Q

Some short comings of PDM

A

All goals are based on estimates, which contain uncertainties
* Estimates of activity times generally include a large safety margin
* ‘Student syndrome’ may operate: human nature for many of us means
activities are left to the last possible minute
* ‘Parkinson’s Law’ may prevail: an activity will expand to fill the time
available
* The way that progress is measured is in error – by the time the PM is
notified of a problem it is already too late to prevent it!

54
Q

. Perform the upward pass

A

Identify potential critical path and activity segments

The goal of the upward pass is to determine which activities or portions of activities
could potentially be controlling. This will be verified with the downward pass.

55
Q
  1. Perform the downward pass
A

Verify critical path and activity segments
The purpose of the downward pass
is to determine which portions of
the potential controlling segments
are actually on the controlling
activity path

56
Q

Lowest Price Conforming (LPC):

A

The contract is awarded to the lowest price bidder provided it conforms. The attributes of the other bidders
are discarded or returned

The beauty of this method is that it does not allow value decisions on which bidder’s attributes are better
than the others. The decision is cut and dried. For this reason, LPC should only be used for contracts that are
low in value, where the scope/Risk is tightly defined

57
Q

Weighted Attributes

A

t, assessing attributes and price with varying weightings to determine a
preferred bidder for cost and quality optimization.

This method lacks transparency regarding trade-offs between price and non-price components, potentially
leading to unexpected outcomes.

58
Q

Target Price [Purchaser Nominated Price]:

A

Here’s the process (or similar):
1. The client sets a budget clearly outlined in the RFP and specifies the desired outcomes.
2. Suppliers describe their proposed solutions based on weighted evaluation criteria.
3. Bids are scored, and the winner is determined using the weighted attributes method, without the need for
a price score.

This straightforward yet robust approach ensures optimal value within a set budget, resembling the method
employed when purchasing a home, car, or significant asset—where you know your budget limit and strive
for the best possible value within those constraints.”

59
Q

The Price Quality Method:

A

Like weighted attributes, the Price/Quality method starts by setting weights for the attributes and the price. At
that point, before the RFT is released, it’s possible to review the Supplier Quality Premium (SQP) that is
assigned to each attribute point. This is a dollar value that corresponds to the amount that the client is
prepared to pay for each attribute point that one bidder scores higher than another. It’s a perfect ‘reality
check’ for clients to consider, alongside the potential material impact of risks on the project and/ or the value
that innovations might deliver to the project or the asset in future.

60
Q

Quality-Based Selection, or Brook’s Law:

A

This approach is applicable when project scope is uncertain, pricing is challenging to estimate, or when a high
degree of cooperation between the client and supplier(s) is essential for successful project delivery (common
in Alliance or Public-Private Partnership projects).

This method doesn’t involve pricing; instead, it focuses on a list of attributes defining the desired qualities in a
supplier or group of suppliers. Often, complex mechanisms are used in conjunction with this evaluation
method to quantify risks and conduct a thorough cost/benefit analysis of proposed solutions.

61
Q

Schedule of Values (SOV

A

The SOV is used in the measurement process for determining what work has been accomplished or
earned.

62
Q

Planned Value (PV)

A

The value of the work planned or scheduled to be accomplished within a specific time period as illustrated in the schedule. This is
also known as the Budgeted Cost for Work Scheduled (BCWS).

63
Q

Earned Value (EV

A

The value of the work completed measured in terms of the planned value of the work. It is the earned value for a task and a principle
measurement in the Earned Value Management process. This is also known as the Budgeted Cost for Work Performed (BCWP).

64
Q

Actual Cost (AC)

A

The actual cost incurred in the performance of the work for a given time period. It is one of the principle measurement tools of project
control. This is also known as the Actual Cost of Work Performed (ACWP)。

65
Q

Cost Variance (CV)

A

Difference (in dollars) between what was
earned in performing the task(s) and what it
actually costs to perform the task.
CV = Earned Value – Actual Cost
CV = BCWP – ACWP

65
Q

Schedule Variance (SV)

A

Difference (in dollars) between what was
planned on being earned and what was actually
earned for a task(s).
SV = Earned Value – Planned Value
SV = BCWP – BCW

66
Q

Schedule Performance Index (SPI

A

The budgeted cost of work performed
(BCWP) divided by the budgeted cost of
work scheduled (BCWS). It is a ratio of the
earned value to the planned value
SPI = BCWP/BCWS
SPI = EV/PV

67
Q

What is CPI cost performance index

A

The budgeted cost of work performed
(BCWP) divided by the actual cost of the work
performed. It is a ratio of the earned value to
the actual cost.
CPI = BCWP/ACWP
CPI = EV/AC

68
Q

Estimate at Completion (EAC)

A

The total anticipated cost of the project when it is complete. Thus, it allows
the project manager to see what the final project cost estimate is.
EAC = BAC ÷ CPI

69
Q

Estimate to Completion (ETC)

A

for determining the amount of money required to complete the task (or project) if
conditions remain as is.
ETC = EAC - AC
what is the cash requirement to complete the work?

70
Q

Variance at Completion (VAC)

A

The expected cost variance at the end of the project

VAC = BAC - EAC

A positive VAC tells the project team that the costs are under budget.
* A negative VAC tells the project team that the costs have exceeded the current target budget.

71
Q

To-Complete Performance Index (TCPI)

A

It computes the future required cost efficiency needed to achieve a target Estimate at Completion (EAC).
* TCPI answers the question of “how efficiently must we use our remaining resources (financial)?”
For TCPI greater than 1.00, there is more work remaining than there is budget to pay for it.
TCPI less than 1.00 indicates that there will be surplus funds in the budget after the work has been
completed.

1.2 cpi may be too high

72
Q

Delay Claims

A

A ‘claim’ is a request from one contract party (usually the contractor) to another
party for additional compensation, an extension of time, or both.

73
Q

A ‘claim’ is a request from one contract party (usually the contractor) to another
party for additional compensation, an extension of time, or both.

A

Also know as “Budget creep” occurs when a project’s costs increase beyond the
original budget. Unexpected changes, organizational mismanagement, or unrealistic
estimates can cause it.

74
Q

Excusable delay

A

An excusable delay entitles the contractor to additional time for completing
the contact work
beyond the contractor’s control.

75
Q

Non-excusable delay

A

Typically, a non-excusable delay is any delay that is either caused by the contractor or not
under normal conditions but should have been anticipated by the contractor under normal
conditions.
A non-excusable delay does not entitle the contractor to either a time extension or
monetary compensation.

76
Q

What are liquidated damages?

A

Liquidated damages are not penalties, they are pre-determined damages set at the time that a contract is entered into,
based on a calculation of the actual loss the client is likely to incur if the contractor fails to meet the completion date.
They are generally set as a fixed daily or weekly sum

Liquidated damages might include:
Loss of rent. Loss of income. Fees. Storage costs. Rental costs. Fines imposed by third parties. Financing costs.

77
Q

Concurrent delay

A

A combination of two or more independent causes of delay during the same general time period
may be considered to be concurrent delays.

78
Q

There are two types of concurrent delay:

A

‘true concurrency’.
two or more delay events occur at the same time, one a Client Risk Event, and
the other a Contractor Risk Event, and the effects of these events on the project are felt at the same
time”.

‘concurrent effect of sequential delay events

where two or more delay events occur at different times, but the delay effects of
each overlap.

79
Q

Accelerating a project

A

Accelerating a project means shortening the normal duration of the project schedule without
reducing the original scope of work. It also called schedule compression.

80
Q

Normal duration

A

We define normal duration for a specific contractor as the amount of time required to finish the
project under ordinary circumstances without any deliberate acceleration or deceleration

81
Q

Why need for time reduction?

A

Recover schedule and meet important project target dates
The contractor may desire an earlier completion date
Early completion bonus

82
Q

Mandatory dependencies

A

Mandatory dependencies are those that are legally or contractually required or inherent in the nature of the
work. Mandatory dependencies often involve physical limitations

Mandatory dependencies are sometimes referred to as hard logic or hard dependencies.

83
Q

Discretionary dependencies

A

Discretionary dependencies are referred to as preferred logic, preferential logic, or soft logic.
Discretionary dependencies are established based on knowledge of best practices within a particular application area
or some unusual aspect of the project where a specific sequence is desired, even though there may be other
acceptable sequences.

84
Q

Constructability

A

defined as “the optimum use of construction knowledge and experience
in planning, design, procurement, and field operations to achieve overall project objectives

85
Q

What is the
definition of
Risk?

A

Risk is a combination of (i) events A and the consequences of these events C, and
(ii) the associated uncertainties U (about what will be the outcome)

87
Q

Fault Tree Analysis (FTA

A

FTA is a system analysis technique used to determine the root causes and probability of
occurrence of a specified undesired event.
Deductive, it transverses from the general problem to the specific causes.

88
Q

Cut sets

A

set of events that together cause the top undesired event to occur

89
Q

Reactive FTA

A

Performed after an accident has occurred.
* Used as an accident investigation method

90
Q

Proactive FTA

A

Performed during system development to influence design
by predicting and preventing future problems
* Used as risk analysis method

91
Q

Event Tree Analysis (ETA)

A

An event tree analysis (ETA) is an inductive procedure that shows all possible outcomes
resulting from an accidental (initiating) event, taking into account whether installed safety barriers
are functioning or not, and additional events and factors.
ETA can be used to identify all potential accident scenarios and sequences in a complex
system.

92
Q

What are Markov Chains?

A

Markov chains are used to compute the probabilities of events occurring by viewing them as states
transitioning into other states, or transitioning into the same state as before

93
Q

Pre-posterior Analysis

A

A decision is ‘sensitive’ if
* after a test the decision is different for different test results;
* after more tests, the decision changes
Sensitivity of the decision will tend to reduce with the increase in
number of tests.
One can do a test, incur the cost of that test, and then make a decision
to take a particular action or do another test.

94
Q

what is a type 1 error

A

Rejecting a true Hypothesis

95
Q

what is a type 2 error

A

96
Q

Utility

A

Utility (U) is defined as the state of being satisfied ,useful, valuable, profitable, having worth or beneficia

97
Q

Marginal utility (MU)

A

is defined as the additional utility gained from the consumption of one additional unit of
a good or service.

98
Q

Total utility (TU) i

A

Total utility (TU) is defined as the total amount of satisfaction that a person/decision maker can receive from
the consumption of all units of a specific product or service

99
Q

The Utility Maximisation rule states:

A

Decisionmakers decide to allocate their money incomes so that the last dollar spent on each product
purchased yields the same amount of extra marginal utility.

Utility Maximization model is built based on the following assumptions:
1.Decision-makers are assumed to be rational (trying to get the most value for their money)
2.Decision-makers’ incomes are limited because their individual resources are limited(budget constraint)
3.Decision-makers have clear preferences for various goods and services.(thus they know their MU)
4.Decision-makers must choose among alternative goods with their limited incomes/resources.

100
Q

Deterioration modelling

A

Deterioration modelling involves the modelling and prediction of the
physical state of equipment, structures, infrastructure, or any tangible
assets.
forming the foundation for decisions related to
maintenance and rehabilitation

100
Q

Individual Risk Appetite i,e explain risk neutral, averse and anot risk averse

A

A ‘risk neutral’ person bases all decisions on expected utility.
* A ‘risk averse’ person will be uncomfortable with a small p* (i.e.
large probability of big loss).
* A ‘not risk averse’ person will be comfortable with a small p* (i.e. a
small probability of a big win

101
Q

what’s the difference between Outputs, Outcomes and
Benefits

A

outputs = tangible product or process from the project. enables a new outcome in part of operational organisation.
outcomes = desired operational result derived from delivery of an output
benfits = measurable gain to a stakeholder resulting from an outcome or part of an outcome

102
Q

what should all asset management descions have in common?

A

policy driven, performance based, options evaluated, descions based on quality information, clear accountability

103
Q

What is a Business Case?

A

A business case provides justification for undertaking a project. It
evaluates the benefits, costs and risks of alternative options and
presents the rationale for the preferred solution. Its purpose is to
obtain management commitment and approval for the investment or
funding”

104
Q

the areas of main concern in IAM are:

A

that there is limited knowledge and information available on the condition of assets;
▪ that present financial provisions may be insufficient to meet long-term expenditure
requirements for capital maintenance and eventual replacement of assets;
▪ that asset valuation provides a statement of current replacement cost and depreciated
value, but only provides a rough indication of the size of likely problems, rather than the
sort of accurate information required;
▪ that methods used to determine renewal expenditure must reflect the way assets are
“consumed” over time;
▪ that Operators need to be able to apply a long-term perspective to the issue of asset
management to ensure no undue burden is borne by one generation over another.

Q

Independent Systems

A

Do not share any processes or data

106
Q

Interfaced Systems

A

Simply connected systems or subsystems
that can exchange information across the common boundary
which they share. Systems share data but no processes

107
Q

Interoperable Systems

A

Provide and accept services from other
systems and use the services exchanged to enable them to
operate effectively together. Systems share limited processes and
data

108
Q

Integrated Systems

A

Tightly coupled interconnection of
different, highly specialized devices, subsystems or systems, into a
broader system providing complex functions which require close
interactions between it’s components. Systems share many
processes and data.

109
Q

what is the equation of a good decision?

A

expected value = odds of gain * value of gain

110
Q

ALLAIS’ PARADOX

A

This involves calculating the expected utility of each action and
choosing the action with the maximum expected utility. However,
it has been found that decision makers do not always do this

111
Q

Brute force with weighted expert opinion
Simple MCA advantges and disadvanteges

A

Disadvantages:
* -Weighting factors are often difficult to agree on by many parties.
* -There may be inconsistencies within weighting factors (discussed later on
in the lecture).
Advantages: Fast and dirty approach.

112
Q

Risk Based approach

A

Technique that uses Risk = Probability x Consequence to
identify high risk areas that should be addressed.
* Risk is often used to balance the funding gap. Understanding
this gap will lead to better decision making.
Advantages:
* Based on Mathematical Decision Theory and is an industry
standard
* Generates ratio data
Disadvantages:
* Labour intensive
* Participants perceive the tool as a ‘black box’ if they do not
understand the mathematical theory

113
Q

Analytical Hierarchy Process (3)

A

define objective
structure elements
make pair wise comparisons
: Calculate criteria weights vector {W} Normalized Matrix (below
Complete a consistency check
Evaluate alternatives according to weightin

114
Q

Delphi Method

A

Delphi method is a structured communication technique that seeks to
minimize variance.
* Based on the principle that decisions form a structured group of individuals is
more accurate than those from unstructured groups.
* Based on the assumption that group judgments are more valid than individual
judgments.
* It requires a panel of experts.
The experts answer questionnaires in two or more rounds.
* After each round, a facilitator provides an anonymous summary of the experts’ decisions from
the previous round as well as the reasons for their judgments.
* In the next round, experts are encouraged to revise their earlier answers in light of the replies
of other members of their panel.
* Finally, the process is stopped after a predefined stop criterion (e.g. number of rounds,
achievement of consensus, stability of results

115
Q

Cognitive Fluency

A

How easy an idea is to process and understand.

116
Q

Suck Cost Fallacy

A

Not leaving a bad movie before it ends because you paid for it !!!

117
Q

Self serving bias

A

If we win it is our success, if we lose, it is someone else’s fault. (defence mechanism that protects a
person’s self-esteem)

118
Q

Consider both inside vs. outside view

A

Inside view is always optimistic.
Outside view often gives a less optimistic but more realistic view.
Example: When two companies merge: Inside view thinks things
are great, board members think this will increase stock prices.
Commonly when companies merge stock prices drop.

119
Q

Scientific Management - Frederick Taylor what did he wittness

A

The more productive you are, the fewer workers will be needed
2. Workers get paid for their time, so work at slowest acceptable pace
3. Workers have the freedom to create their own work procedure

120
Q

what are Fred Talyor’s 4 principles of scientific management

A

1.Use scientifically optimised work routines
2.Scientifically select and train workers
3.Ensure work routines are followed
4.Managers and workers to use scientific methods

121
Q

Differences between traditional & Lean (1

A

Traditional
* Decisions are made sequentially
by specialists and ‘thrown over
the wall’
* Activities are performed as soon
as possible
* Not all product life cycle stages
are considered in design

Lean
* Downstream players are
involved in upstream
decisions, and vice-versa
* Activities are performed at
the last responsible
moment
* All product life cycle stages
are considered in design

122
Q

What is the hawthorne effect

A

he alteration of behaviour by the subjects of a study due to their awareness of being observed

123
Q

what is cost variance

A

Difference (in dollars) between what was
earned in performing the task(s) and what it
actually costs to perform the task.
CV = Earned Value – Actual Cost
CV = BCWP – ACWP

124
Q

what does a negative schedule variance mean

A

behind schdule (EV - Pv)

125
Q

What does a negative CV mean

A

Over budget EV - AC

126
Q

what does a SPI lower than 1 mean

A

project is behind schdule = ev/pv

127
Q

what does a cpi lower than 1 mean

A

project is overbudget

128
Q

What are the components of SMARTER
