Hotspot

As explained in Architecture Modernization: Socio-technical alignment of software, strategy, and structure

A hotspot is an area of a software system that is both highly complex and changed frequently.

A hotspot is an area of a software system that is both highly complex and changed frequently. These areas are strong candidates for prioritizing modernization, but they should not determine major decisions alone. section 12.4.3

Finding hotspots with CodeScene

CodeScene combines code-health analysis with version-control history to identify areas that change often and have high complexity. It can reveal dependencies, defects, complexity trends, source code, and increasingly granular function-level views. section 12.4.3

Use hotspot analysis as one input to modernization discovery:

• Inspect dependencies, defects, and complexity trends around a candidate area. section 12.4.3
• Combine tool findings with code reviews, workshops, current-state mapping, and engineer knowledge. section 12.4.3

Visual code-health views help locate candidate hotspots before examining their detailed dependencies, defects, and complexity trends. section 12.4.3

How Architecture Modernization: Socio-technical alignment of software, strategy, and structure covers it

How deep it goes

Defines hotspot detection through complexity and change frequency, but stops short of endorsing tool-only modernization decisions.

Examples

Shows CodeScene visualizations, dependency details, defects, complexity trends, and function-level analysis.

What it assumes

Assumes access to version-control history and engineers who can assess the system beyond automated findings.

What you can do after

Diagnose modernization candidates with tool analysis, then validate them through engineer feedback and collaborative assessment.

How it connects

Links hotspots to code health, version control history, change coupling, and modernization.
