System architecture provides a detailed understanding and technical description of a system and determines the features and strategy that will shape its implementation. This engineering "blueprint" is the plan that allows efficient execution of the detailed design-and-build process.
A well-thought out architecture provides flexibility of operation and the ability to absorb future enhancements or modifications without sacrificing budgetary or delivery constraints. It can be derived from a detailed set of specifications or begin as a general concept that is fleshed out through discussion. In either scenario, it should address the following areas, as applicable:
- Conceptual Overview
- System Requirements
- Design Platform Strategy
- System Functional Specification
- Preliminary Mechanical Layout
- High Level Electrical Schematics
- High Level Software Flow Charts
- Preliminary Software Screen Layouts
- User Interface Description
- Facility Requirements
- List of Primary Components
- Design and Build Budgets
- System Prototype Schedule
- Risk Analysis
