Who is this presentation for?

  • Software architects, software developers, and project managers




Almost every software system is developed with good intentions but under difficult conditions. Deadlines, different qualifications, and misunderstandings in the development team lead to the architecture of the system eroding and technical debt is built up step by step, until the whole system is woven into a messy big knob and every adjustment becomes an incalculable cost screw. Neither the development team nor the management enjoy a system in such a state.

Carola Lilienthal explains how you can organize and further develop your source code to prevent the emergence and increase of technical debt. You’ll see which principles help to avoid technical debt and how they can be eliminated through appropriate refactoring. All of the recommendations are based on examples from the more than 300 analyses Carola has carried out on a wide variety of software systems. She also presents helpful tools.

Prerequisite knowledge

  • Experience programming and with large software systems (useful but not required)

What you'll learn

  • Understand what causes technical debt in software architecture, how to classify technical debt and how to recognize it, what to do to prevent technical debt, and how to get rid of technical debt if it's already there
