06-Time Management

Question 1

1. To control the schedule, a project manager is reanalyzing the project to predict project duration. She does this by analysing the sequence of activities with the least amount of scheduling flexibility. What technique is she using?
A.	Critical path method
B.	Flowchart
C.	Precedence diagramming
D.	Work breakdown structure

Answer 1

1. Answer A
   Explanation There are only two choices related to scheduling: critical path method and precedence diagramming. Precedence diagramming, however, is a diagramming technique that deals with the relationship between activities, not schedule flexibility. The project manager is analyzing the critical path.

Question 2

2. A dependency requiring that design be completed before manufacturing can start is an example of a(n):
A.	Discretionary dependency.
B.	External dependency.
C.	Mandatory dependency.
D.	Scope dependency.

Answer 2

2. Answer C
   Explanation No mention is made that the dependency comes from a source outside the project, so this is not an external dependency. Scope dependency is not a defined term. The key word in the question is “requiring.” Since the dependency is required, it could not be discretionary and therefore must be mandatory. The question defines a mandatory dependency.

Question 3

3. Which of the following are GENERALLY illustrated BETTER by bar charts than network diagrams?
A.	Logical relationships
B.	Critical paths
C.	Resource trade-offs
D.	Progress or status

Answer 3

3. Answer D
   Explanation The bar chart (or Gantt chart) is designed to show a relationship to time. This is best
   used when demonstrating progress or status as a factor of time.

Question 4

4. If the optimistic estimate for an activity is 12 days, and the pessimistic estimate is 18 days, what is the standard deviation of this activity?
A.	1
B.	1.3
C.	6
D.	3

Answer 4

4. Answer A
   Explanation The beta standard deviation is computed by (P - 0)/6. Therefore, the answer is
   (18 - 12)/6 = 6/6 = 1.

Question 5

5. A heuristic is BEST described as
A.	Control tool.
B.	Scheduling method.
C.	Planning tool.
D.	Generally accepted rule.

Answer 5

5. Answer D
   Explanation A heuristic is a generally accepted rule. Examples are cost per line of code, cost per square foot of floor space, etc.

Question 6

6. Lag means:
   A. The amount of time an activity can be delayed without delaying the project finish date.
   B. The amount of time an activity can be delayed without delaying the early start date of its successor.
   C. Waiting time.
   D. The product of a forward and backward pass.

Answer 6

6. Answer C
   Explanation Total float and free float are the time an activity can be delayed without impacting the entire project or the next activity. A forward or backward pass refers to a network analysis technique, not waiting time. Waiting time is the correct definition of lag.

Question 7

7. Which of the following is the BEST project management tool to use to determine the longest time the project will take?
A.	Work breakdown structure
B.	Network diagram
C.	Bar chart
D.	Project charter

Answer 7

7. Answer B
   Explanation The bar chart may show an end date, but it is not used to determine dates. The project charter also may include a required end date, but not a logical determination of how long the project will take. The network diagram takes the activities from the activity list and adds dependencies. The dependencies allow us to look at the various paths through the diagram to determine the longest duration (critical) path. The network diagram is the best answer.

Question 8

8. Which of the following is CORRECT?
   A. The critical path helps prove how long the project will take.
   B. There can be only one critical path.
   C. The network diagram will change every time the end date changes.
   D. A project can never have negative float.

Answer 8

8. Answer A
   Explanation This question tests your knowledge about a number of topics. There can often be more than one critical path, but you might adjust the plan in order to decrease risk and have only one critical path. The network diagram may or may not change when the end date changes, depending on the amount of schedule reserve and the reason for the change to the schedule. You can have negative float if you are behind schedule. The critical path helps prove how long the project will take. This is the only correct statement of the choices given.

Question 9

9. What is the duration of a milestone?
   A. It is shorter than the duration of the longest activity.
   B. It is shorter than the activity it represents.
   C. It has no duration.
   D. It is the same length as the activity it represents.

Answer 9

9. Answer C
   Explanation A milestone represents the completion of a series of activities or work packages. Therefore, it takes no time of its own.

Question 10

10. Which of the following BEST describes the relationship between standard deviation and risk?
    A. There is no relationship.
    B. Standard deviation tells you if the estimate is accurate.
    C. Standard deviation tells you how uncertain the estimate is.
    D. Standard deviation tells you if the estimate includes a pad.

Answer 10

10. Answer C
    Explanation An estimate can have a wide range and still he accurate if the item estimated includes identified risks. There is no such thing as a pad in proper project management. An estimate might be inflated, but it is a calculated reserve to account for risks, not arbitrary padding. The standard deviation tells you the amount of uncertainty or risk involved in the estimate for the activity.

Question 11

11. The float of an activity is determined by:
    A. Performing a Monte Carlo analysis.
    B. Determining the waiting time between activities.
    C. Determining lag.
    D. Determining the length of time the activity can be delayed without delaying the critical path.

Answer 11

11. Answer D
    Explanation The total float of an activity is the length of time the activity can be delayed without delaying the critical path.

Question 12

12. A project has three critical paths. Which of the following BEST describes how this affects the project?
A.	It makes it easier to manage.
B.	It increases the project risk.
C.	It requires more people.
D.	It makes it more expensive.

Answer 12

12. Answer B
    Explanation Though having three critical paths COULD require more people or cost more, the answer that is definitely and always true is that it increases project risk. Because you need to manage three critical paths, there is more risk that something could happen to delay the project.

Question 13

13. If project time and cost are not as important as the number of resources used each month, which of the following is the BEST thing to do?
A.	Perform a Monte Carlo analysis.
B.	Fast track the project.
C.	Perform resource optimization.
D.	Analyze the life cycle costs.

Answer 13

13. Answer C
    Explanation Fast tracking affects both time and cost but may not help even out resource usage. Monte Carlo analysis and analysis of life cycle costs do not directly deal with resources. Resource optimization is the only choice that will definitely affect resources.

Question 14

14. When is a milestone chart used instead of a bar chart?
A.	Project planning
B.	Reporting to team members
C.	Reporting to management
D.	Risk analysis

Answer 14

14. Answer C
    Explanation Both types of charts are used in project planning. Team members need to see details and so they need a bar chart rather than a milestone chart. Risk analysis COULD make use of both charts. A milestone chart is used instead of a bar chart for any situation where you want to report in a less detailed way. Since bar charts can scare people with their complexity and often show too much detail to be worthwhile on a management level, milestone charts are more effective for reporting to management.

Question 15

15. Your project management plan results in a project schedule that is too long. If the project network diagram cannot change but you have extra personnel resources, what is the BEST thing to do?
A.	Fast track the project.
B.	Level the resources.
C.	Crash the project.
D.	Perform Monte Carlo analysis.

Answer 15

15. Answer C
    Explanation Leveling resources generally extends the schedule. Monte Carlo analysis does not directly address the constraints of this situation. To compress the schedule, you could either crash or fast track. However, the situation says that the network diagram cannot change. This eliminates the fast tracking option, leaving crashing the project as the best answer.

Question 16

16. Which of the following is the BEST thing to do when asked to complete a project two days earlier than planned?
    A. Tell senior management that the project’s critical path does not allow the project to be finished earlier.
    B. Tell your boss.
    C. Meet with the team to look at options for crashing or fast tracking the critical path.
    D. Work hard and see what the project status is next month.

Answer 16

16. Answer C
    Explanation This is another question that asks about problem solving. Neither telling the boss nor waiting to see the status next month tries to solve the real problem. It would be inaccurate to report that the project cannot be finished earlier. Only meeting with the team to look for options for compressing the schedule (by crashing or fast tracking) relates to problem solving.

Question 17

17. In attempting to complete the project faster, the project manager looks at the cost associated with crashing each activity. The BEST approach to crashing would also include looking at the:
    A. Risk impact of crashing each activity.
    B. Customer’s opinion of which activities to crash.
    C. Boss’s opinion of which activities to crash and in which order.
    D. Project life cycle phase in which the activity is due to occur.

Answer 17

17. Answer A
    Explanation You may or may not need your customer’s or your boss’s input, but you will definitely need to include an analysis of risk.

Question 18

18. Which of the following processes includes asking team members about the time estimates for their activities and reaching agreement on the calendar date for each activity?
A.	Sequence Activities
B.	Develop Schedule
C.	Define Scope
D.	Develop Project Charter

Answer 18

18. Answer B
    Explanation By the time this process is taking place, Develop Project Charter, Define Scope, and Sequence Activities would be completed. The process defined in the question is Develop Schedule.

Question 19

19. A project manager is in the middle of executing a very large construction project when he discovers the time needed to complete the project is longer than the time available. What is the BEST thing to do?
    A. Cut product scope.
    B. Meet with management and tell them the required date cannot be met.
    C. Work overtime.
    D. Determine options for schedule compression and present management with his recommended option.

Answer 19

19. Answer D
    Explanation This question again tests whether you know how to solve problems. Cutting product scope negatively affects the customer, and is therefore not best. A project manager’s job is to determine options for meeting any end date; therefore, simply telling management the required date cannot be met is not correct. Working overtime is expensive and unnecessary when there are many other choices that could be selected first. Determining options for schedule compression would have the least negative effect on the project.

Question 20

20. During project planning, you estimate the time needed for each activity and then add up the estimates to create the project estimate. You commit to completing the project by this date. What is wrong with this scenario?
    A. the team did not create the estimate, and estimating takes too long using that method.
    B. The team did not create the estimate, and a network diagram was not used.
    C. The estimate is too long and should be created by management.
    D. The project estimate should be the same as the customer’s required completion date.

Answer 20

20. Answer B
    Explanation Time estimates for the activities should be created by the team and should not be added together to create the project estimate. Some activities may take place concurrently; these would be identified in the network diagram.

Question 21

21. You are a project manager on a US $5,000,000 software development project. While working with your project team to develop a network diagram, you notice a series of activities that can he worked in parallel but must finish in a specific sequence. What type of activity sequencing method is required for these activities?
A.	Precedence diagramming method
B.	Arrow diagramming method
C.	Critical path method
D.	Operational diagramming method

Answer 21

21. Answer A
    Explanation The question implies a finish-to-finish relationship between activities. The arrow diagramming method does not support that type of relationship. Critical path is not a diagramming method, and operational diagramming method is a made-up term. The precedence diagramming method is most appropriate in this case.

Question 22

22. You are a project manager on a US $5,000,000 software development project. While working with your project team to develop a network diagram, your data architects suggest that quality could be improved if the data model is approved by senior management before moving on to other design elements. They support this suggestion with an article from a leading software development journal. Which of the following BEST describes this type of input?
A.	Mandatory dependency
B.	Discretionary dependency
C.	External dependency
D.	Heuristic

Answer 22

22. Answer B
    Explanation The situation is neither mandatory nor driven by an external source. A heuristic is a general rule that can be used consistently. This situation is a unique occurrence for which a preferred method is being suggested. Therefore, this is a discretionary dependency.

Question 23

23. Based on the following, if you needed to shorten the duration of the project, which activity would you try to shorten?
A.	Activity B
B.	Activity D
C.	Activity H
D.	Activity C

Answer 23

23. Answer D
    Explanation This is an example of a two-stage question you may find on the exam. First you need to draw the network diagram and find the critical path, and then make a decision. The network diagram would be:

The critical path is 16 (Start, C, E, H, End). Many people immediately look for the longest duration activity on the project to cut. Here activity D is the longest, at 10 weeks. However, that activity is not on the critical path, and cutting it would not shorten the project’s duration. You must change the critical path. In this case, both activity C and activity II are on the critical path. If you have a choice, all things being equal, choose the earlier option. Therefore, activity C is the best answer.

Question 24

24. You have a project with the following activities: Activity A takes 40 hours and can start after the project starts. Activity B takes 25 hours and should happen after the project starts. Activity C must happen after activity A and takes 35 hours. Activity D must happen after activities B and C and takes 30 hours. Activity E must take place after activity C and takes 10 hours. Activity F takes place after Activity E and takes 22 hours. Activities F and D are the last activities of the project. Which of the following is TRUE if activity B actually takes 37 hours?
    A. The critical path is 67 hours.
    B. The critical path changes to Start, B, D, End.
    C. The critical path is Start, A, C, E, F, End.
    D. The critical path increases by 12 hours.

Answer 24

24. Answer C
    Explanation Did you notice how difficult this question was to read? Such wording is intentional, to prepare you for interpreting questions on the real exam. Looking at this situation, you see there are three paths through the network as shown in the following table. If the duration of activity B changes from 25 to 37, the activity will take 12 hours longer. As the activity is only on the third path, it will only change the duration of that path from 55 to 55 + 12, or 67 hours. Since the duration of the critical path is 107 hours, the delay with activity B will have no impact on the project timeline or the current critical path.

Start, A, C, E, F, End 107
Start, A, C, D, End 105
Start, B, D, End 55

Question 25

25. A project manager has received activity duration estimates from his team. Which of the following does he need in order to complete the Develop Schedule process?
A.	Change requests
B.	Schedule change control system
C.	Recommended corrective actions
D.	Reserves

Answer 25

25. Answer D
    Explanation The Develop Schedule process includes all work and uses all inputs needed to come up with a finalized, realistic schedule. As part of the Estimate Activity Durations process, reserves are created to cover identified and unknown schedule risks. All the other items are parts of Control Schedule and occur after the Develop Schedule process.

Question 26

26. A project manager is taking over a project from another project manager during project planning. If the new project manager wants to see what the previous project manager planned for managing changes to the schedule, it would be BEST to look at the:
A.	Communications management plan.
B.	Update management plan.
C.	Staffing management plan
D.	Schedule management plan.

Answer 26

26. Answer D
    Explanation The schedule management plan is the most correct answer. It includes plans for how schedule changes will be managed.

Question 27

27. A project manager is using weighted average duration estimates to perform schedule network analysis. Which type of mathematical analysis is being used?
A.	Critical path method
B.	Beta distribution
C.	Monte Carlo
D.	Resource leveling

Answer 27

27. Answer B

Explanation Beta distribution uses weighted averages to compute activity durations.

Question 28

28. The WBS, estimates for each work package, and the network diagram are completed. The NEXT thing for the project manager to do is:
    A. Sequence the activities.
    B. Validate that they have the correct scope.
    C. Create a preliminary schedule and get the team’s approval.
    D. Complete risk management.

Answer 28

28. Answer C
    Explanation Sequencing the activities is the same thing as creating a network diagram, so that has already been done. The Validate Scope process is done during project monitoring and controlling, not during project planning. Since a schedule is an input to risk management, risk management comes after the creation of a preliminary schedule, and so that is not the “next thing to do:’ Creating the preliminary schedule is next.

Question 29

29. A new product development project has four levels in the work breakdown structure and has been sequenced using the precedence diagramming method. The activity duration estimates have been received. What should be done N EXT?
A.	Create an activity list.
B.	Begin the work breakdown structure.
C.	Finalize the schedule.
D.	Compress the schedule.

Answer 29

29. Answer D
    Explanation The question is really asking, “What is done after the Estimate Activity Durations process?” The work breakdown structure and activity list are done before Estimate Activity Durations. The schedule is not finalized until after schedule compression. Therefore compressing the schedule is done next.

Question 30

30. You are the project manager for a new product development project that has four levels in the work breakdown structure. The network diagram and duration estimates have been created, and a schedule has been developed and compressed. Which time management activity should you do NEXT?
A.	Control Schedule.
B.	Estimate Activity Resources.
C.	Analogously estimate the schedule.
D.	Gain approval.

Answer 30

30. Answer D
    Explanation Notice how this question and the previous one seem very similar. This is intended to prepare you for similar questions on the exam. Estimating activity resources and analogously estimating the schedule should have already been completed. The situation described is within the Develop Schedule process of time management. Control Schedule is the next time management process after Develop Schedule, but the Develop Schedule process is not yet finished. Final approval of the schedule by the stakeholders is needed before one has a project schedule.

Question 31

31. A team member from research and development tells you that her work is too creative to provide you with a fixed single estimate for the activity. You both decide to use the average labor hours to develop a prototype (from past projects). This is an example of which of the following?
A.	Parametric estimating
B.	Three-point estimating
C.	Analogous estimating
D.	Monte Carlo analysis

Answer 31

31. Answer A
    Explanation Monte Carlo analysis is a modeling, or simulation, technique. Three-point estimating uses three time estimates per activity. One could use data from past projects to come up with the estimate (analogous estimating), but the best answer is parametric estimating because past history is being used to calculate an estimate.

Question 32

32. An activity has an early start (ES) of day 3, a late start (LS) of day 13, an early finish (EF) of day 9, and a late finish (LF) of day 19. The activity:
A.	Is on the critical path.
B.	Has a lag.
C.	Is progressing well.
D.	Is not on the critical path.

Answer 32

32. Answer D
    Explanation There is no information presented about lag or progress. The activity described has float, because there is a difference between the early start and late start. An activity that has float is probably not on the critical path.

Question 33

33. The project is calculated to be completed four days after the desired completion date. You do not have access to additional resources. The project is low risk, the benefit cost ratio is expected to be 1.6, and the dependencies are preferential. Under these circumstances, what is the BEST thing to do?
    A. Cut resources from an activity.
    B. Make more activities concurrent.
    C. Move resources from the preferential dependencies to the external dependencies.
    D. Remove an activity from the project.

Answer 33

33. Answer B
    Explanation Cutting resources from an activity would not save time, nor would moving resources from the preferential dependencies to the external dependencies. Removing an activity from the project is a possibility, but since the dependencies are preferential and the risk is low, the best choice is to make more activities concurrent, as this would have less impact on the project.

Question 34

34. A project manager for a small construction company has a project that was budgeted for US $130,000 over a six-week period. According to her schedule, the project should have cost US $60,000 to date. However, it has cost US $90,000 to date. The project is also behind schedule, because the original estimates were not accurate. Who has the PRIMARY responsibility to solve this problem?
    A. Project manager
    B. Senior management
    C. Project sponsor
    D. Manager of the project management office

Answer 34

34. Answer A
    Explanation Did you get lost looking at all the numbers presented in this question? Notice that there are no calculations required, simply an understanding of what the problem is. This question describes schedule management, which is a responsibility of the project manager.

Question 35

35. Senior management is complaining that they are not able to easily determine the status of ongoing projects in the organization. Which of the following types of reports would help provide summary information to senior management?
A.	Detailed cost estimates
B.	Project management plans
C.	Bar charts
D.	Milestone reports

Answer 35

35. Answer D
    Explanation Detailed cost estimates have nothing to do with the situation described. Project management plans include more detail than is necessary for the situation described, and may distract from the conversation if used in this situation. Bar charts are most effective for reporting to the team. The best answer is milestone reports, which present the right level of detail for upper management.

Question 36

36. Rearranging resources so that a constant number of resources is used each month is called:
A.	Crashing.
B.	Floating.
C.	Leveling.
D.	Fast tracking.

Answer 36

36. Answer C
    Explanation The key to this question is the phrase “constant number used each month.” Only leveling has such an effect on the schedule.

Question 37

37. Which of the following is a benefit of an analogous project estimate?
    A. It will be closer to what the work will actually require.
    B. It is based on a detailed understanding of what the work requires.
    C. It gives the project team an understanding of management’s expectations.
    D. It helps the project manager determine if the project will meet the schedule.

Answer 37

37. Answer C
    Explanation Remember that analogous project estimates are considered to be top-down, high-level estimates. Therefore, they are not based on a detailed understanding of what the work will require. The project manager needs more than an analogous (high-level) estimate to determine whether or not the project will meet the schedule. The benefit of an analogous project estimate is that it is management’s expectations of how long the project will take. Any differences between the analogous estimate and the detailed bottom-up estimate can be reconciled in the planning processes.

Question 38

38. During project executing, a large number of changes are made to the project. The project manager should:
    A. Wait until all changes are known and print out a new schedule.
    B. Make approved changes as needed, but retain the schedule baseline.
    C. Make only the changes approved by management.
    D. Talk to management before any changes are made.

Answer 38

38. Answer B
    Explanation Waiting until all changes are known, and then printing out a new schedule, is a common error many project managers make. Instead, the project manager should be controlling the project throughout its completion. The situation in the question does not provide a reason to believe the schedule baseline must be changed. A project manager must be in control of the project, rather than consulting with management before making any changes. Whenever a large number of changes occur on a project, it is wise to confirm that the business case, as stated in the project charter, is still valid.

Question 39

While planning the schedule for your project, you frequently refer to the project calendar. The project calendar is:
A. A calendar containing the days on which various meetings are scheduled within the project team.
B. A calendar of working days or shifts that establishes those dates on which schedule activities are worked.
C. A calendar containing the list of days on which the project team members will be on leave or take an “off”.
D. A calendar that establishes the dates on which project deliverables are sent to the customer.

Answer 39

B - A project calendar is a calendar of working days or shifts that establishes those dates on which schedule activities are worked. It also establishes non-working days that determine dates on which schedule activities are idle, such as holidays, week-ends and non-shift hours. [PMBOK 5th edition, Page 184] [Project Time Management]

Question 40

As a project manager, you are in the process of preparing the project schedule for the project. Which of the following accurately depicts the sequence of your activities before you begin preparing the project schedule?
A. Sequence Activities, Estimate Activity Resources, Estimate Activity Durations
B. Sequence Activities, Estimate Activity Durations, Estimate Activity Resources
C. Estimate Activity Durations, Sequence Activities, Estimate Activity Resources
D. Estimate Activity Resources, Estimate Activity Durations, Sequence Activities

Answer 40

A - The correct sequence of processes in the Time Management Knowledge Area is: Plan Schedule Management, Define Activities, Sequence Activities, Estimate Activity Resources, Estimate Activity Durations, Develop Schedule and Control Schedule. [PMBOK 5th edition, Page 141] [Project Time Management

Question 41

After one year of construction, an office building is scheduled to be completed on 30th January. The landscaping work needs to start 15 days prior to completion of the building. Which of the following relationships most likely represents the relationship of the start of landscaping work to the completion of the office building?
A.	Finish-to-start with a 15 day lead
B.	Start-to-finish with a 15 day lead
C.	Finish-to-start with a 15 day lag
D.	Start-to-finish with a 15 day lag

Answer 41

A - The landscaping work needs to start on completion of the office building, so it is a finish-to-start relationship. Since it needs to start 15 days before completion of the building, it requires a lead of 15 days. Hence the answer is finish-to-start with a 15 day lead. [PMBOK 5th edition, Page 156] [Project Time Management]

Question 42

You are the project manager of a project. As part of the planning process, you utilize a planning technique to subdivide the project scope and deliverables into smaller, more manageable components. What is this technique called?
A.	Unit task analysis
B.	Decomposition
C.	Rolling wave planning
D.	Arrow Diagramming Method

Answer 42

B - Decomposition is the correct response. [PMBOK 5th edition, Page 151] [Project Time Management]

Question 43

The accuracy of Activity Duration estimates can be improved by considering the amount of risk in the original estimate. The three types of estimates on which three-point estimates are based are:
A. Budgetary, ballpark, and Order of Magnitude.
B. Best case scenario, expected scenario and current scenario.
C. Most likely, likely and unlikely
D. Most likely, optimistic, and pessimistic

Answer 43

D - The accuracy of Activity Duration estimates can be improved by considering the amount of risk in the original estimate. The three types of estimates on which three-point estimates are based are: Most likely, Optimistic, and Pessimistic. An Activity Duration can be created using a value derived from these three estimated durations. [PMBOK 5th edition, Page 170] [Project Time Management]

Question 44

You have decided to apply Resource Leveling to a project due to a critical required resource being available only at certain times. Which of the following will likely be true?
A. Resource Leveling can often cause the original critical path to change.
B. Resource Leveling will over allocate resources to schedule the project before the deadline.
C. Resource Leveling will require additional resources to complete the project.
D. Resource Leveling will never alter the original critical path

Answer 44

A - Resource Leveling can often cause the original critical path to change. [PMBOK 5th edition, Page 179] [Project Time Management]

Question 45

Bar charts, with bars representing activities, show activity start dates as well as end dates and expected activity durations. For control and management communication, the broader, more comprehensive summary activity that is used between milestones is referred to as:
A.	Activity bridge
B.	Milestone chart
C.	Hammock activity
D.	Gantt chart

Answer 45

C - The correct response is the Hammock activity. The comprehensive summary activity that is displayed in bar chart reports for control and management communication is called Hammock activity. [PMBOK 5th edition, Page 182] [Project Time Management]

Question 46

A technique that iterates the project schedule many times, to calculate a distribution of possible project completion dates is called:
A.	Monte Carlo Analysis
B.	Monteford analysis
C.	Pareto Cost chart
D.	Deming Analysis

Answer 46

A - Monte Carlo Analysis is a technique that computes, or iterates, the project cost, or the project schedule many times using input values selected at random from probability distributions of possible costs or durations, to calculate a distribution of possible total project costs or completion dates. [PMBOK 5th edition, Page 180, 340] [Project Time Management]

Question 47

The critical path method (CPM) calculates the theoretical early start and finish dates; and late start and finish dates. The difference between the late and early start of a task is called:
A.	Free float
B.	Feeding buffer
C.	Danger zone
