What is Code Duplication? #
📉 Seeing high code duplication in your KPIs? Understand the risk, and how to fix it. 👉🏼 Read Blog
Duplicated code is one of the hidden pitfalls in software development and system customization. It’s difficult to detect and even harder to maintain. Worse still, it often leads to duplicated bugs, which can compromise stability, increase maintenance costs, and introduce unnecessary risk to your systems.
Code duplication directly affects the quality of your SaaS instances. In Quality Clouds, it is considered a key contributor to the overall Quality of Cloud (QoC) indicator. The more duplicated code detected in your environment, the lower your quality score, reflecting inefficiencies and higher chances of operational issues.
To help identify and address this problem, Quality Clouds automatically flags duplicated code blocks as issues during instance scans. These issues are tracked and categorized, providing visibility into where your code base could be streamlined and improved.
Why this matters #
Code duplication increases maintenance effort, risk, and inconsistency across your codebase. A single change may need to be replicated in multiple places, increasing the likelihood of errors and missed updates.
Over time, this leads to higher technical debt, reduced code quality, and greater operational risk. It also slows down development, as teams spend more time managing redundant logic instead of delivering value.
By identifying and reducing duplication, organizations can:
- Improve maintainability and simplify code changes
- Reduce bugs and inconsistencies across the system
- Lower technical debt and improve QoC scores
- Increase development efficiency and scalability
Code Duplication View in Salesforce and ServiceNow
#
To make this analysis even more accessible, Quality Clouds now provides a dedicated dashboard for code duplication across Salesforce and ServiceNow.
This dashboard offers a visual, centralized way to track, assess, and act on duplication issues. It simplifies the identification of recurring patterns and helps teams prioritize remediation work efficiently.
Code Duplication Best Practices
#
Our platform currently includes specific best practices to detect code duplication in the following SaaS environments:
Salesforce
We analyze Apex classes, triggers, Lightning components, and other metadata for repeated logic. This allows you to identify unnecessary duplication and improve performance, scalability, and maintainability. Code Duplication in Salesforce
Microsoft 365 (O365)
In custom scripts and automation rules, our engine scans for repeated logic and structural patterns that may compromise long-term efficiency and clarity. Code Duplication in O365
