IMPROVING A RAILWAY CONTROL TEST SYSTEM IN PAKISTAN

Abstract

The focus company is an international Rail Control Solution firm.  It has a contract for providing a modern railway signaling system in Pakistan.  Significant delays have prolonged the implementation and increased costs.  One cause is the testing failure of the Controller Cabinet, and this research concentrates on that.

Six-Sigma methodology is used, with its five phases: define, measure, analyze, improve, and control.  The five phases stimulate improvement in the work process, the project’s deliverable performance, and quality assurance, which lead to project efficiency and cost effectiveness.  The failure rate is reduced to the contract tolerance target.  The implementation of these improvements could bring success to the firm’s cabinet start-up test, and thus remove the delays and costs.
