Describe the full development cycle of a task — from setting it in the JIRA system to its deployment in the working environment.

The full development cycle of a task using JIRA and integrating into the work environment typically includes the following stages:

1. Task creation in JIRA

   • Creating a task with description, priority, and assigned performer.
   • Clarifying requirements and acceptance criteria.

2. Planning

   • Estimating effort.
   • Including the task in a sprint or work plan.

3. Development

   • Writing code according to requirements.
   • Local testing.

4. Code review

   • Submitting changes for review.
   • Fixing comments.

5. Testing

   • Running automated and/or manual tests.
   • Verifying compliance with requirements.

6. Build and deployment

   • Integrating changes into the main branch.
   • Building and deploying to a test or staging environment.

7. Acceptance testing

   • Checking the functionality in conditions close to real use.

8. Deployment into the production environment

   • Deploying to production.
   • Monitoring and support.

9. Closing the task in JIRA

   • Updating the task status.
   • Documenting results and lessons learned.

This process may vary depending on the development methodology (Agile, Scrum, Kanban) and project specifics.
