- 2. Contents Introduction Goals of architecture reviews Types of review Basic review flow Work product and plan Review packages Benefits of architecture review
- 3. Architecture Reviews Architecture reviews are an effective way of ensuring design quality and addressing architectural concerns The principle objectives of a software architecture review are to assess an architecture’s ability to deliver a system capable of fulfilling the quality requirements and to identify potential risks
- 4. Goals of Architecture Reviews Architecture reviews ensure: The architecture of a system is documented It provides a coherent description of the system It is conformant to State and Agency principles, standards and plans It is compatible with the legacy technical landscape That the chosen technology and design is likely to achieve the project’s goals and objectives
- 5. Types of review Project process reviews Project Initiation Review Approve project goals, strategy, concept Iterative projects may propose how they will articulate architecture and design Planning / Design Review Approve project architecture, solution design, technology direction Do this each time architecture changes Execution / Build / Pilot Review (pre-release) Approve architecture /design changes that may occur during E&B
- 6. Cont.. Purchase process reviews Pre-purchase Review (RFP, IFB) Ensure sensible technical language in requirements Purchase Proposal Review (pre-award) Approve technology selections, architecture and strategy of proposal
- 7. Basic review flow Submit documents (project team) Review documents (architect) If issues are found: Resolve issues Re-submit If issues are not resolved: Approve with issue or Reject If rejected: Re-plan and resubmit or halt If approved with issue Track and resolve issue later on
- 8. Data Flow Diagram Of Architecture Review Author Moderator Reviewers Y N DESIGN REVIEW Prepare work products and plan Ready for review ? Examine work products Read package Study work products Prepare comments Schedule review send out packages Prepare review package
- 9. Work Product & Plan Work products (design) use cases class diagrams primary responsibility of each class sequence diagrams models etc. Plan what will be reviewed and the order what types of issues will be covered don’t hide risks
- 10. Review Package Intro- history, key problems, important decisions, requirements, designs, analysis etc Agenda- Order materials will be reviewed Criteria- Define the various fields Work products- Use cases, class diagrams, sequence diagrams, etc Reviewer assignments- What each reviewer is responsible for; e.g. give each reviewer responsibility for a subset of the classes
- 11. Roles In Review Process • Moderator – not a member of reviewed team • keeps review moving • ensures all voices are heard and key points covered • ensures decisions are made: accepted, major/minor revisions, further review • Recorder – member of the reviewed team • takes notes, records all issues raised and decisions reached, all questions, suggestions, and action items • publishes a report of the review
- 12. Roles In Review Process • Reviewers • Raise questions, concerns • Author and design team • Answers questions but is otherwise silent
- 13. Benefits of Architecture Review Identifying potential risks in the proposed architecture Assessing quality attributes (for example, scalability, performance) Identifying opportunities for reuse of artifacts and components Promoting good architecture design and evaluation practices Reducing project cost caused by undetected design problems Capturing the rationale for important design decisions Uncovering problems and conflicts in requirements
- 14. • Conforming to organization’s quality assurance process • Assisting stakeholders in negotiating conflicting requirements • Partitioning architectural design responsibilities • Identifying skills required to implement the proposed architecture • Improving architecture documentation quality • Facilitating clear articulation of nonfunctional requirements • Opening new communication channels among stakeholders Benefits of Architecture Review
