8 GIVEN WHEN THEN - ett exempel

9 The new service

10 Service X User story: - AS A - I WANT - SO THAT - GIVEN - WHEN - THEN - GIVEN - WHEN - THEN User story: - AS A - I WANT - SO THAT - GIVEN - WHEN -THEN

11 Service X AS A customer I WANT TO search for an e-invoice invoicer/creditor/company SO THAT I can sign up for e-invoice AS A customer I WANT TO sign up for e-invoices with my chosen companies SO THAT I don t have to pay the invoices manually AS A customer I WANT TO cancel an e-invoice agreement AS A customer I WANT TO view my e-invoice agreements SO THAT I know which ones I have AS A customer I WANT TO edit one of my e-invoice agreements SO THAT it s kept up to date with my current situation and my current wishes AS A customer I WANT TO view my upcoming e-invoices SO THAT I know which ones I need to approve AS A customer I WANT TO view my completed e-invoice payments SO THAT I can follow up on my transactions AS A customer I WANT TO cancel an upcoming e-invoice payment SO THAT the amount won t be withdrawn

12 Service X GIVEN xxx WHEN the customer performs an e-invoice search by giving the company name THEN an e-invoice search is performed GIVEN an e-invoice search is performed WHEN one or more matching results are found THEN the matching result(s) are presented in a list containing the following information: Company name, xxx, xxx AS A customer I WANT TO search for a e-invoice company SO THAT I can sign up for e-invoice GIVEN an e-invoice search is performed WHEN no matching results are found THEN xxx GIVEN an e-invoice search result is presented in a list WHEN the customer filters by choosing sector code(s)???

AND the status of the e-invoice agreement is set to xxx GIVEN xxx WHEN the customer requests to read the terms and conditions for the e-invoice THEN the terms and conditions are presented as/in xxx

13 Scenario exempel - acceptanskriterie Hur vet vi att vi är klara med storyn?? När storyn är i produktion, hur vet vi att vi lyckats? Vad ska bli skillnaden? GIVEN som en förutsättning- passivt WHEN beteendet (vad ska systemet göra?) - aktivt THEN resultatet, vad är sant efteråt? - passivt GIVEN the trouble ticket has status Confirmed WHEN the operator requests to send the order THEN the trouble ticket status is set to Sent AND the order is placed in the queue to be sent

14 User story 1 Specificeras genom * Scenario User story VEM vill något, VAD vill denne och VARFÖR Får vara lite fluffig BEHOV eller PROBLEM Scenario, acceptanskriterie, exempel Explicit, otvetydig Är storyn testbar? Vilka förutsättningar ska vara sanna för att lösa problemet? Vilket är det förväntade beteendet? GIVEN/WHEN/THEN Prototyp etc

AS AN operator I WANT the Reporter to receive an notification whenever there s an update in the trouble ticket he reported SO THAT he can keep himself informed and we can save time since he won t have to call us and ask Vart ska den skickas? Epostadressen måste finnas registrerad eller? När ska den skickas? Direkt? Vilka förändringar är det som triggar att epostmeddelandet ska skickas? Alla statusförändringar eller bara en del? Ska det lagras och visas någonstans att meddelandet skickats? Vad exakt ska meddelandet innehålla? Kan vi göra ett exempel? Hur ska det se ut? Layout? Vad kan gå fel? Etc etc
