System Assessment & Documentation

Q: What if we have no source code access?

We can work from the running system -- tracing data flows, testing scenarios, and observing behavior. Source code accelerates the process, but we have methods for black-box analysis when code isn't available.

Q: Do we need this if we're replacing the whole system anyway?

A full replacement increases the need to understand what must be preserved, intentionally changed, archived, integrated, or retired. The assessment reduces unknowns, but remaining uncertainty is documented and carried into the migration plan rather than treated as eliminated.

Q: Can your documentation be used by other implementation partners?

Yes. We deliver structured documentation you own -- business process maps, data dictionaries, integration catalogs, and risk assessments. If you want to use the assessment output to guide implementation, it's yours.

Understand the system manufacturing depends on before changing it. Legacy applications often contain undocumented product, order, inventory, production, pricing, reporting, and integration logic. We recover the architecture, data flows, operating rules, dependencies, risks, and ownership required to make a responsible modernization decision.

The Problem

The business is planning replacement without a dependable model of what the current system does.

Modernization problems begin when a critical system is treated as old technology without first documenting the rules, records, interfaces, users, and operating knowledge the business still depends on.

What leaders see

Aging systems limit change and concentrate risk.

Support is difficult, integrations are fragile, and ordinary improvements depend on a shrinking group of people.

What is actually happening

The business logic is not fully understood.

Important rules, data, reports, workflows, and exceptions live in code, workarounds, and employee memory.

What gets worse

A rushed replacement threatens operating continuity.

The new system reaches testing before the team has proved what must be preserved or how each transition will be validated.

What Changes

What System Assessment & Documentation includes.

Legacy applications often contain undocumented product, order, inventory, production, pricing, reporting, and integration logic. We recover the architecture, data flows, operating rules, dependencies, risks, and ownership required to make a responsible modernization decision.

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.

Data Model Documentation

Map the tables, fields, relationships, transformations, and data flows required by the assessment scope. Identify authoritative, transactional, reference, and derived records.

Integration Mapping

Discover and document in-scope file transfers, APIs, database links, email triggers, jobs, and manual handoffs. Record unverified or inaccessible dependencies as explicit migration risks.

Dependency Analysis

Identify upstream and downstream dependencies -- which systems feed data in, which systems consume data out, and what breaks if something changes.

Technical Debt Inventory

Catalog customizations, workarounds, dead code, and technical debt. Distinguish between logic that must be preserved and logic that can be retired.

Knowledge Base Delivery

Deliver a structured, searchable knowledge base with assigned owners and review points so the client team and approved partners can maintain it through modernization.

How It Fits Manufacturing

How System Assessment & Documentation fits the manufacturing operation.

Legacy ModernizationWhat must be preserved, what can change safely, and whether integration, staged replacement, parallel running, or a smaller intervention is the sound path.

Governance dependencyModernization needs a verified account of what the current system does, who depends on it, how records move, what cannot fail, and how the business will validate each transition.

Knowledge and dependencies to preserve

business rules

critical records

interfaces

user workflows

support and recovery knowledge

What must be defined before engineering begins

What the manufacturing 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.

New material work begins in Launchpad so Metrotechs can validate the operating need, evidence, feasibility, architecture direction, and sequence before engineering begins.

Start With the Manufacturing Objective

Define the smallest sound response and delivery sequence.

Metrotechs determines what the operation actually requires before selecting technology. New material work begins in Launchpad so the evidence, feasibility, architecture direction, priorities, and sequence can be validated before engineering begins.

Discuss the Business Objective Start Your Transformation Roadmap

Metrotechs designs, builds, integrates, and supports the approved solution for the manufacturing operation.

A technical-service request does not bypass discovery. The proposed solution remains a working hypothesis until Metrotechs validates it in Launchpad.

Delivery sequence

How Metrotechs delivers System Assessment & Documentation.

Legacy applications often contain undocumented product, order, inventory, production, pricing, reporting, and integration logic. We recover the architecture, data flows,.

Stakeholder Interviews

Interview power users, IT staff, and business process owners. Capture tribal knowledge before it disappears.

Code Analysis

Analyze source code, database schemas, and configuration files. Automated tools plus manual review for complex business logic.

Data Flow Tracing

Trace selected critical records from entry through transformation, storage, interfaces, and output, noting evidence, uncertainty, and accountable owners.

Integration Discovery

Scan for file transfers, scheduled jobs, API calls, and database connections. Verify each integration with source and target system owners.

Documentation Delivery

Compile findings into a structured knowledge base with business process maps, data dictionaries, integration catalogs, and risk assessments.

FAQ

Questions that usually decide the scope.

Straight answers to what manufacturing leaders ask before committing budget to this work.

How long does a system assessment take?

The schedule depends on source and environment access, code and data volume, customization, interfaces, job schedules, documentation quality, stakeholder availability, and the decisions the assessment must support. We scope it from those boundaries.

What if we have no source code access?

Do we need this if we're replacing the whole system anyway?

Can your documentation be used by other implementation partners?
