Input-side: capture all changes

• Pros

  • Cost
    • often "free" byproduct of a CMS
    • small volumes

• Cons

  • Completeness/robustness
    • assumes all types of all content are perfectly managed by a change control process, hence inevitably incomplete
    • diversity of components needing management

  • Re-creation of website
    • requires re-creation of all hardware, software, content, data
