2. Consider the following project network and activity times (in days): Activity | A | B | C | D | E | F | G Time | 3 | 2 | 5 | 5 | 6 | 2 | 2 Activity | Time (days) Normal | Time (days) Crash | Cost ($) Normal | Cost ($) Crash A | 3 | 2 | 800 | 1400 B | 2 | 1 | 1200 | 1900 C | 5 | 3 | 2000 | 2800 D | 5 | 3 | 1500 | 2300 E | 6 | 4 | 1800 | 2800 F | 2 | 1 | 600 | 1000 G | 2 | 1 | 500 | 1000 a. Find the critical path and the expected project completion time. b. What is the total project cost using the normal times? c. Assume that management desires a 12-day project completion time. What activities should be crashed? d. What is the total project cost for the 12-day completion time?

Step 1
The critical path is the sequence of activities that add up to the longest overall duration. This path must be completed on time for the project to be completed on time. Show more…

Development of a new deluxe version of a particular software product is being considered by Ravi Behara's software house. The activities necessary for the completion of this project are listed in the following table: Activity | Normal Time (weeks) | Crash Time (weeks) | Normal Cost | Crash Cost | Immediate Predecessor(s) --- | --- | --- | --- | --- | --- A | 4 | 3 | $2,000 | $2,600 | — B | 2 | 1 | 2,200 | 2,800 | — C | 3 | 3 | 500 | 500 | — D | 8 | 4 | 2,300 | 2,600 | A E | 6 | 3 | 900 | 1,200 | B F | 3 | 2 | 3,000 | 4,200 | C G | 4 | 2 | 1,400 | 2,000 | D, E (a) What is the project completion date? (b) What is the total cost required for completing this project on normal time? (c) If you wish to reduce the time required to complete this project by 1 week, which activity should be crashed, and how much will this increase the total cost? (d) What is the maximum time that can be crashed? How much would costs increase?

Atkinson Construction assembles residential houses. It uses a job-costing system with two direct-cost categories (direct materials and direct labor) and one indirect-cost pool (assembly support). Direct labor-hours is the allocation base for assembly support costs. In December 2016, Atkinson budgets 2017 assembly-support costs to be $8,800,000 and 2017 direct labor- hours to be 220,000. At the end of 2017 , Atkinson is comparing the costs of several jobs that were started and completed in 2017 . $$\begin{array}{lcc} & \text { Laguna Model } & \text { Mission Model } \\ \hline \text { Construction period } & \text { Feb-June 2017 } & \text { May-0ct 2017 } \\ \text { Direct material costs } & \$ 106,550 & \$ 127,450 \\ \text { Direct labor costs } & \$ 36,250 & \$ 41,130 \\ \text { Direct labor-hours } & 970 & 1,000 \end{array}$$ Direct materials and direct labor are paid for on a contract basis. The costs of each are known when direct materials are used or when direct labor-hours are worked. The 2017 actual assembly-support costs were $\$ 8,400,000,$ and the actual direct labor-hours were 200,000. 1. Compute the (a) budgeted indirect-cost rate and (b) actual indirect-cost rate. Why do they differ? 2. What are the job costs of the Laguna Model and the Mission Model using (a) normal costing and (b) actual costing? 3. Why might Atkinson Construction prefer normal costing over actual costing?
