chapter 8OrganizingMcGraw-Hill/IrwinPrinciples of Management © 2008 The McGraw-Hill Companies, Inc., All Rights Reserved.Learning ObjectivesExplain what is meant by organization architecture.Explain the advantages and disadvantages of centralization and decentralization.Discuss the pros and cons of tall versus flat structures.Outline the different kinds of structure a firm can operate within and explain how strategy should determine structure.Describe the different integrating mechanisms managers can use to achieve coordination within a firm, and explain the link between strategy, environment, and integrating mechanisms.Organization ArchitectureOrganization architecture: The totality of a firm’s organization, including formal organization structure, control systems, incentive systems, organizational culture, and people.Organization structure: The location of decision-making responsibilities in the firm, the formal division of the organization into subunits, and the establishment of integrating mechanisms to coordinate the activities of subunits.Organization ArchitectureControls: Metrics used to measure the performance of subunits and to judge how well managers are running those subunits.Incentives: Devices used to encourage desired employee behavior.Organizational culture: Values and assumptions that are shared among the employees of an organization.People: The employees of an organization, the strategy used to recruit, compensate, motivate, and retain those individuals, and the type of people they are in terms of their skills, values, and orientation.Organization ArchitecturePeopleControlsIncentivesStructureCultureDesigning StructureVertical differentiation: The location of decision-making responsibilities within a structure.Horizontal differentiation: The formal division of the organization into subunits.Integrating mechanisms: Mechanisms for coordinating subunits.Centralization Versus DecentralizationCentralization: The concentration of decision-making authority at a high level in a management hierarchy.Decentralization: Vesting decision-making authority in lower-level managers or other employees.Arguments for CentralizationCentralization can facilitate coordination.Centralization can help ensure that decisions are consistent with organizational objectives.Centralization can avoid duplication of activities by various subunits within the organization.By concentrating power and authority in one individual or a management team, centralization can give top-level managers the means to bring about needed major organizational changes.Arguments for DecentralizationTop management can become overburdened when decision-making authority is centralized.Motivational research favors decentralization.Decentralization permits greater flexibility—more rapid response to environmental changes.Decentralization can result in better decisions.Decentralization can increase control.Centralization vs. Decentralization in PurchasingCentralize for greater cost control and corporate leverageDecentralize for nimbler procurement responsivenessCentralize procurement of common productsDecentralize procurement of specialized productsAlign purchasing structure with corporate strategy, structure, and sizeSource: Global Best Practices, PricewaterhousecoopersQuestion Decentralization argument works for large businesses. For a small business, it is better to have centralization. Do you agree? Explain.Decentralization and ControlDecentralization ofdecisions to asubunit Increases responsibility Which increases accountabilityThereby enhancingcontrol.The Starfish and the SpiderOri Brafman and Rod Beckstrom show why businesses need to embrace their own decentralized systems in their book called The Starfish and the Spider.The book's central metaphor recognizes that if you cut the leg off of a spider, you have at best a (crippled) spider. But if you cut off the leg of a starfish, the starfish will grow a new leg.Traditional centralized organizations are the spiders, and traditional decentralized organizations are the starfish.

Result: Ranbaxy's managers adopted a global mind-set and began spending a substantial amount of time in their most important market—the United States.Source: The McKinsey Quarterly, 2005 Number 2Formal Integrating MechanismsDirect contact: This is the simplest integrating mechanism. Managers of the various subunits just contact each other whenever they have a concern.Liaison roles: This is a bit more complex than direct contact. As the need for coordination between subunits increase, integration can be improved by assigning a person in each subunit to coordinate with another subunit.Teams: When the need for coordination is greater still, firms use temporary or permanent teams composed of individuals from the subunits that need to achieve coordination.Matrix structure: When the need for integration is very high, firms may institute a matrix structure, in which all roles are viewed as integrating roles.Integrating MechanismsHighLowNeed for coordinationSimpleComplexIntegrating mechanismsCentralizationDirectcontactLiaisonrolesTeamsMatrixstructureFavored by firms inrapidly changing andhigh-technologyenvironmentsFavored by firmsin stable and low-technologyenvironmentsQuestion ABC Information, Inc. operates in a rapidly changing high-technology environment.
