Data is extremely important in today’s digital-first world, as it has always been. Throughout its life cycle, it goes through a number of stages, including creation, testing, processing, consumption, and repurposing. The Data Analytics Lifecycle is a diagram that depicts these steps for professionals that are involved in data analytics projects. The phases of the Data Analytics Lifecycle are organized in a circular framework, which is referred to as the Data Analytics Lifecycle. Each stage has its own significance as well as its own peculiarities. In this article, we’ll go over the different data analytics lifecycle phases and discuss them one by one.

Why Data Analytics Lifecycle Is Essential

The data analytic lifecycle is intended for use with large amounts of big data and data science initiatives. The cycle is iterative in order to accurately represent the real project. To discuss the distinct requirements for analyzing the information on Big Data, a step–by–step methodology is required to organize the activities and tasks engaged with acquiring, processing, analyzing, and repurposing data. This methodology should be organized to address the distinctive requirements for analyzing the information on Big Data.

Organizations can use big data analytics to harness their data and use it to identify new opportunities as they grow. Smarter business decisions and operations result in higher cash flow and increased customer satisfaction as a result of this process. The data life cycle is concerned with making informed decisions; data analysis is concerned with the use of tools to transform information. The data life cycle is concerned with the phases that data goes through during its useful life, whereas analysis of data is the process of examining and interpreting information.

Importance of Data Analytics Lifecycle

The circular shape of the Data Analytics lifecycle directs data professionals to move in one direction with data analytics, either forward or backward. Professionals can discard the entire investigation and return to the starting phase to repeat the full analysis according to the lifecycle diagram.

While professionals discuss the data analytics lifecycle, there is currently no established structure for the aforementioned stages. It’s highly improbable that you’ll come across a tangible data analytics architecture that is universally followed by all data analysis certified experts. This uncertainty increases the likelihood of adding additional phases (if necessary) and omitting fundamental steps. Additionally, there is the option of working on multiple phases concurrently or bypassing a phase entirely.

Life Cycle Phases of Data Analytics

This tutorial discusses the data analytics lifecycle phases that are essential to each data analytics process and how to implement them. As a result, they are more likely to remain present throughout the lifecycle of most data analytics projects. 

Phase 1: Data Discovery and Formation

To begin, there must be a clear objective. When you reach the end of the data analytics lifecycle, you will have defined the purpose of your data and the methods by which you will achieve that aim. 

Phase 2: Data Preparation and Processing

In this stage, everything that has anything to do with data is brought together. Business requirements are given priority in phase 2, while information requirements receive equal attention. It is necessary to collect, process, and clean up all of the data accumulated before proceeding to the next phase.

Phase 3: Design a Model

After mapping out your business objectives and gathering a plethora of data (structured, unstructured, or semi-structured), it is time to develop a model that will help you reach your goals. This is known as data mining. Also included is the collaborative work required to identify and refine methodological approaches and workflows. 

Phase 4: Model Building

The development of data sets for testing, learning, and product components is the final phase in the data analytics architecture process. Construction and operation of the model created in the previous step are painstakingly carried out by the data analytics professionals.

Phase 5: Result Communication and Publication

The communication step begins with a collaborative effort with key stakeholders to evaluate if the project’s outcomes were a success or a disappointment. As part of its work, the project team is expected to identify and quantify the important findings of the study. 

Phase 6: Measuring of Effectiveness

As your data analytics lifecycle comes to a close, the next stage is to deliver a complete report to the stakeholders, including key results, coding, briefings, technical papers/documents, and other supporting materials. Additionally, in order to assess the efficiency of the study, the data is transferred from the sandbox to a live environment.

Data Analytics Lifecycle Example

Consider the case of a retail shop chain that wishes to maximize the revenue from its items by optimizing the prices of its products. With thousands of products spread across hundreds of locations, the shop chain presents a tremendously complex scenario. In order to achieve this goal, you must first identify the data you require, prepare it, and then go through the Data Analytics lifecycle process as described above.

Conclusion

There are a variety of talents that data analysts must possess in order to be effective in their employment, ranging from hard skills such as statistical modeling to soft skills such as excellent effective communication which is implemented in data analytics lifecycle phases. Although technical skills are important in establishing a successful analytics profession, having a solid mix of non-technical talents can help you reach new heights in your professional life.
