Overview

This randomized trial evaluates a structured guideline for applying MOSA in ATS, indicating significant cost reduction and improved scalability.

Key Points

  • The study aims to establish structured guidelines for applying the modular open systems approach (MOSA) in automatic test systems (ATS).
  • Developed a structured design guideline operationalizing the five pillars of MOSA.
  • Validated the guideline through a real-world implementation case involving legacy fixed ATS.
  • Analyzed the impact of the proposed guideline on cost efficiency and scalability.
  • Achieved up to 90% reduction in man-month (MM) for ATS operations.
  • Resulted in a total cost reduction of up to 78.3%, including direct material expenses.
  • Supported a wide range of units under test (UUTs) on a single ATS platform.
