As engineers, we like to solve problems by building solutions from scratch. Even though on some occasions it’s better to buy and integrate existing software. But how come? Are engineers who don’t always deliver from scratch real engineers? The goal of this talk is to answer all important questions about making build vs buy decisions. We’ll see how to define a clear strategy for making such decisions. And we’ll explore how to select and integrate existing software efficiently. Even if your company doesn’t have the habit of doing it.
