Model-Minded Development

Explore the concept of Model-Minded Development in this 39-minute conference talk from GOTO London 2016. Delve into the importance of models in software development, comparing short-term and long-term approaches in both companies and programming. Discover how theory building in science relates to programming, and learn about the breakthrough in Domain-Driven Design. Examine practical examples like understanding addition, long division, and the von Neumann architecture to illustrate the significance of internal-external model alignment. Gain insights into how developers weave models into programs, the types of models visible in code, and the distinction between reusable and ad hoc models. Conclude with valuable lessons on steering both ships and development teams using model-minded approaches.

What is Model Minded Development?
Do we really need models?
Companies: short and long-term
Software development: short and long-term
Example behavior with/without models
Why model? Need good arguments.
