Hype Driven Development (HDD) is an ironic term in software development that refers to the tendency to adopt technologies or practices because they are currently trendy, rather than selecting them based on their actual suitability for the project. Developers or companies practicing HDD often embrace new frameworks, tools, or programming languages because they are gaining a lot of attention, without sufficiently analyzing whether these solutions are truly the best fit for their specific needs.

Typical characteristics of HDD include:

• Short Hype Cycles: New technologies are adopted quickly, often without proper testing or understanding. Once the hype fades, the technology is often discarded.
• FOMO (Fear of Missing Out): Developers or teams fear being left behind if they don't keep up with the latest trends.
• Unclear Benefits: New technologies are introduced without clear understanding of which problems they solve better than tried-and-true approaches.

Overall, Hype Driven Development often leads to overcomplicated architectures, technical debt, and a significant investment of time in learning constantly changing technologies.
