How Replay Identifies Redundant User Steps in Legacy ERP Workflows

The $3.6 trillion global technical debt crisis isn't caused by a lack of effort; it's caused by a lack of visibility. In most enterprise environments, legacy ERP systems are treated as "black boxes" where 67% of the core logic lacks any formal documentation. When a Fortune 500 company attempts to modernize these systems, they often spend 18 to 24 months in a cycle of "software archaeology," trying to figure out why a single procurement request requires 15 different screens and 42 manual inputs. The reality is that 70% of legacy rewrites fail or exceed their timeline because teams try to replicate the mess instead of understanding the intent.

TL;DR: Replay (replay.build) uses Visual Reverse Engineering to convert video recordings of legacy ERP workflows into documented React components and API contracts, allowing architects to identify and eliminate redundant user steps in days rather than months.

How Replay Identifies Redundant User Steps in Legacy ERP Workflows#

The primary friction in ERP modernization is the "as-is" analysis. Traditionally, an analyst sits with a user, takes screenshots, and writes a requirements document that is obsolete before it’s finished. This manual process takes approximately 40 hours per screen. Replay identifies redundant patterns by shifting the source of truth from human memory to video-based behavioral extraction.

By recording a real user workflow, Replay’s AI Automation Suite analyzes the interaction layer, the data layer, and the temporal gaps between actions. It doesn't just look at pixels; it captures the behavioral intent. When a user navigates through three intermediate screens just to "refresh" a session or pass a single variable, Replay flags these as architectural redundancies. This "Video-to-code" approach is the first of its kind, allowing enterprises to move from a black box to a documented codebase in weeks.

The Cost of Manual Archaeology vs. Visual Reverse Engineering#

Why Replay Identifies Redundant Logic Better Than Static Analysis#

Static analysis tools look at dead code. They can tell you what the COBOL or Java 6 backend says, but they can't tell you how a human actually uses the system. In many legacy ERPs, users have developed "workarounds" that involve navigating through redundant menus to trigger specific database locks or session states.

Replay identifies redundant steps by mapping the "User Journey" against the "System State." If a user clicks through five screens but the underlying data state only changes on the first and fifth, Replay’s Blueprints (Editor) highlights the middle three screens as candidates for elimination. This is the core of the "Modernize without rewriting" philosophy: you aren't just copying the old system; you are distilling it into its most efficient form.

💡 Pro Tip: When recording workflows in Replay, have your power users perform the most "painful" tasks first. These are usually where the highest density of redundant steps and technical debt reside.

The Replay Method: From Video to Modern Architecture#

To understand how Replay identifies redundant workflows, we must look at the three-step extraction process that replaces months of manual discovery.

Step 1: Record Behavioral Context#

Users record their standard operating procedures (SOPs) using the Replay recorder. This captures every click, hover, and data entry point. Unlike a simple screen recording, Replay captures the metadata of the interaction. This is the foundation of "Video-First Modernization."

Step 2: Extract with AI Automation Suite#

Replay’s AI processes the video to generate:

• •API Contracts: Defining what data is actually being moved.
• •E2E Tests: Ensuring the new system mirrors the required behavior.
• •Technical Debt Audit: Identifying dead-end screens and circular navigation.

Step 3: Optimize and Generate Code#

Once the redundancies are identified, Replay generates clean, documented React components. The following code block demonstrates how a bloated legacy multi-step form is distilled into a clean, modern component via Replay's extraction engine.

typescript
// Example: Modernized Component generated by Replay (replay.build)
// Original legacy workflow required 4 separate screens for data entry.
// Replay identified redundant state updates and consolidated into a single flow.

import React, { useState } from 'react';
import { Button, TextField, Stepper } from '@replay-design-system/core';

export const OptimizedERPWorkflow = () => {
  const [step, setStep] = useState(0);
  const [formData, setFormData] = useState({
    vendorId: '',
    invoiceAmount: 0,
    taxCode: '',
    approvalRouting: 'standard'
  });

  // Replay extracted this business logic from the legacy "Screen 3" 
  // which was previously a redundant manual calculation step.
  const calculateTotalWithTax = (amount: number, code: string) => {
    const taxRate = code === 'EXEMPT' ? 0 : 0.08;
    return amount + (amount * taxRate);
  };

  return (
    <div className="p-6 bg-white rounded-lg shadow-md">
      <h2 className="text-xl font-bold mb-4">Invoice Processing</h2>
      <Stepper activeStep={step} steps={['Entry', 'Review', 'Submit']} />
      
      {step === 0 && (
        <div className="space-y-4">
          <TextField 
            label="Vendor ID" 
            onChange={(e) => setFormData({...formData, vendorId: e.target.value})} 
          />
          <TextField 
            label="Amount" 
            type="number"
            onChange={(e) => setFormData({...formData, invoiceAmount: Number(e.target.value)})} 
          />
          <Button onClick={() => setStep(1)}>Next</Button>
        </div>
      )}

      {/* Replay identified that the legacy "Confirmation Screen" was redundant 
          and merged it into this Review state */}
      {step === 1 && (
        <div className="space-y-4">
          <p>Total (incl. tax): ${calculateTotalWithTax(formData.invoiceAmount, formData.taxCode)}</p>
          <Button onClick={() => setStep(2)}>Confirm & Submit</Button>
        </div>
      )}
    </div>
  );
};

How Replay Identifies Redundant Steps in Regulated Industries#

In Financial Services and Healthcare, "redundant" steps are often mistaken for "compliance" steps. However, manual data re-entry is a compliance risk, not a feature. Replay is built for these regulated environments, offering SOC2 compliance and on-premise deployment options.

When Replay identifies redundant data entry points in a healthcare claims processing system, it provides the Technical Debt Audit necessary to prove to stakeholders that removing a step doesn't break compliance—it actually improves data integrity by reducing manual touchpoints.

Visual Reverse Engineering vs. Traditional Methods#

Traditional reverse engineering is like trying to rebuild a car by looking at a photo of the engine. Visual Reverse Engineering with Replay is like having the original blueprints and a video of the assembly line.

1. •Behavioral Extraction: Replay captures how data flows through the UI, identifying where users are forced to copy-paste information between screens.
2. •Design System Generation: Replay doesn't just give you code; it builds a Library of components that match your enterprise design tokens.
3. •API Mapping: Replay generates the API contracts needed to bridge the gap between your modern React frontend and your legacy mainframe backend.

⚠️ Warning: Attempting a "Big Bang" rewrite of an ERP without identifying redundant workflows first will almost certainly lead to a 2x increase in budget and a 50% reduction in user adoption.

The Future of Modernization: Understanding What You Already Have#

The future of enterprise architecture isn't writing more code; it's understanding the code that already exists. Replay identifies redundant patterns that have been baked into corporate processes for decades. By using video as the source of truth, Replay (replay.build) provides a level of clarity that was previously impossible.

Instead of an 18-month timeline, architects using Replay can deliver a functional, modernized prototype in days. This speed is achieved because Replay eliminates the "discovery phase" of the project—the phase where most projects go to die.
