  6. 6. 316   Chapter 6Exam QuestionsAnswers1. Answer: CYou’ll definitely get some questions that ask you about crashing and fast-tracking, and it’s important to knowthe difference between them. When you crash the project, it means that you add resources to it, especiallyto the critical path. There’s no real risk in doing that—in the worst-case scenario, the extra people just sitaround!—but it does cost more. Fast-tracking means adjusting the schedule so that activities overlap. Thesame resources are doing the work, so it’s not going to cost more, but it’s definitely riskier, because nowyou’ve eliminated buffers and possibly broken some dependencies! And remember that crashing or fast-tracking won’t always work to make the project go faster!2. Answer: DCalculating the early start (ES) of an activity isn’t hard. All you need to do is look at the early finish (EF) of theprevious activity and add one. If there’s more than one predecessor, then you take the largest EF and add one.In this case, the predecessors to activity F are D, with an EF of 9, and E, with an EF of 12. So the ES of F is12 + 1 = 13.3. Answer: AIt’s just as easy to calculate the late finish (LF). Look at the following activity, take its LS (late start), andsubtract one. If there’s more than one following activity, use the one with the lowest LS. So for activity F in thequestion, the following activities are G, with an LS of 17, and H, with an LS of 11. So the LF of F is 11 - 1 = 10.4. Answer: CDon’t let the jargon fool you! You don’t need to know anything about software testing to answer this question.When you have two activities, and the first activity has to be timed so that it finishes before the second onestarts, then you’ve got a Finish-to-Start relationship, or FS.5. Answer: BThis is a Which-is-next question that describes a project that’s completed the Define Activities, SequenceActivities, Estimate Activity Resources, and Estimate Activity Durations processes. The next process in TimeManagement is Develop Schedule, which means that the next thing you do is create the schedule!Did answer A trick you? No need forrolling wave planning when you’ve gotenough info to define all the activities!exam answersDownload at Boykma.Com
  7. 7. you are here 4   317time managementExam QuestionsAnswers6. Answer: DThe schedule baseline is an output of the Develop Schedule process, not an input. You should definitelyknow what goes into the schedule baseline: it’s a specific version of the schedule that you set aside anduse for comparison later on, when you want to know if the project is running late.7. Answer: AYou always want to be honest with your estimates. Every project has unknowns and risks, and there’s noway to estimate any activity exactly! Luckily, we have tools to deal with this. You can use reserve analysis,a tool of Estimate Activity Durations, to come up with a contingency reserve that you can use to plan forthese risks.8. Answer: BCritical chain method is a technique that’s part of Develop Schedule that lets you figure out how to handlethe problems that come with having limited resources. You use it to shuffle both activities and resourceson your critical path. One important aspect of the critical chain method is that you can use it to add buffersto the schedule to reduce the risk of certain activities.9. Answer: AWhen you draw out a network diagram for the activities in the table, you end up with four paths. And youdefinitely should draw out the activity diagram for a question like this! You’re allowed to use scratch paperon the exam, and this is one place where you should definitely do it. Of the four paths, only one has thelongest duration: Start‑A‑B‑C‑Finish, which has a duration of 6+ 4 + 8 = 18. That’s the critical path.I get it—we can use theschedule baseline the same way that weuse the scope baseline! We take a snapshotof it and then save it, so we can compare theproject’s performance against it later!Download at Boykma.Com
  8. 8. 318   Chapter 610. Answer: CActivity F is in the path Start-A-D-E-F-Finish. This path has a duration of 6 + 1 + 1 + 2 = 10. The float ofan activity is the longest time it can slip before it affects the critical path. In this case, activity F can slip by8 without causing the path that it’s on to go beyond the critical path. But any more than that, and its pathbecomes the new critical path!11. Answer: CThis is the definition of fast-tracking, and you’re probably getting the hang of this one by now. You may geta question like this, but you’ll almost certainly see fast-tracking as an incorrect answer to several questions!12. Answer: ARemember that when you see “slack,” it’s the same thing as float. Either term could appear on the exam!13. Answer: BThis question is asking about the Estimate Activity Durations process. Take a look at the answers—there’sonly one answer that’s used in that process: you need to start with the activity list in order to do theestimates for the activities! The other answers are things that are inputs, tools, or techniques for otherprocesses.14. Answer: CIt’s not hard to remember the order in which the Time Management processes are performed. If you usea little common sense, you can reason your way through a question like this. You need to define youractivities before you can sequence them, you need to know who’s going to be doing an activity before youcan estimate how long it’s going to take, and you need to do all of that before you can build a schedule!15. Answer: AYou’ll have to know the different kinds of estimating techniques for the exam. You don’t necessarily haveto be good at doing them, but you should recognize which are which. Parametric estimating is when youplug values into a formula, program, or spreadsheet and get an estimate. Analogous estimating usessimilar activities from past projects to calculate new estimates. Three-point estimating uses an optimistic,pessimistic, and realistic estimate.Exam QuestionsAnswersDid you notice answer A? Don’t forgetthat the float of any activity in thecritical path is zero!When a question asks what you’d use for a process,it’s asking you to pick an input, tool, or techniquethat’s part of the process.exam answersControl Schedule isn’t included in the list of procesesbecause if a schedule change happens, you’ll have togo back and revisit the other Time Managementprocesses. So it doesn’t have a specific order!Download at Boykma.Com
  9. 9. you are here 4   319time managementExam QuestionsAnswers16. Answer: CThis question is asking you to apply the PERT three-point estimation formula: (Optimistic Time + 4 x Most LikelyTime + Pessimistic Time) ÷ 6. When a question gives you these values directly, it’s easy. But in this case, toanswer the question you had to figure out the values for the Optimistic Time and Pessimistic Time, which meantthat you needed to look at the assumptions that the team was making. The most likely time was given: 27 weeks.The best case scenario would come in two weeks earlier, at 25 weeks, and the worst case would come in fiveweeks late, at 32 weeks. So the estimate is (25 weeks + 4 x (27 weeks) + 32 weeks) ÷ 6 = 27.5 weeks.17. Answer: CThe path Start-E-D-C-End has a duration of 8 + 2 + 4 = 14, which is the longest total duration in the entire network.18. Answer: BActivity A is on three different paths: Start-A-B-C-End (13), Start-A-D-C-End (12), and Start-A-D-G-End (9). Tocalculate its float, you take the longest path’s length and subtract it from the lenth of the critical path: 14 - 13 = 1.19. Answer: ASince activity E is on the critical path, its float is zero, because the float of any activity on the critical path is zero.20. Answer: AThe schedule management plan tells you how changes to the schedule are to be handled. Any time there’s achange, the first thing you should do is consult the plan to see how it should be handled.It looks like there will be abunch of questions on thecritical path method! It’s agood thing I’ve got so muchpractice with it.Sometimes you’ll get a question aboutapplying a formula, but you’ll needto read the text in the question tofigure out all of the variablesCan you think of how a questionmight quiz you on this informationwithout actually asking you to lookat a network diagram?Download at Boykma.Com
  10. 10. 320   Chapter 621. Answer: AThe organizational process assets contain historical information about past projects. When you write up yourlessons learned, or create work performance information, you store it in your company’s organizational processasset library! Also, did you notice that answer B was the wrong definition of parametric estimation?22. Answer: DCrashing the schedule is the form of schedule compression that increases cost. This is a difficult questionbecause all of the answers sound good, and one or two are a little misleading! Don’t fall into the trap ofchoosing an answer because you recognize a valid tool or technique in it. Reserve analysis and three-pointestimates are very useful techniques, but they’re not the answer to this question.23. Answer: BThe critical path is the path in the network diagram where any delay will cause a delay in the schedule. Theseare the activities that cannot slip without making the project late!24. Answer: CThis question was really about the definition of “duration,” and the key to answering it is to understand howduration is different from effort. The correct answer talks about “calendar time,” which is what a duration is: it’s ameasurement (or estimate) of how long the activity will take in real life, taking into account the number of peoplewho will be doing the work, the availability of the people and other resources, everyone’s vacation time, timetaken away from the schedule because people are pulled off of the activity to work on higher priority activities,and other real-world factors. That’s different from effort (which is often measured in person-hours), and it’sdifferent from resource estimating (which involves estimating how many people and what other resources willbe used for the activity).Exam QuestionsAnswersexam answersDownload at Boykma.Com
