Cycle time is the time taken to complete manufacturing a single unit. Lead time is the time spent from receiving the customer order (start date) to its final delivery (end date). If the cycle time is higher than the lead time, then it means that there is an overproduction of the product and if the cycle time is lesser than the lead time, then it means that there is underproduction of the product. Accurate prediction of cycle times is critical to mine planners as it impacts on production targets and hence, the budgets. Decline in performance time is caused by factors such as daily safety meetings, lunch breaks, blasting, tools break down and the daily machine service.
