Module 2: Core Elements of a Good Prompt

📘 Module 2: Core Elements of a Good Prompt

Writing a great prompt isn't about luck; it's about structure. To consistently get high-quality outputs from AI, you need to provide the right context and constraints. Use the formula below to ensure your prompts never miss the mark.

The PROMPT Formula

A comprehensive framework to structure your instructions for maximum clarity and accuracy:

P – Purpose: What do you want to achieve? (The core goal or task)
R – Role: Who should the AI act as? (Expertise, persona, or mindset)
O – Output format: How should the answer look? (Table, bullet points, code block, essay)
M – Method: What approach should the AI use? (Step-by-step, chain of thought, comparative analysis)
P – Parameters: Length, tone, style constraints (e.g., professional tone, under 300 words)
T – Target audience: Who is this for? (A 5-year-old, a senior executive, a non-technical stakeholder)

Complete Example: Fitness Planning

See how the formula maps to a real-world scenario:


Role: Act as a fitness coach
Context: I'm a beginner who hasn't exercised in 2 years
Task: Create a home workout plan
Format: Table with day, exercise, sets, reps
Constraints: 30 minutes per day, no equipment needed, 5 days per week
Audience: 35-year-old office worker
