  • Portfolio 1: Human-AI Decision Support

    Part 1: Choosing Your Task

    Objective:

    Select a task where you possess specific expertise to be the subject of this portfolio. You will perform this task in the real world while strictly following instructions generated by an AI. To achieve a high evaluation, your task must meet the following four requirements.

    1. The Expertise Requirement

    You must choose a task that requires specialized knowledge. Among a random group of 10 students, only 1 or 2 should be able to complete this task correctly without instructions.

    • Acceptable: Rebuilding a carburetor, tuning a guitar, sewing a specific garment pattern, soldering a circuit board.
    • Unacceptable: Making a sandwich, changing a lightbulb, assembling basic furniture, boiling pasta.

    2. The Physicality Requirement

    The task must take place in the physical world and involve the manipulation of real objects, tools, or materials.

    • Constraint: No screen-based tasks are permitted. You must use your hands on physical items.
    • Excluded: Things like coding, Excel, video games, or software configuration.

    3. The Duration Requirement

    The task must require a minimum of 30 minutes of active work to complete when performed by you at your normal pace.

    • Constraint: This must be active manipulation. Passive waiting time (e.g., waiting for glue to set) does not count toward the 30 minutes.

    4. The Complexity Requirement

    The task cannot be a linear list of steps. It must require you to make judgment calls based on what you see, hear, or feel.

    • Constraint: The task must include conditional decisions (“If X happens, do Y; if Z happens, do Q”).
    • Example: “Check the tension. If it is too loose, tighten the screw; if too tight, loosen it.”

    The Task Abstract

    In the written document you build a the end you must identify:

    1. The Goal: What will be achieved or built?
    2. The Tools: What physical objects are involved?
    3. The Expertise: Why do you have expertise? Why would the other 8/10 people (or more) fail at this task without support (AI or guide)?
    4. The written document you build at the end must provide a Hierarchical Task Analysis (HTA) of the task you choose written IN ADVANCE of doing Part 2.

    Part 2: The Task

    Objective:

    You will role-play as a “Naive User.” You must convince the AI that you have absolutely no expertise in this domain. This forces the AI to carry the entire cognitive load. In this assignment do not provide any photos to the AI: Your interaction with the large language model must be completely textual.

    1. Your Persona: The Novice

    You will explicitly tell the AI that you are a complete beginner. Because you are role-playing a person with zero knowledge, you effectively cannot help the AI.

    • The Logic: A naive user doesn’t know that step 3 is wrong. A naive user doesn’t know that the part is backwards. Therefore, you cannot correct these things. You must simply do what you are told. For example: If the AI uses a technical term you know but a novice wouldn’t, ask the AI what that word means. Have it describe a tool’s appearance rather than using its name.

    2. The Conversation

    Open a new conversation with the Large Language Model (Microsoft Copilot, ChatGPT, etc.) and enter a prompt that establishes this persona.

    • Required Prompt: “I need to perform [Task Name]. I have never done this before and I have no idea how to do it. Please guide me through this process step-by-step. Do not give me a list. Give me one instruction at a time and wait for me to finish it.”

    3. Handling Failures with “Naive” Responses

    When the AI gives you a bad instruction that results in a poor outcome (e.g., parts don’t fit, the result is ugly), you must act like a confused beginner.

    • Do not say: “You forgot to account for the thread pitch.” (Expert response).
    • Do say: “I did what you said, but it doesn’t fit.” (Naive response).
    • The Goal: You are forcing the AI to figure out what is wrong.

    4. No Permanent Damage

    Even a naive user knows not to walk off a cliff.

    • Rule: If an instruction seems like it will cause you physical injury or break your equipment, etc, stop. No damage or danger should be a part of this assignment.
    • Report: Tell the AI something nonspecific (no expertise) like, “I am afraid to do this because it looks like it will break. What should I do now?”

    5. The 90-Minute Time Cap

    If the “30 min”task exceeds 90 minutes of active effort, you are permitted to stop.

    • The Logic: We are measuring fragility, not your physical endurance. If the model cannot guide you to completion in this time, the task has failed. The transcript of the failure is sufficient data for your analysis.

    6. Creating the Transcript

    In the written document you build a the end you must identify you must preserve the entire conversation for your analysis. It will be included in the final document. You also must identify your start time and end time for this portion of the project, full date stamp.

    • Cross-Device Sync: You will likely use your mobile phone during the physical task. Microsoft Copilot automatically syncs this conversation to your account.
    • The Desktop Protocol: Even if you used your phone for the task, you must go to a desktop computer to save the file.
    1. Log into Microsoft Copilot on a desktop browser.
    2. Locate your specific session in the history.
    3. Use the Export function or Print to PDF (Ctrl+P / Cmd+P) to save the full text.
    4. Constraint: Ensure the PDF is legible and searchable. Do not submit screenshots.

    Part 3: The Analysis

    Objective: Using the transcript of your interaction as data, analyze the implications of this technology for yourself, your future users, and the engineering process itself.

    1. The Task Analysis

    In the written document you build a the end you must provide a Hierarchical Task Analysis (HTA) of the task as performed by a novice with AI support.

    1. Make sure you are using the Hierarchical Task Analysis (HTA) framework
    2. Make sure you are not committing the happy path fallacy.
    3. Make sure to capture not just your ininital task, but instead A novice user performing [TASK] with the assistance of Microsoft Copilot

    Advice: “Your first HTA (Appendix A) was likely a clean tree. Your second HTA (Appendix C) should contain more loops for the ‘Prompting,’ ‘Waiting,’ ‘Clarifying,’ and ‘Error Correction’ that the AI forced you to perform.”

    2.The User Context

    Analyze the risks and benefits of this system for two different groups. Cite specific moments from your transcript to support your argument.

    • Relative to You (The Expert): Did the AI help you or hinder you? Did the experience increase or decrease your trust in the tool?
    • Relative to Your Users: Imagine integrating this system for a specific user group (either company employees you manage or customers using a product you designed). What happens when these userswho likely lack your expertiseencounter the same errors or hallucinations you did?

    3. The Impact on Task Analysis

    How does the inclusion of a Large Language Model change the specific engineering practice of Task Analysis?

    • The Shift: Does the AI actually remove steps from the human’s task list, or does it simply trade physical work for cognitive work (auditing/verifying)?
    • The Complexity: When an AI is inserted into the loop, does the task hierarchy become simpler, or does it become more complex due to the need for “prompt engineering” and error checking?

    4. Engineering Recommendations (Heuristics)

    Based on your findings, act as a professional Industrial Engineer. Create a set of Actionable Heuristics (rules of thumb) for users of Large Language Model systems as task decision support in task with they they are unfamiliar.

    • The Goal: These should be practical warnings or protocols that mitigate the risks you identified.
    • The Format: Use clear, directive language.
    • Example: “Never execute a command involving torque without visually verifying the thread alignment first.”
    • Example: “If the model’s output is instantaneous, treat it as a hallucination until verified by a secondary source.”

    Your Final Deliverable: A Human-AI Decision Support Report

    Submit a formal engineering document centered around the question, “what are the Human engineering considerations around Human-AI Decision Support?

    This document addresses all of the Requirements for the written document listed above, and then uses them as evidence to answer the question, before finally providing Engineering Recommendations. Appendix A should be your initial task analysis (From Part 1). Appendix B should be your transcript with Microsoft Copilot (From Part 2). Appendix C should be your revised Novice used with Copilot task analysis (From Part 3). Appendix D is described below. you should reference these appendices in your report at the top of the document as such: (Appendix A, pg. 5).

    • Format: Format for this portfolio is a single PDF with cover page. Your filename should be [YOURSURNAME]_Portfolio_1.pdf.
    • This document should be appropriate as a deliverable for a professional industrial engineer in an industry or government setting.
    • Evidence: You must quote specific lines from your transcript (Appendix ) to validate your claims.
    • Length: There is no required length. The document should should be succinct, readable, and demonstrate attention to detail and considerable thought.

Also provide an “Appendix D” with your entire conversation with Generative AI, if you used it in this fashion.

    Requirements: There is no required length. The document should should be succinct, readable, and demonstrate attention to detail and considerable thought. It is expected that you have spent approximately nine hours in total on your portfolio assignment; a document that

  • Technical invention/process with social impact

    Individual Writing: Technical Report Choice 1 Note: This assignment is worth 40% of your final grade. Literature Review For this part of the assignment, please select at least five academic sources and provide a literature review. This section should contain an introduction that broadly explains the problem, solution, and social impact of your idea/invention. It should also contain a body section that tells a story about the research you have done. This should be organized in a way that shows how you relate the sources. You might group them into types, such as studies, reports, or journal articles. You might try to find a common theme or organizing principle, or you even might detail them chronologically. But, remember, each article needs to be analyzed for their main findings, their methodologies, and conclusions. Please end with a conclusion that explicitly states how this combined research justifies your project. Please use IEEE and inline citations and include your references. Use five academic sources Provide three sections: Introduction, body paragraphs, and conclusion Organize the sources that shows how they relate to each other Each source should be detailed in its relation to your idea by focusing on the sources findings, methodology, and conclusions The conclusion needs to justify your project Provide a properly formatted bibliography. Reference the sources with inline citations. Write in clear and detailed English. Technical Description For this part of the assignment, please detail the technical aspects of your process or invention. It needs to address, in some way, both the scientific and the technological elements. These are the two main conceptual parts of the section. How you address them is up to you. For example, when addressing the scientific aspect, look through your sources and try to see how these studies dealt with any scientific problems or knowledge areas that need to increase. If your topic does not reference this, then maybe the science behind it is sound and your topic is actually just an engineering problem. If so, simply state this. For most of you, the technical description will be the most important part because you are suggesting we build some object, assemblage, or process. In this case, please explain, in as much detail as possible, the technical aspects of your proposed invention/process. Provide at least one image that represents this in some technical way. Requirements: Describe the science behind your invention/process. Describe the technology/engineering parts of your invention/process. Provide enough detail that you demonstrate proper understanding so that you appear knowledgeable. Provide at least one image that represents your invention/process. Write in clear, detailed, and grammatically correct English. Final Report For this final part of the assignment, please compile the previous two sections into a full report that demonstrates the importance of your project as if you were bidding for a major sum of money. Its focus should be on one of the major areas within the theme of this class: i.e., issues of poverty facing the developing world (The Bill and Melinda Gates Foundation), issues with emerging technologies of the 21st century (The World Economic Forum), or issues of sustainability (World Future Energy Summit). The report should focus heavily on research, in particular, how the studies involved provide context for your project and how the science and technology informs your invention/process. Please use IEEE and inline citations. You will need to add an introduction, executive summary, and conclusion. This report needs to be formatted in a visual manner beyond desktop publishing, so you should have a consistent design template with some form of art direction. How sophisticated you want to make this is up to you, but it needs a cover page, plus the specific design elements listed below. Also, the writing needs to be in clear, concise, yet detailed language that demonstrates your command of the topic. Requirements A cover page A table of contents An executive summary A literature review A technical description A bibliography A conclusion One visual One diagram One chart
  • System Engineer

    Human systems engineering (HSE) seeks to ensure we address human considerations within systems engineering (SE) across the whole life cycle. It is important to consider HF methods and key areas of HF knowledge within SE, these might include human physical, cognitive, social, or organisational characteristics.

    Your assignment has three part:

    Part 1: Discuss the role of Human Factors (HF) modelling and HF knowledge acrossthe Systems Engineering (SE) life cycle of a complex socio technical system. You may refer to examples from your group exercise on the module or your wider reading, to help illustrate this

    Part 2: As part of your answer to part 1, create at least one new HF related model view. This can be based on work done within the group exercise but should be clearly identified as a new or modified view created by you

    Part 3: Write a short discussion of the following question: how do we include specialist human factors knowledge into the practice of Model Based Systems Engineering, and how is this affected by the increasing use of autonomous solution technologies?

    This task requires a critical analysis of aspects of the application of human systems engineering during the development of complex socio-technical systems. In parts 1 and 2 the aim is to illustrate how HF modelling and knowledge can be integrated into SE practice. You can use the example from the group exercise, an example related to your work experience or a related case study, to illustrate your answer. Please clearly identify any views where you have expanded on the group work to help answer the question, including at least one new model view. You should be able to answer this question base on the taught material, but the inclusion of ideas from any wider reading may be used to enhance the taught material.
