Redesigned the platform to help legal professionals access all data in one AI base, making complex workflows faster and easier

Through this eDiscovery tool, MitiCorp helps legal firms in uncovering critical information within unstructured data and streamlining the document review process.

Key Outcome:
  • Search Improvement:
70% Increase search efficiency
  • User Satisfaction: Increased from 50→80%
THE PROBLEM

Thousands of unstructured files, tight legal deadlines, and no clear way to find critical evidence or work as a team.

A major law firm faced a high-stakes corruption case with 17,000+ multilingual emails under a fixed deadline, but the platform slowed them down with fragmented workflows and poor coordination.

Existing Search Page

1

Search was siloed

Search was separate from documents, forcing users to restart their workflow every time they needed to cross-reference attachments.
2

Tagging, filters invisible under pressure

Filters were hard to find and slowed down high-volume review.
3

No structure for team-based review

This wasn’t a one-person job, but the tool had no way to assign, track, or coordinate document review, forcing teams to manage everything externally.

Design Process

Every project requires different tweaks.
For this project, I adopted the Lean Inception design process at the client’s request.

Cross-Functional Alignment Through Lean Inception

At the start of every phase, I facilitated Lean Inception workshops to align the team on scope and direction. Working with product owners, stakeholders, managers, and development leads, I defined key user types and features and built an MVP canvas grounded in user needs, translating early research and stakeholder input into a shared, actionable product definition.

DESIGN APPROACH

Incremental Revamp in 6 Phases

I led the design strategy and execution across each phase, focusing on progressive improvement, user validation, and close collaboration with cross-functional teams.

Over the 18-month transformation, each phase was guided by a clear business objective, delivery timeline, feedback, technical constraints and outcomes. I balanced user needs, business goals, and real-world limitations through an iterative approach — moving from understanding the problem and uncovering insights to defining strategy, designing solutions, validating concepts, and supporting scalable delivery.

The approach followed 6 key stages:

Planning → Research & Discovery → Insights & Experience Strategy → Concept Development → Prototype Interaction Design → Validation & Iteration → Development Handoff & Design System → Continuous Design, Testing & Iteration

ALIGNING PROJECT AND BUSINESS GOALS

Project Goal

Design an intuitive, user-friendly eDiscovery web application that simplifies legal document review, enhances efficiency, and minimizes cognitive load for lawyers, enabling them to quickly extract insights and streamline their workflow.

Business Goals

  • Reduce document review time with advanced tools to speed up the legal process.
  • Design a user-friendly interface to increase adoption and retention.
  • Differentiate through innovative features to attract new clients.
USER RESEARCH

Diving deep to find problems

Heuristic/Accessibility Evaluation

I assessed the existing application against Jakob Nielsen’s heuristics and WCAG accessibility guidelines, screen by screen. Worked closely with the software team to understand the system’s underlying structure.
Findings were compiled into a detailed report shared with the company, giving everyone a validated evidence base to align on before any design decisions were made.

Journey Mapping and Site Map Analysis

Mapped how legal professionals move through a case from start to finish, then audited the existing IA against that flow.

SME and Stakeholder Interview

Given that lawyers have busy schedules and generating requirements quickly was a challenge, I streamlined the process by creating user and business questionnaires. These documents helped me gather valuable insights efficiently within a short time frame.
Additionally, I outlined key focus areas and documented the findings to ensure a smooth & effective process.

Personas

Synthesising insights from user interviews and usability sessions, I documented how legal professionals actually move through their work day and translated those observations into a persona. This gave the team a shared reference point for every design decision, keeping user needs visible throughout all 6 phases rather than getting lost in delivery pressure.

Usability Testing

To gain deeper insights, I conducted moderated usability testing across each phase using real-world legal scenarios. Findings were documented, synthesised, and reviewed with a 12-member cross-functional team to drive design improvements.

Key Findings

Information discovery challenges
Users struggled to find and interpret relevant documents due to unclear hierarchy and metadata structure.
Inconsistent UI patterns
Identified inconsistencies across buttons, pagination, checkboxes, and actions impacting usability.
Limited context visibility
Users lacked visibility into document history, comments, and applied tags, reducing confidence in decisions.
Tagging workflow friction
Additional steps and low discoverability made document tagging less efficient.
Scanning difficulties
Unclear column structure and information ordering slowed down document review.

USABILITY TESTING INSIGHTS

How will we measure the success?

Time on Task

Avg. time to locate a relevant document was ~ 35+ mins
Users were unable to locate the target document within the session.

User Satisfaction

Current satisfaction score measured was 50% covering ease of use, task confidence, and overall experience

DESIGN PRINCIPLES

What guided every call I made

Simplicity and Efficiency
  • Design a clean, intuitive interface that allows users to navigate large datasets and complete tasks quickly with minimal steps.
  • Prioritize powerful search tools and customizable views to streamline workflows.
Intuitive Navigation and Error Prevention
  • Ensure a logical, familiar interface that helps users easily locate and manage documents without a steep learning curve.
  • Minimize user errors through smart design, offering clear guidance and actionable feedback.
DESIGN – TEST – ITERATE – TEST…

Initial Explorations

FINAL MOCKUPS

Few Hi-fidelity Screens

Discover insights in your data

Search your case using single words or phrases, with results ranked by relevance and key documents highlighted using tags for easy identification.

Organize documents by importance and download them directly from your dataset.

Document Review

It helps users filter out irrelevant information and prioritize key evidence, enabling them to discover insights more quickly and meet tight deadlines with integrated features that streamline the review process.

Create Timeline

Build a timeline to visualize trends and events, allowing you to explore when a concept or combination of concepts emerges in the data.

Reading pane

Quick access to all original documents, files, and emails resulting from your combined concept searches.

Users can perform actions such as annotating, highlighting text, tagging for relevance, filtering results, adding comments, and sharing insights within their team.
