It was known long ago…
«To avoid disaster, all the teams working on a project should
remain in contact with each other in as many ways as possible — e-mail, phone, meetings, memos
etc.»
1975 – 1982 - 1995

The solution?
Project team builds
Testing team knows the
status
= requirementsThe customer
knows acceptance criteria
Project sponsor knows business
risks

Status-showing bulb panel O
ne bulb for each requirement
From the beginning, all lamps shine red: no requirement has been implemented,
nothing has been verified
6victo.eu 2013
Not all bulbs are the same
• Small lamps: less important requirements (lower business risk, lower risk consequences)
• Big lamps: higher business risks
7victo.eu 2013
Risk probability
Lamps on high posts
denote high probability
risks
8victo.eu 2013
Evaluation significance
Brighter lamps mean higher status significance (e.g. more thorough testing,
higher test coverage needed)

Bulb matrix and test design
• It makes basic (risk-based) test design decisions more visible, but does not solve them• How much will given test cases
decrease probability?• With what significance?
11victo.eu 2013
Bulb matrix and test execution
• Test execution order and prioritization• Release planning• Traditional test reporting hardly
needed any longer• Status visibility on all levels
12victo.eu 2013
… and test completion criteria
• Test process gains emotional intelligence no more «are we ready?» questions• Automatically to all levels• Business criteria already build
into requirement importance
13victo.eu 2013
Benefits until now
• Risk-based testing de-mystified• … connected to model-based
testing• … and requirements engineering• … and risk management• IT’S MUCH SIMPLER!

More benefits
• Project management:•Requirements → project tasks•Requirements implementation → project estimation•Requirements status → project monitoring
• Data for process improvement

worth considering for pilot project:–You pay for what you use–Scalable
