SitePoint.com: Software Development? We're Doing it Wrong.
Code reuse is largely accepted as "best practice" in our industry. Code reuse has many advantages, such as a smaller code-base which is easier to grok for developers. It's easier to maintain and optimize, since you can make less changes in order to achieve the desired results. Many modern techniques and tools were created in order to better reuse and modularize code. But while we're reusing code, we're duplicating effort. The same code is being written over and over in different places, wasting time and money.
He suggests that custom development should always be a last resort for software development, that there's plenty of other (open source) software out there that meets many of the needs businesses have. In his opinion, component-based development is the future of the industry - pieces that fit together with common interfaces and are larger than the sum of their parts. He sees a "commercial open source" model emerging from the current state of things. This model could result in more well maintained OS projects and more functionality being released as a part of it.
What we have currently is increasing noise, as more and more people have easier access to start programming and publishing their projects. We need to streamline the process and add that missing financial element that makes it sustainable and repeatable.
