1. Activity Definition 2 Activity sort 3 Activity Resource estimate 4 activity duration estimate 5 Schedule Schedule 6 Schedule Control

2. What is rolling planning?
Scrolling back-up is a form of representation that is planned to be completed in the near future to complete the work breakdown structure at the lowest level of detail planning, while the work of the decomposition structure is planned in the long-term work, in the work breakdown structure higher than the senior planning

3, what is the control account, planning portfolio?
The control account refers to the top management's control point can be located in the work breakdown structure work composition level above the selected management points. These control points are used as the basis for planning in the work mix of the upper planning

A planning mix is a component of a work breakdown structure that is under the control of an account in a work breakdown structure, but above the work mix. The purpose of this component is to plan the known work content of the non-detailed planning activities.

15, the key route method, if the total time difference is negative, how do you deal with it?
To make the total time difference of the route zero or positive, it is necessary to adjust the activity duration, logical relationship, time advance and lag, or other progress constraints

16, progress compression refers to what is the premise of shortening the progress time? What are the 2 kinds of technology? What are the drawbacks?
Reduce project progress time without changing project scope, schedule constraints, imposition dates, or other progress objectives.
1. Progress but will result in increased costs 2. Fast follow-up but often results in rework

17. What are the most commonly used techniques in scenario analysis?
Monte Carlo Analysis

18. What is the resource decision method? What is the resource allocation backward scheduling method? (in resource balancing)
The allocation of scarce resources to activities on key routes can be used to designate project schedules that reflect these constraints. The result of resource balance is often the estimated duration of the project than the preliminary project schedule.  This technique is sometimes called the resource decision method. Some projects may have limited but critical project resources that are encountered in this situation. Resources can be reverse-arranged from the end date of the project, which is called the resource allocation approach

19. What is resource constraint schedule? (In the Critical Chain method)
The key chain method combines the way of sex and randomness, starting with the non-conservative estimate of the duration of the activity in the progress model, drawing the project schedule Network diagram according to the given dependency and constraints, and then calculating the critical route. After determining the critical route, the project Schedule Network diagram is plotted based on the given dependencies and constraints, and then the critical routes are calculated.

20. What is the output of the progress benchmark? What is the output of the range datum? What is the output of the project benchmark? What is the output of the cost benchmark?
The progress benchmark is the output of the schedule, the scope datum is the output of the WBS, the project baseline is the output of the overall project management plan, and the cost base is the output of the cost management plan.

1. Variable cost 2. Fixed cost 3. Direct cost 4. Indirect costs

3. What is the definition of management reserve?
The management reserve is a single-column plan that comes out of the cost for future unforeseen times when it occurs. Management reserves contain cost or schedule reserves to reduce the risk of cheap cost or schedule objectives, and the use of management reserves requires changes to project baselines

4, the main steps of project cost estimation? Remember
1. Identify and analyze the constituent account of the cost 2. Estimate the cost per account based on the identified project cost composition account

6, the use of the analogy estimate of the premise?
Analogy estimation is an expert judgment that often requires insufficient understanding of the project situation, such as in the early stages of the project, similar to the substance of the previous project, not just superficially similar, and the individual or group with the required expertise

7, what is known unknown?? What is unknown and unknown? (in the reserve analysis)
Contingency reserve is an estimated cost that is freely used by the project manager to handle overdue but uncertain events. These events are called known unknown events. The management reserve is a budget reserved to deal with unplanned but potentially required project scope and cost changes called unknown unknowns.

8, the main steps of project cost budget? Remember
1. Allocate the total project cost to each work package for the project work breakdown structure

11, the main content of cost control? (9)
1. Impact on factors that cause cost benchmark changes
2. Ensure that the request for change is agreed
3. Manage these actual changes when a document change occurs
4. Ensure that potential cost overruns do not exceed authorized project stage funds and overall funding
5. Monitor cost performance and identify deviations from cost benchmarks
6. Accurately record all deviations from the cost benchmark
7. Prevent erroneous, inappropriate or unapproved changes from being included in the report on cost or resource use

EV earned value actual budgeted cost of work completed over a given time period
AC is the actual total cost of completion of work within a given time period
CV Cost Deviation SV Progress deviation CPI Cost Execution Index SPI Progress Execution index
BAC is budgeted as BAC when completed
ETC is required to complete the estimated EAC equals media to the current actual cost plus the new etc provided by the implementing organization

14, please explain the typical deviation, the meaning of the non-typical deviation?
The typical is good does not need to correct, atypical is bad need to correct,

15, the completion still need to estimate Etc=bac-ev, how to understand?
The current deviation is that the estimated value for completion is equal to the budgeted cost of the original completion minus the accumulated earned value of the present completion.

16, please do 2014 of the first half of the high afternoon exam questions two, and understand.

A: The beginning of the first week 100+55+35=190 million tenth week early 30+40+70 15th week early 20+40+60/(12/40) = 2.6 million

A 1: According to the capital investment plan: 1-4 weeks to perform a B 5 weeks to perform a B c 5-8 weeks execution A C 9 weeks c 10-11 weeks execution D
12-14 weeks of execution F 15-17 weeks Executive E F 18-20 weeks Executive G F

Answer 2:ac=100+55+35+190 pv=90+50+30+170 ev=90+50+30=170 cv=ev-ac=-20 million
Sv=ev-pv=0 Project cost overruns progress moderate

Answer 3:
ac=100+55+35+30+40=260 million
pv=90+50+30+30+60x (3/9) =260
ev=90+50+30+30+60x20%=212 million
CV=EV-AC=-48 million
Sv=ev-pv=-8 million
Project cost overruns, lagging progress

Answer 4: The existence deviation should be the typical way, the typical deviation calculation formula Etc=bac-ev cpi=
Eac=ac=etc
