Stabilising Legacy Systems: Driving Structured Documentation and Process Optimisation

Objective

To establish a structured business analysis and documentation framework at Focus Edumatics for a legacy online tutoring platform, improving system clarity, scalability, and delivery efficiency while supporting ongoing high-volume operations.

Strategy

Adopt an iterative documentation and process standardisation approach to stabilise a monolithic, poorly documented system, ensuring alignment between business needs and technology delivery without disrupting live operations.

Implementation

  • Identified critical challenges stemming from an 8-year-old legacy platform built reactively on ad hoc requirements, resulting in fragmented workflows, inconsistent feature usage, and lack of documentation.

  • Analysed system usage and operational workflows to uncover duplicate features, low adoption areas, and reliance on manual workarounds such as CSV-based data handling.

  • Introduced structured process mapping (current and future state) to visualise workflows, identify inefficiencies, and define standardised operating procedures.

  • Established formal requirements documentation practices, including business requirements, functional specifications, and acceptance criteria for all new and enhanced features.

  • Embedded documentation into the development lifecycle, ensuring that every feature release included clearly defined requirements, test scenarios, and validation criteria.

  • Standardised testing practices by defining test scenarios and test cases, improving quality assurance and reducing defects in production.

  • Developed and published knowledge base articles, FAQs, and demo videos alongside release notes to improve user understanding and reduce dependency on informal communication channels.

  • Implemented telemetry tracking to monitor feature adoption and system usage, enabling data-driven decisions on feature effectiveness and prioritisation. 

  • Continuously refined documentation and processes in parallel with ongoing system usage, ensuring minimal disruption to daily operations while progressively improving system structure.

Outcome

  • Improved overall system clarity and maintainability, enabling more efficient onboarding of new features and enhancements.

  • Reduced duplication, inconsistencies, and reliance on manual workarounds, leading to more streamlined operations.

  • Increased feature adoption and usability by aligning solutions more closely with actual user needs and behaviours.

  • Enabled data-driven product and process decisions through telemetry insights and usage tracking.

  • Established a scalable foundation for ongoing system optimisation and structured delivery, supporting high-volume operations without compromising performance.
