What Is Prescriptive Analytics?Prescriptive analytics answers the question “What should/can be done?” by using machine learning, modeling, simulation, heuristics, and other methods to predict outcomes and provide decision options. Building upon descriptive and predictive analytics, prescriptive analytics not only provides forecasting and predictions about future events, but what could make them happen. Using this information, analysts can test the impact of strategic decisions to optimize their decision-making processes.
Why Is Prescriptive Analytics Important?Building on the work of descriptive and predictive analytics, prescriptive analytics can benefit a business by helping them:
- Make informed, fact-based decisions by using real-time and forecasted data
- Understand the likelihood of certain outcomes the impact of decisions on those outcomes, and use it to plan what to do and how
- Save resources and boost efficiency by allowing AI to curate and process data into actionable scenarios
- Create reproducible and scalable processes to make decisions using near-time data
- Answer the most complex business questions such as demand forecasting, risk assessment, and what-if scenarios
How Prescriptive Analytics Works
Prescriptive analytics is the final step in business analytics and leverages the outcomes of several statistical methods and the power of AI. While descriptive analytics answers, “What has happened?” and predictive analytics answers, “What could happen?” prescriptive analytics answers, “What should we do?” and “How will our decisions affect future performance?” It gives analysts and decision makers the power to positively and confidently impact future outcomes through optimization models and iterative machine learning.
Prescriptive analytics can benefit any data-driven business and is highly utilized in fields where data is constantly changing and decisions can have wide-ranging impact.
- In healthcare, prescriptive analytics can help in both administration and patient care. A pharmaceutical company can use prescriptive analytics to reduce the costs of testing by finding the best subjects for a clinical trial, while a hospital might use it to provide attention to patients who need it most by seeing who has the highest risk of re-admission.
- In transportation, an airline can automatically adjust pricing and availability based on various factors including weather, demand, and oil prices.
- In publishing, an outlet can decide what to publish and if a piece will be popular based on search and social data for similar topics.
- In human resources, online training can be adjusted in real time based on an employee’s performance on each lesson.
