Quantitative Research Design
Systemic Aspect• Structural Aspect
– Man, Machine, Material
• Functional Aspect– Man-man, Man-Material, Man-Machine, Feed-
back
• Boundary• Environment
– Stakeholder and Societal
• Objective– Unitary, pluralist, coercive

Quantitative Research Design
Characteristic of Integrated Approach
• Problem : Real• Model : Valid• Solution : Feasible• Decision : Effective• Action : Implemented
What IE has to do?• Problem Identification• Generate alternatives• Know the standard models• Decide performance criteria• Choose the best solution• Make decision• Anticipate managerial implication• Action
