A business's objectives β whether growth, innovation, cost leadership or excellent service β are delivered through many factors. Organisational structure is one of them, and an important one, but its importance relative to other factors depends on the firm's situation.
The case that structure is the most important factor. Structure determines how work is divided, coordinated and controlled, and how quickly the firm can decide and act. A structure that fits the objectives makes everything else easier: a flexible, decentralised structure speeds innovation; a formal, centralised one delivers control and consistency. Crucially, a mismatched structure can sabotage even a sound strategy β a rigid hierarchy can strangle an innovative firm, while a loose structure can leave a cost-focused firm without control. Because structure shapes communication, motivation (through delegation and intrapreneurship) and the ability to scale, it can be the factor that decides whether good intentions translate into results.
The case that other factors can matter more. First, leadership and management quality can outweigh structure: capable managers can make an imperfect structure work, while poor ones fail even with a 'correct' structure. Second, finance is often decisive β without funds, a firm cannot pursue growth or innovation whatever its structure. Third, the workforce (skills, motivation, culture) determines whether delegated authority and intrapreneurship actually produce results. Fourth, external factors β competition, the economy, technology, regulation β can determine success or failure regardless of internal design. A perfectly structured firm can still miss its objectives in a hostile market.
Weighing it up (criterion). The importance of structure depends on how dependent the objective is on coordination, speed and the way people are organised, and on whether other factors are already strong. For objectives like rapid growth, innovation or efficient large-scale operations β where coordination and the alignment of structure with strategy are central β structure is often among the most important factors. For objectives constrained mainly by finance, market conditions or leadership quality, those factors dominate.
Judgement. Organisational structure is a necessary but rarely sufficient factor: it is most important when the objective hinges on how the firm organises and coordinates its people, and when other resources are already in place β but it cannot guarantee success on its own. The most defensible conclusion is that structure is a key enabling factor whose importance rises the more an objective depends on coordination, flexibility and the alignment of structure with strategy; for most firms, however, leadership, finance, the workforce and the external environment are at least as important, so structure is best seen as one critical factor among several rather than the single most important one in every case.
