Workshop: An introduction to time series analysis and forecasting
Main Goals of Time Series Analysis
Time series analysis plays a key role in helping businesses make sense of their data. By focusing on three main objectives - uncovering trends, identifying seasonality, and forecasting - it turns historical data into insights that guide strategic decisions and operational changes.
Finding Trends and Patterns
One of the first steps in time series analysis is identifying trends - those long-term movements in data that show whether key metrics are rising, falling, or staying steady over time. Trends provide a clear picture of how a business is evolving.
"Trend refers to the overall evolution of data over a long period of time. Trends can be upward (increasing), downward (decreasing), or null (no clear or significant movement in the data series over time). Trend analysis is crucial for detecting long-term patterns and identifying potential opportunities or risks." – Quix.io [6]
Trends can be split into two types: deterministic trends, which have identifiable causes, and stochastic trends, which appear random [5]. These trends may stay consistent or shift over time, depending on external factors [5].
For instance, Des Moines Public Schools used time series analysis on five years of student achievement data to spot at-risk students and monitor their progress [1]. Visualizing data through plots often helps uncover these trends [5].
In addition to trends, recurring patterns also play a significant role in understanding data behavior.
Analyzing Seasonal Changes
Seasonality is another major focus of time series analysis. Seasonal patterns are predictable fluctuations that repeat regularly, often influenced by factors like weather, holidays, or business cycles [8][9]. Recognizing these patterns is critical because they directly affect forecasting accuracy and resource management. Ignoring seasonality can lead to inaccurate predictions, while incorporating it into models enhances precision [9].
Take healthcare as an example: hospitals often analyze seasonal trends in admissions, which are influenced by flu seasons, weather changes, and holidays [12]. Unlike irregular cycles, seasonal patterns occur at consistent intervals and are typically more stable in duration and magnitude [7][9]. To properly capture these variations, businesses should collect at least 2–3 years of monthly data to identify trends, seasonal effects, and random fluctuations [3].
These seasonal insights, combined with trend analysis, lay the groundwork for accurate forecasting.
Predicting Future Data Points
The ultimate aim of time series analysis is forecasting - using historical data to predict future outcomes. This capability allows businesses to anticipate market demand, stock prices, or customer behavior, enabling them to act proactively instead of reactively [2]. Time series forecasting involves studying time-stamped historical data to make informed predictions about what’s ahead [4]. This helps businesses set realistic goals and quickly adapt to market changes [12].
Forecasting accuracy depends on understanding trends and seasonal patterns, as well as using high-quality data and the right forecasting methods. Techniques like ARIMA or machine learning are often used, depending on the characteristics of the data [11][7][10]. By leveraging these tools, businesses can allocate resources effectively, reduce risks, and maintain a competitive edge [2].
Business Uses of Time Series Analysis
Time series analysis is a powerful tool that businesses use to uncover trends, understand seasonal patterns, and make predictions that improve operations. By transforming raw data into meaningful insights, companies can fine-tune their strategies in areas like sales, finance, and workforce management.
Sales Forecasting
One of the most impactful uses of time series analysis is sales forecasting. By analyzing past sales data, businesses can anticipate future demand and make smarter decisions about inventory, marketing efforts, and resource allocation.
Here’s why this matters: companies that rely on time series forecasting grow 19% faster than those that operate purely on intuition[3]. Businesses that excel in data-driven forecasting can predict revenue with a margin of error as low as 5%, giving them a clear edge over competitors[3].
For example, an ARIMA(1,1,1) model applied to 12 months of sales data showed steady growth projections, achieving 15–30% lower error rates compared to traditional judgment-based methods[3]. To get the best results, businesses should use monthly sales data and update forecasts regularly with real-time information.
These insights don’t just stop at sales - they’re also crucial for financial planning and workforce management.
Financial Trend Analysis
Time series analysis plays a key role in financial decision-making, helping companies better manage investments and mitigate risks. By examining historical financial data, businesses can spot patterns that guide budget planning, investment strategies, and risk assessments. This allows for more accurate financial projections, including best-case and worst-case scenarios, and helps smooth production processes by anticipating cost fluctuations[13].
For instance, a financial analyst at XYZ Investment Firm used an ARIMA model to analyze Apple Inc.'s stock prices. By identifying trends and seasonal patterns in historical data, the model accurately predicted stock movements over six months, leading to profitable investment decisions[14].
To refine financial forecasts further, analysts can apply techniques like square root or log transformations to stabilize variance in non-linear data. Incorporating external factors, such as inflation or economic policy changes, and accounting for seasonal trends can also improve the accuracy of predictions[13].
Workforce and Resource Planning
Effective workforce planning, powered by time series analysis, can bring both operational and financial rewards. By studying historical staffing data, organizations can predict future workforce needs, optimize schedules, and ensure adequate coverage during busy periods.
Consider this: strategic workforce planning can save $6 million for every 100 employees[16]. Companies with advanced workforce planning systems often reduce labor costs by 15–20%, boost productivity by up to 15%, and adapt to market changes 40–60% faster compared to reactive approaches[16].
One example of this is an AI-driven solution capable of predicting business demand patterns and generating staffing schedules with 15-minute precision. This kind of precision can improve labor efficiency by as much as 25%, leading to better customer satisfaction, lower labor costs, and reduced employee burnout[16].
Time series analysis also helps businesses account for seasonal workforce demands, enabling them to prepare for fluctuations well in advance[15]. Combining this quantitative data with qualitative insights - like employee feedback and industry expertise - ensures decisions are both data-driven and human-centered.

Implementation Factors for Time Series Analysis
A successful time series analysis hinges on careful preparation and addressing key elements. The process starts with ensuring the data is accurate and reliable, as the quality of your analysis is only as good as the data you use.
Data Accuracy and Quality
The backbone of any dependable time series analysis is high-quality data. As Kyle Jones aptly states:
"The quality of time series analysis directly depends on the quality of the underlying data." [18]
To ensure this, your data should be consistently and regularly sampled. Preprocessing steps like filling in missing values, identifying and managing outliers, and normalizing metrics are crucial to avoid skewed results. Advanced analytical techniques, in particular, are highly sensitive to data issues, making these steps even more critical [20].
For instance, in controlled time series tests, staying within a +/-4% range for key metrics has been a common benchmark [20]. Organizing data in well-structured tables with complete and accurate time stamps is another essential step [19].
Alignment with Business Goals
Time series analysis becomes truly valuable when it aligns with your business objectives. Start by identifying 3–5 core metrics that directly relate to your goals. This alignment transforms raw data into meaningful insights that can guide decision-making [22].
A practical example of this is a product innovation team that shifted its focus from simply counting the number of ideas generated to tracking metrics like time-to-prototype and early user feedback. This change not only streamlined their innovation process but also led to a product with higher adoption rates within three months of its launch [22].

FAQs
How does time series analysis help businesses make better decisions?
Time series analysis allows businesses to make informed decisions by identifying patterns, trends, and seasonal shifts in their data over time. By studying historical data, companies gain the ability to anticipate future outcomes, which plays a key role in planning and managing resources effectively.
For instance, businesses can use it to project sales trends, fine-tune inventory levels, and handle financial risks with greater confidence. Tools like Looker AI take this a step further, offering enhanced precision in time series analysis, empowering organizations to craft data-based strategies that lead to smarter decisions.
What are the main methods used in time series forecasting, and how are they different?
Time series forecasting often relies on methods like ARIMA (AutoRegressive Integrated Moving Average), exponential smoothing, and seasonal decomposition to predict future values based on past data. Each approach brings its own strengths to the table.
ARIMA is particularly effective for non-stationary data. It uses a process called differencing to stabilize trends, making it easier to analyze and forecast. Exponential smoothing, on the other hand, places more weight on recent data points to highlight trends and seasonal patterns. Then there’s seasonal decomposition, which breaks the data into three distinct parts: trend, seasonality, and residuals. This makes it easier to spot hidden patterns within the data.
The choice of method depends on the data’s characteristics. For instance, ARIMA is best suited for stationary data, while exponential smoothing can naturally handle trends and seasonal changes without requiring extra transformations. And for more complex patterns, advanced machine learning techniques can step in, offering the flexibility to deal with a wide variety of forecasting challenges.
How does seasonality affect time series forecasts, and what methods can help improve accuracy?
Seasonality brings regular patterns or fluctuations to data - think holiday shopping surges or weather-driven trends. These patterns can heavily influence the accuracy of time series forecasts. If you ignore them, your predictions might miss critical cycles or trends, leading to less reliable outcomes.
To tackle this, you can apply methods like seasonal decomposition, which breaks the data into three parts: the overall trend, the seasonal effects, and the remaining random noise. For more advanced forecasting, tools like Seasonal ARIMA (SARIMA) or Exponential Smoothing (ETS) are great options. These models are designed to account for seasonal patterns, ensuring your forecasts align more closely with how the data behaves over time.
