UMBUZO

Why are deliveries late?

Phakamisani okumele kwenziwe, bese nahlulela ukuthi isenzo ngasinye singayithinta yini impande ngayinye.

Kufakwe uphawu ezinsukwini ezingu-40 ezedlule: leli gumbi alisazi ukuthi obani ababehlezi kulo; ngumphathi walo kuphela osashiwo ngegama. Lokho elakufinyelela kuyahlala.
abangu-30 etafuleni (29 abalingisiwe) · izenzo ezingu-3 ziphakanyiswe ngokumelene nezimbangela eziwumsuka ezingu-6. Engezani esisodwa, bese nahlulela ukuthi isenzo ngasinye siyayithinta yini imbangela ngayinye.
Nibuka njengesivakashi. Faka igama lomsebenzisi ukuze nijoyine futhi nihlanganyele.

Isiyingi singaba yinto yangempela etholakele — umjikelezo ozondlayo — noma isixhumanisi esingakaze sinqunywe ngempela ukuthi siya kuphi. Ibalazwe lithatha isiyingi njengendawo eyodwa, ngakho akukho okungaphakathi kwaso okuyimpande ngokwako. Uma kungokwesibili, kufanele isibhangqa sibuyiselwe egumbini.
Nikezani izimbangela eziwumsuka amaphuzu kuqala
kungani
Umkhuba wale ndlela uqobo, ngaphambi kokuthi kuphakanyiswe isenzo: imbangela ewumsuka ngayinye inikezwa amaphuzu angu-1–5 ngokuthi kuyenzeka kangakanani ukubhekana nayo, ukuthi ukubhekana nayo kungaba nomthelela ongakanani, nokuthi kungenzeka kangakanani ukuthi izixazulule yona ngaphandle kokungenelela. Okubalulekile kakhulu yizimpande ezinomthelela omkhulu, ezenzeka kalula futhi okungenzeki kalula ukuthi zizilungise — okubalulekile = umthelela + ukwenzeka − ukuzilungisa. Amaphuzu enziwa isilinganiso eqenjini lonke futhi aboniswa nokuthi bangaki abanikeze amaphuzu.
1 = phansi, 5 = phezulu. Amaphuzu enu; izilinganiso zeqembu eceleni kwawo.

Phansi ohlangothini: izenzo abantu abaziphakamisile. Phezulu: izimbangela eziwumsuka ezitholwe yibalazwe. Isikwele ngasinye siyivoti elilodwa embuzweni owodwa — ingabe lesi senzo singayinciphisa kakhulu leyo mbangela? Uhlangothi olulodwa kumele lufinyelele ku-75% wamavoti afakiwe ukuze kunqunywe; uma kungenjalo isikwele sihlala sihlukene. Isikwele ngasinye sibonisa ukuthi amavoti aso ahlukene kanjani — yebo / kubi nakakhulu / cha — futhi isikwele sinqunywa uma okukodwa kwalokho kufinyelela ezingxenyeni ezintathu kwezine zawo.
kungani
Kuphendulwe ngo-75% wamavoti afakiwe, njengayo yonke eminye imibuzo elapha. Kuhlukene kusho ukuthi abantu bavotile futhi alukho uhlangothi olufinyelele kulelo zinga — kungumphumela, hhayi uhlu lokulinda, futhi kuhlala kuhlukene kuze kube abantu abanele bashintsha imibono yabo. Isikwele esingenqunywa muntu sihlala singanqunyiwe; asikaze sibalwe njengokuthi “cha”. Ukwahlulela isibhangqa ngasinye ngokwaso yikho okuvimbela isenzo esithandwayo ukuthi sinconywe ngokulungisa izinto esingazithinti.

IZENZO EBALAZWENI
Kuboniswa: zonke izenzo igumbi elazahlulela. Kusebenza ngqo ku-5 kwezimbangela eziwumsuka ezingu-6. Akusebenzi ngqo ezimbangeleni eziwumsuka ezingu-1.
Kufundwe ezikweleni igumbi elazinquma esigabeni sezenzo, akukho okunye. Impande eluhlaza incishiswa okungenani yisenzo esisodwa kwezibonisiwe; empunga, akukho kuzo okusebenza kuyo ngqo; umugqa obomvu ojikelezayo usho ukuthi esinye sazo siyenza ibe imbi nakakhulu.

KUSUKA EZENZWENI KUYA OHLELWENI
Ithebula lahlulela isenzo ngasinye ngokwaso. Uhlelo luyiqoqo lazo igumbi elingazenza ndawonye.
Amalungu akha izinhlelo ngezenzo ezinciphisa imbangela ewumsuka, bese igumbi liqhathanisa izinhlelo ezimbili ngesikhathi, ngezingxenye ezintathu kwezine zamavoti afakiwe, njengoba lahlulela konke okunye. Uhlelo ngalunye lubonisa ukuthi yiziphi izimbangela eziwumsuka olusebenza kuzo ngqo, yiziphi olungasebenzi kuzo, nokuthi yiziphi oluzenza zibe zimbi nakakhulu.
Umphathi angavula ukuqhathaniswa kwezinhlelo.
Lokho esilindele ukuthi kulandele
Izibikezelo ngezenzo: lokho okufanele isenzo ngasinye sikushintshe, indlela yokukukala, nokuthi kuhlolwe nini. Ngalolo suku, umuntu owayesegumbini ubhala okwenzeke ngempela eduze kwaso.

Ibalazwe lisho ukuthi yiziphi izenzo ezithinta yiziphi izimbangela. Alisho ukuthi ukhona yini owazenza, noma kukhona okwashintsha. Okubhalwe lapha kuyisibikezelo esinosuku nento yokukala, esabhalwa ngemva kokuzinza kwebalazwe. Uma usuku lufika, okwenzeke ngempela kubhalwa eduze kwaso futhi isibikezelo sihlala njengoba sasinjalo: esingalungile yisona esiwusizo.
