Q. Is that all there is to project management?
A. That is by no way all. There are several aspects to good project management that require attention. In summary these perhaps identified as the management of quality, scope, time cost, contract/procurement risk, human resources, and communications.
All of these eight functional areas as they are called will require careful integration. Additionally a successful project isn't only one which meets its objectives on paper but is as well seen to be successful. In other prose it satisfies the customers. The eight functions mutually with the considerations of integration and stakeholder satisfaction are the ten attributes of effective project management.
