IBM i Modernization Buyer's Guide

Name the real pressure before picking a starting point

IBM i modernization projects often stall because buyers try to fix everything at once: interface, integration, staffing, and code all in one initiative. Before comparing vendors or approaches, buyers should identify the specific pressure driving the project, whether that is green-screen friction, staffing limits, customer-facing speed, or integration debt.

That pressure point should define what modernization means for this specific project, not a generic definition of the term.

Choose a phase with visible value and manageable risk

The most successful modernization projects start with a bounded phase that produces a visible result: a modernized interface for one workflow, an API that unlocks one integration, or a single reporting improvement. Buyers should resist the pull toward a comprehensive platform-first rollout before one phase has proven out.

Small, successful phases build the internal confidence and governance habits that larger modernization work will eventually need.

• Name the single biggest source of friction driving this project
• Choose a first phase that can show results within one budget cycle
• Identify who owns the decision if scope starts expanding

Match the approach to internal change tolerance

Modernization projects fail as often from change management problems as from technology problems. Buyers should be honest about how much disruption staff and business processes can absorb at once, and choose an approach and a vendor that fits that tolerance rather than an idealized pace of change.
