Why is Quality Assurance the Backbone of Data Analytics
Written By: Pavithra Desikan

Data analytics has become an essential part of business operations, providing insights that drive informed decision-making. However, the value of these insights depends on the quality of the data used in the analysis. That’s where quality assurance (QA) comes in – it’s the backbone of data analytics. Here are five reasons why QA is essential to the success of the data workplace. 


Quality Data, Quality Results: How QA Ensures Accuracy in Data Analysis 

High-quality data is indispensable for ensuring accurate, consistent, and complete data, to make informed decisions and to leverage technologies like AI and machine learning. Implementing rigorous procedures to verify and clean data, along with establishing robust storage and formatting standards, is key to achieving data quality. Effective data quality management plays a pivotal role in the overall data management process, enabling confident decision-making and maximizing the benefits of data-driven technologies.  


According to Alafia Yusuf Fidvi, Project Manager at Systech, We faced a scenario where the client needed a rapid data migration of one million records. The Systech QA team worked closely with the client to develop a distinctive solution. By implementing this innovative approach, we successfully minimized the migration time to a few minutes, exceeding the client’s expectations.” 


Ensuring Data Consistency: The Importance of QA in Data Integration 

In today’s data-driven environment, businesses often have to combine data from various sources to gain a comprehensive view of their operations. However, integrating data from different sources can be challenging due to variations in formats, structures, and quality. QA ensures data consistency by identifying and resolving any inconsistencies, enabling businesses to analyze and interpret the data more effectively. 


Quoting Mukundan Kalyanaraman, QA Manager at Systech, “In a project last year, we developed of a unique automated testing system that resulted in time savings, improved testing outcomes, and optimized data quantity and quality. Moreover, it notably reduced the personnel required for validation and verification processes.” 


Preventing Costly Errors: The Role of QA in Data Security and Privacy 

In addition to ensuring data accuracy and consistency, QA also plays a critical role in data security and privacy. With the increasing threat of cyberattacks and data breaches, it’s essential to safeguard sensitive data against unauthorized access and malicious attacks. QA helps ensure data security and privacy by identifying and addressing potential vulnerabilities in data collection, storage, and analysis. 


As stated by Ramakrishnan Jayachandiran, Senior QA Lead at Systech,“The Systech QA team adheres to rigorous risk mitigation protocols to proactively combat unauthorized access incidents. These protocols include multi-factor authentications, regular security patches, and the implementation of supplementary security features. By staying proactive and vigilant against potential threats, QA strengthens the safeguarding of invaluable client data and system.” 


Achieving Compliance: How QA Helps Meet Regulatory Requirements in Data Analytics 

Many industries, such as finance, healthcare, and government, have strict regulatory requirements governing data collection, storage, and analysis. Failure to comply with these regulations can result in severe legal and financial penalties. QA helps businesses meet regulatory requirements by ensuring that data analytics processes and results adhere to industry standards and guidelines.  


Mukundan Kalyanaraman further emphasizes, “At Systech, our QA scope commences from the early stages of development. We ensure the QA testers collaborate extensively with developers to seamlessly integrate test cases into the project’s scope.” 


To wrap up, the significance of QA in data analytics cannot be overstated. They are instrumental in driving business success through data analytics. By ensuring the precision, coherence, and security of data, QA empowers businesses to extract valuable insights and make well-informed decisions. This instils confidence in the reliability and usability of data analysis results, and enables data-driven decision-making with conviction. QA acts as a vigilant guardian, constantly identifying and rectifying potential data quality issues, ensuring the continuous optimization of data analytics processes.
