The challenge

Mitel CX is an exceptionally complex product: multiple communication channels, multiple roles — agent, supervisor, admin — and dense, high-stakes workflows all competing for the same space.

The work has been to take that complexity and make it simpler to use — without losing the depth the product needs.

Senior UX Designer, hired to lead the transformation of Mitel's CX platform. I own the UX direction across the whole arc.

Phase 1 Shipped

Transform

We rebuilt the platform from the ground up, including a full code rewrite, and reworked the UX so the core jobs are simpler to accomplish: less manual work, less complexity, and a cleaner UI throughout.

Phase 2 My initiative

Simplify

The rewrite removed a lot of complexity, but navigation and page count were still heavier than they needed to be. By analysing the real workflows and user flows, I identified where the structure could collapse, and proposed a simplified redesign now being built and rolled out.

The problem

The platform was organised around a data-driven approach to interaction status. In practice, different pages corresponded to different statuses of the same interaction: incoming → Queues, picked up → Inbox, resolved → History, grouped by case → Cases. The same information ended up stored in multiple places, and the interface was structured around status tags rather than the natural context of the support workflow.

The Problem diagram
The proposal

Shift CX to a user-centered model, where interactions are stored and handled the way an agent naturally would, rather than following rigid system codes. All interactions live in one unified area, with intuitive ways to search, navigate, and manage them.

The Solution diagram
What changes

A streamlined information architecture that brings everything together in one place. Fewer pages, less context-switching, and a cleaner, more intuitive structure that supports faster workflows.

What Changes IA diagram

Design moves

A single, unified Interactions page

A central place to access, organise, and act on every interaction — past, current, queued, or grouped by case. Powerful filtering and grouping replace the old jump between separate sections.

A clearer navigation menu

The side menu collapsed from twelve top-level items to seven, with CX Interactions now serving as a single entry point to the unified flow.

Menu comparison: 12 items reduced to 7
An improved Interaction View with a side detail pane

Agents can see participants, details, notes, related interactions, and suggestions alongside the main conversation — without ever leaving it. Less context-switching, the customer stays front and centre.

Phase 3 Current

Assist with AI

The current phase brings real AI assistance into the agent's workspace. I'm designing how it surfaces during live calls and inside written conversations, with one consistent assist layer across voice, chat, and email.

The problem

Agents handle high-stakes interactions in real time. They need help — context, suggested answers, signals about how a conversation is going — but anything that interrupts the call or buries the customer behind AI panels makes the job harder, not easier. The design question is how AI shows up without taking over.

Design moves

01
Live call transcription with sentiment analysis

The call is transcribed in real time and sentiment is surfaced alongside it, so the agent (and supervisor) can read the temperature of the conversation as it unfolds, not after the fact.

02
Live call assist

The assist layer reads the live transcript, connects it to the knowledge base, and offers the agent matching answers and suggested phrasing in the moment — turning "what do I say next" from a manual lookup into a supported decision.

03
Assist for chat and email

The same idea, applied to written channels: the assist reads the context of the conversation so far and helps the agent compose, respond, and reference the right information — one consistent AI layer across voice, chat, and email.

This phase is in active design. Specifics remain under NDA.
