Over the short span of time AI has become an important part of the software development processes, augmenting decision making and analysis on various levels and stages. It also has become a major stumbling block and there’s plenty of controversy around its usage. There is a popular opinion about AI delivering results that are too generic or too ambiguous or do not offer the depth and precision of the level that is required. I would say that this can be true, because today’s AI tools largely depend on human input. That is why AI prompt design comes to the front of effective work with AI tools.


In this article, I’d like to focus on a specific kind of AI prompts - table-driven prompts. When composed correctly and with well defined goals in mind, these prompts can benefit the workflows and value streams in all of your software development processes. They can greatly cut down time and effort for proper research and allow you to make very well-educated, data-driven decisions and prognoses, thus making your software development cycle more structured, predictable and error-proof.

What is a table-driven prompt: Advantages and Challenges

In natural language processing (NLP) a table-driven prompt is one of prompt-based AI learning paradigms that uses tables with rows and columns as a structure basis for information presentation.It features a simpler structural design yet requires a more intricate definition of the output. In this definition, each column represents a specific input and each row - a specific output. Its biggest difference from rule-based or formula-based prompts, where output fully relies on predefined rules, is that it relies on keywords and terms, and the dependency between input and output is much more flexible. This flexibility allows for a number of important benefits.


  • Adaptability


Since the input-output dependency of table-generating prompts is not so much cast iron, you can fine tune your input for more precise or condition-specific outputs. Meaning, we can shape table output by extending the query while leaving the table formula intact.

However, table-driven prompts require an educated approach to designing. Good hand-crafted table-driven prompts require deep domain expertise and also significant knowledge of NLP tools. Thus, the high sensitivity of the models to small input changes in table-driven prompts is not only a big advantage, but also a big challenge.

Understanding how Table-driven Prompt Engineering Boosts Decision Making and Efficiency in Development Process


Let’s start with an illustrative example. For instance, you need to decide on a technology stack in a field where there are plenty of available tools that are equally adequate for the task at first sight, but the choice would largely depend on details and specifics of your project. If you carry out this research manually, it may take a lot of time and valuable human efforts to gather all the data and to calculate possible scenarios. That is, provided that you have sufficient knowledge and understanding about the tools and what you are looking for. But you also have a very detailed list of non-functional requirements of your future system, such as the number of concurrent users, the number of transactions for a given period of time, etc., and a list of criteria that the system has to meet. Having this, you can compose a table-driven prompt or break it down into single-criteria tables for more accuracy and ask an AI to offer the best selection of the available technology to implement this. Having the AI fill out the cells for various condition sets will give you a detailed decision matrix.

There are plenty of ways to further enhance this task and make the final outcome even more input-sensitive and particular. For example, you can ask the AI to prioritize certain criteria over others. You can also add non-directly impacting conditions, such as availability of certain specialists at your disposal, their desire or readiness to use particular tools or learning curve necessary to master certain tech, and various limitations needed to be considered.  You can also ask AI to make several presentations of the output, starting from regular tables and graphs, or convert it to a decision tree, to create recommendations based on the output and any number of additional factors such as statistics, team preferences, resources allocation and others. Having research carried out and organized like this becomes a serious leverage when you need to make your decisions or defend your choices before stakeholders.

However there’s still one pivotal question.

How Can We Know That AI-generated Responses to Table-driven Prompts are Valid?


Table-generating prompting offers several qualities that can be easily verified and returns data that is both case-specific and transparently sourced. Of course, much depends on how well you design your prompts. In case with table-driven prompts, the dependency between the quality of the prompt and the quality of the response is tractable. Here are some qualities of table-driven prompts that make the output a very reliable source of information and a solid ground for decision-making.


  • Structured data collection


Table-driven prompts work with data that is structured in simple clusters and each data source is easy to trace and verify. The data is gathered systematically across various tasks, roles and workflows in a software development process, which makes it highly reliable and consistent.


  • Test-driven approach to prompts engineering


Working with table-driven prompts accommodates a lot of experimentation and leaves a lot of room for fine-tuning and testing various combinations of variables and their values to make the result much more situation-specific and the prompting process is tested extensively.


  • Contextual understanding


As information  in the well-designed prompt is broken down into simple table-driven dependencies, shifting values and priority of your input variables allows you to see the slightest shifts in the output. Thus, table-driven prompts are capable of taking into account a lot of contextual nuances and specific requirements in your development process. This makes the gathered data actionable.


  • Alignment with business requirements


The capacity for fine-tuning of table-driven prompts offers great possibilities when you need to consider many factors with varying priorities. Table-driven prompts can easily accommodate various user roles and business goals, making the output data very relevant and improving its utility for decision-making and analysis.


While there is no limit to where you can apply table-driven prompts to enhance your workflows, some tasks can specifically benefit from them.


  • Dashboards and analyses


Table-driven prompts are great for gathering analytic data. For example, if you need to analyze a stack of technologies for cross-compatibility with each other and then define the most likely possible issues when using them together. You can go even further and break it down for possible issues listed by priority and for various areas of application, for example, load, sales, learning curve, etc.


  • Decision table testing


Decision tables are extremely effective tools used to manage various types of requirements and advanced QA tasks. Using table-driven prompts, QA engineers can quickly verify if all possible combinations of testing conditions and requirements are covered.


  • Text classification


Table-driven prompts are invaluable when you need to quickly analyze a bulk of text, for instance, an extensive article or a research paper and present the main theses as a table, especially when the source article lists several important takes and points of view on a subject in question.


  • Leveraging domain-specific knowledge


Table-generating prompts help utilize extensive and not always easily accessible domain-specific knowledge without using additional resources, such as research and testing time and efforts, learning domain-specific language, terminology and jargon.

Elements of a Well-Designed Prompt


As much as table-driven prompts enhance decision-making and workflows, it all still largely hangs on how well you design a prompt.


  1. Clear and Structured format


Defined columns and rows that would organize input and output in a logical and coherently codependent format are essential. You also will need to establish defined correlations between all the elements so that your output is concise.


  1. Contextual Relevance


The prompt should be very specific in relation to the task in question, containing all impacting conditions, variables, and, importantly, constraints. It also should contain detailed and unambiguous instructions to guide the AI for an effective response. Follow-up prompts, breaking down the original prompt into several, asking the AI to analyze previous outputs and putting  additional queries will all make the output more efficient.


  1. Extensive Prompt Testing


Composing a working prompt is usually a result of numerous attempts, so you should be prepared to use multiple input combinations to test what works best, and test the prompt rigorously.


  1. Full Issue Coverage


Even though designing a prompt and testing it usually is a great way to detect blank spots in the prompt itself, it is always useful to cover as much ground as possible in order to detect as many white spots in the original input as possible.


  1. Extensive Comparison


Table-driven prompts are great for comparative evaluation and when composing a prompt, it is important that you capitalize on this feature to get more transparent and accurate results. Using comparison is also a great means to test the prompt and look for blank spots in your query.


  1. AI Specifics


Knowing behavioral specifics of the AI model you are working with and considering them when designing a prompt can greatly enhance the output.


Some other Best Practices for table-generating prompt engineering I can name include using chain-of-thought reasoning and few-shot learning. Incorporating both of these techniques of interacting with AI will help you to greatly increase the relevance of your output and steer the responses in the desired direction.

Key Takeaways


Table-driven prompts can greatly enhance decision-making processes in your development by reducing research, brainstorming, discussions and arguments because when designed properly, they provide well-organized, objective information that is both well-grounded and free from opinionated takes.


However, designing an effective table-driven prompt takes certain skills and often improves by the way of trial and error. Table-driven prompts are highly sensitive to context, which is their great advantage, as it offers great flexibility and room for fine tuning. Itt also poses a challenge, because you need to consider a complex combination of factors to create such context with precision.
