Architecture Lifecycle Issues
From Suhrid.net Wiki
Architecture Based Process
- Establish business case for the system. e.g. Product cost, time to market.
- Understand the requirements
- Use cases, prototypes
- Quality attributes
- Commonality & variability from previous/future systems - domain analysis.
- Develop the architecture - use tactics, styles.
- Document the architecture - using variety of views and ADL.
- Analyse or evaluate the architecture.
- Implement product based on the architecture.
- Ensure that implementation conforms with architecture.
Process Recommendations
- Architecture should be a product of a single architect or a small group of architects with a single leader.
- Arch should have both functional reqs and an articulated, prioritized list of quality attributes.
- Arch should be well documented with atleast one static view and one dynamic view.
- Arch should be circulated to all stakeholders who should actively review.
- Arch should be analysed for quantitative measures and formally evaluated for qualitative properties.
- Should lend itself to incremental implementation via creation of a skeletal system.
Global Analysis
- The purpose of global analysis is to analyse the factors that influence the architecture and develop strategies for accommodating these factors in the architecture design.
- Three types of factors:
- Organizational factors
- Technological factors
- Product factors
