SDLC FLOW

One lifecycle, eleven checkpoints. Dedicated slides below explain the key stages in detail.

1. Grooming

Backlog refinement and sizing.

2. Brainstorming

Solution options and risks.

3. System Design

Architecture and module contracts.

4. Reviewing System Design

Cross-team quality and feasibility.

5. Dev (Development)

Implementation and integration.

6. Deploy to release/staging

Release candidate deployment.

7. QA Testing

Validation against requirements.

8. Fix Issues (Development)

Defect fixes and stabilization.

9. UAT / Stakeholder Validation

Business acceptance check.

10. Production Deployment

Go-live rollout.

11. Monitoring & Feedback

Operate, observe, improve.

Detailed focus: The next dedicated slides focus on Grooming, System Design & Review, and Development execution.

Quality loop: QA feedback still loops into fixes, then back to staging and retest.

SDLC process overview and key feedback loops
1

Grooming & Brainstorming

Developers, QA, and frontend align on PRD and Figma before implementation starts.

What Happens Inside

  • Read PRD and inspect Figma flow together to lock feature intent.
  • Break each page request into concrete tasks, for example list endpoint and create endpoint.
  • Check external dependencies and integration points needed to deliver the feature.
  • Decide whether existing endpoints can be reused, updated, or created as subtasks.

Outputs and Exit Criteria

  • Task list is complete with dependency status for each item.
  • Existing API reuse or update decision is documented.
  • Missing API creation is captured as subtask with owner and acceptance criteria.
  • Team has one shared understanding before design starts.

System Design & Review

After grooming, developers draft technical design and review choices together with technical writer support.

What Happens Inside

  • Create database schema updates, sequence diagrams, and module boundaries.
  • Describe API contracts, failure cases, and operational assumptions.
  • Collaborate with technical writer in parallel to keep design artifacts readable.
  • Run cross-team review to challenge feasibility, risk, and maintainability.

Outputs and Exit Criteria

  • Design package is approved with clear architecture choices.
  • Trade-offs and open risks are explicitly recorded.
  • Implementation sequence is clear for frontend, backend, and QA handoff.
  • Team alignment is complete before coding starts.

Development (Part 1)

Development starts in dedicated feature branches, then merges through pull requests into releases/development.

Branching and Implementation

  • Every developer works on a dedicated branch with naming convention like feat/inventory-list or feat/pelunasan-webhook.
  • Code is implemented from approved design while keeping commit history clear per feature scope.
  • When feature work is done, open a pull request to releases/development as the integration branch.
  • Run checks and reviews before merge to avoid instability in shared integration flow.

Promotion Path to QA

  • If one end-to-end happy flow is ready, promote build to releases/staging for QA testing.
  • Staging acts as release validation area before broader rollout decisions.
  • Any defects discovered in this path return to development for fixes and redeploy.

3B

Development (Part 2)

QA validation runs while feature work continues in parallel, with feature flags protecting risky flow changes.

Risk Control During Ongoing Development

  • If a change can impact existing user flows, gate it behind a feature flag.
  • Use explicit config naming, for example USE_CHECKOUT_CALCULATION_V2_IS_ENABLED=false or true.
  • Enable flags progressively after QA confidence is established.
  • Keep rollback simple by switching flag state when required.

Parallel Continuation and Team Cadence

  • While QA tests one delivered flow, developers continue remaining feature work in parallel.
  • Defects and enhancement findings are fed back quickly to active branches.
  • Team keeps delivery throughput high without blocking all development on one QA cycle.
  • Release confidence grows through repeated test, fix, and feature-flag control.

DAY TO DAY ACTIVITY - DEVELOPER WORKFLOW

Work from Jira Task -> Branch -> Code -> Done -> Add Proof and Comments

1. Go to Your Jira Task

Open assigned Jira task, read scope, and confirm acceptance criteria before coding.

2. Create a Branch

Create a branch in repository using naming convention, for example feature/INVC-1234-inventory-list.

3. Develop and Test

Implement changes, run tests locally, then commit and push with clear task-linked messages.

4. Mark Task Done

Set task as done when implementation is complete and open PR if required by team flow.

5. Add Comments and Proof

Add Jira comments and proof of work such as API response, test result, or UI screenshot.

Definition of done: code delivered, validated, and proof posted on the Jira task for visibility.

Use this as an execution checklist from assignment to reporting.

DAY TO DAY ACTIVITY - QA WORKFLOW

Test Feature → Send Proof to Jira Task  ·  If Bug Found → Create Issue → Fix → Verify → Send Proof Again

1. Pick What to Test

Open your assigned Jira task (Main Task or Subtask). Read the task details and focus on one feature at a time.

2. Identify Feature to Test

Read task details and acceptance criteria to understand the feature scope, objectives, and expected behavior.

3. Test the Feature

Execute test cases on the target environment. Verify list loads, filters work, pagination is correct, and data is accurate.

4. Evaluate Result

Working as expected → Done. Bug found → Follow the Bug Flow. Document actual vs expected behavior clearly.

5. Send Proof to Jira

Add comment on the same task with UI screenshot or API response, mention the feature tested, and update status if done.

Definition of done: feature validated, proof posted on the Jira task.  If a bug is found, create an issue and follow the Bug Flow below.

QA BUG FLOW

Create Issue → Developer Fixes → QA Verifies → Send Proof → Close Issue

B1. Create Bug / Issue

Create a bug in Jira with steps to reproduce, actual vs expected, environment, and screenshots or logs.

B2. Assign & Link

Assign to the related developer and link the bug to the original Main Task or Subtask and the feature tested.

B3. Developer Fix — Branch

Developer creates a branch (e.g. bug/INV-201-fix-null-filter), codes the fix, commits, pushes, and opens a PR.

B4. Proof of Fix (Dev)

Developer comments on the bug issue with what was fixed, how it was fixed, and screenshots or logs as evidence.

B5. QA Verify Fix (Retest)

QA retests the feature against original test cases, related scenarios, and regression paths to confirm the fix.

B6. QA Update Result

Fix verified → mark Done. Still an issue → re-open or comment with details. Loop back to B2 or create a new bug.

B7. QA Send Proof to Bug Issue

Add comment on the bug issue with what was retested, test results, screenshots or logs, and update status to Done.

B8. Close Issue

Close the bug issue after verification is confirmed. Issue is fix-verified and confirmed complete.

Still an issue after B6? Re-open or comment with details, then loop back to B2 or create a new bug ticket.
