Data science is a rapidly growing field that involves extracting insights and knowledge from data. It combines various techniques from mathematics, statistics, and computer science to make informed decisions and drive business value. One of the key frameworks used in data science is the data science lifecycle, which provides a systematic approach to solving problems and extracting insights from data.

The data science lifecycle consists of several stages, each with its own unique set of tasks and activities. These stages typically include problem identification, data collection, data preparation and cleaning, data analysis and model building, and model deployment and evaluation.

Let's consider an example to understand the data science lifecycle better. Suppose a retail company wants to improve its sales forecasting accuracy. In the problem identification stage, the company would identify the problem as improving sales forecasting accuracy. The next stage is data collection, where the company would gather historical sales data, customer data, and external factors such as economic indicators and seasonality data.

By following the data science lifecycle, companies can approach data-driven problem-solving in a structured manner, ensuring that no crucial steps are missed and the results are reliable and repeatable.
