Engineering Fundamentals

This checklist helps to ensure that our projects meet our Engineering Fundamentals.

Source Control

• The default target branch is locked.

• Merges are done through PRs.

• PRs reference related work items.

• Commit history is consistent and commit messages are informative (what, why).

• Consistent branch naming conventions.

• Clear documentation of repository structure.

• Secrets are not part of the commit history or made public.

• Public repositories follow the OSS guidelines, see Required files in default branch for public repositories.

Work Item Tracking

• All items are tracked in AzDevOps (or similar).

• The board is organized (swim lanes, feature tags, technology tags).

Testing

• Unit tests cover the majority of all components (>90% if possible).

• Integration tests run to test the solution e2e.

CI/CD

• Project runs CI with automated build and test on each PR.

• Project uses CD to manage deployments to a replica environment before PRs are merged.

• Main branch is always shippable.

Security

• Access is only granted on an as-needed basis

• Secrets are stored in secured locations and not checked in to code

• Data is encrypted in transit (and if necessary at rest) and passwords are hashed

• Is the system split into logical segments with separation of concerns? This helps limiting security vulnerabilities.

Observability

• Significant business and functional events are tracked and related metrics collected.

• Application faults and errors are logged.

• Health of the system is monitored.

• The client and server side observability data can be differentiated.

• Logging configuration can be modified without code changes (eg: verbose mode).

• Incoming tracing context is propagated to allow for production issue debugging purposes.

• GDPR compliance is ensured regarding PII (Personally Identifiable Information).

Agile/Scrum

• Process Lead (fixed/rotating) runs the daily standup

• The agile process is clearly defined within team.

• The Dev Lead (+ PO/Others) are responsible for backlog management and refinement.

• A working agreement is established between team members and customer.

Design Reviews

• Process for conducting design reviews is included in the Working Agreement.

• Design reviews for each major component of the solution are carried out and documented, including alternatives.

• Stories and/or PRs link to the design document.

• Each user story includes a task for design review by default, which is assigned or removed during sprint planning.

• Project advisors are invited to design reviews or asked to give feedback to the design decisions captured in documentation.

• Discover all the reviews that the customer's processes require and plan for them.

• Clear non-functional requirements captured.

Code Reviews

• There is a clear agreement in the team as to function of code reviews.

• The team has a code review checklist or established process.

• A minimum number of reviewers (usually 2) for a PR merge is enforced by policy.

• Linters/Code Analyzers, unit tests and successful builds for PR merges are set up.

• There is a process to enforce a quick review turnaround.

Retrospectives

• Retrospectives are conducted each week/at the end of each sprint.

• The team identifies 1-3 proposed experiments to try each week/sprint to improve the process.

• Experiments have owners and are added to project backlog.

• The team conducts longer retrospective for Milestones and project completion.

Developer Experience (DevEx)

Developers on the team can:

• Build/Compile source to verify it is free of syntax errors and compiles.

• Execute all automated tests (unit, e2e, etc).

• Start/Launch end-to-end to simulate execution in a deployed environment.

• Attach a debugger to started solution or running automated tests, set breakpoints, step through code, and inspect variables.

• Automatically install dependencies by pressing F5 (or equivalent) in their IDE.

• Use local dev configuration values (i.e. .env, appsettings.development.json).
