What after the PRD?

Once you have a PRD in place, the next step is to transition from planning to execution. Here’s a typical roadmap:

Stakeholder Review & Sign-Off:
- Present the PRD to key stakeholders (product managers, engineers, UX/UI designers, compliance teams, etc.) to gather feedback and obtain formal approval.
Technical Design & Architecture:
- Develop a detailed technical design document that outlines system architecture, data models, API contracts, and infrastructure requirements.
- Define technology stacks for mobile (iOS/Android) and web applications.
Project Planning & Roadmapping:
- Break the project into phases or sprints (if using Agile methodologies).
- Establish timelines, milestones, and deliverables.
- Allocate resources and assign responsibilities.
Prototype & Wireframes:
- Create wireframes and mockups to visualize the user interface and user experience.
- Develop a minimum viable product (MVP) or prototype to validate concepts and gather early feedback.
Development & Testing:
- Begin development based on the technical design.
- Set up continuous integration/continuous deployment (CI/CD) pipelines.
- Establish testing protocols (unit, integration, security, and performance testing).
Regulatory & Compliance Checks:
- Work with legal and compliance teams to ensure that the product meets all necessary standards.
- Integrate and test third-party services (e.g., KYC, payment processing, AML/CTF APIs).
Iterative Feedback & Refinement:
- Use agile feedback loops to refine features based on testing and stakeholder input before full-scale rollout.

Each of these steps helps ensure that the project transitions smoothly from a requirements document to a well-designed, scalable, and secure product.

Technical Design & Architecture:

Developing a detailed technical design document is a multi-step process that involves collaboration among various teams (engineering, architecture, DevOps, security, etc.) and uses a range of tools and methodologies. Below is a step-by-step guide:

1. Define the Scope & Objectives

Purpose: Clearly articulate what the system should achieve and the problems it needs to solve.
Audience: Identify who will use the document (developers, architects, DevOps, QA, etc.).
Constraints: Note any budget, time, or technology restrictions.

2. Outline System Architecture

High-Level Overview:
- System Context Diagram: Illustrate how the app interacts with external systems (e.g., payment processors, KYC APIs, regulatory systems).
- Component Diagrams: Break down the system into components (frontend, backend, databases, third-party services) and show their interactions.
Design Patterns & Principles:
- Identify the architectural patterns (e.g., microservices, RESTful APIs) and design principles (e.g., scalability, modularity, fault tolerance).

3. Develop Data Models

Database Schemas:
- Create entity-relationship (ER) diagrams that detail tables, fields, and relationships.
- Define data types, primary/foreign keys, and indexing strategies.
Data Flow Diagrams:
- Illustrate how data moves through the system, from user input to storage, processing, and reporting.
Data Storage Decisions:
- Decide on relational vs. NoSQL databases based on data requirements, performance, and scalability.

4. Define API Contracts

API Specification:
- List all endpoints with details on methods (GET, POST, PUT, DELETE), parameters, request bodies, and expected responses.
- Use tools like Swagger/OpenAPI to create and maintain the API documentation.
Error Handling & Status Codes:
- Define how errors are managed and what HTTP status codes to use for various responses.
Security Considerations:
- Document authentication (OAuth, JWT tokens) and authorization mechanisms.
Versioning:
- Explain the versioning strategy to manage API changes over time.

5. Specify Infrastructure Requirements

Hosting & Deployment:
- Identify cloud providers (AWS, Azure, Google Cloud) or on-premise solutions.
- Describe the deployment architecture (load balancers, auto-scaling groups, container orchestration with Kubernetes, etc.).
Network Architecture:
- Detail network topology, including firewalls, VPNs, or VPC configurations.
Environment Setup:
- Outline different environments (development, testing, staging, production) and their configurations.
Monitoring & Logging:
- Specify tools for performance monitoring, logging, and alerting (e.g., Prometheus, ELK Stack).
Disaster Recovery & Backups:
- Define backup strategies, recovery point objectives (RPO), and recovery time objectives (RTO).

6. Include Security & Compliance Requirements

Data Protection:
- Describe encryption standards for data at rest and in transit.
Access Controls:
- Define role-based access control (RBAC) and multi-factor authentication (MFA) practices.
Regulatory Requirements:
- Document compliance needs such as GDPR, PCI-DSS, or specific financial regulations, and how the system addresses them.

7. Create Diagrams & Visual Documentation

UML Diagrams:
- Use Unified Modeling Language (UML) for class diagrams, sequence diagrams, and activity diagrams.
Flowcharts:
- Provide visual representations of processes (user registration, transaction processing, etc.).
Tools:
- Utilize diagramming tools like Lucidchart, Draw.io, or Visio to create and share visual documents.

8. Review, Validate, and Iterate

Peer Review:
- Share the draft document with key stakeholders (engineering, DevOps, security, compliance) for feedback.
Prototyping & Testing:
- Validate design decisions through prototypes or proof-of-concept implementations.
Updates:
- Iterate based on feedback and evolving requirements before final sign-off.

9. Documentation & Version Control

Central Repository:
- Store the document in a centralized location (e.g., Confluence, Git repository) to ensure version control.
Accessibility:
- Ensure that all stakeholders can easily access and update the document as needed.

By following these steps, you’ll create a comprehensive technical design document that acts as a blueprint for development. It serves as a reference point that details every aspect of your system’s architecture, from high-level components to detailed API contracts and infrastructure plans. This document is critical in guiding your development team, ensuring consistency, and minimizing miscommunication throughout the project lifecycle.
