Technical Debt: Detection, Assessment and Strategic Debt

Technical debt: Recognizing, evaluating and strategically degrading

In the fast-paced world of software development time and resources are often scarce goods.

In order to comply with deadlines and bring new features to the market quickly, compromises in code quality are sometimes made. These compromises are known as technical debt.

But what exactly hides behind this concept. And how can companies learn to manage these debts not only. However, also strategically reduce them?

This article highlights the causes and effects of technical debt and shows practical strategies to successfully manage them.

What are technical debts?

The term "technical debt" was coined by software developer Ward Cunningham.

It describes the implicit costs arising from reworking on a software because one has opted for a simple but suboptimal solution instead of implementing a better but more complex solution.

You borrow time from the future by taking a shortcut today. However, this "yellow time".

Must later be repaid with interest, in the form of more elaborate maintenance and further development work.

A simple analogy is the construction of a house. One could initially dispense with a solid foundation to get ready faster.

The house is standing, but cracks and instabilities appear at the first major load.

The subsequent correction of these deficiencies is much more expensive and more complicated than to establish a stable foundation from the outset.

Technical debt can arise for different reasons. Often it is conscious decisions to achieve short-term goals. Sometimes they also arise unconsciously through lack of experience or inadequate processes.

The following table gives an overview of the most common causes:

Cause	Description
Time Print	Enge Deadlines force developer teams to fast solutions that are not always the most sustainable.
Long documentation	Unreasonable or outdated documentation makes the code understand more difficult and leads to errors in changes.
Fealing Tests	Unreachable Test Cover means that errors remain undetected and adhere to the code.
Old technologies The use of outdated technologies and libraries can make maintenance more difficult and risk security.
During experience	Unexperienced developers may tend to suboptimal solutions that lead to problems in the long term.
Unclear needs	If the needs for the software are unclear or contradictory, this can lead to incorrect code.
