A variety of factors increases the risk of making errors when you use isolated cost management systems. I was recently interested in this and found a guide where I learned more about cost control in construction and that it is part of project management. Many errors can be made, such as duplication of effort and data transfer into and out of accounting systems. Team members may not be able to view the data in real time. This can lead to fragmented cost management processes that can result in wasted time and money.
