1. Introduction
This case study explores the implementation of an enterprise-wide Enterprise Resource Planning (ERP) system using the TOGAF Architecture Development Method (ADM) migration planning techniques. The focus is on a large manufacturing company aiming to transition from its legacy systems to a modern ERP solution. The migration planning techniques employed include the Implementation Factor Catalog, Consolidated Gaps, Solutions, and Dependencies Matrix, Architecture Definition Increments Table, Transition Architecture State Evolution Table, and Business Value Assessment Technique.
2. Background
The manufacturing company, Global Manufacturing Inc., has been operating with a mix of legacy systems for over two decades. These systems are outdated, lack integration, and hinder the company’s ability to scale and innovate. To address these challenges, the company decided to implement a new ERP system that would streamline operations, improve data accuracy, and enhance decision-making capabilities.
3. Objectives
The primary objectives of the ERP implementation project were:
- To replace the legacy systems with a modern, integrated ERP solution.
- To improve operational efficiency and data accuracy.
- To enhance decision-making capabilities through real-time analytics.
- To ensure a smooth transition with minimal disruption to ongoing operations.
4. Migration Planning Techniques
4.1 Implementation Factor Catalog
The Implementation Factor Catalog was used to document factors impacting the ERP implementation and migration plan. The catalog included risks, issues, assumptions, dependencies, actions, and impacts.
Example:
| Implementation Factor Catalog | ||
|---|---|---|
| Factor | Description | Deduction |
| Change in Technology | Replacement of legacy systems with a modern ERP solution. | – Need for extensive user training and data migration. – Potential for significant operational improvements. |
| Data Integration | Integration of data from multiple legacy systems into the ERP. | – Requires data cleansing and mapping. – Ensures data accuracy and consistency. |
| User Training | Training for all users on the new ERP system. | – Essential for user adoption and effectiveness. – Should be conducted in phases to manage workload. |
4.2 Consolidated Gaps, Solutions, and Dependencies Matrix
The Consolidated Gaps, Solutions, and Dependencies Matrix was used to group the gaps identified in the domain architecture gap analysis results and assess potential solutions and dependencies.
Example:
| Consolidated Gaps, Solutions, and Dependencies Matrix | ||||
|---|---|---|---|---|
| No. | Architecture | Gap | Potential Solutions | Dependencies |
| 1 | Business | Lack of integrated business processes | Implement ERP with standardized processes | Requires process re-engineering |
| 2 | Application | Outdated legacy applications | Replace with ERP modules | Data migration and integration |
| 3 | Information | Siloed data sources | Centralized data management in ERP | Data cleansing and mapping |
4.3 Architecture Definition Increments Table
The Architecture Definition Increments Table was used to plan a series of Transition Architectures outlining the status of the Enterprise Architecture at specified times.
Example:
| Architecture Definition · Project Objectives by Increment | ||||
|---|---|---|---|---|
| Project | Q1 2023 | Q2 2023 | Q3 2023 | Comments |
| Transition Architecture 1: Preparation | Transition Architecture 2: Initial Operational Capability | Transition Architecture 3: Full Operational Capability | ||
| ERP Implementation | Data migration and cleansing | Core modules implementation (Finance, Procurement) | Advanced modules implementation (Supply Chain, CRM) | Phased approach to manage risk and ensure smooth transition |
| User Training | Initial training for core users | Training for finance and procurement teams | Training for supply chain and CRM teams | Phased training to manage workload |
4.4 Transition Architecture State Evolution Table
The Transition Architecture State Evolution Table was used to show the proposed state of the architectures at various levels using the defined taxonomy.
Example:
| Architectural State using the Technical Reference Model | ||||
|---|---|---|---|---|
| Sub-Domain | Service | Transition Architecture 1 | Transition Architecture 2 | Transition Architecture 3 |
| Infrastructure Applications | Data Management Services | Legacy systems (replace) | ERP data management (transition) | ERP data management (new) |
| Information Exchange Services | Legacy systems (replace) | ERP integration (transition) | ERP integration (new) |
4.5 Business Value Assessment Technique
The Business Value Assessment Technique involved creating a matrix based on a value index dimension and a risk index dimension. The value index included criteria such as compliance to principles, financial contribution, strategic alignment, and competitive position. The risk index included criteria such as size and complexity, technology, organizational capacity, and impact of a failure.
Example:
