Traditional projects Budget? Credibility? Documents? Content? Quality? We will let you know Phone era Requirements Planning Development QA CA Release date: 30-Apr 2008 Budget? Credibility? Documents? Content? Quality? Release date: 3-Apr 2008 !!!! Release date: 27-Jun 2008 Release date: 10-May 2008 "Traditionalists often study what is taught, not what there is to create" -- Ed Parker

ואיך מרגישים האנשים הרלוונטים? Customer: Requirements Planning Development QA CA QA Manager: תיסכול היה אחלה, בוא ננסה עוד פעם! הסכמה תדהמה כעס The customer sees the product only at the end Definition of insanity R&D Manager QA "יש לך עוד, יש לך עוד, יש לך עוד...נו, תראה מה עשית!!!!"

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

What is Scrum? Topics of today “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.”

What is Scrum? Topics of today Changes will happen Team estimates “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 Development (QA & Code) Hardening Together from the beginning! 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

Sprint life cycle 15 minutes daily Stand up meetings 3 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

“Show me the money!” Review 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

Planning – Just before committing… TMQ / Premortum

Visibility Charts – Task Board Content Visibility! R&D R&D QA Coding Code Review Approval Each sticky note is a task Each task is up to 3 days Tasks are being moved by the team Create test script 5 Danko Explain the format of the sticky note Explain the format of the task board No surprise tasks Extra tasks with different color Emphasize the fact that the team members move the sticky notes Extra Task! The team is familiar with all the tasks No surprises

Visibility Charts – Burn Down Chart Progress Visibility! Remaining work 11 days Create test script 2 Team 1 Emphasize that the information comes from the team! Remaining work and not work that has been done Create HTML 3 Team 2 Create HTML 1 Team 3 Create HTML 5 Team 4 Committed tasks 4 tasks

Task Success Criteria Life cycle of a task Coder’s mind set: Construction Tester’s mind set: Destruction “You always pass failure on the way to success” -- Mickey Rooney

Role of the QA QA in Scrum 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

Start with the original KPIs Focus on your weakness 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

Scrum is being used for… Commercial software In-house development Contract development Fixed-price projects Financial applications ISO 9001-certified applications Embedded systems 24x7 systems with 99.999% uptime requirements the Joint Strike Fighter Video game development Satellite-control software Websites ISV applications Network switching applications Mobile phones
