Expected Value Method

You have a project to build an Automated Driving Assist System (ADAS). The ADAS has four modules; Pedestrian Detection, road-sign detection, traffic lane identification and Vehicle proximity detection. Each module is to take one month to build and 1000 has been budged per module. The modules are planned to be completed one after the other. Today is the end of month 3.

Module	Month 1	Month 2	Month 1	Month 4	Status at the end of month 3
Pedestrian Detection	S-----F				Complete, spent 1000$
Road-Sign Detection		S----PF	-----F		Complete, Spent 1200$
Traffic Lane Identification			Ps----S----PF		50% done, spent 600$
Vehicle Proximity detection				PS-----PF	not yet started

Key: S= Actual Start. F=Actual Finish, PS= Planned start, PF= Planned finish
