At the end of this chapter… Define project cost terms and tell how each is used in estimating project cost. Compare and contrast analogous, parametric, and bottom-up methods of estimating cost. Describe issues in project cost estimating and how to deal with each. Create a time-phase bottom-up budget for a project. Show summary and bottom-up project budget information with cumulative costs using MS Project.

Introduction to Project Budgeting Involves developing a cost management plan for a project For small projects –Ensure accurate cost estimates –Secure the funding –Develop cost reporting procedures For large projects –AND develop and use accurate cash flow estimates Cost management plan – “the document that sets out the format and establishes the activities and criteria for planning, structuring, and controlling the project costs.” PMBOK® Guide

Purposes of the Cost Management Plan How to develop and share relevant, accurate and timely information for decision making Provides feedback linking the project to business objectives Provides detail and summary information Helps project stakeholders focus on schedule, performance, and cost.

Estimate Cost Cost estimating is linked to scope, schedule, and resource planning Never lie to yourself –You must understand what the project costs really are Never lie to anyone else –Avoid shading the truth to secure necessary funding Cost estimating – “the process of developing an approximation of the cost of the resources needed to complete project activities.” PMBOK® Guide

Types of Costs – Direct vs. indirect Direct costs only occur because of the project –Direct labor –Other direct costs – material, travel, consultants, subcontracts, purchased parts, computer time Indirect costs are necessary costs not associated with one specific project –Salaries, buildings, utilities, insurance, clerical assistance –Costs are allocated across projects

Types of Costs – Recurring vs. Nonrecurring Recurring costs repeat as the project work continues –Cost of writing cost; laying bricks –Occur during project evaluation Nonrecurring costs happen only once during a project –Design development –Occur during project planning and closing

Types of Costs – Estimate vs. Contingency reserve Project estimates need to be aggressive Add a reserve to cover activities that run over aggressive estimates Estimate – “a quantified assessment of the likely amount… It should always include an indication of accuracy.” PMBOK® Guide Reserve – “a provision in the project management plan to mitigate cost and/or schedule risk. Often used with a modifier (e.g. management reserve, contingency reserve) to provide further detail on what types of risk are meant to be mitigated.”PMBOK® Guide

Analogous Estimating Consider a similar project as a cost estimating starting point Requires experience performing similar projects and actual cost of similar projects Knowledge of how the proposed project differs from the previous project Experience with methods used to perform the project Analogous estimating – “an estimating technique that uses parameters such as size, weight or complexity from a previous similar activity as the basis for estimating the same parameter or measure for a future activity.” PMBOK® Guide

Bottom-Up Estimating Most detailed – specifications need to be very clear Time consuming Most accurate form of estimating Ensure every item is included Bottom-up estimating – “a method of estimating a component of work. The work is decomposed into more detail. An estimate is prepared of what is needed to meet the requirements of each of the lower, more detailed pieces of work, and these estimates are then aggregated into a total quantity for the project.” PMBOK® Guide

Supporting detail - Assumptions Workers will be paid at the prevailing wage rate of $14 per hour Workers are already familiar in general with the technology being used on the project Workers will be paid for 40 hours per week whether there is always that much work for them or not Overtime will never be authorized The project schedule can be delayed if the only alternative is to pay overtime.

Value Engineering Method of double-checking all of the chosen methods for accomplishing work and the features of the project deliverable A separate stage may be incorporated late in the project planning to ensure time is spent on value engineering 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.” PMBOK® Guide

Types of Accounting Systems Functional based accounting systems used historically –Overhead (indirect) costs were assigned to a cost pool allocated to direct costs based on volume Contemporary approach –Indirect costs form a larger percentage of total costs –Allocation of indirect costs is more carefully considered Activity-based costing allocates indirect costs to fixed costs
37

Activity-based Costing More involved methods for allocating indirect costs Yields more accurate cost information Cost Drivers: Number of units produced Number of batches run Number of product variations Amount of facility utilized

Time Value of Money Discounting the value of future revenue and cost streams will enable better project decisions Discount future dollars by the appropriate factor The finance department may provide the appropriate rate The rate depends on the underlying inflation rate plus the cost of capital

Determine Budget Aggregating costs Analyzing reserve needs Determining cash flow Determine budget – “the process of aggregating the estimated costs of individual activities or work packages to establish an authorized cost baseline.” PMBOK® Guide
41

Aggregating Costs Direct and indirect costs add up to the cost baseline The cost baseline is an integral part of the project management plan The cost baseline can only be changed through a formal change management process Cost performance baseline – “a specific version of a time-phased budget used to compare actual expenditures to planned expenditures to determine if preventive or corrective action is needed to meet the project objectives.” PMBOK® Guide

Analyzing Reserve Needs
44
© 2012 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part. Analyzing Reserve Needs Known knowns are discovered during planning and can be estimated directly Known unknowns are discovered during risk identification Unknown unknowns (unk unks) are totally unexpected occurrences that cause an increase in cost and/or schedule –The money used to cover unk unks is called management reserve
45
© 2012 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part. Analyzing Reserve Needs The amount placed into contingency reserve is calculated during risk analysis The amount placed into management reserve is determined by how much uncertainty management feels exists in the project The cost baseline, contingency reserve, and management reserve are used to determine if sufficient funds are available

Determining Cash Flow Expenses are applied to individual activities in the schedule to see when cash is needed Cash may be supplied through organization budgets on a periodic basis The cumulative amount of cash coming in to the project must meet or exceed demands for cash payouts

Summary Cost budgeting includes aggregating individual costs, analyzing needs for cost reserves where uncertainty exists, and determining cash inflow and outflow. Establishing cost controls includes establishing cost reporting systems. MS Project can assist in developing either bottom-up project budgets or summary project budgets.

The Value of Budget Optimization At a major midwestern electric utility a three-year capital project portfolio is developed for implementation and budgeted. The budgeting process itself is conducted year- round in an endeavor to balance multiple competing objectives The utility adopted a project portfolio optimization process to create, analyze, refine the budget for the portfolio PM in Action Example
