Modernization

Legacy and Technical Debt Management

A method for businesses carrying systems that still work and still cost. Debt is classified by business impact, then reduced inside normal delivery without betting on a full rewrite.

When businesses engage Blobb for this

  • A working system absorbs more engineering time each quarter
  • A full rewrite has been proposed without a credible transition plan
  • Known debt competes with product work without a common way to prioritize it
  • Important behavior exists only in old code and individual memory

What the work involves

Blobb inventories technical debt and classifies it by revenue, risk, cost, and delivery impact. A remediation sequence is built to fit inside normal product delivery. Where replacement is needed, the old system is reduced behind stable boundaries using incremental migration. A full rewrite is treated as the highest-risk option, not the default.

What you get

  • A debt register linked to business impact
  • A remediation sequence with owners and effort
  • Stable boundaries for incremental replacement
  • A migration and rollback plan
  • Measures that show whether debt is decreasing

How it is engaged

Blobb usually recommends assessing the system before setting a modernization sequence, because the most visible debt is not always the highest priority. That assessment can be a full architecture audit or a focused review, followed by a modernization program or a roadmap your team can execute.
