Case Study

The Challenge

A Metropolitan Borough Council faced significant operational challenges following the implementation of the Mosaic social care case management system. Social workers in Children’s Services encountered persistent data quality issues, usability frustrations, and inefficiencies, making daily tasks more difficult.

The process for requesting and implementing system changes was lengthy and resource-intensive, placing a heavy burden on Children’s Services and IT teams. The original implementation also failed to fully consider data and reporting needs, leading to poor visibility of key insights and a backlog of 60+ unresolved reporting requests in the Business Intelligence (BI) team.

Additionally, senior leadership was spending significant time and effort on problem management, diverting focus from strategic priorities. Recognising the need for a more structured and effective approach, the council engaged Perform Partners to provide expert Business Analysis support.

Our Approach

Our Change Squads was engaged to assess whether the Mosaic system met user requirements, to support the in-house Business Intelligence (BI) function, and to provide structure and clarity to the change management process. Our approach focused on four key areas:

• Gap Analysis: We conducted a comprehensive gap analysis to clearly articulate the challenges across services and systems. By consolidating insights from stakeholders, existing documentation, and system performance data, we were able to surface pain points and translate them into targeted improvement actions. This work laid the foundation for the overall change effort, aligning all subsequent recommendations under a unified understanding of what needed to change and why.
• System Functionality & Compliance: Critically assessed Mosaic’s suitability and compliance to regulatory and operational needs by evaluating internal commentary, reviewing prior analyses, and bringing clarity to existing backlog of improvement opportunities.
• Change Management & Process Improvement: Engaged around 25 key stakeholders across Children’s Services, IT, and Adult Social Care to assess and refine change workflows, introduced structured requirements gathering and best practices in change management to create a more controlled and effective system change process. As part of this, we developed a RACI model to clarify roles and responsibilities, improve communication, and strengthen decision-making within the change management process.
• Business Intelligence & Data Management: Worked with the BI team to refine reporting requirements, addressing ambiguity and ensuring clearer, more actionable definitions. Supported a shift towards simplifying outputs to accelerate the delivery of key data into operations.
• Strengthening Business Analysis Practices: Provided recommendations for enhancing Business Analysis (BA) capabilities, enhance governance, and align system changes with strategic objectives. This included targeted process analysis to identify and reduce waste and rework — enabling delivery teams to focus on high-value activities and ensure the right people were engaged at the right time.
