What leaders see
Work keeps moving, but only because people fill the gaps.
Teams rely on manual checks, side files, rekeying, status meetings, and individual knowledge to keep the process alive.

Legacy Modernization · Assessment
System Assessment & Documentation
Understand your legacy system before you try to replace it. Most legacy modernizations fail because nobody fully understands what the old system actually does. We reverse-engineer your legacy system's business logic, data flows, and integrations -- creating documentation that probably never existed.
01
The Problem
Nobody Fully Understands the System You're Replacing
The problem is not one broken tool. It is an operating gap between who owns the work, which record can be trusted, and how exceptions move through the business.
What is actually happening
The workflow has no clean source of truth.
Records, rules, approvals, and handoffs are split across systems, so each step introduces delay or reconciliation.
What gets worse
Automation amplifies the weak spots.
The faster the business moves, the more bad data, exception work, and decision ambiguity compound across the operation.
02
What Changes
What System Assessment & Documentation includes.
Most legacy modernizations fail because nobody fully understands what the old system actually does. We reverse-engineer your legacy system's business logic, data flows, and integrations -- creating documentation that probably never existed.
01
Business Logic Extraction
Reverse-engineer business rules from running code -- pricing logic, order workflows, allocation rules, and approval chains. Document what the system actually does, not what someone thinks it does.
02
Data Model Documentation
Map every table, field, relationship, and data flow. Identify master data, transactional data, and the transformations between them.
03
Integration Mapping
Discover and document every integration -- file transfers, API calls, database links, email triggers, and manual handoffs. Nothing gets missed during migration.
04
Dependency Analysis
Identify upstream and downstream dependencies -- which systems feed data in, which systems consume data out, and what breaks if something changes.
05
Technical Debt Inventory
Catalog customizations, workarounds, dead code, and technical debt. Distinguish between logic that must be preserved and logic that can be retired.
06
Knowledge Base Delivery
Deliver a structured, searchable knowledge base -- not a 500-page PDF. Living documentation that your team and vendors can reference throughout the modernization.

What Launchpad defines before engineering begins
- What the business needs to change and why.
- Which systems, records, risks, and readiness gaps shape the work.
- What should be built, how it fits the architecture, and in what order.

FAQ
Questions that usually decide the scope.
Straight answers to what operators ask before committing budget to this work.
Typically 4-8 weeks depending on system complexity. An AS/400 with 20 years of customization takes longer than a 5-year-old packaged ERP. We scope the assessment based on the system and your modernization goals.
