Kala doorashada noocyada kala duwan ee qaybaha duntu waxay muhiim u tahay daacadnimada nidaamka. Codsiyada cadaadiska hooseeya ama dhexdhexaadka ah sida khadadka biyaha guriga, qaybinta gaaska (oo leh shaabadeeyayaal la ansixiyay), iyo waraabka,xirmooyinka duntaiyoalwaaxyadabixiyaan iska caabin daxalka aad u fiican iyo machinability. Goobaha wershadaha ee baahida badan leh ee ku lug leh kiimikooyinka, uumiga, ama cadaadiska sare, birta kaarboonka ee been abuurka ah ama alwaaxyada dunta birta-la'aanta ah ayaa ah heerka.
Furaha guusha waa rakibid habboon. Marka hore, hubi in duntu ay ku habboon tahay (tusaale, NPT, BSP). Had iyo jeer ka saar tuubada oo si fiican u nadiifi dunta. Codso cajalad daboolan ama ku dheji jihada saxda ah (saac u jihaysan marka aad eegayso dunta labka ah) kana fogow codsiga xad dhaafka ah, kaas oo sababi kara faddarayn gudaha waalka. Gacmaha- adkee marka hore, ka dibna isticmaal furayaasha si aad u gaadho taam sugan—sida caadiga ah hal ilaa laba leexasho Nidaamyada xadhkaha leh waxay ku fiican yihiin isku xirka qalabka, khadadka qalabka, iyo meel kasta oo la isku dhejiyo ayaa loo baahan yahay. Dib u isticmaalkooda iyo la qabsigooda ayaa ka dhigaya qayb aan laga maarmi karin oo ka mid ah qalab kasta oo dayactir ah iyo doorasho la isku halayn karo oo adag, shirarka tuubooyinka waara.
