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.
Project portfolio management (PPM) is a systematic approach to selecting and managing a collection of projects aligned with organizational objectives. That is a business process of managing multiple projects which can be identified, prioritized, and managed within the organization. PPM helps organizations optimize their investments by allocating resources efficiently across all initiatives.

At the same time, Limited Partners comprise employees of the LP, some of the board members, and other investors like Reid Hoffman’s charitable foundation, Khosla Ventures, and Microsoft, the leading investor in the LP.
Airbnb follows a holacracy model, or a sort of flat organizational structure, where teams are organized for projects, to move quickly and iterate fast, thus keeping a lean and flexible approach. Airbnb also moved to a hybrid model where employees can work from anywhere and meet on a quarterly basis to plan ahead, and connect to each other.
The Amazon organizational structure is predominantly hierarchical with elements of function-based structure and geographic divisions. While Amazon started as a lean, flat organization in its early years, it transitioned into a hierarchical organization with its jobs and functions clearly defined as it scaled.
The Coca-Cola Company has a somewhat complex matrix organizational structure with geographic divisions, product divisions, business-type units, and functional groups.
Costco has a matrix organizational structure, which can simply be defined as any structure that combines two or more different types. In this case, a predominant functional structure exists with a more secondary divisional structure.
Costco’s geographic divisions reflect its strong presence in the United States combined with its expanding global presence. There are six divisions in the country alone to reflect its standing as the source of most company revenue.
Compared to competitor Walmart, for example, Costco takes more a decentralized approach to management, decision-making, and autonomy. This allows the company’s stores and divisions to more flexibly respond to local market conditions.

The company utilizes a flat organizational structure in combination with corporate function-based teams and product-based or geographic divisions. The flat organization structure is organized around the leadership of Mark Zuckerberg, and the key executives around him. On the other hand, the function-based teams are based on the main corporate functions (like HR, product management, investor relations, and so on).
