Study on Cost Management

Description
In production, research, retail, and accounting, a cost is the value of money that has been used up to produce something, and hence is not available for use anymore.

Traditional Cost Management vs. Earned Value Cost Management
There is an important and fundamental difference between the data available for analysis in a:

In Summary
Traditional Cost Management provides:
? ?

How much money and time a particular job is likely to require prior to starting and once started How much money was spent at any given time.

EVM Cost Management adds:
?

What work has been accomplished to date for the funds expended (what you got for what you spent)

What is Cost Management?
“Includes the processes required to ensure that the project is completed with the approved budget” PMBOK Guide 2004

What are the Cost Management Processes?
PROJECT COST MANAGEMENT
7.1 Cost Estimating
.1 Inputs .1 Enterpirse environmental factors .2 Organizational process assets .3 Project scope statement .4 Work breakdown structure .5 WBS dictionary .6 Project management plan -Schedule management plan -Staffing management plan -Risk register .2 Tools and Techniques .1 Analogous estimating .2 Determine resource cost rates .3 Bottom-up estimating .4 Parametric estimating .5 Project management software .6 Vendor bid analysis .7 Reserve analysis .8 Cost of quality .3 Outputs .1 Activity cost estimates .2 Activity cost estimate detail .3 Requested changes .4 Cost management plan (updates)

7.2 Cost Budgeting
.1 Inputs .1 Project scope statement .2 Work breakdown structure .3 WBS dictionary .4 Activity cost estimates .5 Activity cost estimate detail .6 Project Schedule .7 Resource Calendars .8 Contract .9 Cost Management Plan .2 Tools and Techniques .1 Cost aggregation .2 Reserve analysis .3 Parametric estimating .4 Funding limit reconciliation .3 Outputs .1 Cost baseline .2 Project funding requirements .3 Cost management plan (updates) .4 Requested changes

What will you do with the cost information when the job is done?
?

WBS and level of cost collection should consider not only the natural division of work but also consider future use of cost information
? ? future proposals comparative cost analysis - “best method of performance”

? Develop a “going-in” strategy

Document Cost Baseline

Develop Cost Management Plan
•Management of Cost Variances •Cost Change Control •Performance Measurement

or plan on not just how to control overruns but how to reduce costs: ? ? ? Incentives Competitive Procurements Methods Improvements
• • • • Questioning Attitudes Technology Deployment Value Engineering Trade-off Analysis

12

Are any performance measurement techniques placing you at risk?
?

Contract payment schedules are often tied to your WBS structure and chosen earned value techniques
? Consider potential work suspension and resumption risks
• Should PM/CM activities be modified milestones versus level of effort?

?

Consider learning curves
• • • less experience (early in contract) - higher cost/unit more experience (later in contract) - lower cost/unit improvement comes with practice

Change is inevitable, success is optional
-Yogi Berra

so Plan for Success

What is your plan for controlling internal change?
?

Evaluate cost uncertainty and your risk events upfront
? Establish a reserve and develop risk mitigation plans

?

Monitor cost and schedule performance for deviations Accurately record changes to the baseline Bring expected costs within acceptable limits

What is your plan for controlling external change?
?

Monitor correspondence/field direction

? Monitor cost and schedule performance for variances ? Isolate change impacts (scope, schedule, and cost) ? Inform stakeholders of changes

?
?

Agree to a Not-to-Exceed Value

Document changes
? ? ? Schedule Performance reports Field notes/logs
Scope

After the smoke clears, it is not necessarily what was As-Planned said and Schedule/ done by either Cost Estimate Work party that determines the Performance Breakdownoutcome; it is what the Reporting Structure Variance Reports As-Built documents say was Daily Logs Schedule/ Change Notices said or done. Actual Costs

? Timely negotiations
