Introduction

A System Scope Diagram is a high-level representation of a system, showcasing its boundaries and interactions with external actors. In the context of the Condo Rental Platform, this diagram will serve as a crucial artifact for future design and risk discussions. In this article, we will delve into the creation of a concise context diagram, also known as a level-0 Data Flow Diagram (DFD), which will identify key actors and their information exchanges.

Objective

The primary objective of this task is to create a System Scope Diagram that clearly defines the Condo Rental Platform as a single box, encompassing all external actors and their information exchanges. This diagram will provide a foundation for future design and risk discussions, ensuring that all stakeholders are on the same page.

Task Description

To achieve this objective, we will model a concise context diagram, identifying the following actors and their information exchanges:

  • Landlord: The property owner who rents out their condo to tenants.
  • Tenant: The individual or group renting the condo from the landlord.
  • Payment Processor: The service responsible for processing payment transactions between the tenant and the landlord.
  • Email/SMS Service: The service used for communication between the landlord, tenant, and other external actors.
  • Admin: The system administrator responsible for managing the Condo Rental Platform.
  • External Identity Provider: The service used for authentication and authorization purposes.

Each arrow in the diagram must be labeled with the main data exchanged between the actors.

Implementation

To create the System Scope Diagram, we will utilize the draw.io / diagrams.net tool. The style will be as follows:

  • One rectangle for the system
  • Stick-figure icons (or ellipses) for actors
  • Straight arrows with labels

The diagram will be committed to the /docs/diagrams/ directory.

Subtasks

To ensure the successful creation of the System Scope Diagram, we will complete the following subtasks:

List Actors & Data Exchanges

We will identify and list all actors and their information exchanges, ensuring that we capture all relevant data.

Draft Diagram (draw.io XML)

Using the draw.io / diagrams.net tool, we will create a draft diagram, including all actors and their information exchanges.

Peer Review with Team

We will conduct a peer review with the team to ensure that the diagram accurately represents the Condo Rental Platform and its interactions with external actors.

Testing & Debugging

To ensure the quality of the System Scope Diagram, we will perform the following testing and debugging tasks:

Verify Labels are Legible at 100% Zoom in the Exported PDF

We will verify that all labels in the diagram are legible at 100% zoom in the exported PDF.

Quick Walkthrough with Teammate

We will conduct a quick walkthrough with a teammate to ensure that we see all actors and no internal components in the diagram.

Deadline

The deadline for completing this task is March 28, 2025, at 23:59 AST.

Benefits of a System Scope Diagram

A System Scope Diagram provides several benefits, including:

Clear System Boundaries: The diagram clearly defines the system boundaries, ensuring that all stakeholders understand the scope of the Condo Rental Platform.

  • Improved Communication: The diagram facilitates communication among stakeholders, ensuring that everyone is on the same page.
  • Reduced Risk: The diagram helps identify potential risks and areas for improvement, reducing the likelihood of errors and issues.
  • Enhanced Design: The diagram provides a foundation for future design discussions, ensuring that the Condo Rental Platform is designed with the needs of all stakeholders in mind.

Conclusion

Introduction

A System Scope Diagram is a high-level representation of a system, showcasing its boundaries and interactions with external actors. In the context of the Condo Rental Platform, this diagram will serve as a crucial artifact for future design and risk discussions. In this article, we will address some of the most frequently asked questions about System Scope Diagrams.

Q: What is a System Scope Diagram?

A System Scope Diagram is a high-level representation of a system, showcasing its boundaries and interactions with external actors. It is a visual representation of the system, including all external actors and their information exchanges.

Q: Why is a System Scope Diagram important?

A System Scope Diagram is important because it provides clear system boundaries, improves communication among stakeholders, reduces risk, and enhances design. It ensures that all stakeholders understand the scope of the system and are on the same page.

Q: What are the benefits of a System Scope Diagram?

The benefits of a System Scope Diagram include:

  • Clear System Boundaries: The diagram clearly defines the system boundaries, ensuring that all stakeholders understand the scope of the system.
  • Improved Communication: The diagram facilitates communication among stakeholders, ensuring that everyone is on the same page.
  • Reduced Risk: The diagram helps identify potential risks and areas for improvement, reducing the likelihood of errors and issues.
  • Enhanced Design: The diagram provides a foundation for future design discussions, ensuring that the system is designed with the needs of all stakeholders in mind.

Q: How is a System Scope Diagram created?

A System Scope Diagram is created by identifying all external actors and their information exchanges. The diagram is then drawn using a tool such as draw.io / diagrams.net, with a single rectangle for the system, stick-figure icons (or ellipses) for actors, and straight arrows with labels.

Q: What are the key elements of a System Scope Diagram?

The key elements of a System Scope Diagram include:

  • System: The system being represented, in this case, the Condo Rental Platform.
  • Actors: The external actors interacting with the system, including the landlord, tenant, payment processor, email/SMS service, admin, and external identity provider.
  • Information Exchanges: The data exchanged between the actors, including payment information, rental agreements, and communication.

Q: How is a System Scope Diagram used?

A System Scope Diagram is used to facilitate communication among stakeholders, identify potential risks and areas for improvement, and enhance design. It provides a foundation for future design discussions and ensures that all stakeholders are on the same page.

Q: What are some common mistakes to avoid when creating a System Scope Diagram?

Some common mistakes to avoid when creating a System Scope Diagram include:

  • Omitting key actors or information exchanges: Ensure that all relevant actors and information exchanges are included in the diagram.
  • Using unclear or ambiguous labels: Use clear and concise labels to avoid confusion.
  • Failing to review and revise the diagram: Review and revise the diagram regularly to that it accurately represents the system.

Conclusion

In conclusion, a System Scope Diagram is a crucial artifact for any system, providing clear boundaries and interactions with external actors. By understanding the benefits, key elements, and common mistakes to avoid, we can create a comprehensive System Scope Diagram for the Condo Rental Platform, ensuring that all stakeholders are on the same page and that the system is designed with the needs of all users in mind.
