Challenges of prompt engineering

Understanding the challenges associated with prompt engineering is key to using prompts effectively and responsibly. Here are some potential issues you may encounter:

• • Trial and error required: Crafting effective prompts often involves multiple iterations before achieving the desired outcome.
  • Model limitations: Even with well-structured prompts, AI models may still produce errors, hallucinations, or irrelevant results.
  • Scalability issues: Designing consistent, high-quality prompts for enterprise-level use cases can be time consuming and difficult to maintain.
  • Context window constraints: AI models can only process a limited amount of information at once, which restricts the depth of input.
  • Bias and fairness risks: Poorly phrased prompts may unintentionally reinforce stereotypes, misinformation, or harmful content.
  • Overreliance on prompts: Users may depend too heavily on clever prompting instead of combining it with other strategies like fine-tuning or retrieval-augmented generation (RAG).

By recognizing these challenges, prompt engineers can strike a balance between experimentation and structured best practices to make AI outputs more ethical and reliable.

Prompt engineering techniques

Prompt engineering is more than just asking questions; it’s also about the way you structure prompts. Some commonly used techniques include:

• • Zero-shot prompting: Asking the model to perform a task without providing examples, relying only on clear instructions.
  • Few-shot prompting: Including a handful of examples in the prompt to show the model the desired style, format, or logic.
  • Role prompting: Assigning the AI a persona or perspective (e.g., “You are a CMO”) to influence tone and expertise.
  • Chain-of-thought prompting: Encouraging the AI to explain reasoning step by step to improve accuracy in complex problem-solving.
  • Instruction-based prompting: Using explicit, structured commands such as “List three advantages and disadvantages of…” or “Summarize the key takeaways using bullet points.”
  • Context-rich prompting: Supplying additional background information, constraints, or data so the AI can tailor responses more precisely.
  • Iterative refinement: Adjusting and rephrasing prompts based on initial outputs until the AI consistently produces the desired result.

Prompt engineering best practices

Getting high-quality results from AI models is dependent on the ability to craft clear, detailed prompts. Here are some best practices you should utilize to help you do that:

Start with clear objectives

Before writing, define your goal. Are you in search of ideas, facts, or solutions? A vague prompt, such as “Tell me about marketing,” produces generic results, while a more detailed prompt, like “Explain three digital marketing strategies for B2B SaaS companies with under 50 employees,” yields a more detailed output.

Be specific about format

AI performs better with clear instructions, so it’s crucial to include details like length, tone, and format. Instead of requesting “A social media post about productivity,” you should ask for “A LinkedIn post under 150 words sharing three time-management tips for remote workers in a professional but conversational tone.”

Use examples to guide

Providing examples improves results. This technique, known as “few-shot prompting,” enables the AI to produce what you need.

Example structure:

Break complex tasks into steps

Large requests can lead to scattered results. Break tasks into steps or outline a process. Instead of: “Create a complete marketing plan for my startup,” try: “Help me create a marketing plan by identifying my target audience, suggesting three marketing channels, and outlining a content calendar.”

Iterate and refine

The first response isn’t always perfect, which is why it’s helpful to request follow-ups to refine the AI model’s output. Some examples of how you might do this include:

• • “Make this more conversational.”
  • “Add examples to point #2.”
  • “Shorten to 100 words but maintain the key message.”

Provide context

Provide the AI model with background information to deliver better-tailored responses. You can do this by taking the basic prompt, “Write a project update email,” and adding context like: “Write a project update email for our mobile app redesign. We’re two weeks behind schedule due to technical challenges; however, core features are 80% complete. The audience is our executive team.”

Experiment with approaches

Don’t just stop at the first working prompt. It’s important to try out different phrasings or structures for better results. You can utilize role-playing prompts like “Act as a marketing expert and analyze…” or “Explain this to a beginner vs. an expert.”

Prompt engineering examples

Here are a few more examples of well-structured prompts:

• • Technical documentation: Instead of simply asking, “Write API documentation,” a refined prompt might specify the target audience, preferred format, necessary sections, and examples, resulting in professional-grade output.
  • Code review: A basic “Review this code” prompt can be enhanced by asking the AI model to “Identify security vulnerabilities, ensure compliance with coding standards, and suggest performance improvements.”
  • Data analysis: A generic “Analyze this data” prompt becomes more effective when it includes specific business goals, key metrics, and visualization preferences.
  • Customer service: A strong customer service prompt includes tone guidelines, company policies, and clear escalation paths to ensure consistent, professional interactions.
