Agile Tour 2009
Last week I attented the Grenoble (October 20, 2009) and Valence (October 22, 2009) conferences as part of the Agile Tour 2009 series. These events were a big success and attracted more than 450 attendees! I would like to thank one more time the CARA who did a very good job at organizing these.
The presentations were of very high quality and their diversity pleased practionners as well as managers and students. All the slides are accessible on the CARA’s website (French and English).
I gave a talk in Grenoble and Valence about the infrastructure and processes we put in place at AdaCore to build and test on a daily basis all our compilation chains and accompanying technology in a Lean fashion.
I also presented the “qualification machine” we have built based on open source technology to ease the DO-178B tool qualification process by adopting an agile philosophy.

Is it finally time for Lean and Agile Certification?
The problems encountered within the AirBus 400M program highlight the importance of deploying an effective infrastructure when developing high-integrity systems. The core of DO-178 is indeed really about:
So far, I’ve seen two major experiments to support lean and agile DO-178 certification/qualification. The first is through the use of complete tools such as OSEE. OSEE is able to track each user activity along with the artifacts it involves: it is “basically” an Application Lifecycle Management System integrated with an Action Tracking System, an Automated Testing Framework, a Requirement Management System and advanced Version Control System. Evidence of the quality of artifacts and of their mutual relations is provided by checking that appropriate verification activities have been performed; on the other side, evidence that a given plan has been followed is provided by analyzing the flow of tracked actions against a user-defined workflow. OSEE has been extensively used at Boeing for the Apache Program.
An alternative approach can be applied for more lightweight processes, for example the qualification of a verification tool. We have been using an hacked version of FitNesse (a web-based tool for acceptance testing) to support:
Applying lean and agile methodologies to DO-178 certification/qualification requires investing on tools – but the reward is well worth the cost. What is your experience with this? Which tools do you use? Comments are welcome!
- the quality of artifacts (how good is a requirement/algorithm/test/etc.?)
- the quality of relations between artifacts (can I justify the existence of an artifact by tracing it to other artifacts?)
- the evidence a well-defined process has been followed (was I faithful to my plan?)

- editing of qualification documentation (Tool Qualification Plan, Quality Assurance Plan, etc.);
- tracking of verification and quality assurance activities when needed.

Lean, Agile Approach to High-Integrity Software
The “Lean, Agile Approach to High-Integrity Software” event took place on March 26 at the Maison de la Chimie in Paris. In all, over 80 people joined us for a day dedicated to looking at ways in which Lean and Agile methods can (and are!) being used to develop software that requires certification – a very heavy process as many of you will know. The videos and slides from the workshop will be posted at a rate of 1 per week starting next week. Thanks to everyone that participated and made the day so valuable!
