This article 👇 offers an introduction to #MoldableDevelopment.

It's written for a first time reader. It's not quite short, but it's not that long either (~4000 words). It has concrete examples, but also a little broader theory.

It starts from the reading problem: reading accounts for the single largest expense in software development today, but it's just a strategy to gather information from the system. We can automate much of it, but we should do it through custom tools.

To give a hint as to why this is relevant, I describe of an experiment in which we gave student teams the same requirements and a constrained tech. They produced very different structures which suggests that a system's inside emerges over time and that we need to react to it.

3/

I then describe a public exercise in which we explored the use of system properties and feature toggles in Open edX. Automating the detections necessarily required a custom solution that matched the internal framework used for defining these properties.

Even more interesting was how once we had an overview of the definitions and usages of properties, we could also identify dependencies that would otherwise remain hidden.

This is just an example, but it shows what building custom tools could mean. For this proposition to be practical, the construction of custom tools must be inexpensive. We develop #GToolkit to show how #MoldableDevelopment can work in practice.

#GToolkit is not only an enabling technology, it is also an elaborate case study of #MoldableDevelopment. To exemplify this idea, I show a couple of scenarios in which we use the environment to document and reason about the environment itself.

The technology is important, but the key resides in the method of working. This implies new skills (and roles) and new opportunities for working as a team.

9/

By decreasing the cost of insights about the system, #MoldableDevelopment introduces a new feedback loop that has far reaching consequences also for the business.

Working with @BenLinders on this article was just extraordinary.

I hit a writer's block at the beginning of the year, but Ben kept pushing diligently for 8 months! Along the way he helped me refine the article to make it more digestible for first readers.

Thank you Ben!
