Software Architecture: Principles, Patterns, and Practices
ANSI/IEEE Standard 471-2000:
Architecture is the fundamental organization of a system, embodied in its components, their relationships to each other and the environment, and the principles governing its design and evolution.
Perry and Wolf: Software Architecture = { Elements, Form, Rationale }
History of Software Architecture
- Agile Manifesto: In February 2001, 17 software developers met at the Snowbird resort in Utah to discuss lightweight development methods.
- Agile is not incompatible with or somehow
Software Development Methods: Testing, Agile, and Plan-Driven Approaches
Testing
Development Testing: The system is tested during development to discover bugs and defects. System designers and programmers are likely to be involved in the testing process.
Release Testing: A separate testing team tests a complete version of the system before it is released to the users. The goal is to check that the system meets the requirements of stakeholders.
User Testing: Users test the system in their own environment. Acceptance testing is one type of user testing where the customer

What is Software Architecture?
Software architecture refers to the fundamental structure of a software system. It comprises software components, the externally visible properties of those components, and the relationships between them.
What Does Software Architecture Enable for the Software Engineer?
- Analyze the effectiveness of the design in meeting the stated requirements.
- Consider architectural alternatives at a stage where making design changes is relatively easy.
- Reduce the risks associated with
Software Configuration Management Plan (SCMP) Essentials
Comprehensive Sheet for SCMP (Software Configuration Management Plan)
The Software Configuration Management Plan (SCMP) is critical to maintaining control over project artifacts, ensuring consistency, traceability, and controlled evolution of the software. Here’s a step-by-step detailed breakdown into all essential sections, with examples and implementation details.
1. Introduction
Purpose:
- Define the goals of configuration management (CM) for the project.
- Establish processes and tools to control changes,
Scrum Framework: Roles, Events, and Project Benefits
Introduction to Scrum
- Self-organization is key
- Collaboration instead of working against each other
- Fewer but clearly defined roles and rules
- Scrum is an empirical approach, a learning approach
- Inspired by practices in Rugby and Japan
Classic Projects vs. Agile Projects
Classic Projects
- A lot of documentation required
- Long time between releases
- No changes expected
- Slight communication and collaboration (handover)
- Bad quality, missing functionality, and dissatisfaction
Agile Projects
- Only needed documentation required
- Development
Understanding Requirements Engineering in Software Development
Requirements Engineering in Software Development
- Requirements engineering is the process of establishing the services that the customer requires from a system and the constraints under which it operates and is developed.
- The requirements themselves are the descriptions of the system services and constraints that are generated during the requirements engineering process.
What Is a Requirement?
- It may range from a high-level abstract statement of a service or of a system constraint to a detailed mathematical
