Expand Earned Value Management (EVM) and introduce the concept of Earned Progress (ES)
Tailoring considerations
knowledge management. Does the organization have an easy-to-use, formal knowledge management system and financial database that project managers are required to use?
Estimates and budgets. Does the organization have formal or informal policies, procedures and guidelines related to cost estimating and budgeting?
Earned value management. Does the organization use earned value management to manage projects?
Use of agile methods.
Does the organization use agile methods to manage projects? What impact does this have on cost estimates?
Governance. Does the organization have formal or informal audit and governance policies, procedures and guidelines?
Agile factors to consider
For projects with high variability, incomplete scope, and frequent changes, lightweight estimation methods can be used to quickly generate high-level forecasts of project labor costs, and the forecasts can be easily adjusted when changes occur.

Project Charter
Specifies pre-approved financial resources from which detailed project costs can be determined.
The project approval requirements stipulated in the project charter also have an impact on project cost management.
project management plan
◆Progress management plan
Established criteria and activities for preparing, monitoring and controlling project progress
It also provides processes and control methods that affect cost estimation and management.
◆Risk management plan
Provides ways to identify, analyze and monitor risks
It also provides processes and control methods that affect cost estimation and management.
business environment factors
◆ Organizational culture and structure that can affect cost management;
◆ Market conditions, which determine what products, services and results are available in local and global markets;
◆ Currency exchange rate, used to convert project costs incurred in multiple countries;
◆ Published business information can often obtain resource cost rates and related information from business databases, and these databases dynamically track the cost data of human resources with corresponding skills, and also provide standard cost data of materials and equipment. Relevant information can also be obtained from the price list published by the seller;
◆ Project management information system can provide a variety of solutions for managing costs;
◆ Differences in productivity between different regions may have a huge impact on project costs.

cost management plan
The cost management plan is a component of the project management plan that describes how project costs will be planned, scheduled, and controlled. The cost management process and its tools and techniques should be documented in the cost management plan.
unit of measurement.
The unit of measurement for each resource needs to be specified, such as person-hours, person-days, or weeks to measure time, meters, liters, tons, kilometers, or cubic yards to measure quantity, or a total price expressed in currency.
Accuracy.
Depending on the scope of activities and project size, set how much to round up or down the cost estimate (for example, $995.59 is rounded up to $1,000).
Accuracy.
Specify an acceptable range (such as ±10%) for activity cost estimates, which may include a certain amount of contingency reserves.
Organization program link.
The work breakdown structure (see Section 5.4) provides a framework for the cost management plan so that cost estimation, budgeting and control can be carried out in a standardized manner. The components of the WBS used in project costing are called control accounts (CA), each control account has a unique code or account number that is directly linked to the accounting system of the performing organization.
Control critical value.
Deviation thresholds may need to be specified for monitoring cost performance. It is the maximum variance allowed before some action is required, usually expressed as a percentage deviation from the baseline plan.
Performance Measurement Rules.
Earned value management (EVM) rules for performance measurement need to be specified. For example, a cost management plan should:
■ Define control accounts in the WBS for performance measurement;
■ Determine the EVM technique to be used (such as weighted milestone method, fixed formula method, percentage of completion method, etc.);
■ Specify the tracking method and the EVM formula used to calculate the project's estimate at completion (EAC), which can be used to validate the estimate of completion derived from a bottom-up approach.
report format.
The format and frequency of preparation of various cost reports need to be specified.
Other details. including but not limited to):
■ Description of strategic funding options;
■ Procedures for dealing with exchange rate fluctuations;
■ Procedures for recording project costs.
2. Estimated costs
Overview
Estimating costs is the process of making an approximate estimate of the cost of resources required to complete project work.
The main purpose of this process is to determine the funding required for the project.
Estimated costs are cost predictions based on known information at a specific point in time.
When estimating costs, you need to identify and analyze alternative cost options that can be used to start and complete the project; you need to weigh alternative cost options and consider risks, such as comparing homemade costs with outsourced costs, purchase costs with leasing costs, and the sharing of multiple resources. programs to optimize project costs.
cost estimate unit
Cost estimates are usually made in a certain currency unit (such as US dollars, euros, yen, etc.)
However, other units of measurement, such as person-hours or person-days, can sometimes be used to eliminate the effects of inflation and facilitate cost comparisons.
During the project life cycle, the accuracy of project estimates will gradually improve as the project progresses.
For example, a rough order of Magnitude (ROM) estimate of the project can be derived during the initiation phase, ranging from −25% to 75%;
Later, as the information becomes more detailed, the range of deterministic estimates can be narrowed to −5% to 10%.
Some organizations have developed guidelines for when to perform optimizations and the level of confidence or accuracy to achieve with each optimization.
Cost estimates should take into account all resources that will be charged to the project, including (but not limited to) labor, materials, equipment, services, facilities, as well as special cost categories such as inflation allowances, financing costs, or contingency costs.

Resource cost rates and related information can often be obtained from commercial databases, which dynamically track cost data for human resources with corresponding skills and also provide standard cost data for materials and equipment. Relevant information can also be obtained from the seller's published price list.
Exchange rates and inflation rates.
For large-scale projects spanning multiple years and involving multiple currencies, exchange rate fluctuations and inflation need to be understood and factored into the estimating cost process.

Tools & Techniques
expert judgment
See section 4.1.2.1. Input should be sought from an individual or group with expertise or training in:
◆ Similar projects in the past;
◆ Information from industries, disciplines and application areas;
◆ Cost estimation methods.
analogy estimation
See Section 6.4.2.2. Cost analogies are estimated using parameter values or attributes from similar past projects.
Low cost and less time consuming. Used in the startup phase when detailed information is insufficient and results need to be obtained quickly.
parameter estimation
See section 6.4.2.3. Parametric estimating refers to the use of statistical relationships between historical data and other variables, such as square footage in building construction, to estimate the cost of project work
The accuracy of parameter estimation depends on the maturity of the parameter model and the reliability of the underlying data.
Parametric estimating can be for the entire project or a portion of the project, and can be used in conjunction with other estimating methods.
Bottom-up estimation
Estimated individuals are aggregated layer by layer
The accuracy of a bottom-up estimate, and the cost itself, often depends on the size or other attributes of the individual activity or work package.
three point estimate
See Section 6.4.2.4. The accuracy of single-point cost estimates can be improved by taking into account the uncertainty and risk in the estimate and using three estimates to define an approximate range of activity costs: ◆ Most likely cost (c M). The cost of an activity resulting from a more realistic estimate of the work required and associated costs. ◆The most optimistic cost (c O). The cost based on the best case scenario for the activity. ◆ The most pessimistic cost ( c P ). Cost based on the worst-case scenario for the activity. The expected cost (c E ) is calculated using the formula based on the assumed distribution of activity costs over three estimate intervals. Two commonly used formulas are triangular distribution and beta distribution, and their calculation formulas are: ◆Triangular distribution. c E = (c O c M c P ) / 3 ◆ Beta distribution. c E = (c O 4c M c P ) / 6 Calculate the expected cost based on an assumed distribution of three points and describe the uncertainty interval for the expected cost.
data analysis
Alternatives analysis.
Alternatives analysis is a technique for evaluating identified alternatives to decide which option to choose or which method to use to perform project work. For example, evaluate the impact of buying and manufacturing deliverables on cost, schedule, resources, and quality respectively.
Reserve analysis.
A contingency reserve is a portion of the budget that is included in the cost baseline to address identified risks; the contingency reserve is often thought of as that portion of the budget that addresses “known-unknown” risks that affect the project. Project managers have access to
For example, you can predict that some project deliverables will need to be reworked, but you don’t know how much work the rework will entail. A contingency reserve can be set aside to cover these unknown amounts of rework. From a specific activity to an entire project, any level can have its contingency reserve.
The contingency reserve can be a percentage of the cost estimate, a fixed value, or determined through quantitative analysis.
As project information becomes clearer, contingency reserves can be drawn down, reduced, or eliminated. Contingency reserves should be clearly listed in cost documents.
The contingency reserve is part of the cost baseline and is part of the project's overall funding requirements.
quality cost.
When estimating, various assumptions about quality costs (see Section 8.1.2.3) may be used. This includes an assessment of:
Whether to increase investment to meet the requirements or bear the costs caused by not meeting the requirements;
Whether to seek short-term cost reduction, or bear the consequences of frequent problems later in the product life cycle.
Project Management Information System (PMIS)
Project management information systems can include spreadsheets, simulation software, and statistical analysis tools that can be used to assist in cost estimating. These tools simplify the use of certain cost estimating techniques and allow multiple cost estimating options to be quickly considered.
decision making
vote
Voting is the process of evaluating multiple future courses of action to achieve a desired outcome. These techniques can engage team members, improve the accuracy of estimates, and increase accountability for estimate results.
output
Cost Estimate
The cost estimate includes a quantitative estimate of the likely costs to complete the project work, contingency reserves to deal with identified risks, and management reserves to deal with unplanned work.
Cost estimates can be summarized or detailed.
The cost estimate should cover all resources used by the project, including (but not limited to) direct labor, materials, equipment, services, facilities, information technology, as well as some special cost categories, such as financing costs (including interest), inflation allowances, Exchange rate or cost contingency reserves. Indirect costs can be charged at the activity level or higher if they are also included in the project estimate.
Estimate basis
The amount and type of supporting information required for a cost estimate will vary by application area, and regardless of its level of detail, supporting documentation should clearly and completely describe how the cost estimate was derived.
◆ Documentation on the basis for the estimate (e.g., how the estimate was prepared);
◆ Documentation of all assumptions;
◆ Documentation on known constraints;
◆ Documentation on identified risks that should be considered when estimating costs;
◆ Description of the estimate range (for example, “$10,000 ±10%” explains the range of expected costs);
◆ A description of the confidence level in the final estimate.
Project file updates
Assumption log.
See section 4.1.3.2. During the cost estimating process, new assumptions may be made, new constraints may be identified, or existing assumptions or constraints may be re-examined and modified. The hypothesis log should be updated accordingly with this new information.

3. Make a budget
Overview
Budgeting is the process of summarizing the estimated costs of all individual activities or work packages to establish an approved cost baseline.
The main purpose of this process is to establish a cost baseline against which project performance can be monitored and controlled.
The project budget includes all funds approved for execution of the project,
The cost baseline is the approved project budget allocated by time period and includes contingency reserves but does not include management reserves.

data analysis
Data analysis techniques that can be used in the budgeting process include (but are not limited to) reserve analysis that can establish project management reserves. Management reserve is a project budget specifically set aside for management control purposes to deal with unforeseen work within the project scope. It is intended to deal with "unknown-to-unknown" risks that will affect the project. Management reserves are not included in the cost baseline but are part of the overall project budget and funding requirements. When management reserves are used to fund unforeseen work, the used management reserves are added to the cost baseline, resulting in a change in the cost baseline.

Management reserve is a project budget specifically set aside for management control purposes to deal with unforeseen work within the project scope. It is intended to deal with "unknown-to-unknown" risks that will affect the project.
Management reserves are not included in the cost baseline but are part of the overall project budget and funding requirements.
When management reserves are used to fund unforeseen work, the used management reserves are added to the cost baseline, resulting in a change in the cost baseline.
Historical information review
Reviewing historical information can help with parameter or analog estimation.
Historical information can include various project characteristics (parameters) that are used to build mathematical models that predict the total project cost. These mathematical models can be simple (for example, the total cost of building a house depends on the construction cost per unit area) or complex (for example, the cost model of a software development project has multiple variables, each of which is affected by many factors). Analog and parametric models can vary widely in cost and accuracy. They will be most reliable when:
◆ The historical information used to build the model is accurate;
◆ Parameters in the model are easy to quantify;
◆ The model can be adjusted so that it is applicable to large projects, small projects and various project stages.
Funding limit balance
Ensuring adequate funding for each phase, component, and overall project within established funding constraints, which may result in changes to the schedule
If a discrepancy between funding constraints and planned expenditures is discovered, the schedule of the work may need to be adjusted to balance the level of funding expenditures.
This can be accomplished by adding mandatory dates to the project schedule.
Coping with Stage Fund Investment Restrictions
Financing
Financing refers to obtaining funds for a project. Long-term infrastructure, industrial and public services projects often seek external financing. If a project uses external funding, the funding entity may impose certain requirements that must be met.

4. Control costs
Overview
Controlling costs is the process of monitoring project status to update project costs and manage changes to the cost baseline.
The main function is to maintain the cost baseline throughout the project.
The analysis should focus on the relationship between the expenditure of project funds and the corresponding work completed.
The key to effective cost control is managing an approved cost baseline. Project cost control includes:
◆ Influence factors that cause cost basis changes;
◆ Ensure all change requests are processed promptly;
◆ Manage changes when they actually occur;
◆ Ensure that cost expenditures do not exceed the approved funding limit, neither exceeding the limits allocated by time period, by WBS component, by activity, nor exceeding the overall project limit;
◆ Monitor cost performance and identify and analyze deviations from cost baselines;
◆ Supervise work performance against fund expenditure;
◆ Prevent unapproved changes in cost or resource usage reports;
◆ Report all approved changes and their associated costs to relevant parties;
◆ Try to keep expected cost overruns within acceptable limits.

data analysis
◆ Earned value analysis (EVA).
Earned value analysis compares actual schedule and cost performance to a performance measurement baseline. EVM integrates scope baseline, cost baseline and schedule baseline to form a performance measurement baseline. For each work package and control account, it calculates and monitors the following three key indicators:
budget at completion BAC
Budget At Completion
The budgeted value of all planned work is the cost baseline (earned value analysis, contingency reserves are not included in the calculation)
BAC = total PV at completion
The project is completed when EV=BAC
Planned value PV
plan value
The budgeted value of work planned to be completed by a certain point in time.
PV=planned workload
Also called BCWS
Earned value EV
Earned Value
The budgeted value of work actually completed as of a certain point in time
EV=actual workload
Also called BCWP
Actual cost AC
actual cost
How much money has actually been spent up to a certain point in time?
AC = actual workload x actual unit price
Also called ACWP
Deviation analysis
Variance analysis is used to explain the causes, effects and corrective measures of cost variance (CV = EV — AC), schedule variance (SV = EV — PV) and completion variance (VAC = BAC — EAC). (The bigger the better)
Schedule Variance (SV) Schedule Variance
Expressed as the difference between earned value and planned value. It refers to how far ahead or behind a project is at a given point in time.
Formula: SV = EV — PV.
Cost Variance (CV) Cost Variance
Expressed as the difference between earned value and actual cost, it is the budget deficit or surplus at a given point in time.
Formula: CV = EV — AC.
Schedule Performance Index (SPI) Schedule Performance Index
It is an indicator for measuring schedule efficiency, expressed as the ratio of earned value to planned value, and reflects the efficiency of the project team in completing the work. When SPI is less than 1.0, it means that the amount of work completed does not meet the planned requirements; when SPI is greater than 1.0, it means that the amount of work completed exceeds the plan.
Because the SPI measures the total effort on the project, a separate analysis of performance on the critical path is also required to confirm whether the project will be completed earlier or later than the planned completion date.
SPI is equal to the ratio of EV to PV. Formula: SPI = EV/PV.
Cost Performance Index (CPI) Cost Performance Index
A measure of the cost efficiency of budgeted resources, expressed as the ratio of earned value to actual costs. It is the most critical EVA metric and measures the cost efficiency of work completed. When the CPI is less than 1.0, it means there is a cost overrun for the work done; when the CPI is greater than 1.0, it means there is a cost surplus so far.
CPI is equal to the ratio of EV to AC. Formula: CPI = EV/AC.
Deviations from the original cost baseline can be evaluated through cost performance measurements.
Identify differences between cost baseline and actual project performance by comparing planned costs to actual costs
trend analysis. See section 4.5.2.2.
Trend analysis is designed to examine changes in project performance over time to determine whether performance is improving or deteriorating.
chart
In earned value analysis, the three parameters of planned value, earned value and actual cost can be monitored and reported either in stages (usually on a weekly or monthly basis) or on a cumulative basis. Figure 7-12 shows the EV data as an S-curve for a project that is over budget and behind schedule.
predict
As the project progresses, the project team can forecast the Estimate at Completion (EAC) based on project performance, and the forecast results may differ from the Budget at Completion (BAC). If it is apparent that the BAC is no longer feasible, the project manager should consider forecasting the EAC. Forecasting EAC is to predict future project situations and events based on currently available performance information and other knowledge.
ETC Estimate To Complete
The estimated expected cost of the remaining work up to a certain point in time (how much more work is estimated to cost for the remaining work)
EAC Estimate at Completion
Estimated total expected cost of project completion as of a certain point in time
AC actual cost AC actual cost
How much money has actually been spent up to a certain point in time?
BAC Budget At Completion
The budgeted value of all planned work is the cost baseline (earned value analysis, contingency reserves are not included in the calculation)
EAC=ETC AC
Estimate at completion = Estimate to be completed Actual cost
AC is the raw performance data, which is the measured value
ETC needs to be calculated
EAC Estimate at Completion
EAC=AC (BAC-EV)
Atypical, remaining work continues according to planned performance
EAC=AC (BAC-EV)/CPI=BAC/CPI
Typically, remaining work continues at the current cost performance index
EAC=AC (BAC-EV)/(CPI*SPI)
The remaining work will also be affected by CPI and SPI.
Key index CR=CPI*SPI
EAC=AC bottom-up reestimated ETC
The scheduled plan is no longer valid
memory method
BAC-EV=budgeted value of remaining work
EAC=AC (budgeted value of remaining work/remaining work performance)
If calculating the progress completion estimate, the relevant parameters should be converted into time units. However, CPI and SPI cannot use time units and can only use monetary units.
Reserve analysis
In the process of cost control, reserve analysis can be used to monitor the use of contingency reserves and management reserves in the project to determine whether these reserves are still needed, or whether additional reserves need to be added. As project work progresses, these reserves may have been planned to cover the costs of risks or other contingencies; conversely, if opportunities for cost savings are seized, the savings may be added to the contingency reserve or as earnings ( Profit) is divested from the project.
If the identified risks do not materialize, unused contingency reserves may have to be deducted from the project budget, freeing resources for other projects or operations. At the same time, further risk analysis within the project may reveal the need to request additional reserves for the project budget.
To complete Performance Index (TCPI) To complete Performance Index
The To-Complete Performance Index (TCPI) is a cost performance indicator that the use of remaining resources must achieve in order to achieve specific management goals. It is the remaining work cost/remaining budget.
TCPI refers to the cost performance indicator that the implementation of the remaining work must achieve in order to achieve specific management goals (such as BAC or EAC). If the BAC (budget at completion) is no longer feasible, the project manager should consider using a forecasted EAC (estimate at completion). Once approved, the BAC is replaced with the EAC.
TCPI formula based on BAC: TCPI = (BAC — EV) / (BAC — AC).
If BAC is no longer feasible, the TCPI formula based on EAC: TCPI = (BAC — EV) / (EAC — AC).
Formula memory method: CPI=EV/AC, TCPI=(BAC-EV)/(BAC-AC)
Completion deviation VAC=BAC-EAC
TCPI<1
The remaining work is less than the money and can be easily completed
TCPI=1
The remaining work is the same as the money, just finished
TCPI>1
There's more work left than money, so it's not easy to finish.
Project Management Information System (PMIS)
Project management information systems are often used to monitor the three EVM indicators of PV, EV, and AC, draw trend charts, and predict the likely range of final project results.

job performance information
See section 4.5.1.3. Work performance information includes information about the performance of project work (against a cost baseline), allowing the assessment of deviations in work performed and work costs at both the work package level and the control account level. For projects using earned value analysis, CV, CPI, EAC, VAC, and TCPI will be recorded in the work performance report (see Section 4.5.3.1).
cost forecast
Whether it is a calculated EAC value or a bottom-up estimated EAC value, it needs to be recorded and communicated to relevant parties.
change request
See section 4.3.3.4. After analyzing project performance, change requests may be made to the cost and schedule baselines, or other components of the project management plan. Change requests should be reviewed and processed through the implementation of the overall change control process (see Section 4.6).
