6 Steps of Data Science Lifecycle

Data Science


In today’s data-driven world, the demand for skilled data scientists has reached unprecedented heights. With businesses seeking actionable insights from vast amounts of data, the role of a data scientist has become indispensable. If you’re aspiring to embark on a rewarding career in data science, understanding the Data Science Lifecycle is crucial. In this comprehensive guide, we’ll delve into the six essential steps of the Data Science Lifecycle and explore the significance of quality education, such as the Data Science Training offered by Kelly Technologies in Hyderabad.

Problem Definition

The first and arguably most crucial step in the Data Science Lifecycle is defining the problem at hand. This involves understanding the business context, identifying the objectives, and framing the problem in a way that data can provide meaningful insights. It’s essential to collaborate closely with stakeholders to ensure alignment between business goals and data science objectives.

Data Collection

Once the problem is defined, the next step is collecting relevant data. This involves identifying potential data sources, gathering raw data, and assessing its quality. In this phase, data scientists at Kelly Technologies in Hyderabad are equipped with the skills to handle various types of data, including structured and unstructured data, from diverse sources. The Data Science Training in Hyderabad program by Kelly Technologies can help you grasp an in-depth knowledge of the data analytical industry landscape.

Data Cleaning and Preprocessing

Raw data is often messy and may contain inconsistencies, missing values, or outliers. Data cleaning and preprocessing involve transforming raw data into a usable format. This step is critical for ensuring the accuracy and reliability of the analysis. Kelly Technologies’ Data Science Training in Hyderabad emphasizes hands-on experience in data cleaning techniques to prepare aspiring data scientists for real-world challenges.

Exploratory Data Analysis (EDA)

Exploratory Data Analysis is the phase where data scientists explore and visualize the data to gain insights. This step helps in identifying patterns, trends, and relationships within the data. EDA is a powerful tool for generating hypotheses and guiding the selection of appropriate modeling techniques. Students at Kelly Technologies benefit from a practical approach to EDA, enhancing their ability to make informed decisions.


Modeling is the heart of the Data Science Lifecycle, where statistical and machine learning models are applied to the prepared data. Kelly Technologies’ Data Science Training in Hyderabad covers a wide array of modeling techniques, ensuring students are well-versed in regression, classification, clustering, and other advanced methods. Rigorous training in modeling equips aspiring data scientists with the skills to develop accurate and effective models.

Deployment and Communication

The final step involves deploying the data science solution and communicating the findings to stakeholders. Effective communication is essential for ensuring that the insights gained are understood and actionable. Kelly Technologies focuses on enhancing students’ communication skills, preparing them to convey complex findings in a clear and concise manner.


Embarking on a career in data science requires a solid understanding of the Data Science Lifecycle. The six steps – Problem Definition, Data Collection, Data Cleaning and Preprocessing, Exploratory Data Analysis, Modeling, and Deployment – form the foundation of a successful data science project. For individuals seeking quality education in data science, Kelly Technologies in Hyderabad stands out as a leading provider of comprehensive and hands-on Data Science Training. With a commitment to excellence, Kelly Technologies empowers aspiring data scientists to navigate the complexities of the field and make meaningful contributions to the world of data-driven decision-making.
