Applying Advanced Agile Methodologies

Our big challenge now is no longer the speed of code propagation. It’s how we can manage effective communication among streams

In the five years since I co-founded Bonitasoft with Miguel Valdes Faura and Rodrigue Le Gall, our organization has come a long way.

We started with seven developers. We now have 17 dedicated full time to Bonita BPM - along with a systems architect, a QA team, a documentation team, and a "human factors" engineer. We've logged 2.75 million downloads, booked 875 customers and built a community of 60,000 contributors.

How do you triple the size of your development team in less than five years and keep consistent control over your processes? Well, even for a company that's in the business of helping others improve processes, it's been a challenge, a learning experience - and a great opportunity to apply some interesting "advanced" agile methodologies.

How We Started with Agile
Our initial small team focused on development of the Bonita Execution Engine, the Bonita User Experience (web), and the Bonita Studio, with each of these groups having a specific skill set and a technical leader. From the very start we applied agile development practices - with everyone in the entire team working together in the same two-week sprint, participating in the daily scrum meetings, and so on.

With a small team, we were able to make very efficient progress all working on the same code - we got the first release of Bonita Open Solution out in six months.

But as we grew our development team and as we dealt with the inevitable errors that crept in, we found ourselves being held up. If the build chain broke, everyone's progress was affected.

With the growing team, to avoid these compilation issues, we broke up R&D into three individual teams (still focused on the Engine, the Web, and the Studio components of the Bonita BPM suite) and gave each team an independent release process for each component. This greatly helped us to isolate bug errors, but for fixes, the Studio team was always last in line - they needed a stable build from the Web team, who needed a stable build from the Engine team. It might take as long as two weeks before a bug-discovered-and-fixed on the same day by the Engine team actually propagated to the Studio team.

The Business Pressure to Change Our Development Approach
The growth of our team was only one aspect of the pressures we faced in engineering. As we moved through our Bonita Open Source version 5 product releases and began to prepare for the release of our new product, Bonita BPM version 6, we began to work more and more closely with the Product Committee. Together we started looking at ways to allow R&D to work on multiple features simultaneously, end-to-end, without pulling resources from one team to another. We wanted to reduce the time to fully develop new features of better quality, and to fix bugs. Bonitasoft's use of Value Streams at the strategic level offered a logical possibility: link R&D to corporate strategic goals for innovation and improvement.

The New R&D Organization: Agile Streams
Our development team is now organized into four streams: Innovation, Core Product, Integration, and Fast-Track. Strategically speaking, Innovation development keeps us at the leading edge of BPM suite capability, Core product development keeps us competitive in the current market, Integration remains one of our key differentiators, and Fast-Track helps ensure that users' needs are given appropriate priority.

The product committee's guidance heavily influences the priorities of the first three streams. The Fast-Track development priorities come from Support, Customer Success, Pre-Sales, and Delivery, the customer-facing groups inside Bonitasoft. In this way we continue to improve our product through both radical innovation and incremental improvements (new and improved features).

Each stream is comprised of Engine, Web, and Studio developers, plus a Product Manager and members of the documentation and Quality Assurance teams. Our systems architect and human factors engineer work across all four streams.

When a feature or improvement is developed in a stream, it is fully developed and tested on the stream's dedicated continuous integration server. A feature is "done" when the language translation is done, the documentation is done and the tests are done. When the entire code stream is stable, then and only then it is pushed to the shared continuous integration server where it can be accessed and used by the other streams.

When it is time for a major release, the code is pushed to another dedicated server where the final QA is done.

The advantages of this development approach are already being realized: the isolation of each stream and the involvement of QA inside each one means that the code is only shared when ready - and no other stream is dependent on work outside of it in order to advance.

It's also much cleaner to always have one stream dedicated to maintenance. We use a round robin approach so each stream has a turn, and only one stream is working on maintenance fixes at a time.

There's Always a Challenge
Our big challenge now is no longer the speed of code propagation. It's how we can manage effective communication among streams. Development may be appropriately isolated, but clear and timely communication on big changes is critical. We're addressing this challenge by sharing information frequently through informal presentations, and each team has a team leader whose responsibility includes sharing information across teams. Their entire mornings are pretty much dedicated to coordination tasks while their afternoons are dedicated to development tasks.

Looking Ahead
We are already seeing excellent results from our agile stream approach. Our maintenance releases are coming regularly each month, and the implementation of development roadmap is better balanced among the four strategic Value Streams. Bonita BPM has had two versions released in 2013, with two more on the way for 2014. With the Fast-track stream, we have been able to quickly respond to customers' and users' innovative suggestions and business needs - with a flexibility that underscores and confirms the very concept of agile.
