How Historical Data Gets Used in Predictive Analytics
After recognizing the importance of historical data, the next step is figuring out how to put it to work. Businesses use a variety of techniques to turn past records into actionable insights, helping them anticipate future outcomes and improve operations. These methods pave the way for identifying patterns and setting benchmarks that guide decision-making and performance evaluation.
Finding Patterns and Trends
At the heart of predictive analytics is the ability to uncover patterns within historical data. Time series models are particularly useful for spotting recurring trends or seasonal behaviors. These models analyze data collected at consistent intervals, allowing businesses to predict future values based on historical patterns.
Another powerful tool is clustering models, which group similar data points together. This approach reveals relationships that might not be immediately obvious, such as customer segments or operational similarities. Meanwhile, anomaly detection models act like sentinels, identifying unusual patterns that could signal risks or opportunities. By learning what "normal" looks like, these models flag deviations that require attention.
However, even the best models rely on high-quality data. Collecting, cleaning, and preparing data is essential for generating reliable predictions. Once the data is ready, businesses use feature selection to focus on the variables most relevant to predicting specific outcomes.
A great example of pattern recognition in action comes from Geisinger Health. They analyzed health records from over 10,000 sepsis patients to create a predictive model that improved diagnosis and treatment. The result? A model that accurately identified patients with a high likelihood of survival.
These patterns not only enable predictions but also establish benchmarks for measuring performance.
Setting Performance Baselines
Once trends are identified, historical data helps create benchmarks that serve as reference points for future performance. These baselines make it easier to spot deviations and take proactive steps.
"Baseline data is the backbone of predictive maintenance. By establishing and maintaining accurate benchmarks, businesses can detect issues early, enhance equipment reliability, and save costs." – DXP Pacific
To build effective baselines, companies must collect data under optimal conditions and use reliable tools. The baselines should be both realistic and measurable within a set timeframe.
Consider a bridge construction project that used a tiered approach to baselines. By setting milestones at three levels - overall project goals, phase-specific targets, and weekly work packages - the project finished two months early and came in 5% under budget. Similarly, Intel refined its cost estimates during project planning by combining historical data with expert insights, demonstrating how baselines can evolve as more data becomes available.
Regularly updating baselines ensures they remain accurate and support ongoing predictive efforts.
Understanding Cause and Effect in Processes
Historical data does more than highlight trends - it helps businesses understand the causal relationships behind their processes. This deeper insight allows organizations to identify which factors truly influence outcomes, rather than mistaking correlation for causation.
Regression analysis is a key tool for uncovering these relationships. Harvard Business School Professor Jan Hammond explains:
"Regression allows us to gain insights into the structure of that relationship and provides measures of how well the data fit that relationship. Such insights can prove extremely valuable for analyzing historical trends and developing forecasts."
By combining statistical models, data mining, and machine learning, businesses can dig deeper into their data to understand not just what happened, but why it happened. This approach helps pinpoint risks and uncover opportunities.
For instance, a plastics and thin film manufacturer used historical equipment data to identify failure patterns. Their predictive maintenance program now saves $54,000 every month by reducing downtime and waste. Similarly, Building IQ applied causal analysis to improve energy efficiency in commercial buildings. By understanding the factors affecting energy use, their system cut HVAC energy consumption by 10–25% during regular operations.
The key to success lies in continuously monitoring model performance and updating models as new data comes in. This ensures businesses maintain an accurate understanding of cause-and-effect relationships, even as conditions change.
With these insights, historical data takes on a strategic role, driving smarter decisions and better outcomes.
Tools and Methods for Predictive Analytics
Historical data holds the key to understanding trends, but it’s the right tools and methods that turn those insights into actionable predictions. By combining advanced techniques like process mining and machine learning with meticulous data preparation, businesses can unlock predictive capabilities that improve operations and decision-making.
Process Mining Algorithms
Process mining algorithms use mathematical techniques to extract process models from business data. A great example of this is at Brussels Airport, where a combination of Random Forest and LSTM neural networks was used to predict baggage processing times. This approach reduced the mean absolute error to 56 minutes and improved accuracy by 5 minutes compared to static models. It also revealed critical factors influencing delays, such as flight schedules and arrival times. Once these patterns are identified, machine learning models can take over to forecast future outcomes.
Machine Learning Models
While process mining focuses on uncovering historical patterns, machine learning models are all about predicting what’s next. Predictive process mining leverages various machine learning algorithms, and the choice between supervised and unsupervised methods can greatly affect both accuracy and how easily results can be interpreted.
Supervised algorithms like support vector machines, regression models, decision trees, and random forests work well when past outcomes are clearly documented. These models are transparent, making it easier to understand their decision-making process.
Unsupervised methods such as RNNs and LSTMs are better suited for uncovering complex patterns but can be harder to interpret.
Deep learning models often deliver the highest accuracy, though they may come at the cost of explainability.
"The future of process management lies in a balanced integration of Object-Centric Process Mining (OCPM) and AI, leading to more efficient, compliant, and optimized operational processes."
– Prof.dr.ir. Wil van der Aalst, Process and Data Science, RWTH Aachen University
When choosing an algorithm, it’s essential to consider the goal. For applications requiring transparency - like regulatory compliance - supervised models are often the best choice. On the other hand, if accuracy is the primary objective, deep learning may be the way to go.
Data Preparation and Feature Engineering
Even the most advanced algorithms depend on high-quality data. That’s where data preparation and feature engineering come into play.
Data collection: Gather historical records, real-time feeds, and both structured and unstructured data.
Data cleansing: Address inconsistencies, such as missing values, using methods like mean or median imputation - or more advanced techniques.
Feature selection: Focus on identifying the most relevant variables for the prediction task.
Normalization and standardization: Ensure comparability between data on different scales, such as dollar amounts versus time measurements.
Outlier detection: Identify and correct unusual data points that could distort model accuracy.
Model validation is another critical step. Techniques like cross-validation help test a model’s stability and ensure it performs well on new data. Regular monitoring is also necessary to keep models updated as conditions change.
Practical Applications and Case Studies
Building on the previously discussed methods and tools, these real-world examples highlight how historical data can be applied effectively in predictive process analytics.

Tackling these hurdles is essential to turning historical data into actionable insights and long-term advantages.
Data Quality and Availability Issues
One of the biggest roadblocks in predictive analytics is poor data quality. In fact, up to 60% of the time in predictive projects is spent on data cleansing, and downtime costs can exceed $5,600 per minute. Problems like missing values, inconsistent formats, outdated records, and noise can throw predictions off course. For instance, inaccurate inventory data in retail can lead to flawed demand forecasts, while incomplete medical records in healthcare can delay critical interventions.
Another issue is data bias, which can distort predictions. To address this, organizations can start small - integrating a few key data elements and gradually expanding their datasets to boost model performance. Separating historical, new, and prediction data into distinct systems can also help streamline data management. Machine learning methods can assist by identifying and fixing missing values or outliers, while techniques like over-sampling, under-sampling, and SMOTE (Synthetic Minority Oversampling Technique) can tackle data bias.
Combining Historical and Real-Time Data
Integrating historical and real-time data offers more dynamic and accurate predictions but introduces its own set of challenges. Real-time data allows models to adapt to the latest information, but merging these sources can be technically demanding. For example, 76% of asset-intensive companies use predictive analytics to improve efficiency, and in the automotive sector, unplanned downtime can cost manufacturers $22,000 per minute.
Some success stories highlight the power of this integration. XMPro, for instance, helped mining operations reduce unplanned downtime by 25% by combining sensor data, operational logs, and historical analysis. Similarly, a manufacturer achieved a 30% drop in downtime by monitoring machine health through predictive analytics. Tools like Apache Kafka for data streaming and Apache Flink for stream processing are key to managing such integrations.
Building a strong predictive analytics framework starts with a solid data strategy. This includes planning for data collection, ensuring data quality, and setting up storage systems that can handle both historical and real-time data. Investing in AI tools, integrating real-time inputs like CRM systems or social media data, and assembling a cross-functional team of data scientists, IT experts, and business strategists are also critical steps.
Making Models Easy to Understand
Even the most accurate models can fall short if decision-makers don’t understand how they work. Striking a balance between accuracy and interpretability is essential. Simpler models like linear regression and decision trees are easier to explain, while more complex ones, such as neural networks, may require tools like LIME or SHAP to clarify predictions.
Feature selection and engineering can also improve both clarity and effectiveness. By focusing on the most relevant variables - often identified through correlation analysis - models become more transparent. Evaluating performance using metrics like Mean Absolute Error (MAE), Mean Squared Error (MSE), and R-squared (R²) for regression, or Precision, Recall, F1-score, and Area Under Curve (AUC) for classification, helps stakeholders grasp how well a model is performing. Ongoing monitoring and feedback loops ensure models stay accurate and aligned with business goals over time.
Addressing these challenges is key to unlocking the full potential of historical data, enabling businesses to make smarter, data-driven decisions and achieve sustainable growth.
