4 D’s in Data: Analytics, Strategy, Engineering, and Science

The power of data strategies from data-driven teams and the 4 D’s in the information era: Analytics, Strategy, Engineering, and Science.

In a hyper-connected world, where new information is shared instantly, data-driven decision-making is no longer a differentiator, but a necessity.

In this scenario, the formation of multidisciplinary data-specialized teams, known as data-driven teams, plays a vital role in empowering collaborators. Among the various disciplines that comprise these teams, four key solutions stand out: Data Analytics, Data Strategy, Data Engineering, and Data Science, often referred to as the 4 D’s.

In this article, we will explore how these four fundamental disciplines in data-driven teams are structured and how effective collaboration among these areas plays an essential role in successfully creating and applying data-driven strategies within organizations.

Data Driven

Before discussing the fundamental roles of the 4 D’s, we need to understand the origins of the data-driven culture. For many years, decisions made by organizational management were based on assumptions. When these decisions worked, leaders believed they could replicate the strategy, and the opposite was also true. However, decision-making based on assumptions creates uncertainty, as assumptions lack solid foundations. What works once may fail the next time, even if the action is similar.

Thus, an urgent need arises: managing information. By adopting a data-driven culture, companies are better equipped to make informed decisions, mitigate risks, optimize processes, improve operational efficiency, and ultimately achieve a competitive advantage. It’s a strategic movement reflecting the need to adapt to a constantly changing world, where data is a valuable asset driving progress.

In this sense, established companies have managed to separate different sectors that, collectively, extract, transform, expose, generate insights, and even predict future movements based on data within the data-driven ecosystem.

Data Analytics

Data analysis, commonly referred to as data analytics, is a fundamental branch for the emergence of the data-driven culture. In companies with specialized areas, such as Cadastra, the data analytics professional performs the ETL (extract, transform, load) process and simplifies data visualization for decision-makers, who may be colleagues or clients, using tools like Google Analytics, Power BI, Looker Studio, and Google Sheets.

Data Strategy

For data strategists, the task is different. Yes, there are overlaps between the roles of analysts and strategists, but the key distinction lies in using the collected data to create business plans that optimize client outcomes. Thus, analyses such as custom profile, market basket, event correlation, and price elasticity are daily tools for strategists.

Additionally, these professionals may work directly on the client’s platform. Every click is considered a digital footprint, an action that can help understand the user experience. By using tools like Google Tag Manager (GTM), they can create parameters to measure consumer actions on websites, aiming to optimize customer experiences and boost results.

Data Engineering

In most cases, the role of a data engineer is to ensure that all processes for the other D’s function correctly.

One of the crucial responsibilities of this professional involves data storage. To achieve this, they implement data collection systems through databases, APIs, and servers. These systems must be secure and scalable, complying with standards that protect user information. Analysts rely on these data storage platforms for transformations, making it essential for the databases to always be updated and correctly configured for extractions.

Data engineers can use various tools depending on the client’s needs. These include database management platforms like PostgreSQL and MySQL, data processing systems such as Hadoop and Spark, or even programming languages like Python.

Data Science

Unlike other professionals, the expertise of data scientists spans various fields, such as statistics, computer science, and mathematics. Their work often involves complex activities like using machine learning models, whose primary goal is to create algorithms that automate processes, understand data patterns, and predict outcomes. In this way, the technical knowledge of data science can help an area apply actions aimed at improving strategic decision-making at the business level.

The complementarity of the 4 D’s

As previously mentioned, many companies fail by expecting a single employee to handle multiple roles: building infrastructure for data management using programming languages, performing ETL processes, strategically analyzing data for business insights, and even creating predictive models using statistical concepts.

To illustrate, think of the real estate business. It requires real estate agents to sell properties, engineers to map processes, architects to design floor plans, and builders to construct homes. Similarly, it is unrealistic to expect one professional to excel in all these areas. The same applies to a data-driven environment.

At Cadastra, we have established that each of the D’s (Analytics, Strategy, Engineering, and Science) has a specific role, and together they help understand the business and optimize results. For example, the engineer is responsible for creating data structures and storage systems; the analyst for extraction, transformation, and loading; the strategist for developing methodologies and business analyses; and the scientist for using machine learning models to predict outputs from collected data. This specialization allows each professional to focus on their area and strive for excellence.

Final considerations

It is clear that each professional within the four D’s has a specific role in the business. For complementarity to succeed, clear roles and a data-driven environment among collaborators—where everyone understands their responsibilities—are essential. This way of working becomes organized and symbiotic, guiding each person to their function.

Of course, many professionals possess expertise that extends beyond their primary responsibilities. Thus, fostering an environment of collaboration and goodwill is crucial for improving results.
