ABC is very simple project: it consists of two tasks A and B, where "A = all mechanical" and "B all electronics" of 20 days each. The cost of the mechanical work is $100/day and the cost of electronics is $150/day. Task B can actually start half the way of task A (i.e. the 10th day), so the project can be completed in 30 days. Today is the end of the 15th day of the project and, * the team is exactly on schedule following the 50-50 rules * but the actual cost so far is $2,500 A. What is the Cost Variance? B. What is the expected cost at completion? C. What is the EV? Explain. Attach any spreadsheets or Gantt charts
