In the world of Learning and Development (L&D), data analysis often feels daunting. Yet, as organizations strive to prove the impact of training and development initiatives, analyzing both structured and unstructured data is increasingly critical. Large language models (LLMs) like ChatGPT present an alluring shortcut, offering the promise of quick, AI-powered insights. Data analysis is a fabulous practical example of a level 1 AI use in L&D, automating tasks we do now. But these tools, designed as generative AI models for processing and generating text, are not built for computing numerical datasets or performing advanced statistical analysis. Instead, their strengths lie in discovery and interpretation of text-based information—a distinction every L&D professional must grasp.
How LLMs in Data Analysis Shine with Unstructured Data
Unlike traditional analytical tools, which are optimized for crunching numbers and datasets, LLMs excel at working with unstructured text. This includes training feedback, employee reviews, and open-ended survey responses—all crucial elements for L&D teams. LLMs can identify patterns, sentiments, and emerging trends in text, which would otherwise require hours of manual effort.
For example, LLMs can:
- Analyze Sentiment: Extract sentiments from learner feedback to gauge program success.
- Summarize Content: Create concise reports from lengthy training evaluations.
- Identify Trends: Detect common themes in employee skill gaps or development needs.
Moreover, when paired with traditional machine learning models, LLMs enhance their utility. While LLMs interpret text, machine learning algorithms can process numerical data to detect anomalies, predict learner outcomes, or model future training needs. However, the most practical application for LLMs in data analysis today lies not in creating new analyses but in natural language search and curation of existing assets. For example, they can help locate relevant dashboards or learning records based on a simple question, enabling L&D professionals to act faster and with greater confidence.
A Good Use Case: Unstructured Feedback Analysis
Imagine a scenario where an organization conducts a large-scale training program and collects post-training feedback through open-ended survey responses. The L&D team is tasked with identifying common themes and sentiments to evaluate the program’s effectiveness.
Here’s how an LLM in data analysis can help:
- The L&D team inputs thousands of textual responses into the LLM.
- The LLM identifies recurring phrases like “engaging instructor,” “confusing materials,” and “more hands-on activities.”
- It categorizes the feedback into actionable themes, such as content clarity, delivery style, and interactivity.
- The LLM summarizes the overall sentiment, showing that 80% of responses were positive, but a subset mentioned challenges with clarity.
This saves the L&D team weeks of manual analysis while providing clear insights to refine future training initiatives. Since this task revolves around understanding unstructured text data, it plays to the LLM’s strengths in data analysis.
A Bad Use Case: Calculating Training ROI
Now consider an L&D leader wanting to calculate the return on investment (ROI) of a recent leadership development program. This involves correlating training costs, participant performance data, and organizational financial outcomes to identify measurable business impact.
Here’s why LLMs fall short:
- Calculating ROI requires processing structured numerical data like participant scores, promotion rates, and revenue changes.
- LLMs are not designed to perform mathematical computations or generate statistical models from numerical datasets.
- If fed a poorly structured query like “What’s the ROI of this program?” an LLM might hallucinate an answer, presenting plausible-sounding but inaccurate or irrelevant information.
- The L&D team would need to manually validate any insights or redo the analysis with proper tools, wasting time and increasing the risk of errors.
This example highlights the limitations of LLMs in data analysis when dealing with numbers or complex calculations, reinforcing the need for traditional data analysis tools for such tasks. There’s a natural tendency to look for speed when using AI, but needs to be done without sacrificing effectiveness.
Focus on Discovery: LLMs in Data Analysis as Search and Curation Tools
Given these limitations, the real power of LLMs in data analysis for L&D lies in their ability to surface existing analyses and insights, rather than attempting to generate new ones from scratch. Here’s how LLMs can support discovery and curation:
- Natural Language Search: An L&D professional can type a query like, “What training programs had the highest engagement last quarter?” The internal instance of the LLM, if fed with internal data sources, could search available dashboards, reports, or training records to provide an answer without creating new data models.
- Asset Curation: If no existing analysis fully answers the query, the LLM (again pulling from internal data sources it’s fed) could identify relevant data sources and suggest the next steps, such as querying specific tables or visualizing key metrics.
This approach enhances efficiency, accuracy, and scalability by maximizing the use of vetted, human-created analytics assets. It also mitigates risks associated with generating entirely new outputs, keeping the focus on trusted data.
The Pragmatic Future of LLMs in Data Analysis for L&D
While LLMs are not suitable for traditional data analytics, their potential for text analysis and discovery remains significant. Combining their natural language capabilities with other AI models offers a powerful toolkit for L&D teams seeking actionable insights without the need for deep technical expertise.
By embracing LLMs in data analysis as tools for discovery rather than computation, L&D professionals can bridge the gap between the growing complexity of data and the need for fast, meaningful insights. This pragmatic approach positions L&D teams to make data-driven decisions with confidence, leveraging the best of human and AI expertise.
In the end, LLMs in data analysis are not the solution for every data challenge, but they are a valuable ally for navigating the text-heavy world of learning and development.
