So, we solve this issue by finding out the late time analysis. We drill down on every single process and understand what causes the delay.
If we have delayed something by five days today, how will it affect my delivery date after six months?
We try to analyze and keep checkpoints everywhere to understand where this process would get out of hand. So that's what we are doing in late-time analysis. Over time, if the product is made again and again, we would also analyze the bottlenecks in the processes and find out the exact cause.
Understanding what products we are making, the problems, then arriving on the reason for the lag and rectifying it is what we do for manufacturing sectors.
