The four primary methods are Descriptive Analysis, Diagnostic Analysis, Predictive Analysis, and Prescriptive Analysis. Each method supports different stages of business decision-making.
Most organizations begin with descriptive analysis to understand historical performance before implementing predictive and prescriptive analytics.
Descriptive analysis explains what has already happened, while predictive analysis forecasts future outcomes using historical data and statistical models.
Healthcare, banking, retail, manufacturing, logistics, education, insurance, telecommunications, marketing, and e-commerce all use data analytics extensively.
Basic analytics can be performed without coding using business intelligence tools, while advanced analytics typically requires knowledge of SQL, Python, or R.
The implementation timeline depends on project size, data complexity, integrations, and reporting requirements, typically ranging from a few weeks to several months.
