Lead Business Analyst - Microsoft 365 Transformation

Salary: £50,000 £ 60,000

Remote - UK Only

Are you an experienced Business Analyst who has supported Microsoft 365 migrations or modern workplace transformation projects?

Can you engage with business users to understand how they actually use their technology, including the processes and dependencies that may not be documented?

Are you confident leading discovery, challenging assumptions and turning complex information into clear requirements?

We are recruiting for a growing technology consultancy delivering Microsoft, cloud, infrastructure and cybersecurity services. They are looking for a hands-on Lead Business Analyst to lead business discovery and requirements gathering in preparation for an anticipated major Microsoft technology migration.

The initial priority will be to understand how the business operates today. You will investigate how different teams use their applications, collaborate, manage documents and share information. This will include identifying business-critical processes, manual workarounds, application dependencies and access requirements that need to be understood before migration planning progresses.

You will work closely with client stakeholders, project managers, architects, consultants and engineers. You must understand Microsoft 365 well enough to ask informed questions, recognise potential business impacts and ensure technical decisions are supported by a clear understanding of operational needs.

Excellent communication will be essential. Business users may describe the same process differently, have competing priorities or struggle to explain what they need. You will bring structure to these conversations, challenge assumptions constructively and produce analysis that the business and technical teams can confidently use.

You will also guide a Business Analyst, coordinating analysis activities and reviewing deliverables while remaining directly involved in discovery and documentation.

• Plan and facilitate interviews and workshops with business users, process owners and technical specialists.
• Establish how different teams use Microsoft 365 and connected applications in their day-to-day work.

• Work with architects and engineers to ensure business dependencies inform migration planning.
• Coordinate analysis priorities and deliverables with the project manager and wider delivery team.
• Guide the Business Analyst and review outputs for accuracy, completeness and consistency.
