When a company decides where it wants to go (strategy), it immediately faces a practical question: who does what, and who reports to whom? That answer is its organisational structure — the formal arrangement of roles, responsibilities, and reporting lines that converts strategy from a boardroom idea into daily action. Alfred Chandler's famous finding says it best: "Structure follows Strategy." Pick the wrong structure for your strategy and the whole execution machine jams.
The ICAI curriculum recognises five main structures you must know cold. A Simple/Entrepreneurial Structure suits a start-up like Rajesh & Co. Pvt. Ltd. — the founder calls every shot, it's fast but can't scale. A Functional Structure groups people by specialisation (Finance, Marketing, Operations) and works perfectly when a firm pursues a single business or low-cost strategy. As the firm diversifies into multiple products or geographies, it shifts to a Divisional Structure, where each division (say, Iyer Foods' Beverages Division vs. Snacks Division) runs almost like its own company with a P&L. When two dimensions matter equally — say, product AND geography — a Matrix Structure assigns dual reporting lines; Ms. Iyer reports both to the South Region Head and to the Product Manager. Powerful but notorious for role conflict. Finally, a Network/Virtual Structure keeps a lean core and outsources heavily — think of a fashion brand that designs in Mumbai, manufactures in Tirupur, and distributes through third-party logistics.
The exam-critical insight is strategic fit: a Cost Leadership strategy pairs best with a tight Functional Structure (centralised, standardised). A Differentiation strategy needs looser, decentralised Divisional or Matrix structures that allow creative teams to move fast. A Diversification strategy almost always demands a Divisional or SBU (Strategic Business Unit) structure. Remember SBUs — a cluster of related divisions grouped under one umbrella for strategic planning — because they appear frequently in 4-mark and 6-mark scenario questions. The examiner typically gives you a company profile and asks: which structure fits and why? Your answer must explicitly link the strategy type to the structural choice and call out the coordination mechanism (e.g., centralised support services in SBU structure).
