Read the below mini case carefully and answer the questions: Adi Nor (AD!) is a Network Specialist with Selangor's Water Works Department. ADI enjoyed working with the department and helping with developing the city's infrastructure. He is aspiring to become a certified project manager. ADI was recently invited to attend an important project review meeting for a large development project for Bandar Sunway. This WaterPro Project would use sophisticated technologies such as Artificial Intelligence and Wireless Communications to help many other projects, from laying fibre-optic cables to water lines. However, ADI was very surprised because most of the meetings were spent discussing cost-related issues. The project sponsors were reviewing many existing projects to evaluate their progress to date and the potential impact on their budgets before dicussing the funding for any new projects. ADI did not understand many of the terms and charts the presenters were showing. For example, the Earned Value term that they are presenting, the estimating methods that were used to present the cost of the projects and so on. ADI thought he would learn more about the new technologies the WaterPro Project would use; instead, he discovered that the cost estimates and the project benefits were of most interest to the meeting participants. Answer the following: Based on the gathered information from the above, what lessons can be learned from this mini case description?
