How to Reduce Context Switching for Developers
Context switching destroys developer productivity, with studies showing it takes 23 minutes to refocus after an interruption. GitScrum helps reduce context switching by centralizing work information, providing clear priorities, and enabling focused work sessions where developers can tackle one thing at a time without hunting for information.
Context Switching Impact
| Switch Frequency | Productivity Impact | Recovery Time |
|---|---|---|
| Every 10 min | -40% productivity | Constant loss |
| Every 30 min | -25% productivity | 15 min/switch |
| Every 2 hours | -10% productivity | 10 min/switch |
| Half-day blocks | Minimal impact | 5 min/switch |
Context Switching Reduction Strategies
SOURCES OF CONTEXT SWITCHING
1. WORK-IN-PROGRESS OVERLOAD
┌─────────────────────────────────────────────────┐
│ Problem: │
│ Developer assigned 5+ tasks simultaneously │
│ Jumping between unrelated work │
│ │
│ Solution: │
│ WIP limit: 1-2 tasks per developer │
│ Finish before starting new work │
│ Clear priority so only top item gets attention │
└─────────────────────────────────────────────────┘
2. INTERRUPT-DRIVEN WORK
┌─────────────────────────────────────────────────┐
│ Problem: │
│ Slack/Teams notifications every few minutes │
│ "Quick questions" that derail focus │
│ Support requests during deep work │
│ │
│ Solution: │
│ Defined office hours for interruptions │
│ Async-first communication culture │
│ Rotating "interrupt shield" person │
└─────────────────────────────────────────────────┘
3. MEETING FRAGMENTATION
┌─────────────────────────────────────────────────┐
│ Problem: │
│ Meetings scattered throughout day │
│ 30-60 minute gaps between meetings │
│ No protected focus time │
│ │
│ Solution: │
│ Cluster meetings (meeting days/hours) │
│ Protected focus blocks on calendar │
│ No-meeting days │
└─────────────────────────────────────────────────┘
WIP Limits in GitScrum
IMPLEMENTING WIP LIMITS
PERSONAL WIP:
┌─────────────────────────────────────────────────┐
│ Board View - My Tasks │
│ │
│ In Progress (Max: 2) │
│ ┌─────────────────────────────────────┐ │
│ │ [FEAT-234] Implement user search │ ◄ Focus │
│ │ [BUG-567] Fix login timeout │ ◄ Queue │
│ └─────────────────────────────────────┘ │
│ │
│ Ready (Max: 3) │
│ ┌─────────────────────────────────────┐ │
│ │ [FEAT-235] Add search filters │ │
│ │ [FEAT-236] Export search results │ │
│ │ [TECH-89] Update dependencies │ │
│ └─────────────────────────────────────┘ │
│ │
│ Rule: Finish In Progress before pulling Ready │
└─────────────────────────────────────────────────┘
TEAM WIP:
┌─────────────────────────────────────────────────┐
│ Team size: 5 developers │
│ Team WIP limit: 5-6 items in progress │
│ │
│ Columns: │
│ To Do │ In Progress │ Review │ Done │
│ No limit │ Max: 6 │ Max: 4 │ No limit │
│ │
│ When at limit: Help others complete work │
│ Before starting new work │
└─────────────────────────────────────────────────┘
Focus Time Patterns
DEVELOPER FOCUS TIME SCHEDULE
OPTION 1: FOCUS MORNINGS
┌─────────────────────────────────────────────────┐
│ 9:00 - 12:00 Deep work (no meetings) │
│ 12:00 - 13:00 Lunch │
│ 13:00 - 14:00 Standup + collaboration │
│ 14:00 - 17:00 Flexible (meetings OK) │
└─────────────────────────────────────────────────┘
OPTION 2: NO-MEETING DAYS
┌─────────────────────────────────────────────────┐
│ Mon: Deep work - no meetings │
│ Tue: Normal - meetings allowed │
│ Wed: Deep work - no meetings │
│ Thu: Normal - meetings allowed │
│ Fri: Deep work - no meetings │
└─────────────────────────────────────────────────┘
OPTION 3: MAKER SCHEDULE
┌─────────────────────────────────────────────────┐
│ AM: 4-hour focus block │
│ PM: 4-hour focus block │
│ Meetings: Only at block boundaries │
│ (10am, 2pm, or skip day entirely) │
└─────────────────────────────────────────────────┘
Task Design for Focus
CONTEXT-COMPLETE TASKS
INSTEAD OF:
┌─────────────────────────────────────────────────┐
│ Task: Fix user search │
│ Description: It's broken │
│ │
│ Developer must: │
│ ✗ Ask what's broken │
│ ✗ Find the code │
│ ✗ Research how it should work │
│ ✗ Multiple context switches to gather info │
└─────────────────────────────────────────────────┘
CREATE:
┌─────────────────────────────────────────────────┐
│ Task: Fix user search returning stale results │
│ │
│ Current Behavior: │
│ Search results don't update after user edit │
│ │
│ Expected Behavior: │
│ Results reflect changes immediately │
│ │
│ Technical Context: │
│ - Cache invalidation in search.service.ts │
│ - Related: UserService.update() at line 145 │
│ - Test: search.spec.ts has related tests │
│ │
│ Reproduction Steps: │
│ 1. Search for "john" │
│ 2. Edit john's name to "jonathan" │
│ 3. Search again - still shows "john" │
│ │
│ Acceptance Criteria: │
│ ☐ Search returns updated data │
│ ☐ Tests updated for cache behavior │
└─────────────────────────────────────────────────┘
Communication Batching
ASYNC COMMUNICATION PATTERNS
INSTEAD OF: TRY:
──────────────────────────────────────────────────
Instant notifications → Batched digest
Direct messages → Public channels
"Got a minute?" → Scheduled 1:1
Urgent everything → Defined urgency levels
Real-time collaboration → Async documentation
NOTIFICATION SETTINGS:
┌─────────────────────────────────────────────────┐
│ During focus time: │
│ • Slack: Do Not Disturb │
│ • Email: Check 2x/day max │
│ • GitScrum: Batch notifications │
│ • Calendar: Busy/focus status │
└─────────────────────────────────────────────────┘
Best Practices
- Enforce WIP limits at individual and team level
- Protect focus time in calendars
- Write complete tasks with all needed context
- Batch similar work together
- Use async communication by default
- Cluster meetings to preserve focus blocks
- Measure and share context switching data
- Respect focus as a team norm
Anti-Patterns
✗ Assigning 5+ tasks "so you have options"
✗ Expecting instant responses
✗ Meetings scattered throughout day
✗ No protected focus time
✗ Tasks missing necessary context
✗ Treating all requests as urgent
