6. We want …
-… to improve quality in our products
-… more time for less obvious test
The QA team…
-… has low programming skills
-… is tired of executing repetitive tests
-… feels the pressure of time to market
What do we need?
-24h of automatic tests

7. Finding resources to implement it...
... without compromising the current roadmap…
... but keeping the knowhow inside
the company.
SUPPORT
MANAGEMENT
SUPPORT IS THE KEY
Add the project to the calendar.
Assign resources focused 100% on the implementation and convince your marketing fellows.
Try to keep it in-house.

8. FLEXIBILITY
Choosing suitable tools...
... with a tight budget…
... but the system has to be maintainable.
FLEXIBILITYIS THE KEY!
Don’t adapt the team to the tool, choose a tool accordingly to the skills of the ones who will use it ...
... use trial versions, open source applications...
... cheap tools can become expensive when trying to maintain the tests.

9. Stages
Stage 2: Tools Evaluation
-Search
-Compare
Stage 3: Kick off
-Automation of real test cases
-Model review
-Proof of concept
-Buy or download!
Stage 1: Definition
-Requirements
-Consider Maintainability

10. Stages
Stage 5: Transfer
-Transfer to QA team
-Pilot test using a real project
-Testers maintain the scripts
-SCM maintains the infrastructure
Stage 6: Maintainability & Monitoring
Stage 4: Infrastructure
-Software configuration
-Automatic launch
-Test Report generation
-Link with building process

11. Costvs Value

12. Implementingcontinuousintegrationmeans…
Interdepartmental teamwork
-Departments who participate in early stages of a project have to be committed
No need of big economical investment
-Use “FLEXIBILITY”: flexible tool and/or flexible team
Taking advantage of time and not wasting time
-Testing within continuous integration is agile
“Shelfware” fear will not materialise:
-maintainability is properly supported and planned
-implementation is SUPPORTED by other departments
