Big Data Analytics Process
Big Data Analytics Process Gaining business insight from large amounts of data requires multiple steps:
Identify Business Objective –
The initial step to effectively using big data analytics for business is identifying your desired goals, such as improving sales, increasing customer experience and operational efficiencies or risk mitigation measures. Common goals may include these.
Data Collection –
Gather all relevant structured and unstructured information from all available sources such as CRM systems, social media pages, documents or sensors in order to collect structured and unstructured data that is both structured and unstructured in nature. A larger dataset allows more insight to be extracted;
Data Pre-processing –
This involves data cleansing to remove errors, inconsistencies and duplicate information from structured and unstructured datasets respectively. Structured information should be organized while unstructured text/image data may require processing through Natural Language Processing/Computer Vision techniques.
Data Integration –
Integrating preprocessed datasets provides a more complete picture and allows for analysis to occur quickly and efficiently.
Exploratory Analysis –
Initial exploration of cleaned, integrated data should reveal any interesting trends, correlations or questions which will provide direction for further steps in analysis and decision-making.
Advanced Analytics –
To provide valuable insight, sophisticated techniques like predictive modeling, machine learning, neural networks clustering and decision trees may be applied based on a problem statement to gain deeper insight.
Visualization –
Analytics results are communicated easily to business teams via reports, dashboards, graphs or charts for easy understanding and application of insights gained.
Implement Insights –
Once insights have been identified and action plans drawn up for them to implement across business functions such as marketing, operations and finance in order to drive growth and productivity, implementation can finally occur.
Process Improvement Requires Cross-Functional Collaboration Between IT teams managing data infrastructure and business teams setting objectives and applying insights. Overtime, ongoing iteration and monitoring ensure that both processes and results continue to evolve over time.
Big Data Analytics Techniques
A variety of advanced techniques are utilized for the analysis and interpretation of big data to yield actionable insights from it. Here are a few such key strategies:
