¶ Technical Architecture
¶ What it is
Technical architecture is a form of IT architecture that is used to design digital systems. It involves the development of a technical blueprint with regard to the arrangement, interaction, and interdependence of all elements so that system-relevant requirements are met.
Detailed documentation will be provided, which includes the system overview, infrastructure design, key technical decisions, diagram of essential components, entity relationship diagram, etc.
¶ Why it is useful
Technical architecture is the very foundation of the system. It describes the system, including how it should be built and deployed. All the development team members should review and understand the architecture before any coding is started. Once the actual development begins, the architecture must be followed exactly to ensure the execution and the design are synchronised.
¶ When to use it
Once the main scope and IA are determined, the relevant architects (Front-end, back-end, etc.) should start to create the technical architecture. It should be done and aligned with the entire development team before the first dev sprint is started.
¶ How is it done
- Gather the project context and prerequisite as much as possible, including the project background, Information architecture, primary user flows, user roles, the current infrastructures, etc.
- Analyse the requirements and design the system's blueprint by considering the aspects of business, application, components, data flow, infrastructure, etc.
- Draw the diagrams (e.g., components diagram, data models) with necessary descriptions. Make sure it provides a good direction for developers to follow as a guideline.
¶ Do's & Don't
Do's
- Think about the whole lifecycle of the product but not just the production phase.
- Take the needs of other departments (business, operation, etc.) but focus on more than just the technical part.
Don't
- Do not focus on the details too much.
- Wait to start the concrete development before the relevant architecture is done.
