Software designers, not engineers: An interview from alternative universe

While the physicists investigate the nature of the mysterious portal that has recently appeared in North London, several human beings recently came through the portal, which appears to be a gate into an alternative universe. As we understood from the last two people coming through the portal, it seems to be a linked with a universe that is in many ways like ours, reached about the same level of social and technological development, but differs in numerous curious details. The paths through which people in this alternative universe reached similar results as our world are often subtly different.

The most recent visitor from the alternative universe is Ms Zaha Atkinson, who would most likely be titled software engineer in our world, although the title she uses in her home world is software designer. She is a well-known software designer and has been also titled using the strange-sounding title softwarenova, a label that we will soon say more about. As with other technological and societal developments, the alternative universe seems to have arrived at very similar results as our worlds. Software is eating the (alternative) world, but it is built in very different ways. The interview with Ms Zaha Atkinson, presented below, reveals how very different the world of software is when we think of programmers as software designers rather than as software engineers.

This article is a work of fiction. Any resemblance to actual events or persons, living or dead, may or may not be entirely coincidental. It has been largely inspired by the book Designerly Ways of Knowing by Nigel Cross. Ms Zaha Atkinson also may or may not be entirely fictional.

On architecture, urban planning and software construction

Despite having the term science in its name, it is not always clear what kind of discipline computer science actually is. Research on programming is sometimes like science, sometimes like mathematics, sometimes like engineering, sometimes like design and sometimes like art. It also has a long tradition of importing ideas from a wide range of other disciplines.

In this article, I will look at ideas from architecture and urban planning. Architecture has already been an inspiration for design patterns, although some would say that we did quite poor job and imported a trivialized (and not very useful) version of the idea. However, there are many other interesting ideas in architecture and urban planning worth exploring.

To explain why learning from architecture and urban planning is a good idea, I will first discuss similarities between problems solved by architects or urban planners and programmers. I will then look at a number of concrete ideas that we can learn, mostly taking inspiration from four books that I've read recently. There are two general areas:

The nature of problems that programmers face are often more similar to the problems that architects and urban planners have to deal with than, say, the problems that scientists, engineers or mathematicians need to solve. We might not want to go all the way and completely rebuild how we do programming to mirror architecture and urban planning, but treating the ideas from those disciplines as equal to those from science or engineering will make programming richer and more productive discipline.

The design side of programming language design

The word "design" is often used when talking about programming languages. In fact, it even made it into the name of one of the most prestigious academic programming conferences, Programming Language Design and Implementation (PLDI). Yet, it is almost impossible to come across a paper about programming languages that uses design methods to study its subject. We intuitively feel that "design" is an important aspect of programming languages, but we never found a way to talk about it and instead treat programming languages as mathematical puzzles or as engineering problems.

This is a shame. Applying design thinking, in the sense used in applied arts, can let us talk about, explore and answer important questions about programming languages that are ignored when we limit ourselves to mathematical or engineering methods. I think the programming language community is, perhaps unconsciously, aware of this - one of the reviews of my recent PLDI paper said "this is a nice, novel design paper, and the community often wants more design papers in our conferences". The problem is that we we do not know how to write and evaluate work that follows design methodology.

To better understand how design works, I recently read The Philosophy of Design by Glenn Parsons. The book perhaps did not answer many of my questions about design, but it did give me a number of ideas about what design is, what questions it can explore and how those could be relevant for the study of programming languages...
