Technical debt: A guide for refactoring & Reengineering

Short: In software development, the term "Technical Debt" is ubiquitous.

In software development, the term "Technical Debt" is ubiquitous.

It describes the implicit costs of a suboptimal technical solution, which, while allowing rapid implementation in the short term, leads to considerable maintenance and development problems in the long term.

As with financial debt, "interests" are included here – in the form of slowed development, increased susceptibility to errors and rising costs.

In this guide we will show you how to systematically reduce technical debt using the methods Refactoring and Reengineering.

What are technical debts?

Technical debts arise when developers consciously or unconsciously compromise code quality to achieve short-term goals. The causes for this are manifold:

• Time pressure: A short release date forces to fast but "unclean" solutions.

• **The team does not yet know the best solution at the time of development.

• Fealing tests: Unreasonable test coverage leads to incorrect code remaining undetected.

**Old technology:**The technology used is no longer modern and impedes modern development practices.

"Technical debts are like a loan you take up to advance faster.

If you don't pay it back, interest – the additional effort for future changes – will always be higher." Martin Fowler

The consequences: Why not ignore technical debt

Short: Executive answer: Technical debts can slow down further development.

Untreated technical debt can have serious consequences:

• Sustainable development: Any new function or modification will be more complicated as the existing code is difficult to understand and adapt.

• ** Increased error rate:** Complex and unstructured code is a frequent source of error.

• Demotivation in the team: Developers are frustrated when they are constantly fighting against a bad code base.

• Innovation store: Resources are committed to troubleshooting and circumventing problems instead of developing new value-creating features.

Strategies for Degrading: Refactoring and Reengineering

Short: In order to reduce technical debt, there are two central but different profound methods: refactoring and reengineering.

Refactoring: The continuous improvement

Short: Refactoring is the process to improve the internal structure of code without changing its external behavior.

Refactoring is the process to improve the internal structure of code without changing its external behavior.

It is a continuous, small-part measure that is ideally an integral part of the daily development process.

A. Description

** Objective * * Improving legibility, comprehensibility and wartability of the code. Reducing complexity.

**Shipping * * Small and focused. Change
