Team Sprint planning meeting capacity Sprint prioritization Product • Analyze and evaluate product Sprint backlog backlog goal • Select sprint goal Business conditions Sprint planning • Decide how to achieve sprint goal (design) Current Sprint product • Create sprint backlog (tasks) from product backlog items (user backlog stories / features) Technology • Estimate sprint backlog in hours28
  • 29. Sprint planning • Team selects items from the product backlog they can commit to completing • Sprint backlog is created • Tasks are identified and each is estimated (1-16 hours) • Collaboratively, not done alone by the ScrumMaster • High-level design is considered As a vacation Code the middle tier (8 hours) planner, I want to Code the user interface (4) Write test fixtures (4) see photos of the Code the foo class (6) hotels.

  • 41. Definition of Done From a presentation by Ken Schwaber: 1. I can readily understand the software and where and how things happen; 2. When I change or add to part of the software, there are no unintended or poorly designed dependencies; 3. I can read the code without lookin for tricks or poorly defined and • labeled variables or is een taak (een stuk code) af? Wanneer data; 4. I don’t need the person(s) who wrote the code to explain it to me; 5. There are a full set of (automated) tests to check that the function works as expected; 6. When I change something and add to the test, I can check that the entire change and product continuous to work; 7. How thing work and hang together is transparent, and 8. Standard, well-known design principles have been adhered to.41
  • 42. Definition of Done • Ten behoeve van de test wordt een voorstel voor een testaanpak opgeleverd. • Een oplevering moet volledig zijn getest (door middel van een functionele en een regressietest) en de testresultaten moeten zijn beschreven / bevindingen zijn geregistreerd in een testrapport. • Issues worden geregistreerd zoals beschreven in bijlage 1. Een oplevering mag per ernstcategorie niet meer dan het aantal bij de betreffende categorie vermeldde maximum toegestane open bevindingen bevatten. • 80% van alle pagina’s moet binnen 2 seconden volledig zichtbaar zijn, de overige pagina’s moeten binnen 5 seconden zichtbaar zijn. • Rapporten en overzichten welke dagelijks kunnen worden opgevraagd door teamleiders moeten binnen 15 seconden in beeld verschijnen, voor de overige rapporten is geen performance eis gesteld. • Er moeten meerdere mensen tegelijk kunnen raadplegen en muteren. • Coding guidelines van Microsoft worden gehanteerd. • Per oplevering wordt een installatiehandleiding met release notes meegeleverd waarin o.a. het datamodel en de samenhang van de technische modules staan vermeld. Daarnaast wordt een set met User Stories die in de betreffende oplevering zitten meegeleverd. • Elke oplevering moet op zowel de acceptatie- als productieomgeving geïnstalleerd kunnen worden, wat betekent dat iedere oplevering na de eerste oplevering een upgrade moet zijn in plaats van een full install. Deze moet voldoen aan de eisen van de beheerorganisatie van <klant>. • Helpteksten dienen in de applicatie te staan om zodoende een gebruikershandleiding overbodig te maken, maar het is niet vereist dat deze ook middels een beheerscherm in de applicatie beheerd kunnen worden. • Voor elke oplevering wordt er een architectuurcontrole uitgevoerd waaruit blijkt dat men zich gehouden aan de voorgeschreven architectuur. • Voor elke oplevering wordt een installatie-test uitgevoerd waaruit blijkt dat de software succesvol installeerbaar op de infrastructuur zoals in gebruik bij <klant>42
  • 43. Definition of Done • Tested & bugfree • Refactoring • Deployed to test server, • Code reviewed when so PO can test needed • All user actions • Remember to check • All supported browsers the Style_guideline • IE7/8 • Maintain wiki page • Chrome • Maintain ERD document • Firefox • Versions of components • Safari on Mac • License overview • Comments in code • Check the constraints43
