This paper examines whether functional strategies — spanning marketing, finance, operations, human resources, and R&D — can be formulated independently or must remain interdependent with higher-level business unit and corporate strategies. Drawing on a hierarchical model of strategy, the paper argues that functional strategies exist to serve broader organizational goals and cannot operate in isolation. It further explores how a firm's organizational structure influences the degree of integration among functional areas, noting that cross-departmental teams foster greater strategic coherence while strictly segmented structures may allow each function to develop a more autonomous approach.
Functional or organizational-level strategies must ultimately relate to the strategic decisions made by the firm regarding macro-level business processes and the overall organizational value chain. "Functional level strategies in marketing, finance, operations, human resources, and R&D involve the development and coordination of resources through which business unit level strategies can be executed efficiently and effectively" (Hierarchical levels of strategy, 2010, Quick MBA). They are meant to serve business unit strategies and overall corporate strategies, rather than exist independently. Functional strategies do not have a purpose in and of themselves; rather, they are tools to reach a higher goal.
Because of their interdependence with wider, long-term business unit level and corporate level strategies, functional strategies should be integrated collectively rather than viewed in an independent, stand-alone fashion. Functional strategies are by definition purposeful and designed to move the firm forward in a tactical fashion. They require different units working together to achieve a common goal: simply having a strong marketing strategy is useless if it is not connected to an R&D strategy that provides consumers with a high-quality product; an ambitious R&D project is merely a dream if it is not also financially feasible.
Functional strategies are important because, as noted, "once the higher-level strategy is developed, the functional units translate it into discrete action plans that each department or division must accomplish for the strategy to succeed" (Hierarchical levels of strategy, 2010, Quick MBA). Even though they are interdependent, a wider corporate strategy cannot succeed if it is not served well by a functional strategy. Yet for functional strategies to be truly functional and to serve the larger purposes of the organization, all strategies must be complementary — otherwise, different departments may compete with one another and even subvert each other's objectives.
If a marketing department views its functions as more important than the technological development of the products it is promoting, its internal strategy may undermine rather than support the larger organization. A lack of perceived and real interdependence between functional strategies can result in an ineffective use of resources.
