PowerBuilder applications power core business processes at organisations that have been running them for 20 or 30 years. The platform is not dead, but the developer pool is shrinking fast — and the business logic locked inside these systems is irreplaceable.

The PowerBuilder problem

PowerBuilder had a strong run in enterprise and government environments through the 1990s and 2000s. It was used to build some genuinely complex systems: multi-screen data entry workflows, report-heavy financial applications, manufacturing and logistics tools.

Those systems are now running on infrastructure that was never designed to last this long. The developers who built them have retired. The organisations running them face an increasingly uncomfortable reality:

• PowerBuilder skills are genuinely rare and expensive to hire
• The applications contain business rules that were never documented
• Replacing the system requires understanding what it does — which requires either the source code or someone who remembers
• Failure during migration can be catastrophic for operations

This creates a paralysis that many organisations have lived with for years. The system is too risky to migrate, and too risky to keep.

What I do

I break the paralysis. I analyse the application — with or without source code — and produce the documentation and planning you need to make migration achievable.

• Application architecture documentation — datawindows, business objects, workflows
• Database schema analysis and data dictionary
• Business rule extraction from application logic
• Screen-by-screen functional specification of critical workflows
• Integration points and external system dependencies
• Technology platform options and migration approaches
• Phased migration plan with risk-ranked priorities

Who this is for

IT managers who need to present a realistic migration roadmap to leadership, with evidence that the risk has been assessed.

Operations teams whose daily work depends on a PowerBuilder system that nobody can support.

Finance teams running PowerBuilder-based reporting or financial workflows that the organisation has grown around.

Executives who know the platform risk is real but haven’t had a credible plan to address it.

Starting with assessment

A migration of a complex PowerBuilder system should never start with “build the replacement.” It should start with “understand the original.” The assessment produces the foundation documentation that makes everything else possible.
