Data Integrity and Validation in Schedule Archiving

Correct Answer: Verify schedule baseline alignment with approved change requests

Verifying schedule baseline alignment with approved change requests is the most critical validation check for archiving schedule data. This ensures that all documented changes have been properly incorporated into the schedule before archiving. This validation preserves the integrity of the schedule data by confirming that all formal modifications have been properly recorded and implemented. It maintains a clear audit trail and ensures compliance with change control procedures. The other options are less suitable because: Analyzing resource availability patterns and historical trends is more relevant for future planning than data archival integrity. Reviewing schedule constraints against software standards focuses on technical aspects rather than the actual content integrity of the schedule data. Comparing progress metrics with benchmarks relates to performance measurement rather than validating the accuracy of archived schedule data.

Correct Answer: Implementing version control with digital signatures and timestamps on each baseline

When implementing a schedule archiving system, version control with digital signatures and timestamps is the most effective technique for ensuring data consistency across multiple schedule versions. This approach provides: 1. Authenticity verification through digital signatures 2. Precise chronological tracking via timestamps 3. Clear baseline establishment for each version 4. Tamper-evident documentation of changes 5. Ability to trace modifications back to specific users and times The other options are less effective because: - Running automated consistency checks is reactive rather than proactive and may not prevent inconsistencies - Parallel backup systems focus more on data redundancy than version consistency - Incremental backups with cross-referencing may miss important metadata and don't provide the same level of authentication as digital signatures

Correct Answer: Implementing version control with sequential identifiers for archived schedules

Implementing version control with sequential identifiers for archived schedules is the best practice for maintaining data integrity because: - It ensures clear tracking of schedule versions over time - Prevents accidental overwriting of previous versions - Makes it easy to identify and retrieve specific schedule versions - Enables audit trails and historical analysis - Supports compliance and governance requirements Other options are less effective: Storing files in a centralized location addresses accessibility but not version integrity. Converting to read-only formats focuses on security but limits necessary schedule updates and modifications. Maintaining a change log is important but secondary to proper version control - it documents what changed but doesn't inherently protect file integrity.
