The allocated case, a public institution that heavily relies on IS/IT, and the approach suggested

To prepare a Business Requirements Specification (BRS) for a core system used by a public institution, follow these steps:

1. Identify the Core System

• 
  Research the Organization: Review the organization's website, annual reports, and other publicly available documents to determine which core system is critical to their operations.


• 
  Select the System: Identify a system that is central to the organization’s IT infrastructure and operations. For instance, if the organization is a government department, the core system might be related to public records management, financial processing, or human resources.

2. Study and Understand the Core System

• 
  System Overview: Describe the core system, including its main functions, purpose, and the technology stack it uses.


• 
  User Groups: Identify and categorize the different user groups that interact with the system (e.g., administrators, end-users, external stakeholders).


• 
  Subsystems/Modules: Break down the core system into its subsystems or modules. Describe the functionality of each and how they interact with each other.


• 
  Relationships: Document the relationships between different subsystems/modules and how they integrate with external systems.

3. Document the System Perspectives

• 
  Functional Requirements: Detail the functionalities that the core system must provide. This includes user needs, system operations, and data processing requirements.


• 
  Non-Functional Requirements: Address performance attributes such as security, usability, reliability, and scalability.


• 
  Business Rules: Outline any business rules that govern the system’s operations, including compliance with regulations or internal policies.

4. Understand the Operating Environment

• 
  Technical Environment: Describe the hardware, software, and network infrastructure that supports the core system.


• 
  Organizational Environment: Discuss the organizational context, including any relevant processes, organizational structure, and external factors that impact the system.


• 
  Regulatory and Compliance Requirements: Identify any legal or regulatory requirements that the system must adhere to.

5. Prepare the Business Requirements Specification Document

Using a standard template will help ensure that your BRS is professional and complete. Here's a suggested structure for the document:

1. Introduction

• Purpose of the Document


• Scope


• Definitions and Acronyms

2. System Overview

• System Description


• Core Functions


• User Groups

3. Functional Requirements

• Detailed Requirements


• Use Cases or User Stories

4. Non-Functional Requirements

• Performance Requirements


• Security Requirements


• Usability Requirements

5. Business Rules

• Rules and Regulations


• Compliance Requirements

6. Subsystems/Modules

• Description of Subsystems/Modules


• Relationships and Dependencies

7. Operating Environment

• Technical Environment


• Organizational Environment


• Regulatory and Compliance Requirements

8. Appendices

• Glossary


• References


• Additional Information

Tips

• 
  Clarity: Ensure that the document is clear and unambiguous. Avoid jargon or overly technical language where possible.


• 
  Stakeholder Involvement: Engage stakeholders during the preparation process to validate requirements and assumptions.


• 
  Review and Feedback: Have the document reviewed by relevant stakeholders to ensure accuracy and completeness.

By following these steps and using a standard template, you will create a comprehensive and professional Business Requirements Specification document that meets the needs of the public institution.
