# Domain Pitfalls
|
|
|
|
**Domain:** Weekly Scheduler with Calendar Integration
|
|
**Researched:** Sat Jan 24 2026
|
|
|
|
## Critical Pitfalls
|
|
|
|
Mistakes that cause rewrites or major issues.
|
|
|
|
### Pitfall 1: Inconsistent Date/Time Handling
|
|
**What goes wrong:** Applications incorrectly handle time zones, daylight saving transitions, and date math, leading to tasks appearing on wrong days or times.
|
|
**Why it happens:** Complex timezone libraries are often misconfigured or developers don't understand the nuances of temporal calculations.
|
|
**Consequences:** Users lose trust in the system, tasks appear at wrong times, recurring events break.
|
|
**Prevention:** Use robust timezone libraries (like moment-timezone or Luxon), implement thorough testing for edge cases, clearly define time zones in user profiles.
|
|
**Detection:** Look for reports of tasks appearing on wrong days, time discrepancies, or recurrence issues, especially around DST transitions.
|
|
|
|
### Pitfall 2: Poor Event Conflict Resolution
|
|
**What goes wrong:** When multiple tasks are scheduled for the same time slot, the system doesn't handle conflicts gracefully.
|
|
**Why it happens:** Lack of proper conflict detection and resolution logic, or overly simplistic merging algorithms.
|
|
**Consequences:** Loss of task data, incorrect scheduling, and poor user experience.
|
|
**Prevention:** Implement clear conflict resolution rules (priority-based, user-selectable, etc.), provide visual indicators of conflicts in UI.
|
|
**Detection:** Monitor for user complaints about missing or duplicated tasks, unexpected scheduling changes.
|
|
|
|
### Pitfall 3: Inadequate Offline Support
|
|
**What goes wrong:** The application fails to function properly when offline or experiences network interruptions.
|
|
**Why it happens:** Ignoring offline capabilities during development or implementing flaky synchronization logic.
|
|
**Consequences:** User frustration, data loss during connectivity issues, reduced usability in unreliable environments.
|
|
**Prevention:** Implement robust offline-first architecture with local storage and intelligent sync strategies, design clear user feedback for connectivity issues.
|
|
**Detection:** User feedback about disappearing tasks, inability to create/edit tasks offline, or data inconsistencies after connectivity restoration.
|
|
|
|
### Pitfall 4: Calendar Integration Fragility
|
|
**What goes wrong:** Third-party calendar integrations (Google, Apple) fail or become broken due to API changes or permission issues.
|
|
**Why it happens:** Relying on unstable external APIs without proper error handling, insufficient testing across different calendar providers, ignoring breaking changes.
|
|
**Consequences:** Users lose ability to sync tasks, data inconsistency between systems, potential security issues.
|
|
**Prevention:** Implement proper error handling for API failures, use versioned API calls when available, design graceful degradation when integrations fail, maintain proper permission management.
|
|
**Detection:** Reports of sync failures, lost calendar events, or inability to connect to calendar services.
|
|
|
|
## Moderate Pitfalls
|
|
|
|
Mistakes that cause delays or technical debt.
|
|
|
|
### Pitfall 1: Overcomplicated UI for Simple Tasks
|
|
**What goes wrong:** The interface becomes cluttered with unnecessary options, making basic task management difficult.
|
|
**Why it happens:** Feature creep during development without continuous user feedback or design iteration.
|
|
**Consequences:** User confusion, increased learning curve, decreased adoption rates.
|
|
**Prevention:** Follow minimal viable product principles, conduct regular user testing, prioritize essential features.
|
|
**Detection:** User feedback indicating confusion, low engagement with core features, excessive time spent on simple operations.
|
|
|
|
### Pitfall 2: Inefficient Data Storage and Retrieval
|
|
**What goes wrong:** As the application grows, database queries become slow, affecting application responsiveness.
|
|
**Why it happens:** Poor schema design, lack of indexing, inefficient data structures for weekly views.
|
|
**Consequences:** Slow loading times, poor user experience, scalability issues.
|
|
**Prevention:** Design with performance in mind from the beginning, implement proper indexing, consider data partitioning for large datasets, optimize queries.
|
|
**Detection:** User complaints about slow performance, performance monitoring showing slow database queries.
|
|
|
|
### Pitfall 3: Inadequate Recurrence Logic
|
|
**What goes wrong:** Recurring tasks behave unexpectedly or fail to update properly.
|
|
**Why it happens:** Misunderstanding recurrence patterns, inadequate testing of edge cases.
|
|
**Consequences:** Users miss important recurring tasks, incorrect scheduling behavior.
|
|
**Prevention:** Implement comprehensive recurrence testing, validate user inputs for recurrence patterns, provide clear recurrence previews.
|
|
**Detection:** Reports of missed recurring tasks, incorrect recurrence behavior, user confusion about recurring event updates.
|
|
|
|
## Minor Pitfalls
|
|
|
|
Mistakes that cause annoyance but are fixable.
|
|
|
|
### Pitfall 1: Unclear Visual Indicators for Task Status
|
|
**What goes wrong:** Users struggle to distinguish between completed, upcoming, and overdue tasks visually.
|
|
**Why it happens:** Lack of consistent color coding or visual hierarchy in UI design.
|
|
**Consequences:** Reduced task awareness, difficulty scanning tasks quickly.
|
|
**Prevention:** Establish clear visual language for task states, maintain consistency across the interface.
|
|
**Detection:** User feedback about difficulty tracking task status, frequent requests for "mark as complete" functionality.
|
|
|
|
### Pitfall 2: Suboptimal Keyboard Navigation
|
|
**What goes wrong:** Application lacks keyboard shortcuts or intuitive keyboard navigation.
|
|
**Why it happens:** Focus on mouse-based interaction during development.
|
|
**Consequences:** Reduced productivity for power users, accessibility issues.
|
|
**Prevention:** Implement keyboard-friendly navigation, provide discoverable keyboard shortcuts.
|
|
**Detection:** User requests for keyboard shortcuts, accessibility compliance issues.
|
|
|
|
## Phase-Specific Warnings
|
