Valley Wide ORDERS Modernization Roadmap

This document tracks the phased modernization of Valley Wide Plastering's VB6 ORDERS application to a modern web-based ERP. The strategy uses parallel development with SQL Server as the common backend, allowing VB6 and web clients to coexist during transition.

Legend

  • Not started
  • [~] In planning
  • Completed
  • Priority: P1 (critical/blocking), P2 (important), P3 (nice-to-have)

Strategic Approach

End Goal: Modern web application replacing VB6 desktop client

Migration Strategy: Dual-client parallel development with gradual user adoption

  • SQL Server backend supports both VB6 and web clients simultaneously
  • VB6 continues production use while web client is developed
  • Users transition module-by-module based on beta testing
  • Zero-downtime migration with easy rollback per module

Timeline: 8-9 months to full production rollout

Phase 1: Foundation & Database Migration (Month 1)

Known Risks & Mitigation

Risk 1: Undocumented Business Rules

Impact: HIGH Probability: MEDIUM Mitigation:

  • Extensive beta testing with experienced users
  • Parallel VB6/web operation during transition
  • Module-by-module rollout (easy rollback)
  • Preserve VB6 source as reference

Risk 2: Certified Payroll Compliance Failure

Impact: CRITICAL (legal/contract violations) Probability: LOW (with proper testing) Mitigation:

  • Extensive testing with parallel VB6 comparison
  • Legal/compliance review before deployment
  • Keep VB6 as backup for payroll until proven
  • Gradual rollout to single payroll admin first

Risk 3: Positive Pay Bank Integration Failure

Impact: HIGH (fraud prevention failure) Probability: LOW (well-defined bank specs) Mitigation:

  • Validate output files against bank specifications
  • Test with banks before production use
  • Keep VB6 as backup until confirmed working
  • Monitor first production files closely

Risk 4: Performance Issues with Web Client

Impact: MEDIUM (user adoption) Probability: MEDIUM Mitigation:

  • Performance testing during development
  • Database indexing and query optimization
  • Caching strategies
  • Monitor response times during beta

Risk 5: User Resistance to Change

Impact: MEDIUM (adoption rate) Probability: MEDIUM Mitigation:

  • Early beta user involvement
  • Comprehensive training
  • Module-by-module adoption (users can stay on VB6)
  • Highlight mobile/web benefits (field access)

Success Criteria

Phase 1 Success (Database Migration)

  • VB6 running against SQL Server in production

Notes

  • This is a living document - update as features ship or requirements change
  • Checkboxes track implementation status: [ ] planned, [~] in progress, [x] completed
  • Priority levels guide sprint planning: P1 critical/blocking, P2 important, P3 nice-to-have
  • Effort estimates are approximate; adjust based on actual experience
  • Dependencies are noted in "Blocking" fields - resolve blockers first
