In the assembly industry, almost all components are outsourced or transferred to other

parties, in order to meet the need for supply. This is referred as outsourcing of production.

The outsourcing of assembly product components is based on a relationship model

between the contractor and the industry. However, there is no relationship or communication

pattern between the contractor or supplier and the assembler. Hence, in order to

accelerate line production and overcome problems with assembly components, the communication

path is shortened by providing a direct communication channel between the

assembler and the supplier or contractor, in order to communicate any problems that arise

during the assembly process by internal communication within the industry. The purpose

of this study is the design and development of a web-based software application electronic

data interchange (EDI) that can be used as a tool for communication between the assembler

and supplier. The EDI application provides formal communication between the assembly

industry and the contractor providing the components or parts needed in the assembly process.

The main purpose of using EDI technology is to help the assembler to communicate

the relevant documents to suppliers quickly, accurately and efficiently. The documents to

be communicated are in the form of reports or claims, and are related to non-conformities,

errors and component difficulties arising during the assembly process. This research novelty

is providing direct communication between assembly and supplier by using EDI application

that can give contribution in manufacturing area so it can accelerate the line production in

assembly.
