1. Introduction
This case study explores the implementation of interoperability requirements at GlobalLogistics Inc., a multinational logistics company, using the TOGAF Architecture Development Method (ADM). The focus is on ensuring seamless information and service sharing across the enterprise and its extended network of partners and suppliers.
2. Background
GlobalLogistics Inc. operates in a highly competitive and dynamic industry, requiring efficient and integrated logistics solutions. The company’s legacy systems and disparate applications hindered its ability to share information and services effectively. To address these challenges, GlobalLogistics Inc. embarked on a project to define and implement interoperability requirements using the TOGAF ADM.
3. Objectives
The primary objectives of the interoperability project were:
- To define and establish interoperability requirements across the enterprise and extended enterprise.
- To ensure seamless information and service sharing among internal departments and external partners.
- To improve operational efficiency and decision-making through integrated data and services.
- To enhance customer satisfaction through streamlined and integrated logistics services.
4. Interoperability Requirements
4.1 Overview
Interoperability is defined as “the ability to share information and services.” For GlobalLogistics Inc., defining the degree of information and service sharing was crucial for achieving its operational and strategic goals. The TOGAF ADM provided a structured approach to defining and implementing interoperability requirements across various phases of the architecture development process.
4.2 Defining Interoperability
GlobalLogistics Inc. categorized interoperability into three main types:
- Operational or Business Interoperability: Defines how business processes are shared.
- Information Interoperability: Defines how information is shared.
- Technical Interoperability: Defines how technical services are shared or connected.
Additionally, the company considered interoperability from an IT perspective, focusing on:
- Presentation Integration/Interoperability: A common look-and-feel approach through a portal-like solution.
- Information Integration/Interoperability: Seamless sharing of corporate information between applications.
- Application Integration/Interoperability: Integrated and shareable corporate functionality.
- Technical Integration/Interoperability: Common methods and shared services for communication, storage, processing, and access to data.
4.3 Enterprise Operating Model
The enterprise operating model determined the necessary level of business process integration and standardization for delivering goods and services to customers. For GlobalLogistics Inc., the operating model indicated the need for a shared services environment, which was defined in Phase A (Architecture Vision) and refined in Phase B (Business Architecture).
4.4 Refining Interoperability
GlobalLogistics Inc. refined its interoperability requirements to ensure they met the needs of the enterprise and extended enterprise. The company adopted the Degrees of Interoperability model, which included:
- Degree 1: Unstructured Data Exchange: Exchange of human-interpretable unstructured data.
- Degree 2: Structured Data Exchange: Exchange of human-interpretable structured data.
- Degree 3: Seamless Sharing of Data: Automated sharing of data based on a common exchange model.
- Degree 4: Seamless Sharing of Information: Universal interpretation of information through data processing based on cooperating applications.
4.5 Determining Interoperability Requirements
The company used brainstorming sessions and gap analysis results to identify and address interoperability requirements. A matrix was created to detail the information and service sharing requirements between stakeholders and systems.
Example:
| Stakeholders | A | B | C | D | E | F | G |
|---|---|---|---|---|---|---|---|
| A | 2 | 3 | 2 | 3 | 3 | 3 | |
| B | 2 | 3 | 2 | 3 | 2 | 2 | |
| C | 3 | 3 | 2 | 2 | 2 | 3 | |
| D | 2 | 2 | 2 | 3 | 3 | 3 | |
| E | 4 | 4 | 2 | 3 | 3 | 3 | |
| F | 4 | 4 | 2 | 3 | 3 | 2 | |
| G | 2 | 2 | 3 | 3 | 3 | 3 |
4.6 Reconciling Interoperability Requirements with Potential Solutions
The Enterprise Architect at GlobalLogistics Inc. ensured that there were no interoperability conflicts, especially when reusing existing Solution Building Blocks (SBBs) and Commercial Off-The-Shelf (COTS) packages. The most significant issue addressed was business interoperability, ensuring that embedded business processes in SBBs or COTS aligned with the company’s requirements.
