Modernization Roadmap
Decide what to modernize, in what order, and why.
Modernization decisions are contested because cost, ownership, and dependency information usually sits in different places. This decision area brings them into one view so the sequence can be argued on evidence rather than preference.
Questions this decision area addresses
Which applications are in the portfolio, and who owns each one?
What does each application cost to run and maintain?
Which applications carry the most support, security, or end-of-life risk?
Which applications should be retired, replaced, retained, or re-platformed?
Which changes must move together because of shared dependencies?
What sequence fits the available budget and delivery capacity?
Typical inputs
Application inventory with business ownership
Run and maintenance cost by application
Support status, version, and end-of-life data
Integration and dependency records
Business criticality input from application owners
Available budget and delivery capacity
Resulting outputs

Disposition recommendation per application: retire, replace, retain, or re-platform

Phased sequence with cost and timing per phase
Risk summary for aging or unsupported systems
Assumptions and data-quality disclosures
Human review and approval
TekLedger produces the portfolio view and a recommended disposition and sequence. Application owners, architecture, and the CIO review each recommendation, apply operational context that is not present in the data, and approve the roadmap before it is funded or communicated.
