In this digital age with vast amount of data (also called as big data), organisations in almost every domain are focused on exploiting data for many reasons. Some of them are: effective decision making, competitive advantage, market growth predictions etc. Extensive investments in business infrastructure improved the ability to collect data throughout the enterprise. Virtually every aspect of business is now open to data collection and often even instrumented for data collection for optimum functions in operations, manufacturing, supply- chain management, customer behavior, marketing campaign performance, workflow procedures, and so on. At the same time, information is now widely available on external events such as market trends, industry news, and competitors’ movements. Massachusetts Institute of Technology (MIT) from USA did a study on the data driven decision making and they found data-driven decision making environments had 4% higher productivity and 6% higher profits than other businesses did. http://searchbusinessanalytics.techtarget. com/news/2240035852/MIT-study-Data-driven- decisions-mean-higher-productivity-profits Data analytics is a process Data analytics or data analysis is a process, meaning we need to follow certain rules and steps and make our decision accordingly. In the figure 1, I tried to summarize the broad steps need to follow to make use of data. In each phase, we need to check certain key aspects regarding data and finally make decision which need to feed into the questions we are asking before any data analysis. Figure 2: Flow diagram of different phases of (big) data analytics and finaly decision making process. This outcome will again feedback into the initial process which is questions we are asking before we collect our data.
