Kuti muwongolere mtengo wopangira mankhwala ndikusunga zotulutsa zapamwamba kwambiri, muyenera kujambula madzi oyimira njira kuti muwunikenso ma labotale pafupipafupi. Sampling (yomwe imadziwikanso kuti sampuli za malo, sampuli zam'munda, kapena kusanja kwanzeru) imathandizira kutsimikizira momwe zinthu zimagwirira ntchito ndikuwonetsetsa kuti zomwe zapangidwa zikugwirizana ndi zomwe kasitomala akufuna.
Basic malamulo a zitsanzo
1: Chitsanzocho chiyenera kuimira ndondomeko ya boma, ndipo kafukufukuyo ayenera kugwiritsidwa ntchito kuchotsa chitsanzo kuchokera pakati pa chitoliro cha chitoliro kuti apewe kusintha kwa gawo panthawi ya kayendedwe ka chitsanzo.
2: Chitsanzocho chiyenera kukhala mu nthawi. Kufupikitsa nthawi yoyendetsa kuchokera kumalo ochotserako kupita ku labotale kumathandiza kuonetsetsa kuti ndondomekoyi ikuwonekera bwino.
3: Chitsanzocho chiyenera kukhala choyera. Pewani machubu akufa kumtunda kwa chidebe chachitsanzo ndi kulola kuyeretsa kokwanira ndi kupukuta makina opangira zitsanzo kuti muchepetse kuipitsidwa.
Taganizirani njira madzimadzi mmene mpweya kusungunuka. Ngati kutentha kukuwonjezeka ndi kupanikizika kumachepa, mpweya wosungunuka ukhoza kutuluka kuchokera mu chitsanzocho. Kapena ganizirani chitsanzo cha gasi chokhala ndi kutentha kochepa komanso kuthamanga kwambiri, zomwe zingapangitse madziwo kuti asokonezeke ndikusiyana ndi chitsanzo. Pazochitika zonse, mapangidwe a chitsanzo amasintha kwambiri, choncho sangathenso kuyimira ndondomekoyi.
Pazifukwa zomwe zili pamwambazi, ndikofunikira kugwiritsa ntchitozitsanzo mabotolokusonkhanitsa mpweya kapena mpweya wamadzimadzi kuti mukhalebe ndi gawo lolondola ndikusunga kuyimira kwachitsanzo. Ngati mpweya uli wapoizoni, silindayo imatetezanso katswiri wodziwa ntchito komanso chilengedwe ku utsi kapena utsi.
