Task Dependencies | Blocker Tracking & Critical Path
Track task dependencies with linking, blocker alerts, and critical path analysis. GitScrum visualizes dependencies and notifies when blockers resolve.
8 min read
Task dependencies determine project success. When dependencies are unclear, teams duplicate work, wait unnecessarily, or miss critical handoffs. GitScrum provides visual dependency tracking, automated blocker alerts, and workflow tools that keep tasks flowing in the right order.
The Dependency Problem
Unmanaged task dependencies cause:
- Blocked developers β Waiting for work that isn't prioritized
- Hidden blockers β Dependencies discovered during implementation
- Deadline misses β Critical paths not identified early
- Wasted effort β Working on tasks before prerequisites complete
- Integration failures β Dependent tasks built with different assumptions
- Sprint disruption β Mid-sprint blockers derailing commitments
GitScrum Dependency Tools

Understanding Dependency Types
Common Dependency Patterns
1. BLOCKING DEPENDENCIES
ββββββββββββββββββββββ
Task B cannot start until Task A completes
[Setup Database] ββblocksβββ [Build API Endpoints]
[Design Mockups] ββblocksβββ [Implement UI Components]
2. PARALLEL WORK
ββββββββββββββ
Tasks can proceed simultaneously
[Backend API] βββparallelβββ [Frontend Mockups]
Both can work using agreed contract
3. SHARED DEPENDENCIES
ββββββββββββββββββββ
Multiple tasks depend on one

Setting Up Dependency Tracking
Creating Task Links in GitScrum
Step 1: Identify Dependencies During Planning
During sprint planning:
- Review each task for prerequisites
- Ask: "What must be done before this can start?"
- Ask: "What does this task unblock?"
- Document answers in task descriptions
Step 2: Use Labels for Dependency Status
Create labels for dependency tracking:
Label System:
βββ blocked (red) - Waiting on another task
βββ blocking (orange) - Other tasks wait on this
βββ ready (green) - All dependencies met
βββ needs-review (yellow) - Dependency unclear
βββ external-dep (purple) - Depends on outside team
Step 3: Document Dependencies in Task Descriptions
Include in blocked tasks:
## Blocked By
- [Task #123: Setup Authentication Service]
- Expected completion: Wednesday
## Impact
- Cannot implement login flow without auth endpoints
- 3 story points blocked
## Workaround
- Using mock endpoints for UI development
- Will integrate when #123 completes
Step 4: Configure Notifications
Set up alerts:
- Notify when blocking tasks complete
- Alert if blocked tasks aren't progressing
- Remind teams of upcoming dependency deadlines
Dependency Visualization on Boards

Legend:

Filtering for Dependencies
Use GitScrum filters:
View Options:
βββ "Show blocked tasks" - See all waiting work
βββ "Show blocking tasks" - Identify priority items
βββ "Show my blocked tasks" - Personal blockers
βββ "Show unlocked tasks" - Ready to start
Daily Dependency Management
Standup Focus on Dependencies
During daily standup, address:
1. BLOCKER CHECK
βββββββββββββ
"Any tasks blocked since yesterday?"
"Any blockers resolved?"
2. BLOCKING TASKS STATUS
ββββββββββββββββββββββ
"What's the status of tasks blocking others?"
"Expected completion date still accurate?"
3. UPCOMING DEPENDENCIES
ββββββββββββββββββββββ
"What dependencies hit in next 2 days?"
"Are blocking tasks on track?"
Using Team Standup Feature
Configure GitScrum Team Standup:
Daily Questions:
βββ "What did you complete?" (identifies resolved blockers)
βββ "What are you working on?" (tracks blocking tasks)
βββ "Any blockers?" (surfaces new dependencies)
βββ "What will you unblock today?" (focus on team flow)
Critical Path Identification

Prioritizing Blocking Tasks
Order backlog by impact:
PRIORITY MATRIX
βββββββββββββββ
HIGH PRIORITY (Address First):
βββ Tasks blocking multiple items
βββ Tasks on critical path
βββ Tasks with approaching deadlines
βββ Tasks blocking other team members
MEDIUM PRIORITY:
βββ Tasks blocking one item
βββ Tasks with flexible deadlines
βββ Internal dependencies only
LOWER PRIORITY:
βββ No blocking relationships
βββ Can be reordered freely
