Customer departmentalization groups a company’s people and units by the customers they serve (consumers, small businesses, large corporations, professionals) rather than by function, product or region. The idea goes back to Luther Gulick, who in 1937 listed four bases for grouping work: purpose, process, place, and the persons or things dealt with or served. Its promise is one coherent face to each customer group; its cost is duplicated specialists.
Split customers where needs really differ, for example consumers vs businesses, or do-it-yourself homeowners vs professional contractors.
02
Give each group its own unit
Each unit gathers the sales, service and often product people who work with that group, so one team owns the relationship end to end.
03
Share what must stay common
Technology, risk, supply chain and brand usually remain central functions that serve every customer unit, which avoids building everything several times.
04
Measure by customer
Report revenue, profit and satisfaction per customer group, so leaders see which relationships make money.
Where you see it today
Banks organized by client
JPMorgan Chase reports three segments built around clients: Consumer & Community Banking for consumers, and the Commercial & Investment Bank and Asset & Wealth Management for wholesale clients. Since a 2024 reorganization, Commercial Banking is a client coverage segment inside the Commercial & Investment Bank, which reports revenue by client coverage segment.
Retail split by DIY and Pro
Home Depot describes two primary customer groups, consumers (do-it-yourself and do-it-for-me) and professionals, with dedicated Pro teams in stores and separate distribution businesses such as SRS for specialty trades and HD Supply for maintenance buyers.
AI tools per customer group
In January 2026 Home Depot expanded its Magic Apron assistant for homeowners and launched AI-powered product list builders for pros, built on Google Cloud’s Gemini models. The customer split now shapes the software as well as the org chart.
Segments inside segments
Within Asset & Wealth Management, JPMorgan reports assets by client segment (Private Banking, Global Institutional and Global Funds) and in 2025 moved some client assets between them to match where they are invested. Customer structures are revised as clients change.

How to use it
Use it when customer groups differ in what they buy, how they buy and what service they need, not just in size.
Write down which specialists each customer unit gets and which stay shared, before you redraw the chart.
Decide who owns a customer who belongs to two groups, such as a business owner who is also a retail client.
Give each customer unit its own profit and satisfaction numbers, or the structure will drift back to function.
Review the groups every year or two; regroup when clients change, as banks and retailers regularly do.
The Business Engineer lens
AI assistants let a company give each customer group tailored service without hiring a full team per segment, which lowers the cost Gulick warned about. The Business Engineer’s view: the customer split increasingly lives in software and data, and the org chart follows it.
Grouping units and people by the customers they serve, such as consumers vs businesses, instead of by function, product or region.
Who first described it?
Luther Gulick's 1937 essay on the theory of organization listed the persons or things served as one of four bases for grouping work, next to purpose, process and place.
What are its advantages and disadvantages?
Gulick noted it simplifies the customer's contact with the organization and builds skill in serving one group; its costs are lost specialization and overlap, because people belong to several groups.
What is an example of customer departmentalization?
JPMorgan Chase separates Consumer & Community Banking from its wholesale businesses, and Home Depot runs dedicated teams and businesses for professional customers alongside its consumer stores.

In the ever-evolving landscape of businessmanagement and organizational design, the concept of customer departmentalization holds a central place. It is a strategic approach to organizing a company’s structure around distinct customer groups or segments, with the primary goal of tailoring products, services, and marketing strategies to meet the unique needs and preferences of each customer category.
Introduction to Customer Departmentalization
Customer departmentalization, also known as customer-centric departmentalization, is a method of organizing a business based on the characteristics and preferences of different customer groups. Rather than having a one-size-fits-all approach, organizations employing customer departmentalization create dedicated departments or teams for specific customer segments. These segments can be defined by various factors, such as demographics, behaviors, purchasing habits, or industry-specific needs.

In a functional organizational structure, groups and teams are organized based on function. Therefore, this organization follows a top-down structure, where most decision flows from top management to bottom. Thus, the bottom of the organization mostly follows the strategy detailed by the top of the organization.
In a flat organizational structure, there is little to no middle management between employees and executives. Therefore it reduces the space between employees and executives to enable an effective communication flow within the organization, thus being faster and leaner.
