Teknik Determine Budget
Metode Analogous
Metoda Parametrik
Metoda Bottom Up, dengan menggabungkan
biaya per aktivitas (Estimate Cost). TeknikEstimate Cost didasarkan atas sumber daya(resource based) : Tentukan Sumberdaya aktifitas (resource)
Material, Tenaga Kerja, Peralatan, dll Hitung biaya sumberdayanya
Hitung biaya aktifitasnya

The earned value technique in its various forms is acommonly used method of performance measurement
It integrates project scope, cost, and schedulemeasures to help the project management team assessproject performance
The EVM methodology integrates scope, schedule, and
resources, to objectively measure projectperformance and progress

EVM Parameters
PLAN ACTUAL
PV(Planned value)
EV(Earn Value)
AC(Actual Cost)
Planned Valuethe authorized budget assigned to the schedule work to
be accomplished for a schedule activity or work breakdown structurecomponent
Earn Valueis the value of work performed expressed in terms of theapproved budget assigned to that work for a schedule activity or workbreakdown structure component
Actual Costis the total cost actually incurred and recorded inaccomplishing work performed for a schedule activity or workbreakdown structure component

Alternative 1 :EAC = Actual + Remaining Budget = AC + (BAC EV)Use when current variances are thought to be atypical of the future
Alternative 2 :EAC = Actual + Remaining Budget/CPI = AC + (BAC EV) / CPIUse when current variances are thought to be typical of the future
Alternative 3 :EAC = Actual + Remaining/CPI/SPIWorst case scenario
Alternative 4:EAC = BAC / CPI
Used when if no variances from the BAC have occurred orwill continue at the same rate of spending
Alternative 5:EAC = Actual + New Estimate for Remaining Budget = AC + ETCUse when original estimate was fundamentally flawed
