Critical Path formulas 
Forward Pass: (Add 1 day to Early Start)                EF = (ES + Duration - 1)
Backward Pass: (Minus 1 day to Late Finish)
LS = (LF - Duration + 1)
ES = Early Start; EF = Early Finish;
LS = Late Start; LF = Late Finish

EVA = Net Operating Profit After Tax - Cost of Capital (Revenue - Op. Exp - Taxes) - (Investment Capital X % Cost of Capital) EVA - Economic Value Add Benefit Measurement - Bigger is better

Source Selection = (Weightage X Price) + (Weightage X Quality)
