Roles & Responsibilities QA Manager: A manager that needs to give the exact estimate for assuring the quality of the project suffer the postponements of the R&D manager but has the ability to release the product at the same deadline with the same quality while chasing the R&D manager for all changes that were not communicated R&D Manager: A manager that needs to give the exact estimate for developing the project While anticipating all impediments and future change requests Remember to update every relevant party and develop it according to the original estimate “The price of greatness is responsibility” -- Sir Winston Churchill

Topics of today What is Scrum? “SCRUM is a simple framework used to organize Teams, get work done more productively with higher quality, lot of team cohesion and commitment of the team.”
Topics of today What is Scrum? “SCRUM is a simple framework used to organize Teams, get work done more productively with higher quality, lot of team cohesion and commitment of the team.” • Changes will happen • Team estimates • Trust • Overall commitment • Visibility (Content & Progress) • Transparency • Frequent feedbacks • Inability to give accurate estimates • Fun!
Release Together from the beginning! Development (QA & Code) Hardening • Collection of sprints • Represents the entire products • Release is not a Gantt but only a rough uncommitted estimate • Commitment on the next immediate Sprint only
Commitment “While you are about to commit only to the iteration, …” “…it is imprudent to ignore the whole plan” “I've been on a diet for two weeks and all I've lost is two weeks” -- Totie Fields
3 Sprint life cycle A time-boxed period of time during which the Team works to turn the Product Backlog items it has selected into an increment of potentially shippable product functionality Self management team! 15 minutes daily Stand up meetings Sun Mon Tue Wed Thu Sun Mon Tue Wed Thu Sun Mon Tue Wed Thu “Yesterday…” I was late again 15 days “Today…” Sprint #4: Review meeting Retrospective meeting Sprint #5: Planning session Artifacts decision Sprint #3: Review meeting Retrospective meeting Sprint #4: Planning session Artifacts decision “Impediment…”
Fully assimilated Scrum company Tester & coders are fully integrated! Each sprint there is an handover Each night there is a build This slide is courtesy of Henrik Kniberg
Review “Show me the money!” • Time boxed (up to 1 hour max!) • Team demonstrates product increment • No PowerPoint please!!!!
Retrospective • Main challenge: Doing it • Doing it only at the end – Better not doing it at all • Remember only the last things • The “Bad” things • Forgetting the good things • Not implementing them • Do it every Sprint! • Immediate implementation

QA in Scrum Role of the QA • Getting potential shippable product every sprint • Part of the Delivery team • Estimate the tasks together with the R&D • Approve the tasks • Gaining full visibility on the build & product • QA is part of the definition “what is done” Who is he kidding? We’re ready to go! "If a man does his best, what else is there?" -- George Patton www.danko.org.il
What is DONE? Launch First Customer Launch Pilot Production Implementation User Acceptance Performance Testing System Testing Unit Testing Coding Design Analysis Planning
KPI – How SCRUM are we • Start with the original KPIs • Focus on your weakness • Measure it every sprint • Communicate it to the team • Consider adding: • Team Collaboration (QA & R&D) • Accomplishment (Is it really done) • Technical debts (How fast are we closing gaps) • How accurate are the estimates

אין פתרונות קסם! אבל יש פתרונות יצירתיים שממזערים את הנזק! • הבנה ששינויים רצויים, דרושים ותמיד יקרו • חלוקה לאיטרציות קטנות (שבועות ספורים) • הימנעות מדילמת השבויים • חלוקה למשימות קטנות (ימים ספורים) • המבצעים מעריכים • צוותים עצמאיים, מגובשים ומכווני משימות • האחריות עוברת לצוות • נראות מקסימלית "It is only by doing things others have not that one can advance." -- George Patton
