WRONG QUESTION !!!
22
Where can I get quality?
Quality has to be built in inside the product during development:
quality has to become an organizational goal: quality policy customer oriented organizations
quality has to be planned (PDCA cycle): strategies (plans) for quality assurance measures are created:
plans for Testing, for Reviews, for Audits etc.
“quality has to be caused and not controlled”
23
Quality does not depend on the tool, it depends on you.
Where can I get quality?

PDCA
25
PDCA for… kitchen.
26
PDCA for … testing. define testing strategy (what, when, who, how):
what: establish what you test against module/integration/validation testing define coverage targets, other targets (budget, timing)
when: correlate the need with the release content, start early enough
who: nominate which person tests what how: choose the correct testing methods to derive the
tests, implement traceability towards requirements create planning (tasks, deadlines, responsibles, agree
planning with other stakeholders)
27
set-up test environment as required
develop testcases according to defined strategy
run testcases by taking into consideration: defined targets test environment
PDCA for … testing.
28
check if targets were achieved: coverage targets (e.g. requirements coverage,
automation degree etc.) timing, budget deviations
PDCA for … testing.
29
if targets are not achieved, react: more man power additional equipments escalate to next level of management
PDCA for … testing.
