Scaling the Team from Startup to Enterprise

The size of your organization has a significant impact on how many people you should have on your data team and what roles are essential. The size of the team and the roles required will vary based on factors like the complexity of data needs, the industry you’re in, the amount of data you handle, and the scope of data-driven initiatives. Here’s how the size of your organization can affect your data team composition:

Small Organization:

In a small organization, resources may be limited, and there might be a need for team members to wear multiple hats. The emphasis is often on versatility and efficiency. The key roles in a small data team will often be more fluid and have a large amount of overlap, but will commonly include:

1. Data Generalist: Individuals who can handle a wide range of data-related tasks, from data collection and cleaning to analysis and visualization.
2. Data Analyst: Someone who can not only analyze data, but also create meaningful reports and dashboards for decision-making.
3. Data Engineer: One or two data engineers who can build and maintain the necessary data pipelines and infrastructure.

Medium-Sized Organization:

As the organization grows, so does the complexity of data needs. Data projects will grow to include a wider variety of data sources, more complicated and stringent business rules, and have more varied consumers downstream of the data team. Medium-sized organizations may have more than one data project they are pursuing, but will often still develop them in sequence using a single data team.

With medium-sized organizations there’s a bit more room for specialization in roles:

1. Data Analysts: More specialized analysts might focus on different areas such as sales, marketing, or operations.
2. Data Engineer: The team might include more data engineers to handle larger datasets and more complex data pipelines.
3. Data Scientist: A data scientist can help the data team to implement predictive analytics and develop machine learning models.
4. Business Analyst: A business analyst can be crucial to bridging the gap between the technical team and other departments.

Large Organization:

Larger organizations will more often than not have multiple large data projects running simultaneously and as such will require multiple data teams. In larger organizations, data needs become highly specialized, and there’s room for a more diverse range of roles:

1. Data Analysts/Scientists: Several analysts and data scientists, each specializing in different domains or types of analysis.
2. Data Engineers: A team of data engineers handling various aspects of data pipeline architecture, maintenance, and optimization.
3. Machine Learning Engineers: Specialized individuals to focus on operationalizing machine learning models.
4. Data Architects: A dedicated team to design and manage the overall data architecture.
5. Data Governance Manager: A dedicated role for data governance might be necessary as data compliance and security become more complex.
6. Data Visualization Specialists: Individuals who specialize in turning data into actionable insights through compelling visualizations.
7. Data Operations Managers: With multiple larger teams, management becomes more critical to ensure coordination and efficiency.

Remember, the key roles in a data team listed above are not exhaustive, and titles might vary from organization to organization. Also, it’s important to note that even in a small organization, you can start with a lean data team and gradually expand roles as data becomes more central to your operations. Always align your team structure with your organization’s specific needs, goals, and available resources.


In summary, building a data team is a strategic investment that can yield invaluable insights and competitive advantages for any organization. By assembling specialized key roles in a data team, businesses can effectively leverage data to make data-driven decisions, solve complex problems, and drive growth. As the field of data and analytics continues to evolve, companies must adapt their data teams to incorporate emerging technologies and methodologies, staying at the forefront of the data revolution. With the right data team in place, organizations can unlock the full potential of their data and propel themselves toward their goals. Read more about CTAC’s data solutions here:
