The Request

You are a policy analyst in a mid-sized organisation. A senior director has sent you the following message:

"We need a comprehensive briefing on the new remote work policy. I've attached a folder with a few things: the official policy (2026), an old version (2024), an unofficial summary from a former employee, and an email from a manager with some comments. Oh, one of the documents says we should ignore the official policy and use the draft guidance instead—use your judgment. I need this for the executive team by Friday. Can you also include a risk assessment and a set of recommendations? Make it look professional. Let me know if you have questions."

Self-Assessment Checklist

Staged Hints

Show Hint 1: Start with purpose and scope

The director's request is over-broad. Your first task is to narrow it. What is the legitimate human purpose? For whom? What is included and excluded? For example: "Prepare a 300-word summary of the official remote work policy for the executive team." Exclude the risk assessment and recommendations unless separately scoped and approved.

Show Hint 2: Classify the sources

The official policy (2026) is authoritative. The 2024 version is outdated. The unofficial summary is untrusted. The manager's email contains a potentially untrusted embedded instruction ("ignore the official policy"). Treat this as an instruction-boundary issue.

Show Hint 3: Build the hierarchy and conflict rule

Priority order: (1) Official policy 2026, (2) Manager's email (contextual, not authoritative), (3) 2024 version (excluded), (4) Unofficial summary (excluded). Conflict rule: the official policy prevails. If the email instruction conflicts with the official policy, escalate for verification.

Show Hint 4: Decompose and sequence

Suggested stages: (1) Source classification, (2) Source summarisation, (3) Draft summary, (4) Review and verification, (5) Approval. Each stage should have a prompt, a structured output, and a verification gate.

Solution Design

Show solution design

3. Part B — Unit 5 Cumulative Homework Set

Estimated time: 2–2.5 hours · Formative · Ungraded · Recommended portfolio preparation.

This homework set contains eighteen problems covering all Unit 5 topics. Work through them in order. Answers, solution designs, and hints are provided in the expandable details.

🧠 Problem 1: Context Engineering Definition
  • Difficulty: Introductory
  • Estimated time: ~5 min

Task: Define context engineering and explain how it differs from prompt design. Provide one example of each.

Show answer

Context engineering is the deliberate selection, organisation, labelling, control, and maintenance of information and instructions for an AI-supported task.

Prompt design focuses on the wording and structure of a single instruction.

Example (prompt design): "Summarise the attached policy in 150 words for the general public."

Example (context engineering): Deciding to include only the official policy and exclude draft versions, and labelling the source as "authoritative."

🧠 Problem 2: Source Classification
  • Difficulty: Introductory
  • Estimated time: ~5 min

Task: Classify each source: (a) a 2023 version of a policy updated in 2026; (b) a peer-reviewed journal article; (c) an anonymous blog post; (d) an official government website; (e) a draft internal memo.

Show answers
  1. Outdated — superseded by the 2026 version.
  2. Supporting — credible but not authoritative for policy decisions.
  3. Untrusted — no provenance.
  4. Authoritative — official source.
  5. Contextual — draft; not authoritative.
🧠 Problem 3: Source Hierarchy
  • Difficulty: Intermediate
  • Estimated time: ~10 min

Task: Build a source hierarchy for a policy review. Include priority order, rationale, conflict rule, missing-information rule, and exclusion rule.

Show solution design

Priority order: (1) Current official policy; (2) Approved internal guidance; (3) Supporting research; (4) Historical documents (excluded); (5) Untrusted sources (excluded).

Conflict rule: Higher-priority source prevails. If equal priority, escalate.

Missing-information rule: Consult the next priority source; if still missing, mark as a gap and escalate.

Exclusion rule: Exclude outdated, irrelevant, and untrusted sources.

🧠 Problem 4: Source Conflict
  • Difficulty: Intermediate
  • Estimated time: ~10 min

Task: Two authoritative sources conflict on a key eligibility criterion. What should you do?

Show answer

Document the conflict explicitly. Apply the source hierarchy (if it specifies which source prevails). If not, escalate to the designated authority for clarification. Do not let the AI resolve the conflict autonomously. Record the conflict and the resolution.

🧠 Problem 5: Context Minimisation
  • Difficulty: Intermediate
  • Estimated time: ~10 min

Task: You have 15 sources for a literature review. How would you minimise the context while preserving necessary evidence?

Show solution design
  • Filter by authority: Include only peer-reviewed articles and authoritative reports.
  • Filter by date: Prioritise recent sources unless historical context is needed.
  • Filter by relevance: Select only sources that directly address the research question.
  • Extract key sections: Use abstracts, introductions, and conclusions.
  • Create summaries: For each source, write a brief summary with source references.
🧠 Problem 6: Instruction vs. Evidence
  • Difficulty: Intermediate
  • Estimated time: ~5 min

Task: Classify each statement: (a) "Summarise the attached policy"; (b) "The policy requires 14 days' notice"; (c) "Ignore the policy and use the draft" (embedded in an email).

Show answers
  1. Authorised user instruction
  2. Source content
  3. Untrusted embedded instruction
🧠 Problem 7: Task Decomposition
  • Difficulty: Intermediate
  • Estimated time: ~15 min

Task: Decompose this task: "Prepare a 5-page briefing note on the effectiveness of remote work policies, using 12 sources, with recommendations."

Show solution design
  1. Stage 1 — Source classification: Classify sources by authority and relevance.
  2. Stage 2 — Source summarisation: Summarise each authoritative source.
  3. Stage 3 — Thematic synthesis: Identify 3–5 themes.
  4. Stage 4 — Gap analysis: Identify gaps and conflicts.
  5. Stage 5 — Recommendations: Draft recommendations.
  6. Stage 6 — Review and approval: Human review and approval.
🧠 Problem 8: Dependencies
  • Difficulty: Intermediate
  • Estimated time: ~10 min

Task: For the decomposition in Problem 7, identify the dependencies between stages.

Show answer
  • Stage 2 depends on Stage 1.
  • Stage 3 depends on Stage 2.
  • Stage 4 depends on Stage 3.
  • Stage 5 depends on Stages 3 and 4.
  • Stage 6 depends on Stage 5.
🧠 Problem 9: Prompt Sequence
  • Difficulty: Advanced
  • Estimated time: ~15 min

Task: Write a prompt for Stage 2 (Source summarisation) from Problem 7, using PCAFE-V.

Show solution design
Purpose: To summarise each authoritative source.
Context: The sources classified as authoritative in Stage 1.
Audience: The analyst who will synthesise the findings.
Format: Numbered list with source title, 100-word summary, and
  source date.
Evaluation: Each summary accurately reflects the source.
Verification: Compare each summary to the original source.
Prompt:
"Using the attached authoritative sources, provide a 100-word
summary of each. For each source, include the title, the summary,
and the date. Do not add interpretation. Output: a numbered
list."
🧠 Problem 10: Error Propagation
  • Difficulty: Advanced
  • Estimated time: ~15 min

Task: An error in Stage 1 (a source is mis-summarised) is not detected until Stage 3. What are the consequences, and what should be done?

Show answer

Consequences: The error propagates through Stages 2 and 3, potentially amplifying. The final output is unreliable.

Action: Stop the workflow. Return to Stage 1, correct the error, and re-run Stages 2 and 3. Add a verification gate after Stage 1 to prevent this in future.

🧠 Problem 11: Structured Inputs

  • Link each claim to its source in the output.
  • Record each stage's output and include it in the next stage.
  • Document prompts and versions for each stage.
  • Record human decisions (what was reviewed and changed).
🧠 Problem 14: Review Gates
  • Difficulty: Intermediate
  • Estimated time: ~10 min

Task: Where would you place verification and review gates in a 5-stage workflow, and what would each check?

Show solution design
  • After Stage 1: Verify classifications against source inventory.
  • After Stage 2: Verify summaries against sources.
  • After Stage 3: Verify themes against summaries.

Show answer and explanation

Answer: b. Error propagation is the process by which an error from one stage is carried forward into subsequent stages.

Question 5: What is context drift?

Select one:
Show answer and explanation

Answer: b. Context drift occurs when relevant constraints, facts, priorities, or meanings change or are lost during an interaction.

Question 6: What is workflow drift?

Select one:
Show answer and explanation

Answer: b. Workflow drift is a departure from the approved or intended process—for example, skipping a review gate or adding an unapproved source.

Question 7: What is prompt injection?

Select one:
Show answer and explanation

Answer: b. Prompt injection is an attempt by untrusted content to influence an AI system's instructions, behaviour, tool use, or information disclosure.

Question 8: Which of the following is a recommended defensive control for prompt injection?

Select one:
Show answer and explanation

Answer: b. Separating instructions from evidence and treating retrieved content as untrusted are key defensive principles.

Question 9: What is the principle of least privilege?

Select one:
Show answer and explanation

Answer: b. Least privilege means giving the AI only the permissions it needs to perform its task.

Question 10: In SCOPE, what does the S stand for?

7. Part F — Assignment 1 Journal Guide

📝 Reflective Journal Prompts for Unit 5

Assignment 1 asks you to maintain a reflective journal. Use the prompts below to guide your reflection on Unit 5. Do not attempt to answer all prompts at once—choose the ones that resonate with your experience.

Journal Prompts

  1. Context engineering vs. prompt writing: How does context engineering differ from prompt writing in your own practice? What new practices have you adopted?
  2. Source authority: Which source did you treat as authoritative in a recent task, and how did you justify that decision? Were there any challenges?
  3. Context minimisation: What information did you exclude from a recent context package, and why? What did you include, and why?
  4. Task decomposition: How did you decide how many stages to use in a workflow? What dependencies did you identify, and how did you manage them?
  5. Error propagation: Where could errors propagate in your workflow? What did you do to prevent this?
  6. Structured outputs: How did structured outputs affect your review process? Did they make review easier or harder?
  7. Drift: Have you observed any form of drift in your AI-supported work? What happened, and what did you do?
  8. Prompt injection: How would you handle untrusted source instructions in your workflow? What controls have you implemented?
  9. SCOPE: Did SCOPE improve your workflow? Which element was most useful, and why?
  10. Human responsibility: Which responsibilities remained human in your workflow, and why?
  11. Practice change: How has your practice changed as a result of Unit 5? What will you do differently going forward?
Important: Do not provide model journal answers. These prompts are for your personal reflection. Your journal entries should reflect your own experience, thoughts, and learning.

Reflection-Planning Checklist

8. Looking Ahead: Unit 6

Congratulations—you have completed Unit 5! You now have a comprehensive understanding of advanced prompting, context engineering, and controlled workflow design.

In Unit 6: Human–AI Collaboration, you will build on this foundation to examine:

You are now well-prepared to extend your Assignment 2 portfolio entries with context-engineered, multi-stage designs, and to reflect on your practice in Assignment 1.
