What do verification engineers

do?


Not really…


Verification activities

Contractual strategy

Influence architecture

Plan verification

Execute verification

Defend completion

VCD

A day in my past life…


Reqs

System Spec

Verif. Reqs

IVF

AIV flow

Schedule

Decision File

Test Spec

Support Docs System

My boss understood it!


And IT too!

Inconsistent information

Outdated information

Recurrent updates

Task repetition

Multiples sources of information Model on documents

Manual reproduction

Time demandingText to

substitute model

Manual propagation of changes

Loss of attention to open issues

Time demanding

Error prone

Lack of information linkage

Come on, show me how it is

used in real-life!


Thermal-Vacuum Test


Pre-environmental tests

Apply vacuum

Survival heating Apply thermal

control

Single HC Simple

functional Simulated

operation

Post-environmental tests

But this is a tiny part…

Look at integrated data, that’s

the THING!


Integration & Verification Flow



Integrated Spec-Plan-Procedure

Analyses are also needed


Why don’t simulate it?


Automatic current schedule


Who talks to who?


Automated WBS/WPD

Consistent WPD

Sensible WBS

Seamless Test Specification


But, do we get better?


Decision tracking

Automated activities improve

efficiency and effectiveness

Status reporting

Document generation

Integrated work

Information accessibility

What’s next?


Expand information model

Formalize integration into SysML

Measure effectiveness

Take away…


Mechanical engineering

Systems engineering

Pencil and paper MS Office

CAD MBSE

What can we learn?


Open for questions

Hold the tough ones…
