Sissejuhatus<\/h2>\n

IT valdkonnas ja eriti IT m\u00fc\u00fcgis t\u00f6\u00f6tades olen n\u00e4inud palju piloteerimise projekte, kuid enamik neist on l\u00f5ppenud t\u00fchjalt, suure ajakulu t\u00f5ttu.<\/p>\n

Samuti, kui r\u00e4\u00e4gime riistvara lahenduste testimisest, n\u00e4iteks andmesalvestusseadmest, siis igale demokeskkonnale on tavaliselt j\u00e4rjekord, mis ulatub peaaegu aastani ette. Iga testimine meie graafikus v\u00f5ib tuua m\u00fc\u00fcgi v\u00f5i vastupidi, m\u00fc\u00fcgi kaotada. Situatsioon, kus testimine ei m\u00f5juta m\u00fc\u00fcki, ei ole m\u00f5tet arutada, kuna ka testimine pole m\u00f5ttekas \u2014 see on t\u00fchine ajakulu ja demokeskkonna h\u00f5ivamine.<\/p>\n

Nii et kuidas siis k\u00f5ik \u00f5igesti teha, et k\u00f5ik juhtuks?
\n<\/a><\/noindex><\/p>\n

Ettevalmistus<\/h2>\n

Piloodi eesm\u00e4rgid<\/h3>\n

Kust algab piloot? Mitte seadmete \u00fchendamisest rackis, absoluutselt mitte. Enne seadmetega t\u00f6\u00f6tamist k\u00e4ib ettevalmistus dokumentidega. Alustame piloodi eesm\u00e4rkide m\u00e4\u00e4ratlemisest.
\nPiloodi eesm\u00e4rk on k\u00f5rvaldada l\u00f5ppkasutaja vastuv\u00e4ited. Kui vastuv\u00e4iteid pole \u2014 pole ka pilooti. Jah, just nii.
\nAga millised on peamised vastuv\u00e4idete klassid, mida me n\u00e4ha v\u00f5ime?
\n* Me kahtleme usaldusv\u00e4\u00e4rsuses
\n* Me kahtleme j\u00f5udluses
\n* Me kahtleme skaleeritavuses
\n* Me kahtleme \u00fchilduvuses ja suutlikkuses t\u00f6\u00f6tada meie s\u00fcsteemidega
\n* Me ei usu teie slaididesse ning soovime praktikas veenduda, et teie s\u00fcsteem seda t\u00f5eliselt suudab
\n* See k\u00f5ik saab olema v\u00e4ga keeruline, meie insenerid on juba koormatud ja neil on raske<\/p>\n

Kokkuv\u00f5ttes saame l\u00f5puks kolm p\u00f5hiliiki pilootkatsetust ja erijuhuna kontsepti t\u00f5endamist (PoC \u2013 proof of concept):
\n* Koormustestimine (+ skaleeritavus)
\n* Funktsionaalsuskatsetamine
\n* T\u00f5rkekindluse testimine<\/p>\n

Konkreetse juhtumi puhul, s\u00f5ltuvalt konkreetse tellija kahtlustest, v\u00f5ivad piloodis olla \u00fchendatud erinevad eesm\u00e4rgid v\u00f5i vastupidi, esineda ainult \u00fcks neist. <\/p>\n

Piloot algab dokumendist, mis selgitab eesti keeles, miks seda testimist viiakse l\u00e4bi. Samuti sisaldab see tingimata m\u00f5\u00f5detavaid kriteeriume, mis v\u00f5imaldavad \u00fcheselt \u00f6elda, kas piloot on edukalt l\u00e4bitud v\u00f5i mida t\u00e4pselt ei saavutatud. M\u00f5\u00f5detavad kriteeriumid v\u00f5ivad olla numbrilised (n\u00e4iteks viivitused millisekundites, IOPS) v\u00f5i binaarsed (jah\/ei). Kui teie piloodi kriteeriumide hulgas on m\u00f5\u00f5tmatu n\u00e4itaja \u2013 ei ole piloodi l\u00e4biviimine m\u00f5ttekas, see on puhtalt manipuleerimise t\u00f6\u00f6riist.<\/p>\n

Seadmed<\/h3>\n

Pilooti saab l\u00e4biviia kas tootja\/distriibutori\/partneri demoseadmetel v\u00f5i kliendi seadmetel. T\u00f5epoolest, erinevus on v\u00e4ike, \u00fcldine l\u00e4henemine on sama.<\/p>\n

Peamine k\u00fcsimus seadmete osas ENNE pilooti \u2013 kas k\u00f5ik vajalikud seadmed on kohal (sh l\u00fclitid, andmeedastuskaablid, toitekaablid)? Kas seadmed on testimiseks valmis (\u00f5iged tarkvaraversioonid, k\u00f5ik toega, k\u00f5ik tulukesed on rohelised)?<\/p>\n

Testimise eesm\u00e4rkide m\u00e4\u00e4ramise j\u00e4rel j\u00e4rgnev tegevuste j\u00e4rjestus on varustada testimiseks vajalikud seadmed enne nende edastamist kliendile. Loomulikult on ka m\u00f5ningaid usaldusv\u00e4\u00e4rseid kliente, kes ei kiirusta, kuid need on pigem erandid. See t\u00e4hendab, et kogu komplekt peab olema partnerite platsil kokku pandud, k\u00f5ik peab olema kontrollitud ja kokku pandud. Soovitatav on, et s\u00fcsteem oleks t\u00f6\u00f6le pandud ning te peaksite veenduma, et k\u00f5ik t\u00f6\u00f6tab, tarkvara laetakse ilma vigadeta jne. Tundub, et see pole keeruline, kuid 3 neljast pilootprojektist algab kaablite v\u00f5i SFP-transiiverite otsimisega.
\nErakordselt oluline on r\u00f5hutada, et demoversiooni kontrollimise k\u00e4igus peate veenduma selle puhtuses. K\u00f5ik varasemate testimise andmed peavad olema s\u00fcsteemist kohustuslikus korras kustutatud enne edastamist. Pole v\u00e4listatud, et katsetamine toimus reaalsete andmete p\u00f5hjal, kus v\u00f5ivad olla nii \u00e4risaladused kui ka isikuandmed.<\/p>\n

Testimistegevus<\/h3>\n

Enne seadmete edastamist tellijale peab olema kohustuslikult valmis testimise programm, mis vastab testimise eesm\u00e4rkidele. Igal testil peab olema m\u00f5\u00f5detav tulemus ja selged edutegurid.
\nTestimisprogramm v\u00f5ib olla koostatud tarnija, partneri, tellija v\u00f5i \u00fchiselt \u2013 kuid kindlasti enne testide algust. Tellija peab kohustuslikult allkirjastama, et see programm talle sobib.<\/p>\n

Inimesed<\/h3>\n

Piloodi ettevalmistamise k\u00e4igus tuleb kokku leppida piloodi l\u00e4biviimise kuup\u00e4evad ja k\u00f5igi vajalike isikute kohalolek ning nende valmisolek testimiseks, nii tarnija\/partneri kui ka tellija poolt. O, kui palju pilote on alustatud siis, kui peamine isik tellija juures l\u00e4heb j\u00e4rgmisel p\u00e4eval p\u00e4rast seadmete paigaldamist puhkusele!<\/p>\n

Kohustuste \/ ligip\u00e4\u00e4su sf\u00e4\u00e4rid<\/h3>\n

Piloodi programmis peavad olema selgelt m\u00e4\u00e4ratletud ja ideaalis ka kirja pandud k\u00f5igi osalejate vastutusalad. Kui vaja, tuleks koosk\u00f5lastada kaugor v\u00f5i f\u00fc\u00fcsiline ligip\u00e4\u00e4s tarnija\/partneri inseneridele tellija s\u00fcsteemidele ja andmetele tellija turvateenistuse kaudu.<\/p>\n

Piloot<\/h2>\n

Kui oleme t\u00e4itnud k\u00f5ik eelnevad punktid, siis k\u00f5ige igavam osa on ise pilot. Kuid see peab kulgema nagu r\u00f6\u00f6baste peal. Kui ei, siis t\u00e4hendab see, et ettevalmistuses on midagi valesti.<\/p>\n

Piloodi l\u00f5petamine<\/h2>\n

Piloodi l\u00f5petamisel koostatakse dokument tehtud testide kohta. Ideaalis peaks k\u00f5ik testid olema programmis rohelise linnukesega L\u00c4BIDUD. On v\u00f5imalik ette valmistada esitlus k\u00f5rgemale juhtkonnale, et saada heakskiit ostuotsusest v\u00f5i lisamisest lubatud s\u00fcsteemide nimekirja.
\nKui teil ei ole piloodi l\u00f5pus dokumenti l\u00f5petatud testide loetelu ja m\u00e4rkustega l\u00e4bitud \u2013 on piloot eba\u00f5nnestunud ja seda ei oleks pidanud \u00fcldse alustama.
