In your "Practical Guide" reading this week, the emphasis is on defining an architectural process and approach. In your own words, please describe: 1. What are some considerations for selecting a specific architectural framework? 2. Why are quality attributes ("ilities") important when defining an architecture and why isn't it a good idea to "bolt" these on at a later date? 3. Please provide 2-3 considerations for evaluating an architecture. Only 1 or 2 paragraphs.

Defining an architectural process is pivotal for creating a robust and effective system that aligns with the needs of users and stakeholders. The selection of a specific architectural framework is influenced by various considerations. Firstly, the project’s unique requirements play a significant role; understanding the business context and technical needs ensures the chosen framework supports scalability, flexibility, and maintainability. For instance, using a framework like the Microservices Architecture allows for flexibility and agility in deployment but may not be suitable for all project types, particularly those that require tightly-coupled systems (Bass, Clements, & Kazman, 2013).

Secondly, the team's expertise should not be overlooked. Teams must be familiar with the architectural framework to effectively implement it, as certain frameworks may have steep learning curves or require specialized knowledge (Clements et al., 2018). Thirdly, existing technology stacks and integration capabilities are key considerations. The selected architectural framework must integrate seamlessly with current technologies to prevent costly overhauls (Tortorella, 2018). Additionally, organizational culture can influence the framework selection; for example, if a company fosters innovation and experiments frequently, a more flexible architecture may be preferable to a rigid monolithic structure (Kruchten, 2004).

Quality attributes, sometimes referred to as "ilities," are essential for defining architecture because they determine how well the system performs beyond its functional requirements. Examples include scalability, reliability, and security (Kazman et al., 2014). If quality attributes are not integrated into the architecture from the outset, there is a risk of inadequate performance or the need for costly rework later. For instance, "bolting on" security retroactively may lead to vulnerabilities that could have been avoided if security considerations were embedded in the initial design (McGraw, 2006). This approach often leads to systems that fail to meet user expectations and may struggle with regulatory compliance, ultimately undermining the project's success.

Evaluating an architecture is crucial to ensuring it meets the intended quality attributes and project requirements. One consideration is the architecture's alignment with business goals; does it support strategic objectives and project deliverables? Ensuring that the architecture supports the organization’s direction is imperative for long-term success (Breu & Hofstede, 2014). Another consideration is the architecture's adaptability; can it accommodate future changes in business needs or technology advances? Systems that are difficult to modify or extend can become costly to maintain, making adaptability a key trait for evaluation (Garlan, 2016). Finally, performance metrics, such as response times and failure rates, provide quantitative measures to assess the architecture’s efficacy against initial specifications.
