Taking a dive into deep data
Hermann Sidhu explains how analytics is revolutionizing the audit and facilitating the introduction of disruptive technologies such as artificial intelligence, machine learning, robotics and blockchain.
Audit is undergoing a data revolution. There has been rapid expansion in the types and volumes of data that companies produce, providing richer sources of information to be used when conducting an audit. Digital analytics tools are enabling industry professionals to look at businesses in a different way by analyzing these bigger data populations. This provides a deeper understanding of risk, performance and opportunities.
While data analytics has been used broadly for decades, limitations in computing power, connectivity and cybersecurity have made it challenging to obtain, process and interpret data in a meaningful and consistent way. Now, with the majority of transactions conducted electronically, powerful data analytics tools and techniques enable auditors to analyze more data points than ever before, which can enhance audit quality and confidence in the capital markets.
“The ability to analyze larger data sets enables auditors to better identify the risks of material misstatement, including risks of fraud.”
Such in-depth analysis of higher-risk transactions in banking might, for instance, allow the identification of an unusually high number of credit transactions that, in turn, might indicate errors in their processing, signaling a misstatement.
Audit analytics and risk assessments allow auditors to focus on higher-risk areas. At EY, as part of a global audit engagement, we developed a dashboard using the new analytical tools to help us identify higher- or lower-risk business areas across regions, as well as to what extent different countries or different entities were susceptible to corruption and regulatory issues. The findings were incorporated into the audit plan to strengthen the audit.
In the coming years, there will be significant use of enhanced analytical tools. Audit professionals will be delving deeper into a combined analysis of structured data, such as financial statements, and unstructured data, such as large volumes of client contracts. They will be able to provide extensive analysis and quality business insights.
Artificial intelligence (AI), machine learning, robotics and blockchain will also have a major impact on the profession. But these technologies all rely on the data. If you don’t have the ability to analyze data, you cannot do analytics, you cannot do machine learning, you cannot do robotics and you cannot do blockchain.
AI is expected to provide stronger and more useful tools for auditors to interrogate the data, find anomalies and improve techniques, all of which can lead to higher-quality audits. The real value of machine learning comes from having computers that, over time, understand what “normal” is to an organization and identify what is not.
Digital technology is disrupting the current landscape, giving audit professionals the tools to take a deep dive into data, enabling them to ask better questions and get better answers.
