Sprint schedule

• Sprint 1 — Foundation and Transactions: authentication, base navigation, categories, transaction CRUD, authorization, responsive form foundation.
• Sprint 2 — Budgets and Core Dashboard: monthly budgets, KPI summaries, balance calculations, budget utilization, transaction filters.
• Sprint 3 — Analytics and UX: category distribution, monthly trend reporting, dashboard refinement, mobile usability, accessibility improvements.
• Sprint 4 — Release Hardening: regression, security checks, performance verification, UAT, deployment rehearsal, production release.

RACI-style responsibilities

• Product Owner: Accountable for backlog priority and acceptance.
• Lead Web Developer: Accountable for architecture and technical quality.
• Web Developer: Responsible for implementation and development tests.
• QA Engineer: Responsible for independent verification and regression.
• UX/UI Designer: Responsible for user-flow and interface design.

Risk register

• R-01 Unauthorized data access: Probability Medium, Impact Critical. Controls: ownership checks, authorization tests, code review, least-privilege access.
• R-02 Incorrect monetary calculations: Probability Medium, Impact High. Controls: decimal data types, calculation unit tests, reconciliation tests.
• R-03 Scope expansion: Probability High, Impact Medium. Controls: release boundary, backlog prioritization, formal change IDs.
• R-04 Poor mobile usability: Probability Medium, Impact Medium. Controls: responsive design criteria and testing each sprint.
• R-05 Reporting performance: Probability Medium, Impact Medium. Controls: query indexes, bounded date ranges, aggregation review, performance tests.
• R-06 User-data loss: Probability Low, Impact Critical. Controls: automated backups, restore tests, migration controls.
• R-07 Delayed stakeholder decisions: Probability Medium, Impact Medium. Controls: scheduled reviews and Product Owner decision authority.

Change control

1. Record each new request using a change identifier such as CR-01.
2. Product Owner documents business value and priority.
3. Lead Developer and QA assess technical, security, testing, schedule, and dependency impact.
4. Do not disrupt committed sprint work unless the Product Owner explicitly swaps or cancels scope.
5. Schedule accepted changes into an appropriate future sprint.
6. Update affected requirements, designs, tests, risk records, and traceability entries.

Configuration management

• All source code is maintained in version control.
• Changes require peer review before integration.
• Database migrations are version controlled.
• Release versions receive immutable release tags.
• Secrets and environment-specific credentials are excluded from source control.
