4- Project Cost Management

Project Cost Management

Unit 7

Project cost management• Project cost management includes the processes involved in estimating,

budgeting, and controlling costs so that the project can be completed within the approved budget

• It is primarily concerned with the cost of the resources needed to complete schedule activities

• Should consider the information needs of the project stakeholders

• With proper planning, you can:

• Adjust the project plan to conform to the budget

• Track and manage cost once the project execution begins

• Compare actual cost to the original planned cost and analyze any variances between the two

Cost Management Plan• The planning effort of the processes of the Cost

Management Plan is a part of the develop project management plan

( Cost management plan can establish the following )• Precision level - The prescribed precision for rounding data related to schedule

activity cost estimates

• Units of measure - Define units of measurement for each of the resources

• Organizational procedure links - The WBS component used for the project cost accounting is called a control account (CA); each CA is assigned a code or account number

• Control thresholds - Variance thresholds for cost at designated time points in the project to indicate the agreed to amount allowable variance

4

• The planning effort of the processes of the Cost Management Plan is a part of the develop project management plan

( Cost management plan can establish the following )• Reporting formats - The format for various cost reports

• Process descriptions - Descriptions of each of the three cost management processes

7.1 Estimate Costs

The process of developing an approximation (estimate) of the cost of the resources needed to complete each schedule activity

•Estimator must consider the possible causes of variation of cost estimates, including risks

•Includes identifying and considering various costing alternatives

•Costs for schedule activities are estimated for all resources that will be charged to the project

7

Scope Baseline

Project ScheduleThe 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.

• Determine Budget is the process of aggregating the estimated costs of individual activities or work packages to establish an authorized cost baseline.

• This baseline includes all authorized budgets, but excludes management reserves.

• Project budgets constitute the funds authorized to execute the project.

• Project cost performance will be measured against the authorized budget.

15

Cost Aggregation (Tool)

•Schedule activity cost estimates are aggregated by work packages in accordance with the WBS

•Work package cost estimates are then aggregated for the higher component levels of the WBS, such as the control account, and ultimately for the entire project

Funding Limit Reconciliation (Tool)•The expenditure of funds should be reconciled with any funding limits on the commitment of funds for the project.

Cost Performance Baseline (Output)•The cost performance baseline is 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

Project Funding Requirements (Output)•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

7.3 Control Costs

Control Costs is the process of monitoring the status of the project to update the project budget and managing changes to the cost baseline.

Project cost control includes:

•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 work performance against funds expended,

Earned Value Management Analysis

Earned value technique (EVT)

Compares the cumulative value of the budgeted cost of work Earned to both

1. The budgeted cost of work scheduled (planned)

2. The actual cost or work performed (actual)

An important part of Cost Control is to determine the cause of a variance, the magnitude of the variance, and to decide if the variance requires corrective action

EVT uses the Cost Baseline contained in the project management plan to assess project progress and the magnitude of any variations that occur

28

• Earned Value. (EV) Value of work performed expressed in terms of the approved budget

• Planned Value. (PV) Authorized budget assigned to the work to be accomplished for an activity or work breakdown structure component.

• Actual Cost. (AC) Total cost actually incurred and recorded in accomplishing work performed for an activity or work breakdown structure component.

• Schedule Variance (SV) is a measure of schedule performance on a project.

SV = ( EV – PV )• Cost Variance (CV)

is a measure of cost performance on a project.

CV = ( EV – AC )


29

• Schedule performance index (SPI) Is a measure of progress achieved compared to progress planned on a the project.

SPI = ( EV / PV )

• Cost performance index (CPI) Is a measure of the value of work completed compared to the actual cost on the project.

CPI = ( EV / AC )


30

ExampleWe are about to produce 20 tables in 20 days cost is $20 for each.

How much BAC = ???BAC = $20 * 20 tables = $400

Today is day 4 How much is the PV ?PV = $20 x 4 tables = $80

At day 4 i earned only 3 tables, how much is the EV ?EV = $20 x 3 tables = $60AC = $90SV = EV – PV = 60 – 80 = -$20 CV =EV – AC = 60 – 90 = -$30SPI = EV / PV = 60 / 80 = 0.75CPI = EV / AC = 60 / 90 = 0.666


31

Forecasting

Estimate At Completion (EAC) actual costs incurred for work completed, plus an estimate to complete (ETC) the remaining work.

EAC = ( AC + ETC )

EAC forecast for ETC work performed at the budgeted rate

EAC = AC + ( BAC – EV ) = 90 + ( 400 – 60 ) = $430

EAC forecast for work performed at the percent CPI

EAC = BAC / CPI = 400 / .66 = $606.6

EAC forecast for ETC work considering both SPI and CPI factors

EAC = AC + [ ( BAC – EV ) / ( CPI * SPI ) ] = 90 + [ (400 – 60 ) / ( 0.75 * 0.66 ) ] = $868.68

Example - Wall Construction

Wall Construction

Time = 1 week per wall

Cost = $ 1,000 per wall, materials and labor

Total Schedule = 4 weeks

Total Cost = $ 4,000

Working days 5 day per week starting on Sunday and finish on Thursday by 5 PM

Assume production is liner

36

Wall 1 100% = $ 1,000

Wall 2 80% = $ 800

Wall 3 0% = 0

Wall 4 0% = 0

PV = $ 1,800

How much work should have been completed -PV?

37

Wall 1 100% = $ 1,000

Wall 2 50% = $ 500

Wall 3 10% = $100

Wall 4 0% = 0

Total = $1,600


What is the budgeted value of actual work - EV?

Total Cost to date –

AC = $ 2,250

5 pm Wednesday, Week 2 Earned Value

PV $1,800

EV $1,600

AC $2,250

Schedule Variance = EV - PV

= $1,600 - $1,800

= ($200)

Cost Variance = EV - AC

= $1,600 - $2,250

= ($650)

5 pm Wednesday, Week 2 Performance Indices

PV $1,800

EV $1,600

AC $2,250

SPI = EV / PV

= $1,600 / $1,800

= .9

CPI = EV / AC

= $1,600 / $2,250

= .7
