Characteristics of Project Cost Management
answer
The ability to influence cost is greatest at the early stages of the project, making early scope definition critical • Should consider the stakeholder requirements for capturing costs. Different stakeholders will measure project costs in different ways and at different times. • Is primarily concerned with the cost of the resources needed to complete project activities. • Should also consider the effect of project decisions on the subsequent recurring cost of using, maintaining, and supporting the product, service, or result of the project. For example, limiting the number of design reviews can reduce the cost of the project but could do so by increasing the customer's operating costs. • The cost management planning effort occurs early in project planning and sets the framework for each of the cost management processes so that performance of the processes will be efficient and coordinated.
question
Cost Management Plan
answer
Sets out the format and establishes the criteria for planning, structuring, estimating, budgeting, and controlling project costs
question
The cost management plan can establish
answer
• Level of accuracy • Units of measure • Organizational procedures links • Control thresholds • Rules of performance management • Reporting formats • Process descriptions
question
Level of Accuracy
answer
Activity cost estimates will adhere to a rounding of the data to a prescribed precision (e.g., $100, $1,000), based on the scope of the activities and magnitude of the project, and may include an amount for contingencies
question
Units of Measure
answer
Each unit used in measurements (such as staff hours, staff days, weeks, or lump sum) is defined for each of the resources
question
Organizational Procedures Links
answer
The work breakdown structure (WBS) provides the framework for the cost management plan, allowing for consistency with the estimates, budgets, and control of costs. The WBS component used for the project cost accounting is called the control account (CA). Each control account is assigned a unique code or account number(s) that links directly to the performing organization's accounting system.
question
Control Thresholds
answer
Variance thresholds for monitoring cost performance may be specified to indicate an agreed-upon amount of variation to be allowed before some action needs to be taken. Thresholds are typically expressed as percentage deviations from the baseline plan
question
Rules of Performance Measurement
answer
Earned value management (EVM) rules of performance measurement are set. For example, the cost management plan could: • Define the WBS and points at which measurement of control accounts will be performed, • Establish the earned value measurement techniques (e.g., weighted milestones, fixed formula, percent complete, etc.) to be employed, and • Specify the earned value management computation equations for determining the project estimate at completion (EAC) forecasts and other tracking methodologies
question
Reporting Formats
answer
The formats and frequency for the various cost reports are defined
question
Process Descriptions
answer
Descriptions of each of the three cost management processes are documented
question
Estimating Costs
answer
The process of developing an approximation of the monetary resources needed to complete project activities
question
Cost Estimates
answer
A prediction that is based on the information known at a given point in time. It includes the identification and consideration of costing alternatives to initiate and complete the project
question
Activity Cost Estimate
answer
A quantitative assessment of the likely costs for resources required to complete the activity
question
Characteristics of Cost Estimates
answer
• Are generally expressed in units of some currency (i.e., dollars, euro, yen, etc.), although in some instances other units of measure, such as staff hours or staff days, are used to facilitate comparisons by eliminating the effects of currency fluctuations • Sources of input information are derived from the outputs of project processes in other Knowledge Areas • Estimated for all resources that will be charged to the project. This includes, but is not limited to, labor, materials, equipment, services, and facilities, as well as special categories such as an inflation allowance or contingency costs • Can be presented in summary form or in detail. • Indirect costs, if they are included in the project estimate, can be included at the activity level or at higher levels
question
Accuracy of Cost Estimates
answer
Will increase as the project progresses through the project life cycle. Hence cost estimating is an iterative process from phase to phase

question
Examples of requirements with contractual and legal implications
answer
• Health • Safety • Security • Performance • Environmental • Insurance • Intellectual Property Rights • Licenses • Permits
question
Project Schedule Use in Estimate Costs
answer
The type and quantity of resources and the amount of time which those resources are applied to complete the work of the project are major factors in determining the project cost. Schedule activity resources and their respective durations are used as key inputs to this process
question
Estimate Activity Resources Impact on Estimate Costs
answer
Estimate Activity Resources involves determining the availability and quantities required of staff and material needed to perform schedule activities. It is closely coordinated with cost estimating
question
Estimate Activity Duration Impact on Estimate Costs
answer
Activity duration estimates will affect cost estimates on any project where the project budget includes an allowance for the cost of financing (including interest charges) and where resources are applied per unit of time for the duration of the activity. Activity duration estimates can also affect cost estimates that have time-sensitive costs included in them
question
Human Resource Plan Use in Estimate Costs
answer
Project staffing attributes, personnel rates, and related rewards/recognition are necessary components for developing the project cost estimates
question
Risk Register Use in Estimate Costs
answer
• Should be reviewed to consider risk mitigation costs • Risks, which can be either threats or opportunities, typically have an impact on both activity and overall project costs. • As a general rule, when the project experiences a negative risk event, the near-term cost of the project will usually increase, and there will sometimes be a delay in the project schedule
question
Estimate Costs: Enterprise Environmental Factors
answer
• Market Conditions. • Published commercial information.
question
Market Conditions Impact on Estimate Costs
answer
Describe what products, services, and results are available in the market, from whom, and under what terms and conditions. Regional and/or global supply and demand conditions greatly influence resource costs
question
Published Commercial Information Impact on Estimate Costs
answer
Resource cost rate information is often available from commercial databases that track skills and human resource costs, and provide standard costs for material and equipment. Published seller price lists are another source of information.
question

question
Expert Judgement Use in Estimate Costs
answer
• Cost estimates are influenced by numerous variables such as labor rates, material costs, inflation, risk factors, and other variables. • Provides valuable insight about the environment and information from prior similar projects. • Can also be used to determine whether to combine methods of estimating and how to reconcile differences between them
question
Analogous Estimating Use in Estimate Costs
answer
• Analogous cost estimating uses the values of parameters, such as scope, cost, budget, and duration or measures of scale such as size, weight, and complexity, from a previous, similar project as the basis for estimating the same parameter or measure for a current project. • When estimating costs, this technique relies on the actual cost of previous, similar projects as the basis for estimating the cost of the current project. • It is a gross value estimating approach, sometimes adjusted for known differences in project complexity. • Is frequently used to estimate a parameter when there is a limited amount of detailed information about the project, for example, in the early phases of a project. • Uses historical information and expert judgment. • Is generally less costly and time consuming than other techniques, but it is also generally less accurate. • Can be applied to a total project or to segments of a project, used in conjunction with other estimating methods. • Is most reliable when the previous projects are similar in fact and not just in appearance, and the project team members preparing the estimates have the needed expertise
question
Parametric Estimating Use in Estimate Costs
answer
• Use a statistical relationship between historical data and other variables (e.g., square footage in construction) to calculate an estimate for activity parameters, such as cost, budget, and duration. • This technique can produce higher levels of accuracy depending upon the sophistication and underlying data built into the model. • Can be applied to a total project or to segments of a project, in conjunction with other estimating methods.
question
Bottom-up Estimating Use in Estimate Costs
answer
• Is a method of estimating a component of work • The cost of individual work packages or activities is estimated with the greatest level of specified detail. • The detailed cost is then summarized or "rolled up" to higher levels for subsequent reporting and tracking purposes. • The cost and accuracy of bottom-up cost estimating is typically influenced by the size and complexity of the individual activity or work package
question
Three-Point Estimates Use in Estimate Costs
answer
• The accuracy of single-point activity cost estimates can be improved by considering estimation uncertainty and risk. • Cost estimates based on this equation (or even on a simple average of the three points) may provide more accuracy, and the three points clarify the range of uncertainty of the cost estimates
question
Reserve Analysis Use in Estimate Costs
answer
• Cost estimates may include contingency reserves (sometimes called contingency allowances) to account for cost uncertainty. • The contingency reserve may be a percentage of the estimated cost, a fixed number, or may be developed by using quantitative analysis methods. • As more precise information about the project becomes available, the contingency reserve may be used, reduced or eliminated. • Contingency should be clearly identified in cost documentation. • Contingency reserves are part of the funding requirements
question
Cost of Quality (COQ) Use in Estimate Costs
answer
Assumptions about costs of quality may be used to prepare the activity cost estimate
question
Project Management Estimating Software Use in Estimate Costs
answer
• Project management cost estimating software applications, computerized spreadsheets, simulation, and statistical tools are becoming more widely accepted to assist with cost estimating. • Such tools can simplify the use of some cost estimating techniques and thereby facilitate rapid consideration of cost estimate alternatives
question
Vendor Bid Analysis
answer
Cost estimating methods may include analysis of what the project should cost, based on the responsive bids from qualified vendors. Where projects are awarded to a vendor under competitive processes, additional cost estimating work can be required of the project team to examine the price of individual deliverables and to derive a cost that supports the final total project cost
question
Outputs of Estimate Costs
answer
1. Activity Cost Estimates 2. Basis of Estimates 3. Project Document Updates
question
Basis of Estimates
answer
The supporting documentation should provide a clear and complete understanding of how the cost estimate was derived. Supporting detail for activity cost estimates may include: • Documentation of the basis of the estimate (i.e., how it was developed), • Documentation of all assumptions made, • Documentation of any known constraints, • Indication of the range of possible estimates (e.g., $10,000 (±10%) to indicate that the item is expected to cost between a range of values), and • Indication of the confidence level of the final estimate

answer
• The project manager may be required to obtain approval before obligating or spending management reserve. • Are not a part of the project cost baseline, but may be included in the total budget for the project. • They are not included as a part of the earned value measurement calculations
question
Determine Budget: Expert Judgement Sources
answer
Judgment provided based upon expertise in an application area, Knowledge Area, discipline, industry, etc., as appropriate for the activity being performed should be used in determining the budget. Expert judgment is available from many sources, including, but not limited to: • Other units within the performing organization, • Consultants, • Stakeholders, including customers, • Professional and technical associations, and • Industry groups
question
Determine Budget: Historical Relationships
answer
• Any historical relationships that result in parametric estimates or analogous estimates involve the use of project characteristics (parameters) to develop mathematical models to predict total project costs. • Such models can be simple (e.g., residential home construction is based on a certain cost per square foot of space) or complex (e.g., one model of software development costing uses multiple separate adjustment factors, each of which has numerous points within it)
question
Cost and accuracy of parametric models are more reliable when
answer
• Historical information used to develop the model is accurate, • Parameters used in the model are readily quantifi able, and • Models are scalable, such that they work for a large project, a small project, and phases of a project
question
Determine Budget: Funding Limit Reconciliation
answer
• The expenditure of funds should be reconciled with any funding limits on the commitment of funds for the project. • A variance between the funding limits and the planned expenditures will sometimes necessitate the rescheduling of work to level out the rate of expenditures. • This can be accomplished by placing imposed date constraints for work into the project schedule
question
Determine Budget: Cost Performance Baseline
answer
• an authorized time-phased budget at completion (BAC) used to measure, monitor, and control overall cost performance on the project. • It is developed as a summation of the approved budgets by time period and is typically displayed in the form of an S-curve • In the earned value management technique the cost performance baseline is referred to as the performance measurement baseline (PMB)
question
Determine Budget: Project Funding Requirements
answer
• Total funding requirements and periodic funding requirements (e.g., quarterly, annually) are derived from the cost baseline. • The cost baseline will include projected expenditures plus anticipated liabilities. • Funding often occurs in incremental amounts that are not continuous, which appear as steps • The total funds required are those included in the cost baseline, plus management reserves, if any
question
Determine Budget: Project Document Updates
answer
• Risk register, • Cost estimates, and • Project schedule
question
Control Costs
answer
The process of monitoring the status of the project to update the project budget and managing changes to the cost baseline
question
Characteristics of Control Costs
answer
• Updating the budget involves recording actual costs spent to date. • Any increase to the authorized budget can only be approved through the Perform Integrated Change Control process • Monitoring the expenditure of funds without regard to the value of work being accomplished for such expenditures has little value to the project other than to allow the project team to stay within the authorized funding. • Thus much of the effort of cost control involves analyzing the relationship between the consumption of project funds to the physical work being accomplished for such expenditures.
question
The key effective cost control
answer
Is the management of the approved cost performance baseline and the changes to that baseline
question
Project cost control includes
answer
• Influencing the factors that create changes to the authorized cost baseline, • Ensuring that all change requests are acted on in a timely manner, • Managing the actual changes when and as they occur, • Ensuring that cost expenditures do not exceed the authorized funding, by period and in total for the project, • Monitoring cost performance to isolate and understand variances from the approved cost baseline, • Monitoring work performance against funds expended • Preventing unapproved changes from being included in the reported cost or resource usage, • Informing appropriate stakeholders of all approved changes and associated cost, and • Acting to bring expected cost overruns within acceptable limits

question
CPI < 1
answer
Indicates a cost overrun for work completed
question
CPI > 1
answer
Indicates a cost underrun of performance to date
question
Forecasting
answer
• As the project progresses, the project team can develop a forecast for the estimate at completion(EAC) that may differ from the budget at completion (BAC) based on the project performance. • If it becomes obvious that the BAC is no longer viable, the project manager should develop a forecasted EAC. • Forecasting the EAC involves making estimates or predictions of conditions and events in the project's future based on information and knowledge available at the time of the forecast. • Forecasts are generated, updated, and reissued based on work performance information provided as the project is executed. • The work performance information covers the project's past performance and any information that could impact the project in the future. • EACs are typically based on the actual costs incurred for work completed, plus an estimate to complete (ETC) the remaining work. • It is incumbent on the project team to predict what it may encounter to perform the ETC, based on its experience to date. • The EVM method works well in conjunction with manual forecasts of the required EAC costs.
question
Most common EAC forecasting approach
answer
a manual, bottom-up summation by the project manager and project team
question
Bottum Up EAC Method
answer
• method builds upon the actual costs and experience incurred for the work completed, and requires a new estimate to complete the remaining project work. • This method may be problematic in that it interferes with the conduct of project work. • The personnel who are performing the project work have to stop working to provide a detailed bottom-up ETC of the remaining work. • Typically there is no separate budget to perform the ETC, so additional costs are incurred for the project to conduct the ETC • The project manager's manual EAC can be quickly compared with a range of calculated EACs representing various risk scenarios.
question
Three most common methods for EAC forecast of ETC
answer
• Work performed at the budgeted rate • Work performed at the present CPI • Work considering both SPI and CPI factors Each of these approaches can be correct for any given project and will provide the project management team with an "early warning" signal if the EAC forecasts are not within acceptable tolerances
question
EAC forecast for ETC (work performed at the budgeted rate)
answer
• This EAC method accepts the actual project performance to date (whether favorable or unfavorable) as represented by the actual costs, and predicts that all future ETC work will be accomplished at the budgeted rate. • When actual performance is unfavorable, the assumption that future performance will improve should be accepted only when supported by project risk analysis.
question
EAC forecast for ETC (work performed at the present CPI)
answer
• This method assumes what the project has experienced to date can be expected to continue in the future. • The ETC work is assumed to be performed at the same cumulative cost performance index (CPI) as that incurred by the project to date.
question
EAC forecast for ETC (considering both SPI and CPI factors)
answer
• In this forecast, the ETC work will be performed at an efficiency rate that considers both the cost and schedule performance indices. • It assumes both a negative cost performance to date, and a requirement to meet a firm schedule commitment by the project. • This method is most useful when the project schedule is a factor impacting the ETC effort. • Variations of this method weigh the CPI and SPI at different values (e.g., 80/20, 50/50, or some other ratio) according to the project manager's judgment.
question
EAC forecast for ETC (work performed at the budgeted rate): Equation
answer
EAC = AC + BAC - EV
question
EAC forecast for ETC (work performed at the present CPI): Equation
answer
EAC = BAC / cumulative CPI
question
EAC forecast for ETC (considering both SPI and CPI factors): Equation
answer
AC + [(BAC - EV) / (cumulative CPIx cumulative SPI)]
question
TCPI
answer
To Complete Performance Index
question
To Complete Performance Index
answer
Is the calculated projection of cost performance that must be achieved on the remaining work to meet a specified management goal, such as the BAC or the EAC
question
TCPI Based on BAC
answer
• If it becomes obvious that the BAC is no longer viable, the project manager develops a forecasted estimate at completion (EAC). • Once approved, the EAC effectively supersedes the BAC as the cost performance goal.
question
TCPI Based on BAC: Equation
answer
(BAC - EV) / (BAC - AC)
question
TCPI Based on EAC
answer
• If the cumulative CPI falls below the baseline plan, all future work of the project will need to immediately be performed in the range of the TCPI (BAC) to stay within the authorized BAC. • Whether this level of performance is achievable is a judgment call based on a number of considerations, including risks, schedule, and technical performance. • Once management acknowledges that the BAC is no longer attainable, the project manager will prepare a new estimate at completion (EAC) for the work, and once approved, the project will work to the new EAC value. • This level of performance is displayed as the TCPI (EAC)
question
TCPI Based on EAC: Equation
answer
(BAC - EV) / (EAC - AC)
question
Performance Reviews
answer
Compare cost performance over time, schedule activities or work packages overrunning and under running the budget, and estimated funds needed to complete work in progress
question
Performance Review Information when using EVM
answer
• Variance analysis • Trend analysis • Earned value performance
question
Performance Review: Variance Analysis
answer
As used in EVM compares actual project performance to planned or expected performance. Cost and schedule variances are the most frequently analyzed
question
Performance Review: Trend Analysis
answer
Examines project performance over time to determine if performance is improving or deteriorating. Graphical analysis techniques are valuable for understanding performance to date and for comparison to future performance goals in the form of BAC versus EAC and completion dates
question
Performance Review: Earned Value Performance
answer
Earned value management compares the baseline plan to actual schedule and cost performance
question
Variance Analysis Use in Control Cost
answer
• Cost performance measurements (CV, CPI) are used to assess the magnitude of variation to the original cost baseline. • Important aspects of project cost control include determining the cause and degree of variance relative to the cost performance baseline and deciding whether corrective or preventive action is required. •The percentage range of acceptable variances will tend to decrease as more work is accomplished. • The larger percentage variances allowed at the start of the project can decrease as the project nears completion
question
Project Management Software Use in Control Costs
answer
Used to monitor the three EVM dimensions (PV, EV, and AC), to display graphical trends, and to forecast a range of possible final project results
question
Control Costs: Work Performance Measurements
answer
The calculated CV, SV, CPI, and SPI values for WBS components, in particular the work packages and control accounts, are documented and communicated to stakeholders
question
Control Costs: Budget Forecasts
answer

question
Control Costs: Organizational Process Assets Updates
answer
• Causes of variances, • Corrective action chosen and the reasons, and • Other types of lessons learned from project cost control
question
Control Costs: Change Requests
answer
• Analysis of project performance can result in a change request to the cost performance baseline or other components of the project management plan. • Change requests can include preventive or corrective actions and are processed for review and disposition through the Perform Integrated Change Control process
question
Control Costs: Project Management Plan Updates
answer
• Cost performance baseline. Changes to the cost performance baseline are incorporated in response to approved changes in scope, activity resources, or cost estimates. In some cases, cost variances can be so severe that a revised cost baseline is needed to provide a realistic basis for performance measurement. • Cost management plan
question
Control Costs: Project Document Updates
answer
• Cost estimates • Basis of estimates

question
In the earned value management technique, the cost performance baseline is referred to as
answer
the performance measurement baseline (PMB)
question
Project Selection Criterion with NPV
answer
Select the project with the largest value, regardless of the project duration or payback period, as time value as already been taken into account
question
Payback Period
answer
Number of years required for an organization to recapture an initial investment. Discount period is not taken into account in calculations for payback period
question
Selection Criterion with Payback Period
answer
Select a project with a lower payback period
question
Crashing of a project results in
answer
decreased duration and increased costs. This is reflected with CPI is less than 1 and SPI is greater than 1
question
Project Selection is performed in the
answer
initiating phase. Any project selection methods are no longer valid once the project is in any of the subsequent process groups
question
Recommendation when CPI > 1 and SPI < 1
answer
Since SPI is less than 1, this means that project is behind schedule; hence it is recommended to crash the project to bring it on schedule. Please note that crashing may increase costs. Since your project has CPI greater than 1, cost will not be a concern
question
BCR
answer
Benefit Cost Ratio
question
Benefit Cost Ratio: Equation
answer
Benefits (or Payback or Revenue) / Costs
question
BCR > 1
answer
means that benefits (i.e. expected revenue) is greater than the cost. Hence it is beneficial to do the project
question
BCR < 1
answer
means that benefits (i.e. expected revenue) is less than the cost. Hence it is not beneficial to do the project
question
Project Selection Criterion with BCR
answer
Select the project with the greater BCR
question
0-100 Rule
answer
whereby a task is considered to be either 0 percent complete or 100 percent complete, but nothing in between
question
Opportunity Cost is not...
answer
a project selection criteria
question
Life Cycle Costs
answer
• include the cost of operations, which is beyond the scope of the project • Includes direct and indirect costs • Includes periodic or continuing cost of operations and maintenance • life cycle costs are not the responsibility of the project manager
question
Project Selection: Life Cycle Costs
answer
• For two projects having the same investment, select a project with lower life cycle costs • Even if one project has a lower NPV, it may be selected if it has a lower life cycle cost
