Real-World IT Analyst Engagements

Each engagement below demonstrates how our IT Analyst consultants have delivered measurable outcomes for major organisations through disciplined systems analysis and requirements engineering.

Systems Analysis for Global ERP Migration

Energy | Shell

Shell embarked on a multi-year programme to consolidate seven legacy ERP instances into a single SAP S/4HANA platform spanning upstream, downstream, and trading operations across Europe and Asia-Pacific. The programme required comprehensive systems analysis to understand existing data structures, business rules, and integration points before any migration could begin.

Our IT Analyst led the analysis workstream for the downstream retail division, covering 340 retail sites across the United Kingdom and the Netherlands. The work involved mapping current-state processes in ARIS, documenting over 480 functional requirements across finance, supply chain, and customer management modules, and conducting fit-gap analysis against the target SAP configuration. The analyst also coordinated with Shell's enterprise architecture team to ensure alignment with the global template whilst accommodating regional regulatory requirements.

A significant challenge was reconciling conflicting business rules between the Dutch and British operations, particularly around fuel duty reporting and environmental compliance. The analyst developed a requirements traceability matrix linking each business rule to its regulatory source, enabling the solution architects to design configurable rule engines rather than hard-coded exceptions.

480 functional requirements documented with full traceability
340 retail sites mapped across two countries
30% reduction in anticipated data migration issues through early identification
Requirements accepted by global architecture board with zero rework

Requirements Gathering for Digital Health Platform

Healthcare | Nuffield Health

Nuffield Health sought to build a unified digital platform connecting its network of hospitals, fitness centres, and wellbeing services. The platform needed to provide patients and members with a single view of their health journey, from gym membership and fitness assessments through to clinical consultations and post-operative rehabilitation.

Our IT Analyst was embedded within the digital transformation team for nine months, leading requirements elicitation across five business units. This involved facilitating over 60 workshops with clinicians, fitness professionals, operations managers, and IT teams. The analyst produced detailed user stories with acceptance criteria, data dictionaries for clinical and fitness data, and interface specifications for integrating the new platform with existing systems including EMIS (clinical), Gladstone (fitness), and SAP (finance).

The most complex aspect was defining requirements for clinical data sharing between hospital and fitness environments, which required careful consideration of information governance, NHS Digital interoperability standards, and the Caldicott principles. The analyst worked closely with the information governance team to produce data flow diagrams that satisfied both clinical safety requirements and the organisation's ambitions for a seamless member experience.

320 user stories with acceptance criteria delivered
60+ stakeholder workshops facilitated across five business units
Full compliance with NHS Digital interoperability standards
Platform launched on schedule with 95% requirements coverage

Technical Documentation for HR Technology Transformation

Professional Services | CIPD

The Chartered Institute of Personnel and Development (CIPD) undertook a comprehensive transformation of its HR technology landscape to better serve its 160,000 members worldwide. The programme involved replacing legacy membership management, learning management, and events platforms with an integrated Salesforce-based ecosystem.

Our IT Analyst joined the programme during the discovery phase and was responsible for producing the complete technical documentation suite. This included current-state architecture documentation, target-state solution designs, data migration specifications, and integration specifications for 12 third-party systems. The analyst also documented the complex membership lifecycle, covering everything from student membership through to chartered fellowship, including the various qualification pathways and continuing professional development requirements.

A particular challenge was documenting the rules engine governing membership eligibility, which had evolved over decades and existed partly in system logic, partly in operational procedures, and partly in the institutional knowledge of long-serving staff. The analyst conducted extensive knowledge-capture sessions, producing decision trees and business rules catalogues that enabled the Salesforce development team to implement the logic accurately in the new platform.

Complete membership lifecycle documented across all pathways
160,000 member records successfully migrated using documented specifications
40% reduction in membership processing errors post-launch

Data Flow Mapping for Energy Trading Operations

Energy Trading | Shell

Shell's energy trading division required a thorough analysis of data flows across its trading, risk management, and settlement systems to support a regulatory compliance initiative driven by MiFID II and EMIR reporting obligations. The existing documentation was fragmented and out of date, creating risk for the organisation in demonstrating compliance to regulators.

Our IT Analyst undertook a systematic mapping exercise across 18 systems involved in the trade lifecycle, from front-office capture through middle-office risk management to back-office settlement and regulatory reporting. The work involved interviewing over 40 traders, risk analysts, operations staff, and IT support personnel to build a complete picture of how trade data flowed between systems, where manual interventions occurred, and which transformation rules were applied at each stage.

The analyst produced a comprehensive set of data flow diagrams using standard notation, supplemented by data dictionaries and transformation rules documentation. These artefacts were subsequently used by the compliance team to demonstrate to regulators that Shell had full visibility of its trade data lineage, and by the IT team to identify opportunities for automation and error reduction in the data pipeline.

Complete data lineage documentation for MiFID II compliance
23 manual intervention points identified for potential automation
Regulatory audit passed with no findings related to data flows

Integration Testing for Clinical Systems Upgrade

Healthcare | Nuffield Health

When Nuffield Health upgraded its clinical information systems across 31 hospitals, the organisation needed rigorous integration testing to ensure that patient data continued to flow correctly between clinical, administrative, and financial systems. Any disruption to these data flows could directly impact patient safety and care continuity.

Our IT Analyst designed and coordinated the integration testing programme, which covered interfaces between the upgraded EMIS clinical system, the Nuffield Health patient administration system, pharmacy dispensing, laboratory information management, and the PACS radiology imaging system. The analyst produced 280 test cases covering normal flows, exception handling, error recovery, and data quality validation scenarios.

The testing programme was structured in three phases. First, point-to-point interface testing validated each individual connection. Second, end-to-end scenario testing traced patient journeys across multiple systems. Third, regression testing confirmed that existing functionality remained intact after the upgrade. The analyst coordinated testing activities across clinical IT teams at all 31 hospital sites, maintaining a centralised defect log and producing daily status reports for the programme board.
