George, as the project manager, should take the following steps:
- Assess the reasons behind the variance in the System Testing activity. It could be due to unforeseen issues, dependencies, or problems with the vendor's employees.
- Communicate with the vendor and express the concern regarding the delay and the extra charges incurred. Discuss possible solutions, such as assigning additional resources or escalating the matter to higher management.
