Chapter 6 Review Questions

1. How does the WBS differ from the project network?
The WBS differs from the project network in several ways. The WBS is hierarchical while the project network is sequential. The work packages of the WBS are identified independently of other work packages, have definite start and finish points, require specific resources, include technical specifications and have cost estimates. Networks provide the project schedule by identifying dependencies, sequencing, and timing of activities.

2. How are WBS and project networks linked? Project networks are developed from the WBS. Work packages from the WBS are used to build the activities found in the project network. The network uses the time estimates from the WBS to generate dates for the project. Integration of the WBS and project network is crucial to effective project management. 3. Why bother creating a WBS? Why not go straight to a project network and forget the WBS? Project networks depend on the WBS because work packages from the WBS are used to develop the project network. A network activity can include one or more work packages but all activity time estimates are derived from the task times in the work package. Unlike the project network, the WBS defines all the elements of the project in a hierarchical framework and establishes their relationships to project deliverables.

4. Why is slack important to the project manager?
Slack is important to the project manager because it tells him or her which activities can be delayed and for how long without delaying the project. There are two types of slack: I. Total slack is the difference between the Late Start and Early Start and equates to the amount of time an activity can be delayed without delaying the entire project. II.

Inf 336 - Chapter 6 - Review Questions

...Chapter 6 Review Questions Andrea Ley Berenz INF 336 Prof. Lori Deere August 2, 2013 Chapter 6 Review Questions * Describe the differences between needs identification and defining commercial equivalents and discuss why it is preferable to separate into two stages. The first two steps of the acquisition process are essential to meeting the needs of the company properly. Needs identification is where a purchase begins and when the what, the how much and the when something is needed is determined. When this is done, figuring out the options available to fulfill that need and making sure that it is described in a way that potential suppliers will understand, or defining the commercial equivalent, takes place. I believe that the textbook describes it best: “Many options exist for fastening two pieces of wood together. Using a nail is only one option. Grooving the two pieces of wood using a staple, bolt or screw, or glue are others. Specifying the need first and then identifying the variety of options to meet the need leave the door open to lower cost and better, more innovative, solutions.” (Johnson, Lendeers & Flynn, 2011) These two steps are best tackled separately as making sure that the need is correctly explained will ensure the correct solution is found and that the option chosen is the right fit for the company. * Interpret the value to the organization when early supplier involvement (ESI) is implemented effectively. “Early supply......

...BL-162-01 March 2, 2015 Chapter 30 Review Questions 1. In this case, Alice worked as an agent of Peter. She was authorized to collect accounts. Peter wrongfully discharged Alice before the agreed upon termination of the agency. Peter failed to notify his customers of Alice’s termination. Alice continued to work as an agent and took collections from one of Peter’s clients, Tom. She also collected from a new prospect, Laura. She secured an order, collected payment, sent the order to Peter, and disappeared with the collections. Peter delivered the goods that Laura ordered. In the accounts of Tom, Peter would be unable to sue due to the fact that Alice had actual authority, which is power conferred upon by actual consent given by the principal, although Peter had terminated his agency with Alice he failed to make this known to others. Therefore Tom cannot be penalized because he was unaware of the change in agency and was still in belief that Alice was a working agent of Peter. As for Laura, she was a new prospect. Laura had reason to believe that Alice was an agent of Peter’s. Peter had delivered the goods that Laura ordered through Alice. This gives Laura the impression that Alice was a working agent because she received the order. Based off this fact pattern, Peter would be unable to receive compensation if he sues either Laura or Tom, he failed to notify them that Alice was no longer an agent of his, and he also delivered goods that were ordered through Alice......

...Chapter 3 ANSWERS TO QUESTIONS Q3­1 A primary objective of financial reporting is to provide information that is useful to present and potential investors and creditors and other users in making rational investment, credit, and similar decisions. An accounting system is the means by which a company records and stores the financial and managerial information from its transactions so that it can retrieve and report the information in an accounting statement. A double­entry system standardizes the method that a company uses to record changes in its accounts resulting from various transactions or events. For each transaction or event that a company records, the dollar amount of the debits entered in all the related accounts must be equal to the total dollar amount of the credits. These debit or credit entries affect two or more accounts in the assets, liabilities, and stockholders' equity (including the temporary accounts). All normal accounts on the left side of the accounting equation (assets) are increased by debits and decreased by credits whereas accounts on the right side of the equation (liabilities and stockholders' equity) are increased by credits and decreased by debits. A permanent account is an account whose balance at the end of the accounting period is carried forward into the next accounting period. Examples: Cash, Accounts Payable, Capital Stock. A temporary account is an account that is used temporarily to determine the change in retained earnings that occurred......
