Additional Information

Final Report

 The report should be written similar to a grant proposal to a major funding agency or to acquire internal resources from your exployer.

 Reviewers of the proposal are not expected to be HRA experts or domain experts. Therefore, don’t assume any knowledge.

 i.e., a high level executive at an organization

 Consider this report being handed over to your boss to justify performing a HRA on a particularly high risk activity

 Why should I care about this problem?

 What is HRA?

 Why should I care about HRA?

 Hasn’t this already been done before?

 How exactly does this work?

 Will it improve something?

 What are the required resources?

 Can’t we just do something simpler, less computationally demanding?

Final Report Sections

 Section 1: Introduction (2pts)

 Problem Statement – what is the human error, why is it important, and why hasn’t someone found a solution previously?

 Relevance to HRA – why is HRA an appropriate tool to study this problem?

 Project Focus – what aspect of the problem will you focus on?

 Project Goals – what do you hope to gain from this HRA?

 Additional Notes:

 Refer to HW#2 justification

 Include support to justify importance for the problem AND focus

Final Report Sections

 Section 2: Literature Review (3 pts)

 Overview of 1st and 2nd Generation methods

 Detail of each method is not necessary

 Provide background for the field of HRA

 Prior methodological and domain specific work – Discuss advantages and disadvantages (limitations) of prior work.

 Prior work (not necessarily HRA) in your application domain (aerospace, healthcare, defense, etc.) to address the problem.

 Prior work (not necessarily HRA) to address your problem in other application domains. This should include general work to address problems associated with your theoretical focus in other domains.

Final Report Sections

 Section 2: Literature Review (3 pts)

 Additional Notes

 Prior work in the domain should cover any attempts to explore your focus of human

failure outside of HRA.

 Expect that an HRA has not been performed previously for your application. Therefore,

stating that fact is not sufficient to address this report requirement

 For example, if you’re studying cognitive load in maintenance environment, maybe physical

maintenance slips have been studied before in this domain but not from the perspective of

sensory processing

 Prior work in other application domains.

 For example, if you’re studying cognitive load in maintenance environments, maybe that has

not been addressed previously, but it has been addressed in other domains (driving, etc.)

Final Report Sections

 Section 3: Theoretical Focus (4 pts)

 Theory development

 Provide background on each theory. Link theories to the scope of the problem focus. Adhere to HW#3 requirements.

 Theory Interaction

 Describe the interaction between theories.

 Additional Notes

 HW #3. Update if there were major theoretical changes

 Similar to the grading of HW #3, points will be deducted if you do not show you have an understanding of the theory beyond the lecture bullet points.

 Cite scholarly literature

Final Report Sections

 Section 4: HRA Components (6 pts)

 Task Analysis - Adhere to HW#4 requirements.  Develop a cognitive task analysis and justify the content and formatting (hierarchical, procedural,

both).

 Provide a textual or diagrammatic representation of the process driven by the theoretical foundation.

 Justify the formatting, flow, taxonomy verbs, and cognitive theoretical scope of the task analysis.

 Unsafe Acts - Adhere to HW #5 requirements.  Develop a comprehensive list of unsafe acts for your problem categorized by Reason’s Error

Classification. The unsafe acts should be linked to each task.

 Justify the selection of the UAs and the link to the theoretical focus.

 PSFs - Adhere to HW #5 requirements.  Develop a list of PSFs linked to the unsafe acts. Describe each PSF and justify the link to each UA.

 Summary Table - Adhere to HW #5 requirements.

Final Report Sections

 Section 4: HRA Components (6 pts)

 Additional Notes

 HW #4 and #5 integration. Update if there were major changes. Address HW

requirements for any updates.

 Written justification is the most important piece of this section

Final Report Sections

 Section 5: HRA Method Selection (8 pts)

 Method Selection Questions

 Detail answers to each method selection question and discuss how each

question is linked to HRA components identified in Section 4.

 Based on the method selection questions, do existing methods meet the

modeling needs of your problem? If not, discuss missing criteria.

Final Report Sections

 Section 5: HRA Method Selection (8 pts)

 HRA Method Overview  Justification for Adapting and/or Combining Methods: If all criteria were not met during

HRA method selection, discuss how you will adapt or combine HRA methods.

 Justification for Use of Existing Method: If you use an existing method that has not been modified for your project (all criteria met), you must justify why the method is adequate in its current state to solve the problem.

 Implementation Overview: For both adapted and non-adapted (existing) HRA methods, provide detail on how to implement each step of your method.  Walk through the entire process (detailed methodological guideline for implementation by a

practitioner)

 Additional Notes

 Discuss inclusion/exclusion of each method based on overlapping coverage

 You must demonstrate written knowledge of the method in full detail

Final Report Sections

 Section 5: HRA Method Selection (8 pts)

 PSF Quantification - This can be discussed as part of the HRA method overview or discussed in its own section.  Strategy Overview and Justification: Describe your data collection strategy. Provide an overview of

how new and/or existing data will be collected and integrated in the selected HRA method.  Discuss why you have chosen this particular data collection approach instead of others.

 PSF Quantification Table: Include a table or bulleted list to detail how you plan to quantify each PSF identified in the HRA component integration.

 If existing data produced by a HRA method or derived from a database will be used instead of creating new data, this must be explicitly stated with a justification of why the existing data is contextually relevant for your problem focus.

 If new data will be collected, address study planning (population, recruitment, etc.). This is only required if you will not solely use data produced by the method or an existing database.

 Additional Notes  Each PSF must include a detailed individual plan for data collection through one of the data collection

methods discussed in lecture.

 This section is required, even if you are using data produced by the method. You must still detail how each PSF will be quantified.

Final Report Sections

 Section 6: Risk Mitigation (5 pts)

 Risk Prioritization

 Describe how the output of the HRA method (HEP) will quantitatively inform structured risk mitigation strategies. How will the most important risks be identified and prioritized?

 Risk Mitigation Strategy

 What risk mitigation strategies are appropriate (control, persuade, etc.)? Provide in tabular or bulleted form. Include a risk mitigation strategy for each identified unsafe act.

 Discuss how the risk mitigation strategies will differ based on the assigned PSFs for each task. How will you target different strategies based on the characteristics of the human population?

Final Report Sections

 Section 6: Risk Mitigation (5 pts)

 Additional Notes

 Consider how decision makers will use the information generated by the method

 Points will be deducted for lack of detail in the risk mitigation plans and direct

connection to each tabular line (PSFs and UAs)

 Points will be deducted if a heterogeneous target population is treated as

homogeneous

Final Report Sections

 Section 7: Discussion (3 pts)  Implementation Considerations

 How will the method be implemented in practice (policies, procedures, etc.)?

 Who will implement the method and what training will be provided?

 What is the amount of computational work and expertise required for the application?

 Stakeholder Acceptance  How will stakeholder acceptance be addressed?

 Additional Notes  Place yourself in the shoes of a manager tasked with overseeing the HRA

implementation and justifying it’s practicality to stakeholders

Final Report Sections

 Section 7: Discussion (3 pts)

 HRA Limitations  What are the limitations of the proposed theoretical scope (what’s not included)?

 Additional Notes  Points will be deducted for relevant limitations introduced in class that are not discussed
