Alternative Organizational Structures v What are alternative ways to design an organizational structure? v What are the advantages and disadvantages of various design alternatives ? v How do we make these choices in light of organizational context? –External environment –Organizational life-cycle –Organizational technology

Functional Structures Strengths: Economies of scale in-depth skill development Stable Environment Routine Technology Weaknesses: Slow in responding environment Hierarchy overload Poor horizontal coordination Emphasis on functional goals Less emphasis on innovation

Divisional Structures v Product Structure (Self contained product groups structure) v Geographic Structure v Market Structure Structures that are uni-focussed in that the divisions are organized according to product groups, services, geography,programs, or markets.

Self contained product groups structure Strengths: increases coordination across functions allows adaptations decentralizes decision making accommodates large size Weaknesses: reduces coordination across product lines reduces economies of scale reduces specialization reduces standardization

Generic Hybrid Structures Product Division Advantages More adaptive at division level without sacrificing efficiency in centralized functions Better alignment between functional and divisional goals Disadvantages Higher administrative overhead Misalignment between vertical & horizontal coordination Multi-Divisional Advantages More sophisticated control & integration systems Better capital resource allocation decisions corporate level can focus on long-term strategies Disadvantages Measurement of divisional performance New layers in management Product Team Advantages Higher decentralization Higher integration at team level responsive to market demands and shorter development time Disadvantages Limited coordination across teams Loss of corporate control

Matrix Structure Strengths Reduces functional barriers Increases communication Flexible use of human resources Product & functional focus Weaknesses Lacks stable control structure Ambiguity of dual authority Time consuming May increase costs

A Critical Contextual Factor: THE EXTERNAL ENVIRONMENT v Why is it important? Need for INFORMATION Need for RESOURCES v How is it conceptualized? The Critical Dimensions of Environment Complexity (Homogeneous ---- Heterogeneous) Dynamism (Stable ---- Unstable) Munificence (Resource Rich ---- Resource Poor) Organization of the environment (Market Structure)

Pharmaceutical Industry v Supply chain management v Reduction of inventories v Strategic sourcing v Advertising directly to consumers v Differentiated advertising Years between the launch of a drug and its first competitor Internal Strategies

Strategies for managing environmental Uncertainty v Add new positions and departments as the task (Specific) environment becomes more complex. v Establish buffer mechanisms to protect the technical core of the organization from environmental changes. v Create new boundary roles that monitor the environmental demands.

Strategies for Managing Symbiotic Interdependencies Symbiotic interdependencies arise when the output of one organization is input for another. v Interorganizational Strategies: Developing a good reputation Co-optation Strategic alliances – Long-term contracts – Networks – Minority ownership – Joint-ventures Mergers, takeovers, and vertical integration

Strategies for Managing Competitive Interdependencies Competitive interdependencies arise when organizations compete for similar scarce inputs or outputs. v Interorganizational Strategies Collusion and cartels Trade associations Political activity (Regulations and lobbying) Strategic alliances Mergers and takeovers
