What Is Refactoring In SAFe®?
Refactoring
is a process of changing a software system’s structure with respect to its
external semantics while preserving its functionality. When we think about what
refactoring it is, there are three main objectives: to improve code quality, to
improve code readability, and to maintain or improve the system over time as
requirements change.
In the
agile environment where the requirements often change, refactoring is important
as they help in adding new features quickly without breaking the existing
features.
This
article will explore all about refactoring in SAFe®.
Definition - Refactoring
Refactoring
is a process of taking a code and changing its structure without changing its
behaviour. It helps the code to be well-designed, extendible, and maintainable.
Refactoring
in programming consists of two steps: improving the design and then ensuring
that the system still behaves in the same way as before. To make this process
more efficient, there are automated tools that can help us with it.
Refactoring
In SAFe®
Refactors can
accomplish things such as increasing processing speed, obtaining other internal
data or correcting security vulnerabilities. Another refactoring type is to
simplify certain aspects of a code to make it more efficient, readable, or
maintainable.

During the refactoring,
every change must be tested immediately to make sure that the desired goal is
achieved. The refractor can be divided into a series of successive micro refactors
to achieve a larger purpose; Each small refactor needs to be checked for correctness.
This iterative process maintains the integrity of the software at every stage.
SAFe® underlines
the significance of visibility of all work, including refactoring. Like user-centered
work, it needs to be planned, assessed, and prioritized at all solution levels.
How Does Refactoring Arise?

The refactors may be initiated by
a business function or it may be part of a larger refactoring initiative needed
by the entity the new architecture enabler. New user stories may also require a
code change. Due to the accumulated technical debt, the team may restructure
some components. New non-functional requirements (NFR) may need to be
redesigned.
Not all refactoring efforts are
based on the story. The Test-Driven Development (TDD) process encourages
continual redesign as code changes. Developers constantly update their projects
to better suit current and future needs. Such work should be considered when
assessing the story. However, some refactoring elements are larger parts of the
refactor that need to be planned and monitored as separate delay elements.
How Refactoring Demonstrate By The Team?
Refactoring focuses on internal
work, the team should demonstrate the following:
1.
Reduced processing times across multiple websites
compared to the previous standard.
2.
Processing time depends on the batch size that can
be configured from the file.
3.
Code snippet for asynchronous processing
4.
Debug log file that records all operations
5.
Number of dictionary queries per batch (from the ‘log’
file)
Conclusion
Refactoring
is one of the key techniques in agile development because it allows developers
to adjust the design as they implement it. It also prevents an accumulation of
bad designs that pile up into a large mess over time. This presents an
opportunity for project managers to tailor the development process according to
their needs, rather than following a set template blindly.
