Modernising Singer’s Operational Workflow Platform

Client Overview

Singer operates a nationwide field-service and compliance operation integrated with Greentree. Over the years, their internal operational system had evolved into a large legacy PHP application with multiple disconnected workflows, duplicated logic, and heavily manual operational processes.

While the system had grown alongside the business, continuous feature additions over many years made the platform increasingly rigid, difficult to maintain, and challenging to scale.

Singer partnered with Structured for Success Ltd to modernise and stabilise the platform while preserving critical operational workflows and GreenTree integration.

The Challenge

1. Fragmented Workflow Logic

Different test types and operational modules handled workflows differently, creating inconsistencies across:

  • planned jobs
  • reactive jobs
  • remedials
  • technician actions
  • completion states

2. Rigid Legacy Architecture

The platform relied heavily on:

  • procedural PHP scripts
  • duplicated business rules
  • scattered status handling
  • module-specific workflow logic
  • tightly coupled UI and backend behaviour

This made even small operational changes risky and time-consuming.

3. Poor Workflow Visibility

Technicians and admins lacked centralized visibility into:

  • workflow approvals
  • remedial status
  • lifecycle state
  • reassignment requests
  • operational edge cases

4. Growing Operational Complexity

As the business expanded, the system needed to support:

  • more compliance workflows
  • more remedial handling
  • stronger audit tracking
  • safer lifecycle management
  • future scalability

without disrupting daily operations.

5. GreenTree Integration Risks

GreenTree import processing relied on legacy cron scripts and direct file/database handling, with limited operational visibility and error management.

Our Solution

We introduced shared workflow state management to replace scattered lifecycle rules across the system.

This centralized:

  • technician workflow visibility
  • Start Work lifecycle
  • read-only protection
  • planned/remedial overlap handling
  • completion rules
  • workflow state resolution

We built:

  • unified technician job boards
  • planned/reactive/remedial queues
  • workflow timelines
  • approval-based reassignment, reschedule, and reject flows
  • improved remedial visibility handling

A major improvement ensured technicians no longer lost access to unfinished jobs when remedial work was raised.

New admin tooling included:

  • workflow inboxes
  • lifecycle review dashboards
  • impersonation audit tracking
  • import issue visibility
  • month-end review and override controls

We modernized the GreenTree integration layer with:

  • structured import parsing
  • import logging
  • admin review workflows
  • assignment validation
  • operational issue tracking

while preserving business continuity with the legacy ERP processes.

Instead of continuing the legacy pattern of duplicated module logic, we introduced:

  • centralized test-type registries
  • shared remedial workflow handling
  • normalized lifecycle interpretation
  • controlled workflow services

creating a far more maintainable and scalable foundation.
