IBM Bob vs. X-Analysis AI: How These Tools Work Better Together

IBM Bob vs X-Analysis AI — two tools for smarter IBM i development

Two powerful tools leading the way in IBM i development are IBM Bob and Fresche’s X-Analysis AI. While IBM Bob focuses on program-level productivity, X-Analysis AI provides the critical system-level insights necessary for safe transformations. Together, they form a powerful combination that enables IT teams to modernize with confidence and precision.

This guide explores the unique capabilities of IBM Bob and X-Analysis AI, how they complement each other, and why they are better together for IBM i (AS/400) modernization.

Two Tools, One Goal: Smarter IBM i Development

To execute a successful modernization initiative, teams must equip themselves with tools that address both micro-level coding tasks and macro-level system architecture.

IBM Bob: Accelerating Program-Level Development

IBM Bob, also known as Project Bob, is IBM’s AI-powered Integrated Development Environment (IDE) for the IBM i platform. Built for real-time developer productivity, it provides assistance for writing, refactoring, and understanding RPG code directly within the development environment.

Key Features of IBM Bob

  • Writes and refactors RPG code with AI assistance
  • Documents programs automatically as you work
  • Explains unfamiliar code in plain language

IBM Bob accelerates development workflows by automating repetitive tasks and providing actionable insights, enabling developers to focus on high-value work while enhancing both productivity and code quality. While IBM Bob excels at the program level, it’s not designed for system-level modernization. To maximize its benefit, IT leaders should consider where Project Bob fits in your IBM i modernization strategy within the broader context of application transformation.

X-Analysis AI: Delivering System-Level Visibility

For comprehensive system-level visibility, X-Analysis AI fills a complementary role. X-Analysis AI is purpose-built to analyze, document, and modernize IBM i (AS/400) applications written in RPG, COBOL, and CA 2E (Synon). By delivering a holistic view of your entire application landscape, it gives teams the clarity required to plan and execute informed modernization initiatives.

Key Features of X-Analysis AI

  • Dependency Mapping: Tracks program, field, and variable dependencies to ensure highly accurate impact analysis across the entire application stack.
  • Business Rule Extraction: Uses advanced AI to identify and document business logic embedded deep within legacy code, making it accessible and understandable to both IT and business stakeholders.
  • Advanced Documentation: Automatically generates visual charts and logical flow diagrams to simplify cross-departmental collaboration and project planning.

XA-AI maps 30 years of system dependencies before a developer touches a single line.

IBM Bob and X-Analysis AI: What They Bring to the Table

While IBM Bob and X-Analysis AI serve distinct primary purposes in the modernization lifecycle, they share several core attributes that make them highly complementary tools for IBM i environments:

  1. AI-Powered Capabilities
    Both tools leverage artificial intelligence to simplify highly complex tasks. Whether you’re analyzing large volumes of legacy code or providing real-time programming assistance, AI integration delivers faster, more accurate results.
  2. Dedicated Focus on IBM i Development
    Both tools are specifically designed for IBM i (AS/400) environments, offering seamless compatibility with RPG, COBOL, and other foundational IBM i technologies that power your enterprise systems.
  3. Improved Team Productivity
    By automating time-consuming tasks like code documentation, impact analysis, and refactoring, these tools help your development teams work much more efficiently and focus on strategic innovation.
  4. Strategic Risk Reduction
    Each tool provides insights that reduce the risk of critical errors during modernization projects. By addressing vulnerabilities at both the system mapping and program execution levels, your team can deploy changes securely.

 

Better Together: How IBM Bob and X-Analysis AI Create a Seamless Workflow

Before your developers start refactoring with Bob, how are you making sure they understand the downstream impact of every change?

Modernizing IBM i applications requires both a deep understanding of legacy systems and the ability to implement code changes efficiently. IBM Bob and X-Analysis AI are most effective when used together. This integration creates a seamless, end-to-end workflow that combines high-speed developer productivity with comprehensive system intelligence.

Step 1: System Understanding with X-Analysis AI

Before making any code modifications, it’s essential to understand the broader system architecture. X-Analysis AI handles the heavy lifting by mapping complex dependencies, uncovering hidden architectural challenges, and extracting legacy business rules. This provides the critical structural insights needed to modernize your infrastructure safely.

Step 2: Hands-On Development with IBM Bob

Once the system-level groundwork is in place, IBM Bob accelerates the development and execution phases. Its AI-assisted coding features enable developers to refactor logic and document individual programs efficiently, significantly reducing the time spent on manual coding tasks.


The Unified Example Workflow

  1. Deploy X-Analysis AI to analyze the enterprise system, identify all downstream dependencies, and document embedded business rules.
  2. Transition to IBM Bob for hands-on coding and refactoring with total confidence, knowing exactly how every change impacts the broader system architecture.

Together, these tools forge a unified modernization stack. This powerful combination significantly reduces project risks, improves technical collaboration, and accelerates deployment timelines.


When to Use IBM Bob vs. X-Analysis AI

While IBM Bob and X-Analysis AI share the goal of improving IBM i development, they serve distinct purposes. Here is a technical comparison of the two platforms:
