Reducing Context Switching for Developers
Context switching is the silent productivity killer in software development. Each interruption costs 15-30 minutes of recovery time, yet most developers switch contexts 20+ times per day. GitScrum provides tools and workflows to minimize interruptions, batch similar work, and protect the deep focus time that produces high-quality code.
The Context Switching Cost
Why task switching destroys productivity:
| Switch Type | Recovery Time | Hidden Costs |
|---|---|---|
| Slack message | 5-10 minutes | Mental thread lost, code flow broken |
| Meeting | 15-30 minutes | Requires mental reset, warm-up time |
| Different project | 20-45 minutes | Need to reload context, remember state |
| Bug vs. feature work | 10-20 minutes | Different mental modes required |
| Code review | 10-15 minutes | Must understand someone else's context |
| Production incident | 30-60 minutes | High stress, adrenaline, full reset needed |

├─────────────────────────────────────────────────────────────┤
│ │
│ Before starting work, verify: │

│ │
│ ☐ Dependencies resolved │
│ "Nothing external will block me" │

│ │
│ ☐ Task size is right │
│ "I can complete this in 1-2 focus sessions" │
│ │
│ IF ANY ☐ IS UNCHECKED: │
│ → Resolve before starting │

Best Practices
Do's
EFFECTIVE FOCUS PROTECTION:
✓ SINGLE-TASK BY DEFAULT
One active item, finish before starting new
✓ PROTECT MORNINGS
Creative work when energy is highest
✓ BATCH COMMUNICATION
Check at intervals, not continuously
✓ BLOCK CALENDAR
Focus time visible to others
✓ WRITE CONTEXT NOTES
Resume faster after interruptions
✓ SET EXPECTATIONS
Team knows your availability patterns
Don'ts
FOCUS-KILLING HABITS:
✗ ALWAYS AVAILABLE
Constant responsiveness = no deep work
✗ REACTIVE MODE
Responding to every notification immediately
✗ MULTITASKING
Switching between multiple active tasks
✗ UNCLEAR WORK
Starting tasks with unresolved questions
✗ MEETING FRAGMENTATION
Scattered meetings destroying focus blocks
✗ HERO CULTURE
Expecting instant response from others
