About this Presentation
The presentation title is Theory of Constraints - A success in open pit mining. For years the mining industry has been struggling due to higher operational cost and lower commodity prices. This has really resulted in closure of many mines and many jobs were lost. In a continent like Africa this has played out to be a serious problem knowing their circumstances. Every job kept in Africa feeds 10 more people. Mining has been the back bone of many African countries' economic growth. TOC has proved to be one of the best solutions that should be implemented by mining companies to improve productivity and essentially increase profits in Africa. The research objective here is to analyse and trace the dramatic improvements and where theory of constraints was successfully implemented in south African mines. The following specific objectives will assist in comprehending this research model all the more: To assess knowledge levels on TOC of mining companies which executed theory of constraints; To assess the effect of the TOC when applied in mining companies; To analyse the dramatic change after the implementation of the TOC; To analyse the whole process i.e. before, during and after the implementation of TOC.

To help you get the most value from this session, we’ve highlighted a few key points. These takeaways capture the main ideas and practical insights from the presentation, making it easier for you to review, reflect, and apply what you’ve learned.
The company identified tires as a system constraint due to long lead times for tire supply and increased demand for tires.
The company introduced a tire repair shop to prolong the life of tires and reduce costs. This led to significant cost savings and improved productivity.
The company trained its employees on the importance of tire management and how to properly handle tires, which further contributed to the improved productivity and cost savings.
