Architecture Patterns Checklist

- [ ] Understand Requirements
  - [ ] Gather and analyse the functional and non-functional requirements of the project.
- [ ] Identify Suitable Patterns
  - [ ] Review common architecture patterns (e.g., MVC, Microservices, Layered, Event-Driven).
  - [ ] Select patterns that align with project requirements and constraints.
- [ ] Design Architecture
  - [ ] Create high-level diagrams illustrating the chosen architecture patterns.
  - [ ] Define components, their interactions, and data flow.
- [ ] Document trade-offs
  - [ ] Document the advantages and disadvantages of the selected patterns.
  - [ ] Justify the choice of patterns based on project needs.
- [ ] Review and Validate

Appropriate Patterns

Here are some common software architecture patterns and their typical use cases:

• Model-View-Controller (MVC): Suitable for web applications with a clear separation between data (Model), user interface (View), and business logic (Controller).
• Layered Architecture: Useful for applications that benefit from separation of concerns, with distinct layers for presentation, business logic, and data access.
• Event-Driven Architecture: Best for applications that need to respond to events asynchronously, such as real-time systems.

Decision Framework

When selecting architecture patterns, consider the following framework:

• Scalability: Will the pattern support future growth in users and data?
• Maintainability: Does the pattern facilitate easy updates and modifications?
• Performance: Will the pattern meet the performance requirements of the application?
• Complexity: Is the pattern appropriate for the complexity of the project, or does it introduce unnecessary overhead?
• Team Expertise: Does the development team have experience with the chosen patterns?

Output Template

When documenting the architecture patterns applied, use the following template:

# Decision Record: [What was decided]

## Project Overview

A brief summary of the project, its purpose, and main features.

## Options Considered

A list of architecture patterns considered for the project.

## Trade-offs

A detailed analysis of the advantages and disadvantages of each considered pattern.

## Decision

The chosen architecture.

## Consequences

A summary of the expected outcomes and any potential challenges associated with the chosen architecture.
