Inner Source in Platform-based Product Engineering

Abstract: Inner source is an approach to collaboration across intra-organizational boundaries for the creation of shared reusable assets. Prior project reports on inner source suggest improved code reuse and better knowledge sharing. Using a multiple-case case study research approach, we analyze the problems that three major software development organizations were facing in their platform-based product engineering efforts. We find that a root cause, the separation of product units as profit centers from a platform organization as a cost center, leads to delayed deliveries, increased defect rates, and redundant software components. All three organizations assume that inner source can help solve these problems. The article analyzes the expectations that these companies were having towards inner source and the problems they were experiencing or expecting in its adoption. Finally, the article presents our conclusions on how these organizations should adapt their existing engineering efforts.

Mike Milinkovich’s talk at OSS 2015 on “How the Eclipse Community Works”

TRENDS

  • Trend #1: Software über alles (ref: Software is eating the world)
  • Software is becoming the value-creating differentiator (impl: hardware is getting commoditized faster than software)
  • Trend #2: Quoting Immelt (GE): Every industrial company will become a software company
  • Milinkovich: Then, every company is becoming an open source company; also, software avg unit cost approaches zero
  • Many companies will not be able to pivot fast enough from license sales to new business models; they will fail

Favorite Story of Student Entrepreneur Ageism

I teach a course on software product management where I sometimes cross over into startup-land. During a recent class, I showed students a rara-talk by a VC, who was trying to convince them to become entrepreneurs. So I asked the class:

Statistically speaking, a 40-year old entrepreneur is much more likely to succeed than a student entrepreneur. Why is this venture capitalist so eager to get you to become an entrepreneur rather than a more experienced person?

After a bit of back and forth, one student finally said:

Well, if it takes 10 years to grow a startup, a 40 year old entrepreneur may not be be able to stick around for such a long time.

I’ve gotten used to such statements and take them rather stoically. A 40-year old PhD student of mine, however, was rolling on the floor laughing.
