Data Analysts provide business solutions to organisations by applying statistical/mathematical rigour to large data. In industry parlance they are on the ‘Predictive Analytics’ part of the Analytics cycle providing inputs such as ‘What will happen next’, ‘What’s the best that can happen’, and ‘How best should it be done’.
A Data Analyst needs to fundamentally combine the skill sets of Maths, IT and Business knowledge. While good capabilities in Maths/Statistics is the necessary prerequisite to make a Data Analyst, a broad understanding of Business environment with some proficiency in IT are the sufficient prerequisites. Specific academic backgrounds are not prerequisites but a comfortable Quant orientation is desirable to be a Data Analyst.
Initial job roles would be part of an analytics team working as Statistical Analyst, Data Miner, Forecaster, Market Researcher, Operations Researcher and similar profiles. With career development, Data Analysts may focus towards specific domains such as Customer Intelligence, Risk Intelligence, and Supply Chain Intelligence. With further career progression they look to industry specialisations within the domains they gain expertise on such as Banking, Telecom, Insurance, Retail, etc. This is an exciting, very high potential career with good remuneration and a large gap between demand and supply catering both to the outsourced work in India and to growing use of analytics in domestic industry.
Business Analysts, with their core understanding of the organisations’ business, provide reports to various end users in the organisation for effective decision making. These reports are based on insights from summary statistics of the large data or insights developed by applying mathematical rigour on the data.
Business Analysts need to have good analytical capabilities to access, organise and report data. They need to have a good understanding of the organisation’s business and they should have the capability to understand business users’ requirements and accordingly provide insightful reports. Further they should have fundamental understanding of Dimensional Modeling including OLAP.
As organisations have more data, they want to use it to build competitive advantage. Business Analysts have the opportunity to be part of large teams that provide these insights. This ever expanding activity in the domestic and outsourced markets provides a big career opportunity for aspiring Business Analysts.
