Options

• BDifficulty migrating to new hardware
• CDifficulty training new admin personnel
• DDifficulty extracting data from the database

• A
  3% (1)
• B
  17% (5)
• C
  7% (2)
• D
  72% (21)

Explanation

A proprietary data format creates vendor lock-in. The greatest operational robustness concern is the inability to extract data from the database if the vendor discontinues the product, goes out of business, or if the application must be replaced. Without data portability, the entire manufacturing operation's historical and operational data could become inaccessible, making recovery or migration impossible. This is a business continuity risk of the highest severity. Options A (backup difficulty) and B (hardware migration) are real concerns but are secondary - if data can be extracted, backups and migrations become solvable problems. Option C (training personnel) is an operational concern but does not threaten the integrity or continuity of the data itself.
