Introducere<\/h2>\n

De-a lungul anilor de activitate \u00een domeniul IT \u0219i, \u00een special, \u00een v\u00e2nz\u0103rile IT, am v\u0103zut multe proiecte pilot, dar majoritatea dintre ele se \u00eencheiau cu nimic, dup\u0103 cheltuieli semnificative de timp.<\/p>\n

Astfel, dac\u0103 vorbim despre testarea solu\u021biilor hardware, cum ar fi stocarea de date, pentru fiecare sistem demo exist\u0103, de obicei, o a\u0219teptare de aproape un an \u00een avans. Iar fiecare testare \u00een program poate aduce o v\u00e2nzare sau, dimpotriv\u0103, poate afecta negativ o v\u00e2nzare. Nu are rost s\u0103 discut\u0103m despre o situa\u021bie \u00een care testarea nu influen\u021beaz\u0103 v\u00e2nzarea, deoarece nici testarea nu are sens - este o pierdere de timp \u0219i o ocupa\u021bie a sistemului demo.<\/p>\n

Deci, cum putem face totul \u00een mod inteligent pentru ca s\u0103 se \u00eent\u00e2mple?
\n<\/a><\/noindex><\/p>\n

Preg\u0103tire<\/h2>\n

Obiectivele pilotului<\/h3>\n

De unde \u00eencepe un pilot? Nu de la conectarea echipamentului \u00een raft, cu siguran\u021b\u0103 nu. \u00cenainte de a \u00eencepe orice lucru cu echipamentul, se lucreaz\u0103 la documente. \u0218i \u00eencepem cu definirea obiectivelor pilotului.
\nObiectivul pilotului este de a elimina obiec\u021biile din partea clientului final. F\u0103r\u0103 obiec\u021bii, pilotul nu este necesar. Da, da, exact a\u0219a.
\nDar care sunt principalele tipuri de obiec\u021bii pe care le putem \u00eent\u00e2lni?
\n* Ne \u00eendoim de fiabilitate
\n* Ne \u00eendoim de performan\u021b\u0103
\n* Ne \u00eendoim de scalabilitate
\n* Ne \u00eendoim de compatibilitate \u0219i capacitatea de a lucra cu sistemele noastre
\n* Nu credem \u00een sliderele voastre \u0219i vrem s\u0103 ne convingem, \u00een practic\u0103, c\u0103 sistemul vostru face toate acestea cu adev\u0103rat
\n* Toate acestea vor fi foarte complexe, inginerii no\u0219tri sunt deja supra\u00eenc\u0103rca\u021bi \u0219i le va fi greu<\/p>\n

A\u0219adar, \u00een cele din urm\u0103, ob\u021binem trei tipuri principale de testare pilot \u0219i, ca un caz particular al pilotului, dovada conceptului (PoC \u2013 proof of concept):
\n* Testare de \u00eenc\u0103rcare (+ scalabilitate)
\n* Testare func\u021bional\u0103
\n* Testarea rezisten\u021bei la erori<\/p>\n

\u00cen cazul concret, \u00een func\u021bie de \u00eendoielile clientului specific, \u00een pilot pot fi combinate diferite obiective sau, dimpotriv\u0103, poate fi prezent doar unul dintre ele. <\/p>\n

Pilotul \u00eencepe cu un document care descrie clar, \u00een limba rom\u00e2n\u0103, scopul acestui test. De asemenea, trebuie s\u0103 con\u021bin\u0103 un set de criterii m\u0103surabile care s\u0103 permit\u0103 o evaluare clar\u0103 a succesului pilotului sau identificarea aspectelor ne\u00eendeplinite. Criteriile m\u0103surabile pot fi numerice (de exemplu, laten\u021ba \u00een ms, IOPS) sau binare (da\/nu). Dac\u0103 \u00een pilotul dumneavoastr\u0103 exist\u0103 un criteriu care nu poate fi m\u0103surat, atunci pilotul nu are sens, fiind doar un instrument de manipulare.<\/p>\n

Echipament<\/h3>\n

Pilotul poate fi desf\u0103\u0219urat pe echipamente demo ale furnizorului\/distribuitorului\/partenerului sau pe echipamentele clientului. Strict vorbind, diferen\u021ba este minim\u0103, abordarea general\u0103 fiind aceea\u0219i.<\/p>\n

\u00centrebarea principal\u0103 privind echipamentele \u00eenainte de \u00eenceperea pilotului este dac\u0103 toate echipamentele necesare sunt prezente (inclusiv switch-uri, cabluri de transmisie, cabluri de alimentare)? Este echipamentul preg\u0103tit pentru testare (versiuni corecte ale firmware-ului, totul actualizat, toate semafoarele verzi)?<\/p>\n

Secven\u021ba corect\u0103 de ac\u021biuni dup\u0103 stabilirea obiectivelor test\u0103rii este o preg\u0103tire complet\u0103 a echipamentului pentru testare, \u00eenainte de predarea acestuia clientului. \u00centr-adev\u0103r, exist\u0103 clien\u021bi loiali care nu se gr\u0103besc, dar acesta este mai degrab\u0103 o excep\u021bie. Asta \u00eenseamn\u0103 c\u0103 \u00eentreaga echipare trebuie s\u0103 fie asamblat\u0103 pe site-ul partenerului, totul verificat \u0219i montat. \u00cen mod obligatoriu, sistemul trebuie s\u0103 fie pornit \u0219i trebuie s\u0103 v\u0103 asigura\u021bi c\u0103 totul func\u021bioneaz\u0103, software-ul se deschide f\u0103r\u0103 erori etc. Pare simplu, dar 3 din 4 pilo\u021bi \u00eencep cu c\u0103utarea cablurilor sau a transceverelor SFP.
\nEste important s\u0103 subliniem c\u0103, \u00een cadrul verific\u0103rii sistemului demo, trebuie s\u0103 v\u0103 asigura\u021bi de cur\u0103\u021benia acestuia. Toate datele din test\u0103rile anterioare trebuie eliminate din sistem \u00eenainte de predare. Nu este exclus ca testarea s\u0103 fi fost efectuat\u0103 pe date reale, unde pot exista informa\u021bii confiden\u021biale \u0219i date personale.<\/p>\n

Programul de testare<\/h3>\n

\u00cenainte de predarea echipamentului clientului, trebuie preg\u0103tit un program de testare care s\u0103 corespund\u0103 obiectivelor test\u0103rii. Fiecare test trebuie s\u0103 aib\u0103 un rezultat m\u0103surabil \u0219i criterii clare de succes.
\nProgramul de testare poate fi preg\u0103tit de furnizor, partener, client sau \u00eempreun\u0103 \u2013 dar cu siguran\u021b\u0103 \u00ceNAINTE de \u00eenceputul testelor. \u0218i \u00een mod obligatoriu, clientul trebuie s\u0103 semneze c\u0103 este mul\u021bumit de acest program.<\/p>\n

Oameni<\/h3>\n

\u00cen cadrul preg\u0103tirii pentru pilot, este necesar s\u0103 se stabileasc\u0103 datele de desf\u0103\u0219urare a pilotului \u0219i prezen\u021ba tuturor persoanelor necesare, precum \u0219i disponibilitatea lor pentru testare, at\u00e2t din partea furnizorului \/ partenerului, c\u00e2t \u0219i din partea clientului. O, c\u00e2te piloti au \u00eenceput cu plecarea principalului responsabil \u00een concediu cu o zi dup\u0103 instalarea echipamentului!<\/p>\n

Sfer\u0103 de responsabilitate \/ acces<\/h3>\n

\u00cen programul pilot trebuie s\u0103 fie clar definite \u0219i ideal descrise sferele de responsabilitate ale tuturor persoanelor implicate. Dac\u0103 este necesar, se va conveni accesul de la distan\u021b\u0103 sau fizic al inginerilor furnizorului \/ partenerului la sistemele \u0219i datele clientului cu serviciul de securitate al clientului.<\/p>\n

Pilot<\/h2>\n

Dac\u0103 am \u00eendeplinit toate punctele anterioare, cea mai plictisitoare parte este pilotul propriu-zis. Dar acesta trebuie s\u0103 decurg\u0103 f\u0103r\u0103 probleme. Dac\u0103 nu, \u00eenseamn\u0103 c\u0103 a existat o problem\u0103 \u00een preg\u0103tire.<\/p>\n

Finalizarea pilotului<\/h2>\n

La finalizarea pilotului se redacteaz\u0103 un document privind testarea efectuat\u0103. Ideal, cu toate testele din program av\u00e2nd bife verzi \u2013 FINALIZAT. Este posibil\u0103 preg\u0103tirea unei prezent\u0103ri pentru conducerea superioar\u0103 pentru a ob\u021bine o decizie favorabil\u0103 \u00een ceea ce prive\u0219te achizi\u021bia sau includerea \u00een lista sistemelor permise pentru achizi\u021bie.
\nDac\u0103 la finalul pilotului nu ave\u021bi un document cu lista testelor efectuate \u0219i marcajele de finalizare \u2013 pilotul a e\u0219uat \u0219i nu trebuia s\u0103 fie \u00eenceput deloc.
