Q

What is a master plan

A

a schedule of the major subsections or components of a project and lists the milestones from which a detail programme for the project is to be derived.

It shows a clear description of the projects deliverables and scope.

25
what are characteristics of an activity
*scheduled portion of work *have a series of actions *generally defined using a verb
26
What are advantages of using WBS
*improve estimating *better control of project execution *verify completion *can use historical information *template for future projects
27
What are critical path bar charts
a bar chart where all critical paths are highlighted
28
What is progress reporting
milestones are to be progressed and reported on in the project managers monthly/quarterly report
29
What are 5 of the 16 project management responsibilities
1. project integration management (PEP) 2. project scope management 3. project time management 4. project cost management 5. project quality management 6. project human resources management 7. project communication management 8. project risk management 9. project procurement management 10. project contract management 11. project financial management 12. project commissioning management 13. change control management 14. change close-out management 15. external project environment social requirements 16. document management
30
What does a schedule need to contain
*list of projects (from WBS) *duration of activities *order of activities *dependencies *significant milestones
31
Define duration
how long it will be from the activity starts until its completetion
32
Define effort
how many actual hours or days are spent on the task
33
What are tools and techniques for schedule development
*mathematical analysis *duration compression *simulation
34
What is mathematical analysis
calculating theoretical early and late starts, and completion dates of all project activities without regard for any resource pool limitations.
35
What is CPM? What does it involve?
Critical path method - calculates the float of a project to determine which activities have the least scheduling flexibility
36
What is PERT? What does it involve?
Program evaluation and review technique - average duration estimates to calculate project duration it uses an expected value
37
What is duration compression
Mathematical analysis to shorten the project scope
38
What are duration compression techniques
Crashing - cost and schedule trade off are made (not a good decisions usually results in increased cost) Fast tracking - perform activities in parallel (often results in rework and increases risk)
39
What do gannt charts show
Planned and actual progress for a number of tasks displayed over a horizontal time scale.
40
Is a WBS included in a gannt chart
Yes it is the breakdown of tasks on the left hand side
41
What are advantages of Gannt charts
*simple to construct *easy to understand *give a clear pictorial model
42
What are disadvantages of Gannt charts
*cannot easily show which activities are time critical *time slippage are difficult to assess *not easily updated
43
What is a project network diagram
A flow chart that graphically depict using nodes and arrows the sequence, interdependencies and start and finish times of the project job plan of activities
44
What are the rules for developing a project network
*left to right *all preceding activities need to be completed *arrows show flow *unique labels *larger number than preceding activities *looping not allowed *conditional statement not allowed
45
What are the types of activities in a network diagram
*burst - more than one activity immediately following *merge - two or more preceding activities *parallel - activities occur independently not necessarily at the same time
46
What are PERT or CPM mostly used for
PERT is mostly used for reasearch and development (R&D) CPM is mostly used for construction projects
47
What are advantages of critical path method
*ensures logical mining sequence *indicates how to complete activities *allocate resources for timely completion of the process
48
What are the 3 key components to build a CPM
1. list of all activities 2. time (duration) 3. dependencies
49
Define Activity
A specific task or set of tasks that are required by the project, use up resources, and take time to complete
50
Define Event
The result of completing one or more activities. An identifiable end state occurring at a particular time.
51
Define Start Node
This is a node that represents the beginning of the project.
52
Define Finish Node
This node represents the end of the project.
53
Define Immediate Predecessor
These are activities that must be completed by no later than the start time of the given activity
54
Define Immediate Successor
– Given the immediate predecessor of an activity, this activity becomes the immediate successor of each of these immediate predecessors. – If an immediate successor has multiple immediate predecessors, then all must be finished before an activity can begin.
55
Define Earliest start time of an activity (ES)
The time at which an activity will begin if there are no delays in a project.
56
Define Earliest finish time of an activity (EF)
The time at which an activity will finish if there are no delays in a project.
57
Define Latest start time of an activity (LS)
The latest possible time that an activity can start without delaying the project.
58
Define Latest finish time of an activity (LF)
The latest possible time that an activity can be completed without delaying the project.
59
Define Forward pass
The process of moving through a project from start to finish to determine the earliest start and finish times for the activities in the project.
60
Define Backward pass
The process of moving through a project from finish to start to determine the latest start and finish times for the activities in the project.
61
Define Slack for an activity
- The amount of time that a particular activity can be delayed without delaying the whole project. – It is calculated by taking the difference between the latest finish time with the earliest finish time.
62
Define Dummy activity
- to indicate interdependencies that cannot be represented correctly solely with the conventional activity and event structure – useful when doing hand solutions of the network for creating parallel activities or merging several parallel activities. – A dummy activity is used to maintain the network logic and to avoid ambiguity.
63
Define Earliest start time rule
The earliest start time for an activity is equal to the largest of the earliest finish times of its immediate predecessors.
64
Define Latest finish time rule
The latest finish time is equal to the smallest of the latest start times of its immediate successors
65
What is the procedure for obtaining earliest start
* Step 1: For the activity that starts the project, assign an earliest start time of zero, i.e., ES=0. * Step 2: For each activity whose ES has just been obtained, calculate its earliest finish time as ES plus duration of the activity. * Step 3: For each new activity whose immediate predecessors have EF values, obtain its ES by using the earliest start time rule. * Step 4:Apply step 2 to calculate EF. * Step 5: Repeat step 3 until ES and EF have been obtained for all activities including the finish node.
66
What is the procedure for obtaining latest start
* Step 1: For each of the activities that together complete the project, set its latest finish time equal to the earliest finish time of the finish node. * Step 2: For each activity whose LF value has just been obtained, calculate its latest start time as LS equals LF minus the duration of the activity. * Step 3: For each new activity whose immediate successors now have LS values, obtain its LF by applying the latest finish time rule. * Step 4:Apply step 2 to calculate its LS. * Step 5: Repeat step 3 until LF and LS have been obtained for all activities.
67
What is the critical path
defined those tasks for which the earliest time is equal to the latest time, it links tasks with zero float times
68
what is float time
difference between latest and earliest start times
