# Objective The purpose of this policy is to establish a clear, open, collaborative, and structured approach for developing Status features. By engaging key stakeholders from the outset and ensuring consistent involvement throughout the feature’s lifecycle, this policy aims to improve quality, reduce rework, and align deliverables with business goals. ```mermaid graph TD A[📜 Requirements Document - User Stories] subgraph DD [📃 Derivative Documents] B(✅ Acceptance Requirements) C(⚙️ Technical Specification) D(🎨 Designs) end A --> DD E[[💻 Implementation and Testing]] F[[🧪 QA and Design Review]] G[[🚀 Release]] DD --> E DD --> F E --> F F --> G ``` # Scope This policy applies to all feature development projects within the Status organisation and covers the entire lifecycle of a feature, from ideation to maintenance. # 🔑 Key Principles ## 📃 **Requirements-Driven Development** Every feature begins with clearly defined requirements. These requirements serve as the foundation for all subsequent documentation, design, development, and testing activities. ### **Requirements Document with User Stories** The **Requirements Document** serves as the foundation for each feature’s development. In the context of this process, user stories act as the primary way to define the requirements and communicate them across teams. By focusing on the actual needs of users, user stories provide a simple, iterative, and adaptable method of specifying and evolving requirements throughout the feature's lifecycle. ### **What is a Requirements Document?** In this process, the **Requirements Document** is composed of a set of **user stories**, which describe the desired outcomes from the user's perspective. ### User Story User stories follow a very simple format: - As `` - I want `` - so that `` See [About implementing user stories](https://www.notion.so/About-implementing-user-stories-fc6bc6b81e54461c85cd1b793cae4e22?pvs=21) This document also includes **acceptance criteria** and **other supporting documentation** such as designs and technical specifications to ensure clarity for the development, design, and QA teams. ### **Traceability to User Stories** - Every **acceptance requirement**, **technical specification**, and **design** should be traceable back to its corresponding **user story**. This ensures that the feature being built aligns with the original intention and delivers the desired value to the end user. ## 🦸🦹🧛 **The Three Amigos** A Three Amigos group is composed of a **developer**, **QA specialist**, and **designer**, responsible for a specific feature or set of features. Multiple Three Amigos groups may operate simultaneously, each focusing on different features or components of a project. The key roles in each group are: - **Developer**: Provides technical insights and feasibility assessments. - **Quality Assurance (QA)**: Ensures that the requirements are testable and aligned with quality standards. - **Designer**: Offers input on user experience and design considerations. The Three Amigos group assigned to a feature is responsible for providing input and context throughout the feature’s lifecycle. Each group works collaboratively to ensure their feature aligns with business goals and technical requirements. ```mermaid graph TD subgraph 3ag [🦸🦹🧛 Three Amigos] B[🧑💻 Developer] C[🧑🧪 QA Specialist] D[🧑🎨 Designer] B o--o E[[Provides technical insights and feasibility assessments]] C o--o F[[Ensures requirements are testable and aligned with quality standards]] D o--o G[[Gives input on user experience and design considerations]] end 3ag --> H[📦 Responsible for a specific feature or set of features] H --> I[🔄 Provides input throughout the feature’s lifecycle] H --> J[🎯 Ensures feature aligns with business goals and technical requirements] ``` ### Multiple groups - **Feature-specific**: Different features may require different combinations of developer, QA, and designer expertise. To accommodate this, multiple Three Amigos groups may operate concurrently, with each team focusing on specific features. This allows the organisation to scale development efforts and ensure that each feature receives focused attention from a dedicated team. - **Contextual understanding**: Each Three Amigos group is responsible for maintaining a deep understanding of their assigned features. By involving the same team throughout the lifecycle, there is continuity in knowledge, reducing the risk of miscommunication or misunderstandings as features progress. - **Cross-team collaboration**: If necessary, multiple Three Amigos groups can collaborate on interdependent features or provide support to each other. This ensures that all features are aligned with the overall product vision and technical roadmap. # ♻️ Feature Development Lifecycle Each feature follows a consistent, structured process with the involvement of the assigned Three Amigos group across the following phases: As required and/or reasonable the Three Amigos will consult with subject experts and the program lead for input. ```mermaid graph TD subgraph 3ag [👥 Three Amigos Group] X[💻 Developer] Y[🧪 QA Specialist] Z[🎨 Designer] end RM[🗺️ Roadmap] subgraph fdl [♻️ Feature Development Lifecycle] A[💭 Ideation] B[📜 Requirements Document - User Stories] subgraph DD [📃 Derivative Documents] C(✅ Acceptance Requirements) D(⚙️ Technical Specification) E(🎨 Designs) end DD --> G[🔍 Review and Testing] DD --> F[🏗️ Implementation] F --> G G --> H[🚀 Release] H --> I[🎛️ Feedback and Maintenance] end RM --> A A --> B B --> DD 3ag --o|Participates in| A 3ag --o|Owns or supports with| B 3ag --o|Participates in and gives context for| DD 3ag --o|Participates in and/or give context for| F 3ag --o|Participates in and/or give context for| G 3ag --o|Participates in and/or give context for| I ``` ## 1. 🗺️ **Roadmap to** 💭 **Ideation** - **Phase**: Roadmap - **Goal**: Identify key initiatives and high-level business objectives that will drive the creation of new features. - **Three Amigos Role**: The Three Amigos will use the Roadmap as the initial input to begin a feature lifecycle. - **Phase**: Ideation - **Goal**: During ideation, the Status team(s) collaborates to outline the goals and objectives of the feature. The assigned Three Amigos provide context and input on feasibility, design impact, and testing considerations. - **Three Amigos Role**: The Three Amigos group actively participates in this phase, consulting on technical, quality, and design concerns to shape the feature's initial concept. ## 2. 📜 **Requirements Definition** - **Phase**: Requirements Document - User Stories - **Goal**: - The assigned Three Amigos group formalises the feature’s requirements through **user stories,** ensuring they are clear, complete, and aligned with business goals and technical constraints. - These stories form the **Requirements Document** and serve as the foundation for subsequent documentation. - **Three Amigos Role**: The group either owns or supports the creation of user stories, contributing their expertise to ensure the requirements are testable, user-centric, and technically feasible. ## 3. 📃 **Derivative Documents: Design and Technical Specification** - **Phase**: Derivative Documents - **✅ Acceptance Requirements**: Defined based on the user stories, these provide the basis for validating the feature. - **⚙️ Technical Specification**: Created by the developer with input from QA and the designer, detailing the architecture and technical implementation plan. - **🎨 Designs**: Visual guidelines prepared by the designer, aligned with the user stories and technical constraints. - **Three Amigos Role**: The group participates in the creation and refinement of all derivative documents, providing context and ensuring they meet the overall objectives. ## 4. 🏗️ **Implementation** - **Phase**: Implementation - **Goal**: Developers begin coding the feature according to the technical specification, with QA preparing test plans based on the acceptance criteria, and the designer ensuring alignment with the designs. - **Three Amigos Role**: The group provides ongoing input throughout the implementation phase, ensuring that development proceeds according to plan and that technical, design, and testing standards are met. ## 5. 🔍 **Review and Testing** - **Phase**: Review and Testing - **Goal**: After implementation, the feature undergoes a thorough review. Testing is performed based on the acceptance criteria, with the QA specialist and the design reviewer verifying that the feature meets the required quality standards. - **Three Amigos Role**: The QA from The Three Amigos participate in the review process, ensuring that the feature aligns with the requirements, technical specifications, and design goals. ## 6. 🚀 **Release** - **Phase**: Release - **Goal**: Once testing is complete, the feature is prepared for release.
