Pali mazana a zolemba pa intaneti zokhuza maubwino osanthula machitidwe a kasitomala. Nthawi zambiri izi zimakhudza gawo lazogulitsa. Kuchokera kusanthula basket basket, kusanthula kwa ABC ndi XYZ mpaka kutsatsa kosungirako komanso zotsatsa zanu. Njira zosiyanasiyana zakhala zikugwiritsidwa ntchito kwa zaka zambiri, ma algorithms adaganiziridwa, code idalembedwa ndikusinthidwa - itenge ndikuigwiritsa ntchito. Kwa ife, vuto limodzi lalikulu lidabuka - ife ku ISPsystem tikugwira ntchito yopanga mapulogalamu, osati ogulitsa.
Dzina langa ndine Denis ndipo pano ndikuyang'anira kumbuyo kwa ma analytical systems ku ISPsystem. Ndipo iyi ndi nkhani ya momwe mnzanga ndi ine - omwe ali ndi udindo wowonera deta - adayesa kuyang'ana mapulogalamu athu apulogalamu kudzera mu chidziwitso ichi. Tiyeni tiyambe, monga mwachizolowezi, ndi mbiriyakale.
Pachiyambi panali mawu, ndipo mawu akuti "Kodi tiyese?"
Panthawiyo ndinali ndikugwira ntchito yokonza mapulani mu dipatimenti ya R&D. Zonse zidayamba pomwe Danil adawerenga pano pa HabrΓ© - chida chowunikira kusintha kwa ogwiritsa ntchito. Ndinkakayikira pang'ono za lingaliro logwiritsa ntchito pano. Monga zitsanzo, omanga laibulale adatchulapo kuwunika kwa ntchito zomwe zomwe mukufuna zidafotokozedwa bwino - kuyitanitsa kapena kusintha kwina kwa momwe angalipire eni ake. Zogulitsa zathu zimaperekedwa pamalopo. Ndiko kuti, wogwiritsa ntchito amagula laisensi poyamba, ndiyeno pokhapo amayamba ulendo wake wogwiritsa ntchito. Inde, tili ndi mitundu yama demo. Mukhoza kuyesa mankhwala kumeneko kuti musakhale ndi nkhumba mu poke.
Koma zambiri mwazinthu zathu zimangoyang'ana msika wochititsa chidwi. Awa ndi makasitomala akuluakulu, ndipo dipatimenti yopititsa patsogolo bizinesi imawalangiza za kuthekera kwazinthu. Zimatsatiranso kuti panthawi yogula, makasitomala athu amadziwa kale mavuto omwe mapulogalamu athu angawathandize kuthetsa. Njira zawo zogwiritsira ntchito ziyenera kugwirizana ndi CJM yomwe ili muzogulitsa, ndipo mayankho a UX adzawathandiza kukhalabe panjira. Wowononga: Izi sizichitika nthawi zonse. Mawu oyamba ku laibulale anaimitsidwa ... koma osati kwa nthawi yayitali.
Chilichonse chinasintha ndi kutulutsidwa kwa chiyambi chathu - - nsanja zopangira malo ogulitsira pa intaneti kuchokera ku akaunti ya Instagram. Mu pulogalamuyi, wosuta adapatsidwa nthawi ya masabata awiri kuti agwiritse ntchito zonse kwaulere. Ndiye munayenera kusankha ngati mungalembetse. Ndipo izi zimagwirizana bwino ndi lingaliro la "njira yofuna kuchitapo kanthu". Anaganiza kuti: tiyeni tiyese!
Zotsatira zoyamba kapena komwe mungapeze malingaliro
Gulu lachitukuko ndi ine tinalumikiza mankhwalawa ndi dongosolo lotolera zochitika m'tsiku limodzi. Ndidzanena nthawi yomweyo kuti ISPsystem imagwiritsa ntchito dongosolo lake losonkhanitsa zochitika zokhudzana ndi maulendo a masamba, koma palibe chomwe chimakulepheretsani kugwiritsa ntchito Yandex.Metrica pazifukwa zomwezo, zomwe zimakulolani kutsitsa deta yaiwisi kwaulere. Zitsanzo zogwiritsira ntchito laibulale zinaphunziridwa, ndipo patatha sabata imodzi yosonkhanitsa deta tinalandira graph yosinthira.
Chithunzi chosinthira. Ntchito zoyambira, zosintha zina zimachotsedwa kuti zimveke bwino
Zinakhala ngati mu chitsanzo: planar, zomveka, zokongola. Kuchokera pa graph iyi, tinatha kuzindikira mayendedwe omwe amapezeka pafupipafupi komanso kuwoloka komwe anthu amakhala nthawi yayitali kwambiri. Izi zidatipangitsa kumvetsetsa izi:
- M'malo mwa CJM yayikulu, yomwe imakhudza magawo khumi ndi awiri, awiri okha ndi omwe amagwiritsidwa ntchito mwachangu. Ndikofunikira kuwongolera ogwiritsa ntchito kumalo omwe tikufuna kugwiritsa ntchito mayankho a UX.
- Masamba ena, opangidwa ndi opanga UX kuti akhale otsiriza mpaka kumapeto, amathera ndi anthu omwe amathera nthawi yochulukirapo pa iwo. Muyenera kudziwa zomwe zoyimitsa zili patsamba linalake ndikuzisintha.
- Pambuyo pakusintha kwa 10, 20% ya anthu adayamba kutopa ndikusiya gawolo mukugwiritsa ntchito. Ndipo izi zikuganiziranso kuti tinali ndi masamba ofikira 5 mu pulogalamuyi! Muyenera kuzindikira masamba omwe ogwiritsa ntchito nthawi zonse amasiya magawo ndikufupikitsa njira yopita kwa iwo. Zabwinonso: zindikirani njira zilizonse zokhazikika ndikulola kusintha mwachangu kuchokera patsamba loyambira kupita patsamba lomwe mukupita. Chinachake chofanana ndi kusanthula kwa ABC ndi kusanthula kwamagalimoto osiyidwa, simukuganiza?
Ndipo apa tidawonanso momwe tingagwiritsire ntchito chida ichi pazinthu zapanyumba. Anaganiza zowunikira chinthu chomwe chimagulitsidwa ndikugwiritsidwa ntchito - . Ndizovuta kwambiri, pali dongosolo la kukula kwa mabungwe. Tinali kuyembekezera mwachidwi kuti tiwone momwe kusintha kwasinthira kudzakhala.

Analytics automation
Mu chimodzi mwazowonetsa zotsatira, tidawonetsa momwe Gephi amagwiritsidwira ntchito posanthula ma graph. Mu chida ichi, kutembenuka deta akhoza anasonyeza tebulo. Ndipo mkulu wa dipatimenti ya UX adanena lingaliro limodzi lofunika kwambiri lomwe lidakhudza chitukuko cha machitidwe onse a kampani: "Tiyeni tichite zomwezo, koma ku Tableau ndi zosefera - zidzakhala zosavuta."
Kenaka ndinaganiza: bwanji, Retentioneering imasunga deta yonse mu pandas.DataFrame structure. Ndipo ili, mokulira, ndi tebulo. Umu ndi momwe ntchito ina idawonekera: Wopereka Data. Iye sanangopanga tebulo kuchokera pa graph, komanso anawerengera momwe tsambalo likutchuka ndi ntchito zomwe zimagwirizanitsidwa ndi izo, momwe zimakhudzira kusungidwa kwa ogwiritsa ntchito, momwe ogwiritsa ntchito amakhalira nthawi yayitali, ndi masamba omwe ogwiritsa ntchito amachoka nthawi zambiri. Ndipo kugwiritsa ntchito zowonera mu Tableau kunachepetsa mtengo wowerengera graph kotero kuti nthawi yobwereza yowunikira machitidwe muzogulitsa idatsala pang'ono kuchepetsedwa.
Danil alankhula za momwe chiwonetserochi chikugwiritsidwira ntchito komanso zomwe zimalola kuti tipeze.
Magome ochulukirapo a mulungu wa tebulo!
Mu mawonekedwe osavuta, ntchitoyi idapangidwa motere: onetsani graph yosinthira mu Tableau, perekani kuthekera kosefa, ndikupangitsa kuti ikhale yomveka komanso yosavuta momwe mungathere.
Sindinkafuna kujambula graph yolunjika ku Tableau. Ndipo ngakhale atapambana, phindu, poyerekeza ndi Gefi, silinawonekere. Tinkafuna chinthu chosavuta komanso chopezeka mosavuta. Table! Kupatula apo, graph imatha kuyimiridwa mosavuta ngati mizere ya tebulo, pomwe mzere uliwonse uli m'mphepete mwa mtundu wa "source-kupita". Komanso, takonzekera kale tebulo lotereli pogwiritsa ntchito zida za Retentioneering ndi Data Provider. Zomwe zidatsala ndikuwonetsa tebulo mu Tableau ndikufufuza lipotilo.
Kulankhula za momwe aliyense amakonda matebulo.
Komabe, pano tikukumana ndi vuto lina. Zoyenera kuchita ndi gwero la data? Zinali zosatheka kulumikiza pandas.DataFrame; Tableau ilibe cholumikizira chotero. Kukweza maziko osiyana osungira graph kumawoneka ngati yankho lamphamvu kwambiri lokhala ndi chiyembekezo chosadziwika bwino. Ndipo njira zotsitsira m'deralo sizinali zoyenera chifukwa chosowa ntchito zamanja nthawi zonse. Tinayang'ana mndandanda wa zolumikizira zomwe zilipo, ndipo maso athu adagwera pa chinthucho , amene anaunjikana mwamanyazi pansi.
