When is Big Data Enough?


In the world of artificial intelligence (AI), Big Data and data science, the crux of the matter has always been people. While AI has long been a subject of fascination and even fear, the real challenge lies in finding the right balance between human expertise and machine capabilities.

It’s time to shift the focus from the machines to the minds behind the data;

Imperfect Data, Sound Decisions

Sarah Catanzaro, a former head of data at Mattermark, raises a crucial point about the utility of imperfect data. She emphasizes that not all decisions require high-precision insights, and sometimes, quick and rough analysis can suffice. This perspective challenges the relentless pursuit of more and more data in the belief that it will always lead to better results.

Data Quality vs. Data Quantity

In the quest for AI advancements, we often overlook a fundamental truth: more data doesn’t always equate to better outcomes. What we truly need is a workforce well-equipped to interpret and leverage the data we already possess. As data scientist Elena Dyachkova points out, a significant portion of product analytics relies on “quick and dirty” assessments. However, making informed judgments in these situations demands a solid understanding of statistics.

The Human Element in Decision-Making

Vincent Dowling, a data scientist at Indeed.com, underscores the importance of experienced analysts in decision-making. Regardless of the volume of data, the expertise of those handling it holds more weight. Machines cannot compensate for the lack of human judgment and insight. The Guardian raises a critical question: What if machines make faster but worse decisions due to human abdication?

People in Control: Easier Said Than Done

While putting people in control of AI sounds logical, it’s a complex task in practice. AI is influenced by the data it’s fed and the algorithms it employs, all of which are guided by human inputs. The highly contextualized view of the world shapes AI’s outcomes. To label data accurately, experienced individuals who understand the data are essential.

The Wisdom of Business Understanding

A decade-old point made by Gartner analyst Svetlana Sicular still holds: Enterprises are filled with individuals who comprehend the intricacies of their businesses. They are best suited to ask the right questions of the company’s data. However, bridging the gap between business acumen and statistical knowledge remains a challenge.

The Challenge of Data Science Talent

While talent shortages in data science are often cited, perhaps the real deficit lies in fundamental skills like statistics, mathematics, and a deep understanding of a company’s operations. The roadblocks to AI and machine learning adoption are not solely about finding data science talent; it’s also about fostering a culture of data literacy and expertise.
