Overview
The document discusses the application of Critical Chain Project Management (CCPM) to improve stoping productivity at Impala Platinum.
Case Study Background
Impala Platinum’s stoping productivity averaged 17m/month, but performance was plateauing and deteriorating. The Accelerated Productivity Improvement (API) program aimed to enhance overall productivity, translating to over R1 billion increase in annual sales. A study identified input, output, and capacity constraints affecting stoping performance, focusing on capacity constraints for day shift drilling.
CCPM Application Methodology
The project team conducted time motion studies to gather data on stoping crews’ performance. Observations revealed a lack of integration among crew activities, leading to inefficiencies. CCPM was applied to enhance teamwork, protect against uncertainties, and improve crew synchronization.
