response is to be observed. The performer repeats these pronouncements during the activity’s execution.

Application

Used during the deliberate manipulation of physical equipment when the operator’s actions are consequential.

Examples

  • Plant operators manipulation of valves, breakers, and control switches
  • Data entry personnel keying important data; especially if no follow-on accuracy checks are to be performed
