Comprehensive system for field operations management, survey collection, and tracking based on Backend-Plus.

language: also available in:

An advanced framework and application specialized in statistical field operation management, field roadmaps (Hdr), survey data collection, and quality control. Built on top of the Backend-Plus ecosystem and PostgreSQL, it is fully optimized for field deployment via an Offline-First/PWA architecture.

Main features are:

1. Field Operations & Roadmap Management (Hdr):
   • Dynamic assignment and allocation of workloads per zone, area, surveyor, and supervisor.
   • Real-time tracking of survey progress at the dwelling, household, and individual levels.
   • Visit logging, non-response reason tracking, re-entries, and supervisory escalation workflows.
2. Task Engine & Actions:
   • Allows modeling tasks, configuring available actions for each, and assembling an operational workflow around them.
   • Automated audit logs tracking user activity, timestamped transitions, and historical edits.
3. Centralized Metadata Architecture:
   • Allows questionnaire modeling driven by metadata, validating skip patterns and valid inclusions through the "meta-enc" metadata engine.
   • Consistency Engine & Validation Rules: Automated real-time or post-entry logical and range validation.
   • Permissions & Processes: Granular access control for views, tables, and operational actions based on field roles (Surveyor, Supervisor, Data Entry, Field Coordinator).
4. Offline-First Architecture (PWA) & Installer:
   • Seamless background installation and updates managed via Service Worker (swa).
   • Publicly served static assets, manifests, and App Shell (decoupled from session cookies) ensuring total application resilience in low/no-signal areas.
   • Floating installation log console and non-intrusive overlay for credential re-validation.
5. Advanced Grids & Survey UI:
   • Interactive, editable, filterable, and sortable data grids with native XLSX export support.
   • Responsive user interface optimized for mobile devices and desktop operation.
