Budget and cost control Flashcards
Creating a budget?
- Plan how much money is needed (from estimates) to complete required scope to a certain quality. 2. Estimates used (to enable budget setting, create a resource schedule, support judgements of value for money). 3. Consider all types of cost and when they will hit. 4. Information required from external sources like supplier costs. 5. look at uncertainties and assumptions being made
CBS
cost breakdown structure - hierarchical structure used to organise project costs according to category, easier to track budget
Types of cost
Fixed/non-recurring - occurs once, non recurring, costs the same. variable/recurring dependent on how much product will be produced, occurs periodically. materials or monthly fees. Direct - associated with project work/scope specifically and has a direct impact. Indirect - like overheads, incurred by operating the business, required to support the project
Cost planning/funding linear
funding released only at decision gates, end of milestone. At business case, allows for funding to be pidgeonholed for project. will have resources allocated and costed at start. subject to change control if scope changes.can use a histogram to bottom up cost
cost planning iterative
- funding relaesed more requently - fixed cost for each timebox. 2. planning packages used to set aside work in larger chuncks which are converted into work packages.
Why monitor and control cost?
- can run out of money if don’t. 2. ensure project is still viable. 3. actively identify any variaitons. 4. used for decision making, identify problems. 5. identify areas of overspend. 6. inform future projects by providing insights for lessons learned
Elements of cost
1.Commitments like leases, money that is already been allocated to be spent on something specific. 2. accruals, work complete but not paid for yet. 3. forecast, plan for future help manage cashflow. 4. cashflow, get paid asap
Cost control techniques
- anticipated final cost. 2. cashflow forecasting. 3. EV analysis.
Earned Value
identifies difference between what we planned to spend, actual spend and value of deliverables so far - can see true performance of project.
PC, AC, BAC
planned cost, actual cost, budget at completion
EV, CV, SV
earned value (%completeXBAC), Cost variance (EV-AC), schedule variance (EV-PC)
CPI, SPI
cost performance index EV/AV (efficiency of spend), schedule performance index EV/PC (productivity
FCC, FTC
forcast cost at completion, BAC/CPI, forecast time at completion orginal duration/SPI
-CV, -SV
spending more than earned, behind plan (less productive)
+cv, +sv
spending less, ahead of plan, more productive, need less resources
