Scenario: Your team is working on a complex project with multiple dependencies between tasks. How can you use JIRA's issue linking feature to ensure that tasks are completed in the correct order?

Option 1: "Relate them using 'is blocked by' and 'blocks' issue link types" is the correct option. When managing a complex project with multiple dependencies between tasks in JIRA, using the "is blocked by" and "blocks" issue link types ensures that tasks are completed in the correct order. By establishing these linkages, you indicate which tasks must be finished before others can start, helping to maintain the project's logical sequence and ensuring smooth progress. This approach enhances clarity and coordination within the team, minimizing the risk of delays or conflicts arising from task dependencies.
