Perform Mainframe Knowledge Gap Analysis

**Description**

We need to identify gaps in our understanding of the mainframe application by reviewing available documentation, architecture artifacts, and business stakeholder inputs so that we can conduct a focused and efficient knowledge-transfer session with the Mainframe Support Team.

Background

- Mainframe documentation has been reviewed.
- Initial target architecture has been developed.
- Business domain initial walkthrough has been completed with business stakeholders on Aug 5.
- Mainframe SME/support engagements incur additional cost and should be optimized.
- The objective is to minimize the number of SME sessions by preparing a consolidated list of unresolved questions.

**Tasks**

Review existing mainframe documentation.
Review architecture diagrams and application inventory.
Review notes and outcomes from business stakeholder sessions.
Identify gaps, assumptions, and unresolved questions.
Categorize questions (Business Logic, Data, Integrations, Technical Architecture, Operations & Support, Migration Risks)
Prioritize questions (Critical, High, Medium, Low)
Consolidate findings into a single questionnaire for SME review.

**Acceptance Criteria**

- [ ] Relevant artifacts are reviewed.
- [ ] Unknowns and assumptions are documented.
- [ ] Questions are categorized and prioritized.
- [ ] Duplicates are removed.
- [ ] A consolidated SME questionnaire is produced.
- [ ] Questions requiring Mainframe Support Team clarification are identified.

**Deliverable**

A document or spreadsheet containing (example):

- Why the information is needed
- Priority
- Impact if unanswered
- Owner

Start by reviewing the existing mainframe documentation, architecture diagrams, application inventory, and business stakeholder notes named in the issue. Consolidate documented gaps, assumptions, and unresolved questions into a categorized and prioritized questionnaire, remove duplicates, and obtain Product Owner and Solution Architect review before the SME session.
