Project implementation is often hindered by a number of problems, including a long preparation and start-up phase, which makes the project design outdated by the time implementation starts and significantly reduces the time available for implementation.
Sageli takistavad projekti rakendamist mitmed probleemid, kaasa arvatud projekti pikk ettevalmistus- ja käivitamisetapp, mille tõttu aegub projekti kavand enne rakendamise algust ja projekti rakendamiseks kasutatav aeg lüheneb oluliselt.
