What is Time Series Analysis?
Time series analysis involves examining data that changes over time or where time is a variable in the outcomes. Time isn’t just a data point; it’s the primary axis on which the data is based.
The main difference with time series analysis is that data is collected at regular time intervals. This helps identify patterns in the data, forming trends, cycles, or seasonal variations. With a consistent time frame of historical data, time series forecasting becomes a valuable tool for predicting future data. Time’s crucial role as a variable in data across industries makes time series analysis widely applicable. Explore a few examples outlined below.
6 Real-world Examples of Time Series Analysis in Various Industries
Example 1: Health Authority Enhances Patient Care
Problem: Inefficient resource use and rising costs of care and operations over time.
Solution: Utilizing data analytics, a prominent health authority conducted a comprehensive analysis of patient data. Examining historical data on patient stays, treatments, and conditions, they identified optimal times for administering medication, resulting in reduced average length of stay and cost savings for both patients and the system.
Insight: Time series analysis in healthcare extends beyond patient care to chronic disease research and epidemic-scale studies. Tracking chronic diseases over time and analyzing patient data using time series methods contribute to advancements in the field.
Example 2: Retail Giant Identifies Sales Opportunities
Problem: Slow data analysis affecting decision-making days before events.
Solution: A leading retail giant’s front-office team integrated all data sources to gain a comprehensive view. Implementing time series analysis dashboards, they swiftly identified sales opportunities by forecasting against seasonal trends. Proactive measures were taken to increase ticket sales for upcoming events based on real-time insights.

Example 3: Manufacturing Company Improves Forecasting Accuracy
Problem: Inaccurate and time-consuming operations, manufacturing, and sales forecasting.
Solution: A manufacturing company revamped its forecasting process using time series analysis and modeling. By leveraging better data and faster analysis, they reduced analysis time from one day to one hour. Accurate forecasts in supply chain and manufacturing processes led to significant cost reductions in inventory, supply chain, labor, and capital equipment.
Insight: Time series analysis proves invaluable in optimizing forecasting models, enhancing accuracy, and streamlining operations in manufacturing.
Example 4: Marketing Analytics Scaling for Media Clients
Problem: Evolving marketing technologies making it challenging to quickly analyze information for media clients.
Solution: An analytics firm centralizes over 100 data sources using Tableau, allowing quick data retrieval and the creation of custom dashboards. Time series analysis aids in media forecasting, enabling the firm to develop insightful “what if” analyses. This empowers clients to make informed decisions about marketing investments.
Insight: Time series analysis combined with data centralization is crucial for scaling marketing analytics, providing clients with actionable insights.
Example 5: Streamlining IT Costs Through Self-Service Analytics
Problem: Business decisions based on static reports, consuming time and resources.
Solution: A retail group enables department staff with self-service analytics in Tableau, reducing IT costs by 20%. Time series analysis is applied for accurate forecasting of retail and IT trends, optimizing product orders and resource allocation.
Insight: Time series analysis aids in accurate forecasting for retail and IT trends, optimizing resource allocation, and reducing IT costs.
Example 6: Innovative Use of Data Analytics in Auditing Processes
Problem: Traditional audits were time-consuming and lacked value addition.
Solution: An organization in the energy sector used Tableau to analyze a year’s worth of data, uncovering trends in financial processes. This data-driven approach revolutionized their auditing processes, providing deeper insights into the financial health of the organization.
Insight: Time series analysis proves instrumental in data-driven audits, providing a comprehensive view of historical data and uncovering trends for better decision-making.
These real-world examples showcase the versatility and impact of time series analysis across different industries, emphasizing its crucial role in data-driven decision-making and business optimization.
