Optimization of Staffing Levels and Personnel Budgeting Through Standardized Job Descriptions and Workload Analysis: A Case Study of Operations Director 1's Projects at PT Wijaya Karya (Persero) TBK

This research addresses the critical business issue of optimizing staffing levels and streamlining personnel budgeting within WIKA through the standardization of job descriptions and the determination of optimal personnel numbers. The study, driven by three key research questions, involved analyzing data from 26 medium-scale projects using Lean Office tools and Workload Analysis formats. Standardizing job descriptions led to a significant reduction in redundancies, with the Commercial section decreasing from 81 to 74 roles, Engineering from 37 to 21, and Finance & HC from 34 to 24. Optimal staffing levels were established by validating average working times with expert judgment, resulting in a more efficient allocation of human resources. This optimization saw the Finance & HR team reduce from 6 to 5 employees, Engineering from 9 to 8, and Commercial from 6 to 5, increasing individual work times and ensuring alignment with operational needs. Proper budget standards for personnel costs were developed by comparing historical and current data, leading to significant cost savings: Rp 243.69 million in Finance & HC, Rp 213.91 million in Engineering, and Rp 127.02 million in Commercial. These findings demonstrate that WIKA can enhance its operational performance and efficiency by implementing standardized job descriptions, optimal staffing levels, and accurate budget standards. Recommendations include adopting these standards across all medium project classifications and maintaining regular reviews to ensure continuous improvement, ultimately supporting sustainable growth in the construction industry.
