E N D
Cost Management • Cost estimating • Cost accounting • Project cash flow • Company cash flow • Direct labor costing • Overhead rate costing • Others, such as incentives, penalties, and profit-sharing
Cost Control Requirements • Measure resources consumed • Measure status and accomplishments • Compare measurements to projections and standards • Provide the basis for diagnosis and re-planning
Cost Control Requirements (Continued) • Frequent, periodic comparison of actual progress and expenditures to schedules and budgets, both at the time of comparison and at project completion
WHEN TO IMPLEMENT A COST MANAGEMENT SYSTEM Possible cost reductions Cost of change PROJECT COSTS CONCLUSION A cost management system should be implemented right at the beginning of the life cycle of the project. PROJECT LIFE CYCLE PHASES

Sources Of Additional Funding • Funded contract change • Management reserve • Undistributed budget (money waiting to be allocated)
Cost Data • Labor • Material • Other direct charges • Overhead
VARIABLES FOR VARIANCE ANALYSIS • BUDGETED COST FOR WORKED SCHEDULED (BCWS) IS THE BUDGETED AMOUNT OF COST FOR WORK SCHEDULED TO BE ACCOMPLISHED PLUS THE AMOUNT OF LEVEL OF EFFORT. • BUDGETED COST FOR WORK PERFORMED (BCWP)IS THE BUDGETED AMOUNT OF COST FOR COMPLETED WORK, PLUS BUDGETED FOR LEVEL OF EFFORT OR APPORTIONED EFFORT ACTIVITY COMPLETED WITHIN A GIVEN TIME PERIOD. THIS IS SOMETIMES REFERRED TO AS AN “EARNED VALUE.” • ACTUAL COST FOR WORK PERFORMED (ACWP) IS THE AMOUNT REPORTED AS ACTUALLY EXPENDED IN COMPLETING THE WORK ACCOMPLISHED WITHIN A GIVEN TIME PERIOD. • COST VARIANCE = BCWP – ACWP • SCHEDULE/PERFORMANCE VARIANCE = BCWP - BCWS
Variances • The cost variance compares deviations only from the budget and does not provide a measure of comparison between work scheduled and work accomplished. • The scheduling variance provides a comparison between planned and actual performance but does not include costs.
Measurements • Measurable efforts: discrete increments of work with a definable schedule for accomplishment, whose completion produces tangible results. • Level of effort: work that does not lend itself to subdivision into discrete scheduled increments of work, such as project support and project control.
COST VARIANCE CALCULATION A NEGATIVE VARIANCE INDICATES A COST OVERRUN CV = BCWP - ACWP
SCHEDULE VARIANCE CALCULATION SV = BCWP - BCWS A NEGATIVE VARIANCE INDICATES A BEHIND SCHEDULE CONDITION
VARIANCE PERCENTS SV SCHEDULE VARIANCE % = (SVP) COST VARIANCE % = (CVP) X 100 BCWS CV X 100 BCWP

Information Requirements • Budgeted cost for work scheduled (BCWS) • Budgeted cost for work performed (BCWP) • Actual cost for work performed (ACWP) • Estimated cost at completion • Budgeted cost at completion • Cost and schedule variances/explanations • Traceability

ESTIMATE AT COMPLETION (EAC) ACWP EAC = Budget at completion X BCWP (BAC) The estimate at completion is the best estimateof the total cost at the completion of the project. The EAC is a periodic evaluation of the status of the project - usually on a monthly basis or until a significant change has been identified.
Cost Problems • Poor estimating techniques and/or standards, resulting in unrealistic budgets • Inadequate work breakdown structure • No management policy on reporting and control practices • Poor work definition at the lower levels of the organization
