Practice Problem

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 $3.$

$\backslash$table$[[$Module$,$Month $1,$Month $2,$Month $3,$Month $4,\backslash$table$[[$Status at$],[$end of$],[$Month $3]]],[\backslash$table$[[$Pedestrian$],[$Detection$]],$S$---$F$,,,,\backslash$table$[[$Complete$,],[$spent$],[1000$ S$]]],[\backslash$table$[[$Road$-$sign$],[$detection$]],,$S$----$PF$,---F,\backslash$table$[[$Complete$,],[$spent$],[1200$ S$]],],[\backslash$table$[[$Traffic lane$],[$identification$]],,,$PS$--$S$--$PF$,\backslash$table$[[50\%$ done,$],[$spent $600$ $$]],],[\backslash$table$[[$Vehicle$],[$proximity$],[$detection$]],,,,$PS$---$PF$,\backslash$table$[[$Not yet$],[$started$]]]]$

Key $S=$ Actual Start, $F=$ Actual Finish, $PS=$ Planned Start, and $PF=$ Planned Finish

Use the above project status chart and calculate the measures given in the table below.
