3、onCurrent State SummaryBaseline Capabilities(what we have)Static Code Analysis(WCA4Z-Understand,Rexx)-Prompt engineering(Human)-AI LLM Pro:We have the tools,developers can self-service Con:Lacks a comprehensive orchestration process from discovery-code summary-epic/story creation-forward engineering

4、Accelerators Tools help orchestrate the process from code discovery to forward engineeringPro:Adds a discipline and process to code modernization,may be able to partner with a vendor and use their tooling(included in effort)to produce defined outcomes(turnkey an effort),adds a framework to fine tune

5、 modelsCon:Many of the tools exhibit more marketing than substanceCharles Schwab CorporationBusiness Context and Challenges ADD Information Classification LabelCurrent LandscapeComplex legacy systems with intricate interdependenciesVery high manual effort in understanding and documenting application

6、 structures and interdependencies.Increased risk of errors and inefficiencies due manual effortChallengesTime-consuming impact analysis for application changes.Difficulty in visualizing job flows and data lineage.Identifying and eliminating redundant or dead code.Complex program calls in monolithic
