What are the 4 processes for the Cost Management KA
1. Plan Cost Management (Planning) 2. Estimate Costs (Planning) 3. Determine Budget (Planning) 4. Control Costs (Monitoring and Controlling)
Resource Calendar
A calendar that identifies the working days and shifts on which each specific resource is available.
Discounted Cash Flow
A cash flow analysis based on time value for money
Risk Register
A document in which the results of risk analysis and risk response planning are recorded. (Input to Estimate Cost and Determine Budget)
Management Reserves
A lump sum used to accommodate unknown risks or unidentified risks. Cost baseline + Management Reserves = Cost Budget Amount of the project budget withheld for management control purposes and are reserved for unforeseen work that is within scope of the project. Intended to address the unknown unknowns that can affect a project. When it is used to fund unforeseen work, the amount used is added to the cost baseline, thus requiring an approved change to the cost baseline.
Schedule Performance Index (SPI)
A measure of schedule efficiency expressed as the ratio of earned value to planned value. It measures how efficiently the project team is using its time. We are only progressing at X percent of the rate originally planned >1 = Good, more work completed than planned. < 1 = Bad, less work completed than planned.
Schedule variance (SV)
A measure of schedule performance expressed as the difference between the EV and the PV. The amount by which the project is ahead or behind the planned delivery date, at a given point in time. As of today , how far behind or ahead of schedule are we?
Cost Performance Index (CPI) defined
A measure of the cost efficiency of budgeted resources expressed as the ratio of earned value to actual cost. Most critical EVA metric, it measures the cost efficiency for the work completed. We are getting $X worth of work out of every $1 spent. Funds are or are not being used efficiently. >1 = Good, cost underrun for work completed < 1 = Bad, cost overrun for work completed.
To-complete performance index (TCPI)
A measure of the cost performance that is required to be achieved with the remaining resources in order to meet a specified management goal, expressed as the ratio of the cost to finish the outstanding work to the remaining budget.
Earned Value (EV) (Replaced by Earned Schedule)
A measure of work performed expressed in terms of the budget authorized for that work. It is the budget associated with the authorized work that has been completed. It cannot be greater than the authorized PV budget. Often used to calculate the percent complete of a project. Hint: As of today, what is the estimated value of the work actually accomplished.
Cost of Quality
A method of determining the costs incurred to ensure quality. (T&T Estimate Cost & Plan Quality Mgmt)
Bottom-up estimating
A method of estimating project duration or cost by aggregating the estimates of the lower-level components of the work breakdown structure (WBS). A method of estimating a component of work. The cost of individual work packages or activities is estimated to the greatest level of specified detail. The detailed cost is then summarized or "rolled up" to higher levels for subsequent reporting and tracking purposes.
Earned value management
A methodology that integrates the scope baseline with the schedule, and cost baseline to form the performance measurement baseline. EVM develops and monitors 3 key dimensions for each work package and control account 1. Planned Value 2. Earned Value 3. Actual costs. Measurements resulting from earned value analysis indicate whether there are any potential deviations from the performance measurement baseline. expanded to include concept of Earned Schedule (ES)
Variance at Completion
A projection of the amount of budget deficit or surplus, expressed as the difference between the budget at completion and the estimate at completion. As of today, how much over or under budget do we expect to be at the end of the project?
Variance Analysis
A technique for determining the cause and degree of difference between the baseline and actual performance. As used in EVM, it is the explanation (cause impact, and corrective actions) for : cost (CV=EV - AC) schedule (SV = EV - PV) and Variance @ completion: (VAC = BAC - EAC) variances.
Analogous Estimating or Top-Down Estimating

Value Analysis (value engineering)
An approach used to optimize project life cycle costs, save time, increase profits, improve quality, expand market share, solve problems, and/or use resources more effectively. Technique to find a less costly way to do the same work. Systematically identify required project functions, assign values to those functions, and provide functions at the lowest cost without loss of performance
Performance Measurement baseline (PMB)
An approved plan for the project work to which the project execution is compared, and deviations are measured for management control. It typically integrates scope, schedule, and cost parameters of a project, but may also include technical and quality parameters. An approved, integrated scope-schedule-cost plan for the project work against which project execution is compared to measure and manage performance. The PMB includes contingency reserve, but excludes management reserve. Used with Earned value analysis.
Parametric estimating
An estimating technique in which an algorithm is used to calculate cost or duration based on historical data and project parameters. It uses a statistical relationship between relevant historical data and other variables (e.g., square footage in construction) to calculate a cost estimate for project work.
Project Schedule
An output of a schedule model that presents linked activities with planned dates, durations,milestones, and resources. The project schedule includes planned start and finish dates for the project's activities, milestones, work packages, and control accounts.
Vendor Bid Analysis
Analysis of what the project should cost, based on the responsive bids from qualified vendors. (T&T Estimate Cost)
Analytical Techniques
Analytical Techniques that can be used in the context of Plan Cost Management include: Payback period: How long it will take to recover amount invested in a project. Discount rate is NOT taken into account in calculations for payback period. Return on Investment (ROI) Internal Rate of Return (IRR): the discount rate that makes the net present value equal 0. Discounted Cash Flow: a cash flow analysis based on time value for money. Technique is uses in project selection to estimate attractiveness of an investment by predicting how much money will be received in future and then discounting it to its current value. Net Present Value: Calculated by discounting all future income amounts based on the discount rate and adding the discounted income stream. Net Present Value calculation = (Cash flow amount) / ((1 + Discount Rate) to the power of number of years)
Payback/Project Cost
Benefit Cost Ratio Formula
Three-Point Estimating - Schedule
Concept that originated with the program evaluation and review technique (PERT). PERT uses three estimates to define an approximate range for an activity's duration: • Most likely (tM). This estimate is based on the duration of the activity, given the resources likely to be assigned, their productivity, realistic expectations of availability for the activity, dependencies on other participants, and interruptions. • Optimistic (tO). The activity duration based on analysis of the best-case scenario for the activity. • Pessimistic (tP). The activity duration based on analysis of the worst-case scenario for the activity.
