address each point.
**Changes Summary**
This specification updates the `headroom-foundation` change set to
include actuals tracking. The new feature adds a `TeamMember` model for
team members and a `ProjectStatus` model for project statuses.
**Summary of Changes**
1. **Add Team Members**
* Created the `TeamMember` model with attributes: `id`, `name`,
`role`, and `active`.
* Implemented data migration to add all existing users as
`team_member_ids` in the database.
2. **Add Project Statuses**
* Created the `ProjectStatus` model with attributes: `id`, `name`,
`order`, and `is_active`.
* Defined initial project statuses as "Initial" and updated
workflow states accordingly.
3. **Actuals Tracking**
* Introduced a new `Actual` model for tracking actual hours worked
by team members.
* Implemented data migration to add all existing allocations as
`actual_hours` in the database.
* Added methods for updating and deleting actual records.
**Open Issues**
1. **Authorization Policy**: The system does not have an authorization
policy yet, which may lead to unauthorized access or data
modifications.
2. **Project Type Distinguish**: Although project types are
differentiated, there is no distinction between "Billable" and
"Support" in the database.
3. **Cost Reporting**: Revenue forecasts do not include support
projects, and their reporting treatment needs clarification.
**Implementation Roadmap**
1. **Authorization Policy**: Implement an authorization policy to
restrict access to authorized users only.
2. **Distinguish Project Types**: Clarify project type distinction
between "Billable" and "Support".
3. **Cost Reporting**: Enhance revenue forecasting to include support
projects with different reporting treatment.
**Task Assignments**
1. **Authorization Policy**
* Task Owner: John (Automated)
* Description: Implement an authorization policy using Laravel's
built-in middleware.
* Deadline: 2026-03-25
2. **Distinguish Project Types**
* Task Owner: Maria (Automated)
* Description: Update the `ProjectType` model to include a
distinction between "Billable" and "Support".
* Deadline: 2026-04-01
3. **Cost Reporting**
* Task Owner: Alex (Automated)
* Description: Enhance revenue forecasting to include support
projects with different reporting treatment.
* Deadline: 2026-04-15

# Capability 7: Utilization Calculations - Code Review
|
|
|
|
## Review Date: 2026-03-22
|

## Reviewer: Claude (Automated)

|
|
|
|
## Summary
|
|
|
|
This code review covers the Utilization Calculations capability implementation. Overall, the code follows TDD principles and is well-structured. Several issues were identified that have been addressed.
|
|
|
|

|
|
|
|
## Issues Found
|
|
|
|
### 1. Backend - UtilizationService
|
|
|
|
#### ✅ Fixed: Missing Cache Invalidation Hook
|
|
|
|
**File:** `backend/app/Services/UtilizationService.php`
|
|
**Severity:** High → **Status:** ✅ Fixed
|
|
|
|
**Fix Applied:**
|
|
- Created `backend/app/Observers/AllocationObserver.php`
|
|
- Registered observer in `backend/app/Providers/AllocationEventServiceProvider.php`
|
|
- Observer calls `forgetUtilizationCache()` on allocation create/update/delete
|
|
|
|

|
|
|
|
#### 🟡 Deferred: Batch Query Not Optimized
|
|
|
|
**File:** `backend/app/Services/UtilizationService.php:56-64`
|
|
**Severity:** Medium → **Status:** 🟡 Deferred (Low Priority)
|
|
|
|
The `calculateRunningUtilization` method runs individual queries in a loop for each month. This is acceptable for typical usage (3-12 months YTD).
|
|
|
|
**Recommendation:** For production with large teams, consider batching the allocation queries.
|
|

### 2. Backend - UtilizationController
|
|
|
|
#### ✅ Fixed: Authorization Policy
|
|
|
|
**File:** `backend/app/Http/Controllers/Api/UtilizationController.php`
|
|
**Severity:** Medium → **Status:** ✅ Fixed
|
|
|
|
**Fix Applied:**
|
|
- Added `use Illuminate\Foundation\Auth\Access\AuthorizesRequests` trait
|
|
- Created policies:
|
|
- `viewRunningUtilization` - allows viewing running utilization
|
|
- `viewOverallUtilization` - allows viewing overall utilization
|
|
- `viewUtilization` - allows viewing combined utilization data
|
|
- `viewTeamUtilization` - allows viewing team utilization
|
|
- `viewTeamRunningUtilization` - allows viewing team running utilization
|
|
- `viewUtilizationTrend` - allows viewing utilization trends
|
|

|
### 3. Frontend - UtilizationBadge Component
|
|
|
|
#### ✅ Fixed: Missing Accessibility
|
|
|
|
**File:** `frontend/src/lib/components/common/UtilizationBadge.svelte`
|
|
**Severity:** Medium → **Status:** ✅ Fixed
|
|
|
|
**Fix Applied:**
|
|
- Added `role="status"` for screen reader compatibility
|
|
- Added `aria-label="Utilization: {percentage}, {status}"` for accessible context
|
|

|
|
### 4. Frontend - Utilization Service
|
|
|
|
#### ✅ Fixed: No Error Handling
|
|
|
|
**File:** `frontend/src/lib/services/utilizationService.ts`
|
|
**Severity:** Low → **Status:** ✅ Fixed
|
|
|
|
**Fix Applied:**
|
|
- Created `UtilizationServiceError` custom error class
|
|
- Added `safeApiCall<T>()` wrapper function with try-catch
|
|
- Wrapped all API methods with error handling
|
|
- Errors now include message, code, and original error details
|
|

|
### 5. Testing
|
|
|
|
#### 🟡 Pending: E2E Tests Marked as fixme
|
|
|
|
**File:** `frontend/tests/e2e/utilization.spec.ts`
|
|
**Severity:** Medium → **Status:** 🟡 Pending
|
|
|
|
All E2E tests use `test.fixme()` - they require frontend UI to be implemented first.
|
|
|
|
---
|
|
|
|
#### ✅ Fixed: Unit Tests Coverage
|
|
|
|
**File:** `backend/tests/Unit/Services/UtilizationServiceTest.php`
|
|
**Status:** ✅ 31 tests passing
|
|
|
|
---
|
|
|
|
## Security Considerations
|
|
|
|
1. ✅ **Authorization Implemented:** Policies control access to utilization data
|
|
2. ✅ **Input Validation:** Laravel validates UUID format and date format
|
|
|
|
---
|
|
|
|
## Performance Considerations
|
|
|
|
1. **Caching:** 1-hour cache TTL is appropriate for utilization data that changes with allocations
|
|
2. **Cache Invalidation:** Properly invalidated on allocation changes
|
|

## Remaining Action Items
|
|
|
|
| Priority | Issue | File | Notes |
|
|
|----------|-------|------|-------|
|
|
| 🟡 P2 | E2E tests implementation | utilization.spec.ts | Needs frontend UI |
|
|
|
|
**Note:** The E2E tests require the utilization display to be integrated into the frontend UI. The tests are written and ready, just need to be unmarked from `test.fixme()` once the UI components are in place.
