Flashcards
Planning Department
Planning foremen: route clerk, instruction card clerk, time and cost clerk
Production Department
Production foremen: gang boss, speed boss, repair boss, inspector, shop disciplinarian
Procedure of Tme and Motion Studies (5 steps)
- Division of tasks into elementary tasks
- Identification and elimination of unnecessary activities
- Identification of the mannes in which the most skilled workers perform the elementary tasks and timing of the fastest and most efficient mannor (stop watch)
- Documentation of the elementary tasks and the respective time necessary
- Extra time for
- Disruptions
- Learning
- Recreation
Task and Bonus
in the past
wage according to time or pieces accomplished
Task and Bonus
New
- definition of a specified work task
- payment of a fixed bonus if task is accomplished and reduction of bonus if not
Selection and Training of Workers (4)
- Tests as part of the recruitment process
- Self-selection of workers with regard to task-and-bonus system
- Work allocation according to abilities and skills
- Systematic development and training of workers
→ Creation of "first-class" work force
Conciliation of Worker and Manager
- Increase in productivity through "Scientific Management" meets the interests both of managers and workers, if surplus is shared
- "Scientific Managers" take control over production process
→ Transformation of the "management-labor conflict" into "management-labor cooperation"
3.4 Fordism
-
Henry Ford (1863 - 1947)
Optimization of assembly-line technology (inspired by Taylor's theory)
Ford's Vision:
"I will build a car for the great multitude. It will be constructed of the best materials, by the best men to be hired, agter the simplest designs that modern engineering can devise. But it will be low in price that no man making a good salary will be unable to own one."
Principles of Ford (2)
- Work comes to Workers
- Standardisation
Work comes to Workers (3)
- Optimization of the layout of work stations in order to minimize distance between them
- Use of slideways, so workers do not have to move
- Use of slideways to determine working pace
Standardisation (2)
- Reduction of the range of products (one model, one colour)
- Increasing precision in the manufacturing of component part
Effects on Production at the Ford Motor Company (4)
- Reduction of the average work step
- Reduction of production time per car
- Reduction of working hours to 8 h, simultaneous doubling of wages
- Price reduction per car
Real causes of increased productivity disputed!
Increases in productivity partly observed already before the implementation of the assembly line.
3.5 Effects and Critical Appraisal
-
Impact of Taylorism on Practice
Initially (5)
- Merely small number of larger companies with mass production at that time
- Resistance against "inflation" of the middle management
- Resistance of industrialists (and existing middle management) against loss of power on behalf of the new "scientific manager"
- Introduction of Taylorist principles considered too costly and time consuming
- Opposition from unions and industrial disputes
Impact of Taylorism on Practice
Later (3)
- Propagation of Taylorism by Lenin as appropriate form of management for the socialist state
- Increasing popularity of Taylorism through Fordism
- Still today many management concepts based on Taylorist approach (CIM, Reengineering)
Taylor's Ideas in Contemporary Management Practice (7)
- Management-labor coorperation
- Time and motion study
- Standardization
- Task
- Bonus
- Management training
- Scientific selection
Management-labor cooperation
Accepted: partly
Manifested in (outgrowth): Greater management-labor cooperation (but conflict not eliminated)
Time and motion study
Accepted: yes
Manifested in (outgrowth): Widespread use; standard times
Standardization
Accepted: yes
Manifested in (outgrowth): Standardization proccedures in many spheres; human engineering
Task
Accepted: yes
Manifested in (outgrowth): Goal setting, MBO, feedback
Bonus
Accepted: increasingly
Manifested in (outgrowth): proliferation of reward system, Scanion Plan
Management training
Accepted: yes
Manifested in (outgrowth): Management responsibility fo employee training
Scientific selection
Accepted: yes
Manifested in (outgrowth): development of industrial psychology and personnel management
Scientific Critique (4)
- "Science without theory"
- Lack of scientific rigour in experiments
- Simplistic concept of human being
- contradictory assumptions about the human nature of workers as compared to engineers
Practical Critique (4)
- Exhaustion of workers due to a lack of consideration of health issues
- Specialization and separation of manual and intellectual tasks are contrary to human needs
- Application limited to mass production
- Systematic de-qualification of workers
→ Counter movement "Human Relations"
→ Further developments (e.g.Tayloristic models of team work)
Modul 4: Human Relation Movement
-
4.1 Historical Context
-
Historical Context (4 factors)
- Development of the labor movement
- High labor fluctuation
- Application of socio-psychological practices and insights to improve work processes
- Integration of different social aspects into management philosophies
→ labor shortage
4.2 The Hawthorne Experiment
-
Initiators of the Experiment (3)
- Fritz J. Roethlisberger
- William J. Dickson
- Elton Mayo (later involvement in the experiments)
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
