R&DManager QA Manager

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

“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.”

Release

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

Together from the beginning!

Fully assimilated Scrum company Tester & coders

are fully integrated

!

Each night there is a build

Each sprint there is an handover

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

What is DONE?

• 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
