Abstract

The Applied Technology Department at PT. Indospring Tbk encounters significant challenges in managing automation projects, such as uneven workload distribution and the absence of standardized tools for project planning and workload analysis. These issues lead to engineer overload, project delays, and reduced productivity. This study aims to tackle these problems by integrating the Critical Chain Project Management (CCPM) method with the Modified Full Time Equivalent (M-FTE) approach. CCPM is used to identify the critical chain and allocate buffers based on allowance values, while M-FTE calculates manpower needs using adjusted standard times. Researchers collected data through observation and processed this data using this integrated approach to develop and simulate three project management alternatives. The simulation results indicate that Alternative 1 (Option 1) and Alternative 1 (Option 2) are the most effective. Option 1, with five engineers, results in a total FTE of 2080 hours (6.6% above the ideal), whereas Option 2, with six engineers, achieves 1733.3 hours (11% below the ideal). These findings provide a practical framework for managerial decision-making that balances labor efficiency, workload distribution, and project timelines.
