Based on the collected data panagenda ApplicationInsights uses a wide range of criteria to determine design complexity and impact.
Factors that for instance can influence the complexity and impact are:

• Type and number of specific design elements occurring in the application design
• Specific combinations of design elements occurring in the application design
• Hardcoded references (for instance hard coded server names, etc.)
• Number of code blocks and code lines in the application
• Domino/Notes client dependencies
• Calls to local systems (for instance code that references a user's local hard disk or accesses specific files stored on the server)
• Occurrence of specific code elements that can cause potential migration/modernization challenges
• Occurrences of Author/Reader fields
• SMTP / mail / fax / etc. references that indicate a dependency on a specific system or server
• Third party software dependencies
• Encryption dependencies
• Mail dependencies
• Occurrences of specific code functions and snippets or combinations of such code functions and snippets.
• Etc. etc.
