Predictive analytics is a form of advanced data analytics. It uses techniques such as data mining, modeling, statistics, machine learning (ML), and artificial intelligence (AI) to analyze current and historical facts and to forecast events.
A predictive analytics model is a mathematical model that data science engineers build to answer questions related to "events of interest" such as the prediction of the occurrence of an event in the future.
Different types of models exist (statistical, machine learning) can be used for predictive analytics projects.
The process of creating a predictive analytics model includes running algorithms, such as "time series" algorithms for making time-based predictions and "association" algorithms for identifying recurring patterns in large transactional data sets.
Predictive analytics projects vary widely, based on the business objectives for using data insights about the future. For example, companies in many industries, such as financial services and energy, predictive maintenance, use predictive analytics solutions for everything from forecasting product demand to estimating equipment maintenance needs.
Whatever the project type, the core reason that organizations use predictive analytics is to enable more proactive behavior.
For instance, organizations could use insights from predictive analytics to prevent problems that might cause disruption or compromise profitability. Or they could use insights to take advantage of emerging trends and events that may give them competitive advantage.
Here's an example of how a business could use predictive analytics to improve its everyday business operations:
A beverage manufacturer's data science team creates a predictive analytics model to determine when trucks are most likely to arrive at the warehouse to pick up a shipment. Knowing when products should be packaged and ready for loading creates more operational efficiency.
The manufacturer might also provide information about ideal truck arrival times and estimated wait times to its logistics partners, to help improve efficiency further in the supply chain.
Diagnostic analytics, prescriptive analytics, and operational analytics are other examples of advanced analytics methods. A brief explanation of each follows.
Diagnostic analytics
Diagnostic analytics is a reactive form of data analysis. This form of analytics is based on descriptive analytics, an analytics process that examines data to determine changes that occur in a specified period.
To perform diagnostic analytics, analysts use a combination of techniques, such as data mining and data correlation, to understand why an event, trend, or relationship occurred.
Organizations often use diagnostic analytics tools and processes to identify issues undermining device or system performance. Such tools also help cybersecurity teams to identify the root causes of data breaches.
Prescriptive analytics
This emerging area of advanced analytics, which includes the use of predictive analytics, is meant to help organizations answer two questions: "What should we do next? And then, what will happen?"
Prescriptive analytics goes beyond making predictions by suggesting actions to take and the potential outcomes of those actions. Many companies in the energy sector use prescriptive analytics to help improve operational safety. Self-driving cars also use prescriptive analytics.
Operational analytics
Operational analytics, sometimes referred to as continuous analytics, can be used to improve an organization's operations. While not a new discipline, it's a rapidly evolving area of analytics that is becoming more prognostic.
As organizations become more digitized, they're able to expand their use of operational analytics. That's because they now can access more of their data, including from the cloud, more easily and in real time.
Using advanced tools, they can analyze the data quickly to get insights that they can put into action almost immediately—or, with some solutions, even automatically.
An example of operational analytics is collecting and analyzing various metrics from a service delivery chain, such as network, application performance, and associated dependency metrics—proactively from multiple vantage points to quickly troubleshoot network services issues or optimize web application experiences for the distributed workforce.
Today's organizations are adopting tools to increase visibility into what's happening in their networks at any time. They use the resulting insights to optimize digital experiences for their employees and customers.
They're also investing in advanced solutions that help them see into external networks that they don’t own or control, such as the internet.
This extended visibility helps them further assure service delivery. In fact, it's becoming essential as organizations accelerate their adoption of software-as-a-service (SaaS), internet, and cloud solutions to support hybrid work strategies, increase business agility, and drive digital innovation.
In short, enterprises have more access to more telemetry from more sources than ever before that they can analyze, including with predictive analytics solutions.
Predictive analytics models also can build up enough intelligence to understand patterns around the data, to forecast issues for an organization to avoid or take advantage of. These models get "smarter" over time by learning from the data that they receive.
With the strategic and timely application of predictive analytics insights in the network, organizations will be in a position to drive better IT outcomes, by creating more performative and, ideally, self-correcting network environments where users receive services and access applications.
Using the internet for networking is more critical than ever to organizations. In the past, organizations relied on managed networks. That made sense when most of the workforce was located on site. Now, workforces are more distributed, with remote and hybrid users engaged in "anytime, anywhere" working.
Many organizations are now turning to a software-defined wide-area networking (SD-WAN) approach to support their distributed teams' networking needs. SD-WAN solutions provide advanced analytics, such as network and performance telemetry collected from edge devices, when combined with continuous monitoring and automation, can facilitate intelligent routing and WAN optimization across the network.
SD-WAN helps organizations ensure that their users can get optimal speeds and performance for services, applications and connections across the network.
Predictive analytics can benefit and further augment SD-WAN capabilities and refine the dynamic enforcement of application service-level agreements (SLAs).
For example, an employee working from a remote location is connecting over a link that while providing connectivity, is exhibiting indications that it is becoming overloaded, which if allowed to continue would result in a SLA breach. Instead before that connection reaches that point, the connection is established over a healthy path reducing the impact to the users experience.
