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

  • Application portfolio with cost and ownership attached to each entry

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

  • Dependency clusters that need to move together

  • 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.
