Purpose
Use this lesson to combine prompt design, testing, and review into one deliverable. The aim is to produce work that a colleague can review and act on, not merely text that sounds convincing.
Lesson Explanation
Scenario: Build a system that turns weekly team notes into an executive update.
Better instruction: Design the prompt system: input fields, transformation steps, output format, quality rubric, test cases, and human approval step. Include one sample input and expected output outline.
A professional prompt system is more than one clever message. It has defined inputs, reusable instructions, an output shape, tests for failure cases, and a human approval route. The capstone proves that you can make AI work repeatably for a real business process. The system includes inputs, steps, output format, rubric, tests, approval, and a sample case.
Work in a short cycle: provide the relevant input, state the result and limits, inspect the draft against the acceptance criteria, then revise the instruction when a requirement is missing. Keep the final human decision with the person responsible for the work.
Practice Questions
-
A one-off, cleverly worded prompt produces a great result once, but the same prompt fails when the input changes slightly next time. What does this lesson say distinguishes a professional prompt system from this?
View Answer
A professional prompt system has defined inputs, reusable instructions, an output shape, tests for failure cases, and a human approval route – not just one clever message.
-
What six components does this lesson name as part of a complete prompt system design?
View Answer
Input fields, transformation steps, output format, quality rubric, test cases, and a human approval step.
-
Write a prompt system design instruction for converting customer support tickets into a weekly summary report, following this lesson’s guidance.
View Answer
Something like: “Design the prompt system: input fields (ticket data), transformation steps (categorize, summarize, flag urgent items), output format (a structured weekly report), a quality rubric, test cases with sample tickets, and a human approval step before distribution.”
-
A prompt system has defined inputs and a clear output format, but no test cases showing how it handles unusual or incomplete inputs. What is missing, per this lesson?
View Answer
Tests for failure cases.
-
What does this lesson say the capstone project is meant to prove?
View Answer
That you can make AI work repeatably for a real business process, not just produce a one-time good result.
-
A system for turning meeting notes into summaries works well on a sample of clean, well-organized notes but has never been tested against messy or incomplete notes. What does this lesson suggest is missing?
View Answer
Test cases covering failure or edge cases, not just the ideal input scenario.
-
A completed prompt system includes defined inputs, transformation steps, an output format, a quality rubric, test cases, a human approval step, and a sample input/output pair. What does this reflect?
View Answer
A complete, professional prompt system following this lesson’s full guidance, drawing together the whole course’s principles.
-
Why does this lesson emphasize a “human approval step” as a required component of a prompt system, even after extensive design and testing?
View Answer
Consistent with earlier lessons on accountability and human review, even a well-tested system should retain a human checkpoint before output is used or distributed.
-
A prompt system’s quality rubric defines what a passing output looks like, consistent with the rubric principles from earlier in this Part. What earlier lesson does this connect to?
View Answer
Part 6, Lesson 1 (Creating an Evaluation Rubric).
-
Why does this lesson describe “reusable instructions” as a defining feature of a prompt system, rather than a single clever prompt?
View Answer
A single clever prompt may work once but isn’t designed to reliably handle variation – reusable instructions with defined inputs are built to work repeatably across different cases.
-
A designed prompt system includes one worked sample input and its expected output, alongside the system’s structure. What is the purpose of including this sample, per this lesson?
View Answer
It demonstrates concretely how the system is meant to work, making the abstract design tangible and testable.
-
How does this capstone lesson draw together earlier lessons on reusable templates, rubrics, and human handoffs into one integrated task?
View Answer
It combines templates (Part 6, Lesson 4), rubrics (Part 6, Lesson 1), and human review/handoff (Part 6, Lesson 5) into a single, complete, professional-grade prompt system design.
