Scope
Bounded estate
Systems, owners, artifacts, and controls in scope
Method
Source plus SME
Code evidence paired with expert context
Evidence
Source backed
Findings tied to code, jobs, data, and reviews
Output
Retention package
Documentation written for handoff and review
Scope
A useful assessment shows where the legacy behavior sits, which teams depend on it, and what proof is needed before change.

Legacy estate
Batch windows, online transactions, files, reports, controls, exception paths, and handoffs
Decision support

Legacy estate
Known experts, operating routines, testing gaps, owner decisions, and open questions
Decision support
Choose what to document, validate, hand off, and review first
Assessment path
The work is scoped enough to move quickly, but specific enough for engineering, audit, and business owners.
Assessment path · 01 / 04
Business impact
Agree on systems, repositories, jobs, files, owners, and the decision the assessment must support.
Assessment outputs
A readable list of programs, jobs, copybooks, interfaces, data stores, owners, and unresolved gaps.
Assessment path · 02 / 04
Business impact
Build dependency, lineage, control-flow, and business-rule views from source artifacts.
Assessment outputs
Source-backed paths that show how data, rules, jobs, transactions, reports, and downstream systems connect.
Assessment path · 03 / 04
Business impact
Validate findings with application, operations, data, and audit stakeholders.
Assessment outputs
Plain-language findings on fragile logic, weak evidence, missing ownership, batch constraints, and audit exposure.
Assessment path · 04 / 04
Business impact
Deliver maps, rule catalogs, runbooks, interview notes, risks, open questions, and a practical next-step plan.
Assessment outputs
A summary of artifacts, reviewers, dependencies, open questions, and the next work plan for controlled rollout.
Assessment outputs
Each output is written so a buyer can use it in a planning meeting, audit review, or knowledge handoff.

Risk priorities
COBOL knowledge risk is often an evidence problem before it is a code problem.
Business impact
Critical calculations or exceptions sit inside paragraphs, copybooks, tables, or old run procedures.
Control focus
Create a source-cited rule catalog and review it with system owners.
Business impact
One change can affect jobs, reports, files, interfaces, and downstream teams that were not in the original plan.
Control focus
Map blast radius before work is estimated or scheduled.
Business impact
Teams cannot explain why a rule exists, who reviewed it, or which source artifacts support it.
Control focus
Keep findings tied to evidence, reviewers, timestamps, and open questions.
Diagnostic questions
04 Diagnostic questions
Which systems and data feeds are inside the decision scope?
Which rules must be explained to business, audit, or operations teams?
Where do batch windows, files, copybooks, and interfaces constrain change?
What evidence is required before leaders can trust controlled rollout?
