Business Analytics

What does it take to be a Bussiness Analyst

The business analyst role is often seen as a communication bridge between IT and the business stakeholders. Business analysts must be great verbal and written communicators, tactful diplomats, problem solvers, thinkers and analysers - with the ability to engage with stakeholders to understand and respond to their needs in rapidly changing business environments. This can often involve dealing with very senior stakeholders and can often involve challenging and questioning to ensure that value for money is achieved from IT developments.
 
A business analyst does not need to have an IT background although it can help to have some basic understanding of how IT systems work. Some business analysts come from a technical or programming background but they will often come from within the business itself - having a detailed knowledge of the business domain can be equally useful.
Once the business goal of the analysis is determined, an analysis methodology is selected and data is acquired to support the analysis.  Data acquisition often involves extraction from one or more business systems, cleansing, and integration into a single repository such as a data warehouse or data mart.  The analysis is typically performed against a smaller sample set of data.  Analytic tools range from spreadsheets with statistical functions to complex data mining and predictive modeling applications.  As patterns and relationships in the data are uncovered, new questions are asked and the analytic process iterates until the business goal is met.  Deployment of predictive models involves scoring data records (typically in a database) and using the scores to optimize real-time decisions within applications and business processes.
