Introduction
Omnia is Deloitte's cloud-based audit platform, used by its audit teams around the world to plan audits, analyse client data and document evidence, with a sister platform, Levvia, for smaller and less complex audits. One of the most painful parts of any audit, for both auditors and clients, is the "PBC" (prepared by client) request list: hundreds of requests for invoices, bank confirmations, contracts, reconciliations and explanations, often tracked in emails and spreadsheets. Late or incomplete responses push audits past deadlines and frustrate everyone. The task is to design a feature in Omnia that helps audit clients respond faster to auditor document requests. I'll clarify, explain why it matters, segment users, find pain points, and then propose, prioritise and measure a solution.
Omnia's exact client-facing features are not fully public. State your assumptions about what exists today, then design. Interviewers care more about your reasoning than about matching the internal product exactly.
Step 1
Clarify Questions (3 minutes)
- Why it matters: A CFO, a controller and an accounts clerk need different things.
- Hypothetical answer: The client's finance team at a mid-sized listed company: a financial controller coordinating, with 6–10 people in accounts payable, treasury, payroll and tax who upload documents.
- Impact: Design for coordination across many contributors.
- Why it matters: Avoid redesigning what works.
- Hypothetical answer (assumption): Omnia has a client portal where auditors post requests and clients upload files, but tracking, reminders and clarifications happen mostly over email.
- Impact: Focus on the workflow around requests, not file upload itself.
- Why it matters: Defines the outcome.
- Hypothetical answer: Fewer days from request to accepted evidence, and fewer requests sent back because the file is wrong or incomplete.
- Impact: Speed and first-time-right quality both matter.
- Why it matters: Audit is regulated.
- Hypothetical answer: Auditor independence rules mean the auditor cannot prepare client evidence; data security and retention rules are strict.
- Impact: AI can guide clients but must not create evidence for them.
Propose the Goal
Reduce the time and back-and-forth needed for audit clients to provide correct evidence, so audits finish on time with less stress for both the client's finance team and the Deloitte audit team.
Define the Scope
I'll design a "request workspace" inside Omnia's client portal for the client's controller and contributors during the year-end audit. Interim audits and auditor-only tools are out of scope.
Choose year-end, the busiest and most painful period, as the design moment. It makes the pain points concrete.
