  • Focus: Step-by-step process for capturing and documenting data migration requirements.

Key Challenges for Business Analysts

  • Absence of User Interface:
    • Business analysts struggle to document requirements without user interfaces.
    • Functional Requirement Documents usually include screen mockups, which are missing in data migration projects.

Step-by-Step Process for Data Migration

1. Data Analysis

  • Importance: Identify data discrepancies, bad data, and missing data.
  • Common issues:
    • Lack of validations in previous applications leading to bad data accumulation.
    • Mandatory fields left blank or filled with junk data.

2. Discussion with Customer

  • Analyze findings and discuss with the customer.
  • Possible actions include:
    • Deleting records with bad data.
    • Replacing old values with new ones.
    • Adding new values for missing data.

3. Data Mapping Table

  • Purpose: Clarify source data modifications and new target data to be injected.
  • Includes business rules for technical team guidance on modifying data sets.
  • Example:
    • Update all records for Europe region contacts to a new contact name.
  • Important for documenting the format and necessary updates for technical migration.

4. Functional Requirements Specs Template

  • Modify existing templates to reflect data migration requirements.
  • Include a section for the data mapping table and any additional technical information needed.

Techniques for Data Migration Projects

  1. Interviews:

    • Conduct interviews with stakeholders to gather data migration requirements.
  2. Workshops and Brainstorming Sessions:

    • Useful for complex migrations; brings stakeholders together to clarify requirements.
  3. Interface Analysis:

    • Understand how data is interfaced with different applications.
    • Important to note that databases may be used across multiple applications.
  4. Business Rules Analysis:

    • Create business rules for data modifications, clarifying how changes should be applied.
  5. Decision Trees:

    • Useful for depicting conditional changes in data, e.g., eligibility criteria.

Conclusion

  • Understanding data formats and applicable business rules is crucial for success.
