How to do prescriptive analytics?

Technology has an ability to forecast the future of enterprise and predict the chances of failure or success of any business organisation. Earlier, people have to rely on small samples of data, simple questions and other ways to collect useful information. But now, everything is possible. All the data collected by any organisation has to go somewhere. Lots of them make their ways to data lakes or some other type of data storage.

In today?s world, data collected by the organisation wouldn?t be used for quick gains but can be used in the future that the organisation is looking for. That is to make the best possible decisions. All those data are being utilised by the business organisation to describe current trends, predict whats is going around or what is going to happen next and most important, to prescribe the proper action that the organisation should take to ensure success in the best possible manner. This is only possible through prescriptive analytics. Prescriptive analytics is the last stage of data analytics and it requires lots of capital and human capabilities to handle and process the analysis. If there is any kind of uncertainty in any business organisation future, they can use prescriptive analytics to eliminate that problem.

Prescriptive analytics is the third and final stage of data analytics. Prescriptive analytics draw predictions about the future and refer a complete description of the present scenario in order to determine the best possible action to eliminate the cause of the problem. The centre of prescriptive analytics relies on the idea of optimisation. The process of optimisation considers every small factor that is required to draw a better prescription model. Prescriptive analytics finds a large application in supply chain management, Operation management and Human resources management.

Prescriptive analytics not only predict possible outcomes but also state the reason for their occurrence and time of occurrence. It also suggests the decisions options for the possible forecast. The term prescriptive analytics was first termed by IBM in their analytics magazines. The entire article was divided into three types of business analytics and how IBM conceives of prescriptive analytics.

  • Optimisation, or how to achieve the best output.
  • Stochastic optimisation, or how to achieve the best output and make better decisions by considering the uncertainty of real-time data.
