Perchè Lean nell’IT?
Per migliorare il nostro lavoro..
Perchè ?!?!? dovremo?
Forse si, perchè..…
Cosa si utilizza oggi per
     migliorare?
CMMi
Ma i nostri clienti hanno meno
 problemi grazie a questi?
No !
…..Perchè ?.....
Diamoci un’occhiata..
Un’occhiata da vicino….
All’inizio, c’è un cliente…
….il cliente, ha qualche….
Necessità !
Che viene trasformata in..
Specifiche
Il cliente controlla le
       specifiche
Il cliente
evidenzia le
sue necessità
Noi riscriviamo le specifiche
Così, solo allora, si passerà a.…
Allo sviluppo
Si ricontrolla insieme al cliente
Il cliente ha cambiato
qualche dettaglio…
(Intanto è passato del tempo
  dalla specifica delle prime
          necessità)
Nuovamente a sviluppare
(Oppure era un problema di
       specifiche?)
Con un po di fortuna dovremo
 essere in grado di iniziare…
… a testare…
Ma solo allora…
Troviamo i bugs
Nuovamente a sviluppare..
Ancora tests…
Finalemente è arrivato il
giorno che riusciremo a
      passare in…
Pre-produzione
E’ arrivata l’ora…
… per un terzo controllo con il
           cliente
I Bugs si trovano con i dati
            reali…
Nuovamente a sviluppare…
Sono stati trovati anche dei
      bugs funzionali
Nuovamente a scrivere
     specifiche
Poi a sviluppare…
Fare altri test..
E nuovamente in pre-produzione
Ed alla
   fine, dovremmo
riuscire ad andare..
In produzione..
Siiii!
Ma poi, ci sono…
Gli incidenti di produzione!
Che sappiamo come risolvere
           …
  (Scegli il modo migliore)
 Rinizia il lavoro..
 Rinizia il lavoro
 Aggiungi spazio disco
 Rinizia il lavoro
 Aggiungi spazio disco
 Aggiungi CPU
 Rinizia il lavoro
 Aggiungi disco
 Aggiungi CPU
 Aggiungi…….
Soltanto allora…
(Il prodotto viene riconsegnato)
New incident!
Adesso è arrivata l’ora di.…
Dell’analisi dei problemi…
Che ci permetteranno di trovare…
La Buona soluzione !
(Nuovamente a sviluppare…)
(test)
(pre-produzione)
(in produzione)
Mentre il cliente aspetta ancora…
Finalmente realizziamo che…
E’ arrivata l’ora di…
The task force!
Bisogna analizzare ancora qualche
           problema…
(nuovamente a sviluppare)
(tests)
(pre-produzione)
(in produzione)
……..
Déjà vu?
Nulla di strano se…..
Specification teams
Sviluppatori
Test teams
I team di pre-produzione
I team di produzione
I team di gestione degli
       incidenti
I team di problem management
… sono sovraccarichi   !
…
La soluzione
 è…..Lean!
