Introduction
Purpose
The purpose of the Software Architecture Guidelines document is to provide a comprehensive and standardized framework for designing, implementing, and maintaining software architectures across all government institutions under the oversight of the Rwanda Information Society Authority. This document aims to ensure consistency, quality, and interoperability in software systems developed for government agencies. By establishing clear guidelines, this document aims to streamline software architecture decisions and enhance the overall efficiency, reliability, and security of government software solutions.
Scope
This document applies to all software development and architecture activities undertaken by or on behalf of government institutions under the oversight of the Rwanda Information Society Authority. It covers new software systems, major redesigns of existing systems, integration projects, and software procured from external vendors requiring customization. The guidelines encompass various deployment models including cloud-based and on-premises solutions, as well as different architectural patterns such as microservices, monolithic, and hybrid architectures.
These guidelines are mandatory for all government-funded software projects with budgets exceeding the threshold set by RISA, and are strongly recommended for smaller projects. Any exceptions require formal approval through the architectural review process outlined in Section 5 of this document.
Audience
This document is intended for various stakeholders within government agencies involved in the software development lifecycle. These include:
- Government IT Leaders: Responsible for overseeing software development initiatives, ensuring alignment with architectural standards, and promoting adherence to the guidelines.
- Software Architects: Responsible for designing the high-level structure and components of software systems in compliance with established architectural principles.
- Developers: Involved in implementing software systems based on the architectural designs and following the recommended technologies and practices.
- Project Managers: Responsible for project planning, execution, and ensuring that the architecture aligns with the guidelines.
- Quality Assurance and Compliance Teams: Responsible for verifying that software solutions meet the architectural and security standards set forth in the guidelines.
