Overview of the Experiments (5)
- Illumination Experiment
- Bank Wiring Experiments
- Phase 1: Relais Assembly Test
- Phase 2: Relais Assembly Test
- Phase 3: Mica-Splitting Test
Illumination Experiments (purpose, result and interpretation)
Purpose: Effect of light intensity on workers' productivity
Result: Increased productivity of all groups
Interpretation: Effect of socio-psychological factors on workers' productivity
Phase 1: Relais Assembly Experiments (purpose, variation measured, results and interpretation)
Problematic Setup
Puropse: Effect of distribution/lenght of breaks and working hours on productivity (controlling for socio-psychological influences)
Variation measured:
- Breaks and working hours (intended)
- Change of payment plans (unintended)
- Confidence building measures (unintended)
- Change of working place to laboratory (unintended)
Result: 30% increase in output (after 2 years)
Interpretation: Increasing efficiency is primarliy explained by socio-psychological factors (but simultaneous variation of several variables)
Phase 2: Relais Assembly Experiments (purpose, variation measured, result, consequence)
Effects of Wages
Purpose: Clarifying the results of phase 1 and testing solely for the effects of payment
Variations measured: Change of payment plans
Result: Immediate increase in output of 13%
Consequence: experiment had to be terminated since the difference in payment plans between the members of the test group and "normal" workers provoked agitation.
Phase 3: Mica-Splitting Experiments (purpose, variations measured, results, interpretations)
Mica-Splitting Experiment
Purpose: Clarifying the result from phase 1
Variations measured:
- Breaks and working hours (intended)
- Change of working place (intended)
- Confidence building measures (intended)
Result: 15% increase in output (15 months)
Interpretation: max. 15% of the increase in output is caused by monetary incentives; remaining 15% of the increase has mostly socio-psychological reasons. (But task and payment plan are different from phase 1)
Summary of the Experimental Results in Three Phases
Phase 1: 30% because of all the factors (Breaks & working hours, socio-psychological factors and payment plans)
Phase 2: 13% because of the payment plans
Phase 3: 15% because of the breaks & working hours and socio-psychological factors
Bank Wiring Experiments: Group Behavior (purpose, results, consequence)
Purpose: Influence of group behavior on productivity
Result:
- Emergence of norms of appropriate daily output
- Manipulative stabilization of level of daily output
- Creation of capacity reserves
- Influence of personal relations on quality tests
Consequence: Discovery of "the informal organization"
Effect form "Informal Organizations"
Informal aspects are no longer considered solely as causing problems in the organization
Key Findings of the Hawthorne Studies (3)
Existence of a "human" organization besides the technical one:
- The organizational reality comprises more than the formal and technical structure
- Readiness to work is dependent on the "informal organizaiton" (social conventions, rules, traditions, personal relationships)
- Possibility to increase output through attention to employee's social needs
4.3 Discussion and Critique on the Hawthorne Experimens
-
Accusation of (unintentional) Data Manipulation during the Experiments (2)
- Systematic mitigation of the effects of factors other than social-psychological ones (e.g. wage increase, breaks)
- "Employee-oriented leadership" is in fact not all the time as employee-oriented as declared
Secondary Data Analysis with Different Results (purpose, results, interpretation)
Purpose: Secondary data analysis on the Relais Assembly Experiments/ Phase 1
Results: Three variables explain most of the observed effects:
- Disciplinary reassured of the management
- Impact of the economic depression
- Recreation breaks
Interpretation: Socio-psychological factors and variations in wages have little effect
Ideological Bias of the Experiments
Academic objectives get mixed with the propagation of social reform
4.4 Effects and Critical Appraisal
-
Effects and Consequences form the Experiments (3)
- Integration of socio-psychological factors into organization research
- Discovery of the "informal organization"
- Switch from the concept of "economic man" to the concept of "social man"
Modul 5: Contingency Theory
-
5.1 Historical Context and Theoretical Origins
-
Historical Context (1960s/70s)
- Trend for empirical methods
- Higher employee qualification
- More complex organizations
- Progess of IT-systems and static software
→ Empirical analysis of organizational structures
Starting point of the Contingency Theory
Starting point is the attempt to test Max Weber's description of bureaucracy
- Experiments not applicable in context of larger structures
- Transformation to "exact and objective science
5.2 Research Interests and Assumptions
-
Research Interests: Main Questions (3)
- How can you describe and operationalize organizational structures to account for differences between organizations in empirical analysis?
- Which organizational and environmental contingencies can explain differences between organization structures?
- What effect do specific structures and environments have on the behavior of the organizational members and efficiency? Is there one particularly efficient structure for every contingency?
Hypotheses about the effects (3)
- of the situation (i.e. contingencies) on the organizational structure
- of the organizational structure on behaviour
- ot the behaviour efficiency
→ derived empirically rather than theoretically
Dimensions of internal situation (5)
- product range
- size
- production and IT technology
- legal form and ownership
- age
Dimensions of external (environmental) situation (5)
- competition
- customers
- technical progress
- society
- culture
Dimensions of Structure (6)
- Specialization (division of labour)
- Standardization (procedure directives)
- Formalization (*the files")
- Centralization (locus of authority to make decisions)
- Configuration ("shape" of the role structure)
- Coordination
Concepts of Behaviour and Efficiency
Organizational Structure → Behaviour of Members (?) → Degree of Organizational Efficiency
Operationalization of the structure's influence on behaviour and on efficiency is problematic!
5.4 Empirical Studies
-
Effects of Organization's Size: increase in size (4)
- higher degree of specialization: more positions
- higher degree of coordination: greater hetrogeneity of positions
- higher degree of formalization
- lower degree of centralization
Relation between size and specialization
positive correlation between size (more employees) and specialization
Effect of Production Technology: 3 different types of production
- Degree of Specialization
- Degree of Coordination
- Coordination Mechanism
Shop Fabrication:
- Low
- High
- Personal instruction, self-determination
Assembly Line
- High
- Production: low; Divisions: high
- Program, plan
Automation
- low
- Production: low
- Personal instruction, planning, mutual adjustment
→ Production technology influences structure!
Effects of Environment (2)
Degree of heterogeneity of sub-environments + → Degree of differentiation of subsystems
Degree of integration of subsystems required by the environment + → Degree of integration between subsystems
5.5 Critical Appraisal
-
Importance of the Theory and Practical Implications (4)
- Draws attention to organizational context
- Empirically testable
- Explicit attempt to generate insights for management practice
- Practical impact on organizational design → it changed against the backdrop of Contingency Theory
Critique of Contingency Theory (4)
- Important environmental and structural attributes are being neglected
- Weak explanation for adjustment of the structure of the contingencies (lack of theory)
- Neglecting the role of power and other human factors in organizations
- Conservative recommendations for organizational design
Modul 6: Resource Dependence Theory
-
6.1 Historical Context
-
Historical Context 1970s
- Increasingly dynamic environments
- Increasing concentration of economic power
- Increasing interorganizational activities
→ Empirical analysis of organization-environment relations
