Review the FOUR (4) steps of Project Monitoring and Control (12 marks) (b) Assume that you are a project manager tasked to build a square garden of four sides around a piece of land, as in the figure below. You are given a budget of $500 to build each side, and you have a schedule of completing one side of the hedge each day. Hence, you are expected to finish the project in four days at a cost of $2,000. However, as with many projects, there are some unforeseen circumstances, resulting in the following: Day 1: ONE wall completed within budget Day 2: Work was completed and there was an additional spending of $50 beyond budget Day 3: Work was completed but only with a total spending of $250 At day 3, you decided to evaluate the progress of the project. Apply project management techniques to calculate / determine the following: (i) What is the planned Value? (3 marks) What is the Earned Value? (3 marks) (iii) What is the Actual Cost? (3 marks) (iv) What is the Cost Variance? Based on this, is the project over or under budget? (3 marks) (v) What is the Schedule Variance? Based on this, is the project ahead or behind schedule? (3 marks) (vi) What is the Cost Performance Index or CPI? How many cents are you getting from every dollar spent
