One governed software diagnostic
Define the first software decision before implementation becomes a guessing exercise.
The governed Software System Diagnostic examines one legacy .NET system, spreadsheet-and-email workflow, data/integration boundary, or architecture/release problem and returns a fundable decision. Price requires a written agreement.
Answer seven boundary questions to see the likely risk, missing evidence, human review needs, and best first offer. Your selections stay in this browser tab and are never submitted.
No account, upload, API, AI model, analytics event, email, or browser storage is used.

Problem
A software estimate is weak when trusted behavior, data, integration, release, and ownership boundaries are unclear.
Important .NET behavior is not documented or tested well enough to change safely
Users, records, approvals, exceptions, and reporting live across spreadsheets and email
Architecture, deployment, logs, rollback, recovery, or support ownership are unclear
One diagnostic, four tracks
The buyer selects the closest problem; TSmithCode defines the technical boundary.
User and workflow map, trusted-behavior inventory, source-system and data-ownership map, business rules and exceptions, integration and release risks, first implementation unit, validation and rollback plan, estimate, and build/narrow/pause/stop decision packet.
Legacy .NET modernization
Spreadsheet and email workflow replacement
Data and integration reliability
Architecture, release, and ownership
User, workflow, trusted-behavior, and ownership map
Source-system, data, rule, exception, and dependency inventory
First implementation unit with validation, rollback, estimate, and go/no-go recommendation
Next step
Written agreement starts the named diagnostic; payment does not authorize implementation.
The path begins with consultation intake because official billing is not commissioned. Implementation, migration, production access, third-party services, and ongoing support require a separate accepted scope.
No source code, credentials, customer data, or files are accepted by the public intake endpoint
The written diagnostic agreement does not include implementation, deployment, or migration
Security, environments, support, maintenance, licensing, and third-party costs remain explicit
The route is limited to scoped software consulting
What the engagement establishes
The first build decision includes release, privacy, security, support, and rollback reality.
Current behavior and accepted outcome examples
Test, validation, observability, release, rollback, recovery, and support evidence
Source-code, customer-data, credential, environment, and retention boundaries
Third-party, cloud, model-provider, licensing, quota, and operating-cost constraints
Human review, AI evaluation, correction, fallback, and accountable approval where applicable
Start the diagnostic or describe the system for a fit decision first.
Use consultation when users, trusted behavior, data, integrations, security, release, ownership, or the desired first decision are not clear enough to accept the governed diagnostic.
