Managing Task Dependencies Effectively

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 — Waiting for work that isn't prioritized
• Hidden blockers — Dependencies discovered during implementation
• Deadline misses — Critical paths not identified early
• Wasted effort — Working on tasks before prerequisites complete
• Integration failures — Dependent tasks built with different assumptions
• Sprint disruption — Mid-sprint blockers derailing commitments

Understanding Dependency Types

Common Dependency Patterns

1. BLOCKING DEPENDENCIES
   ──────────────────────
   Task B cannot start until Task A completes
   
   [Setup Database] ──blocks──→ [Build API Endpoints]
   [Design Mockups] ──blocks──→ [Implement UI Components]
   
2. PARALLEL WORK
   ──────────────
   Tasks can proceed simultaneously
   
   [Backend API] ←──parallel──→ [Frontend Mockups]
   Both can work using agreed contract
   
3. SHARED DEPENDENCIES
   ────────────────────
   Multiple tasks depend on one
   
                    ┌──→ [Feature A]
   [Core Library] ──┼──→ [Feature B]
                    └──→ [Feature C]
   
4. CHAIN DEPENDENCIES
   ───────────────────
   Sequential task flow
   
   [Research] → [Design] → [Implement] → [Test] → [Deploy]

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:
├── blocked          (red)    - Waiting on another task
├── blocking         (orange) - Other tasks wait on this
├── ready            (green)  - All dependencies met
├── needs-review     (yellow) - Dependency unclear
└── 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

Board Layout for Dependencies

SPRINT BOARD WITH DEPENDENCY VISIBILITY
═══════════════════════════════════════

 🔴 blocked       blocking        ready             ✓ done

                 [Task #34]       [Task #78]        [Task #23]
[Task #56]       in progress      ready             ✓ done
 🔴 blocked                                         unblocked #45
 by #34

Legend:
🔴 = blocked (red label)
🔓 = blocking other tasks (orange label)

Filtering for Dependencies

Use GitScrum filters:

View Options:
├── "Show blocked tasks" - See all waiting work
├── "Show blocking tasks" - Identify priority items
├── "Show my blocked tasks" - Personal blockers
└── "Show unlocked tasks" - Ready to start

Daily Dependency Management

Standup Focus on Dependencies

During daily standup, address:

1. BLOCKER CHECK
   ─────────────
   "Any tasks blocked since yesterday?"
   "Any blockers resolved?"
   
2. BLOCKING TASKS STATUS
   ──────────────────────
   "What's the status of tasks blocking others?"
   "Expected completion date still accurate?"
   
3. UPCOMING DEPENDENCIES
   ──────────────────────
   "What dependencies hit in next 2 days?"
   "Are blocking tasks on track?"

Using Team Standup Feature

Configure GitScrum Team Standup:

Daily Questions:
├── "What did you complete?" (identifies resolved blockers)
├── "What are you working on?" (tracks blocking tasks)
├── "Any blockers?" (surfaces new dependencies)
└── "What will you unblock today?" (focus on team flow)

Critical Path Identification

Finding High-Impact Dependencies

Identify critical path:

Prioritizing Blocking Tasks

Order backlog by impact:

PRIORITY MATRIX
═══════════════

HIGH PRIORITY (Address First):
├── Tasks blocking multiple items
├── Tasks on critical path
├── Tasks with approaching deadlines
└── Tasks blocking other team members

MEDIUM PRIORITY:
├── Tasks blocking one item
├── Tasks with flexible deadlines
└── Internal dependencies only

LOWER PRIORITY:
├── No blocking relationships
├── Can be reordered freely
└── Nice-to-have features

Handling Blocked Work

When Tasks Get Blocked

Immediate actions:

BLOCKED TASK PROTOCOL
═════════════════════

1. UPDATE STATUS
   ─────────────
   - Add "blocked" label
   - Document blocker in task
   - Note expected resolution

2. NOTIFY STAKEHOLDERS
   ────────────────────
   - Inform blocking task owner
   - Alert sprint/project lead
   - Update standup notes

3. FIND ALTERNATIVES
   ──────────────────
   - Can work proceed with mocks?
   - Is there parallel work available?
   - Can scope be reduced?

4. REASSIGN IF NEEDED
   ───────────────────
   - Move developer to non-blocked work
   - Pair program on blocking task
   - Get help to resolve faster

Reducing Block Time

Strategies to minimize waiting:

MINIMIZE BLOCK TIME
═══════════════════

1. PARALLEL WORK PATTERNS
   ───────────────────────
   - Use contract-first API development
   - Build with mock data/endpoints
   - Design UI before backend ready
   
2. SMALLER TASKS
   ──────────────
   - Break large blocking tasks
   - Deliver incremental value
   - Unblock sooner with partial work
   
3. COMMUNICATION
   ──────────────
   - Daily sync on blocking tasks
   - Share progress proactively
   - Flag delays immediately
   
4. EXPERTISE SHARING
   ──────────────────
   - Pair on blocking tasks
   - Document solutions for reuse
   - Cross-train to reduce bottlenecks

Automation for Dependencies

Automated Dependency Workflows

Set up GitScrum automations:

AUTOMATION RULES
════════════════

Rule 1: "Notify on Blocker Resolution"
───────────────────────────────────────
When: Task with "blocking" label → Done
Then: Notify subscribers of blocked tasks

Rule 2: "Alert Stale Blockers"
──────────────────────────────
When: Task with "blocked" label unchanged 3+ days
Then: Notify task owner and team lead

Rule 3: "Update Ready Status"
─────────────────────────────
When: All blocking tasks complete
Then: Add "ready" label, notify assignee

Preventing Dependency Problems

Proactive Dependency Management

During sprint planning:

DEPENDENCY PREVENTION CHECKLIST
═══════════════════════════════

□ Map all dependencies before sprint starts
□ Prioritize blocking tasks early in sprint
□ Assign blocking tasks to available developers
□ Build buffer time for critical path items
□ Identify fallback work for blocked developers
□ Document external dependencies and contacts
□ Set up notifications for key blockers
□ Review dependency status in sprint midpoint

Team Practices

Establish dependency awareness:

TEAM AGREEMENTS
═══════════════

1. Always document dependencies in task description
2. Add labels when blocking/blocked status changes
3. Raise blockers immediately in Slack/standup
4. Prioritize unblocking teammates over new work
5. Update expected completion when timelines shift
6. Review dependencies in sprint retrospectives

Common Anti-Patterns

What to Avoid

DEPENDENCY ANTI-PATTERNS
════════════════════════

✗ Hidden dependencies
  → Always document in task descriptions

✗ Verbal-only dependency communication
  → Record in GitScrum for visibility

✗ Ignoring blocked tasks
  → Address blockers daily

✗ Not updating status
  → Maintain accurate blocked/blocking labels

✗ Starting without checking dependencies
  → Review prerequisites before beginning

✗ No fallback plan for blocked work
  → Always have parallel tasks available
