Part of the book series: Understanding Complex Systems ((UCS))

Abstract

Trainings imparted to the company employees are prerequisite for organizational transformation. Impact of the trainings appears in the form of changed behavior and attitude of the employees that contribute significantly for enhancement of the supply chain score of the focal firm. This chapter discusses the types of trainings generally categorized in soft skills and hard skills. Training need analysis is the best proven method utilized to identify the competency gaps of current employees. Soft skills trainings and hard skills trainings are designed for capacity building in order to reduce the gap and raise the employee productivity toward the sustainable supply chain management. Soft skills trainings not only change the attitude and behavior of the employee but as well enhance the motivational level of the employees that ultimately contribute in terms of better product quality and waste reduction. Hard skills trainings improve the technical capabilities of the workers. Reduced waste percentage, improved process settings, declining cost of quality, mistake proofing in product design, and enhanced productivity are the contributing factors for sustained supply chain performance.

Training need analysis is the most appropriate method in the case company for assessing the competency gap. Training budget is allocated accordingly to reduce the competency gap. The objective of this chapter is to design the plausible policies for enhanced supply chain performance conducting experimentation with the simulated system dynamics model. What type of the training is required more and how significantly these training impact the supply chain score for enhanced supply chain performance are the research questions being explored. Experimentation with the model unveils the underlying symptoms and keeps on playing with the model to make the system better behaved. Training which is usually considered as an expenditure can be a valuable asset if its effectiveness improves the supply chain performance.

System dynamics simulated model is developed to design the policy streams for improved supply chain performance.
