As a subsidiary of the European leader in access to space, ArianeGroup, Sodern core business is the series production of star trackers that enable satellites to orient themselves precisely in space, and neutron systems for analysing and detecting materials.

What is interesting in Tuleap, is its Open Source aspect. This is crucial for us. We did not want to be vendor or technology locked-in. An Open Source tool dramatically reduces this risk. This is the most sustainable solution.

  • All project stakeholders can access project schedules and collaborative workspace.

Their industry challenge

The importance of Quality in the Aviation, Space and Defense industry

Called a “key actor” of national defense by French minister Jean-Yves Le Drian, Sodern develops and produces the neutron sources for the French nuclear force, part of the payloads of the French military satellites dedicated to Earth observation , GPS-free positioning systems, etc. Sodern’ activities cover several ranges of space instruments (instruments for satellite attitude control, instruments for Earth observation, unique scientific instruments created on demand and integrated aboard satellites, space stations and space vehicle) as well as Stars Trackers.

Quality is paramount to companies in the aviation, space and defense industries. A company as Sodern in the newly emerging space market has to rely on a quality ALM solution to deliver robust products and applications.

The importance of Sustainability & Open Source

Due to the unique nature of Sodern’s business, the company cannot afford to become dependent on any software vendor or technology.

Some of the applications we develop ends up on satellites for missions that can last two decades. Our development and maintenance timeline can be 25 years or more. For us, a license tying us to a particular vendor exposes us to an unacceptable risk — that the vendor will go out of business and the source code will disappear.

Pierre-Yves Bretecher, Head of Electronics and Software Engineering Department, Sodern

It is important to notice that the ability to see the source code of a tool is not the same as the ability to modify a deployed software in production. This is possible only with an Open Source licence, not with a propriety tool, not with an open core tool.

What they did

Sodern had built up three years of data in its former ALM tool. Migrating the data to Tuleap was crucial. It had to be fast and easy.
“With the Tuleap team, I think we spent a total of one day assessing the situation, and another two days installing and configuring Tuleap.” explains Pierre-Yves. “That alone is impressive!”

Sodern’s developers particularly appreciate Tuleap’s powerful tracking feature.

Their results 

Tuleap Tracking feature? There’s nothing else more powerful!

As Tuleap is designed for use by both developers and project managers who don’t necessarily have advanced software development knowledge, Tuleap gives them a comprehensive overview of project status and let them adjust priorities and complete other tasks.

Sodern teams can now track tasks, bugs, and change requests—plus everything is automatically cross-referenced for virtually exhaustive links. Developers can also access the full range of Tuleap’s particularly agile features right from the Eclipse development environment. No more back-and-forth between the two interfaces.

Another thing we like, is that Tuleap can be used for projects other than software, such as systems modeling and ASIC and FPGA design projects. This lets us work on all of our equipment’s components from a single interface.
