project.Can the project be completed within the

budget?

TOTAL COST 18 100

Total project cost

= $ 50 000 + $ 18 100

= $ 68 100

The project cost is within $ 70 000, thus it can be completed within the budget.

Will the project require more than $3600 in any week? If problems exist, how might Roberts overcome them?

Assumptions*Activities B,C and D must be paid for when the item is received*The costs of all activities that spam more than one week can be prorated*Each week contains five work days

F:\gantt chart mustang.doc

The activities cost from day 7 to day 12 = $( 850 + 640 + 250 + 350 + 650) = $ 2 740

<$3,600However,

The activities cost from day 3 to day 7

= $( 1170 + 1470 + 1400 + 850 )= $ 6 290

>$3,600

GANTT CHART

How to overcome the problem?Robert can start some activities later since some activities have slack time;

such as slack for activity k = 14 days

CONCLUSION

CPM/ PERT are very handy when it comes to

project planning because :

Assist managers to plan and manage resources effectively

Monitor schedules and cost

RASAS will be able to complete the project before the display in Detroit within the required timeline and budget
