Episode 20: Interview Michael Stal

Pattern Evolution

The evolution of software patterns has seen a shift from hype to mainstream adoption. Michael Stal notes that while the initial excitement promised a vast array of pattern encyclopedias, the reality is more subdued with fewer new publications emerging. However, the use of patterns in practical projects has become widespread, signaling their integration into everyday software development 1. Robert Blumen adds that the decline in pattern book sales reflects this mainstream status, as patterns are no longer a novelty but a standard part of the software engineering toolkit 2.

I think the only thing which is important about patterns, I think there are not many people know that. There are several pattern conferences, the blob, Euroblop, and other conferences, and we talked.

--- Michael Stal

The conversation also highlights ongoing efforts to catalog existing patterns, such as Grady Booch's ambitious project to compile a comprehensive architecture resource 1.

   

Knowledge Reuse

The discussion on knowledge reuse emphasizes the practicality of patterns over reusable software components. Michael Stal argues that reusing expertise through patterns is more adaptable and effective than relying on pre-built components, which often face limitations in specific domains 3. He shares his experience that while components like GUI grids are occasionally reused, the complexity of defining universal components for varied business needs often leads to failure 3.

You can just use an idea and the idea can be adapted to your own needs, so you don't have to either use the component or use nothing.

--- Michael Stal

Robert Blumen questions whether the reuse of software building blocks or knowledge is more effective, suggesting that patterns offer a more flexible approach to software development 4.
