Many students asked me about "Project Estimate" and "project budget" of the difference between the two calculations is mainly not tell any difference in the end there. First of all we want is in the PMBOK in Analysis, "estimate" and "budget" is a two month process, but also refers to two "action" does not mean "value" concept. In fact, the project estimate and budget were crossed, and not entirely separable. We decorated 80 square meters of housing to examples. First is estimated that there are three general ways: top-down, bottom-up and parameter method. Top-down, you just ask the same friends house decorated 80 square meters, according to this standard about how much money can be, and such fee is 5 million yuan to renovate; bottom-up, your own calculations, 80 square meters of floor tiles How much, how much money the wall, how much money kitchenware, home appliances how much money, how much artificial. Finally you figure out approximately 4.5 million; parameter method, you check about 4,500 yuan a square meter renovated a total of 80 square meters and 3.6 million; algorithm is different, of course, not estimates derived from the same, but every estimate method has a range of not very accurate, so the range of estimates are quite common with the actual bias (-50% +75%). Look at the budget: the budget process is different, first you must fitting into several activities, such as fitting bathrooms, living room decoration, decoration bedroom. Then you have to be estimated for each event (also has a precision problem), then estimates for each activity summary, drawn from the budget value, the value obtained after the budget, you still have to time or in accordance with the activities in accordance with re- points down, so as to complete the budget process, so get the budget baseline. From the above we can see, the budget estimates of the activities actually carried out the thinning, or estimate the nature of a summary and further decomposition, while the budget in the degree of accuracy than the accuracy of estimates. Estimates are generally used for project approval, as long as the client or sponsor can be considered acceptable, while the specific implementation of the budget unit is used to control the cost, which is the benchmark to establish the budget, so the output is the budget baseline budget.

Mnogi studenti pitao me o "Project procjena" i "proračun projekta" od razlika između dva kalkulacije uglavnom ne reći sve razlike na kraju tamo. Prije svega želimo se u PMBOK u analizi, "procjena" i "proračun" je dva mjesec proces, ali i odnosi se na dvije "akcija" ne znači "vrijednost" koncept. U stvari, procjena projekta i proračuna bili su prešli, a ne potpuno podijeliti. Mi uređena 80 metara kvadratnih stambenog primjerima. Prvo se procjenjuje da postoje tri opće načina: top-down, bottom-up i parametar metode. Top-down, vi samo pitajte isti prijatelj kuća uređena 80 četvornih metara, u skladu s ovom standardnom o tome koliko novaca se može, i takva naknada je 5 milijuna juana za renoviranje, odozdo prema gore, vlastiti izračuni, 80 četvornih metara podnih pločica Koliko, koliko novaca zid, koliko novaca posuđe, kućanski aparati koliko novaca, koliko umjetnog. Napokon možete shvatiti oko 4,5 milijuna, parametar metode, te provjeriti oko 4.500 juana četvornih metara obnovljena ukupno 80 četvornih metara i 3,6 milijuna kuna; algoritam je drukčiji, naravno, ne procjene dobivene iz iste, ali svaka procjena metoda ima niz ne vrlo precizne, tako da raspon procjene su prilično uobičajene i stvarne pristranosti (-50% +75%). Pogledajte proračun: proračunski proces je drugačiji, najprije morate uklopiti u nekoliko aktivnosti, kao što dolikuje kupaonice, dnevni boravak dekoracija, dekoracija soba. Zatim morate se procijeniti za svaki događaj (također ima precizni problema), a zatim procjene za svaku aktivnost sažetak, izvučeni iz proračuna vrijednosti, vrijednosti dobivene nakon proračuna, još uvijek imate na vrijeme ili u skladu s aktivnostima u skladu s re- bodova prema dolje, tako da se kompletan proces proračuna, tako da bi proračuna osnovica. Iz navedenog možemo vidjeti, proračun procjene aktivnosti stvarno provele doradu, prirodi ili procijenjena ukupna a zatim razlaže u stupanj točnosti veća od točnosti predviđanje proračuna. Procjene se uglavnom koriste za odobrenjem projekata, sve dok stranka ili sponzor može se smatrati prihvatljivom, dok je specifični provedbe proračuna jedinica koristi se za kontrolu troškova, što je preduvjet treba osnovati proračun, tako da izlaz je proračun proračuna osnovica.
