Functional Requirements Functional requirements describe what the product should do, broken down into specific system behaviors and capabilities.
Non-Functional Requirements Non-functional requirements place constraints on how the product should do it and cover attributes like performance, security, scalability, reliability, and response time.
Business Requirements Business requirements represent organizational objectives and the "why" behind a project, focusing on desired outcomes like revenue increase or cost reduction.
Stakeholder Requirements Clear identification of who needs what and why, distinguishing between end users, sponsors, product owners, and internal teams.
Technical Requirements Specific constraints around infrastructure, technology stack, integrations, APIs, databases, and system dependencies.
Acceptance Criteria Conditions the product must satisfy to be accepted, which must be testable, concise, and completely understood by all team members.
Success Metrics Measurable indicators of whether the project achieved its goals (conversion rates, user adoption, performance benchmarks, etc.).
Constraints & Dependencies Budget, timeline, resource availability, regulatory compliance, third-party integrations, and external blockers.
Assumptions Documented beliefs about the environment, user behavior, technical feasibility, and market conditions that inform decisions.
Functional Decomposition Breaking down high-level functions into subfunctions, processes, and activities to the point where parts can't be broken down further.
Use Cases or User Flows Detailed scenarios showing step-by-step interactions between users and the system to accomplish goals.
Data Model How information flows through the system, what gets stored, what gets processed, and relationships between data entities.

- Scope
- Architecture
and
-
devcontainer.json - Configure your development environment with a devcontainer.json file that specifies the Linux OS, automatically installed tools/runtimes/frameworks, port forwarding, environment variables, editor settings, and extensions
-
Dockerfile (or use prebuilt images) - Define your container build either with a Dockerfile or reference prebuilt dev container images
-
.gitignore - Exclude files you don't want tracked in version control
-
README.md - Include instructions about environment requirements, dependencies, and allowed libraries for the project
-
Dependency/Build Files - package.json (Node), requirements.txt (Python), pom.xml (Java), etc.
-
postCreateCommand Configuration - Automate setup commands like npm install that run after the container builds
-
Port Forwarding Configuration - Define which ports need to be accessible for development/testing (e.g., 3000 for web apps, 9229 for debugging)
-
VS Code Extensions List - Specify extensions in devcontainer.json customizations so developers get the same tooling automatically
-
Environment Variables/Secrets Setup - Configure how sensitive data (tokens, API keys) will be handled in the codespace
-
Entry Point Documentation - Clear instructions on what commands to run first to get the app running (e.g., npm run dev)
