How I Helped a Legal Firm Increase Data Accuracy from 20% to 80%

How I Helped a Legal Firm Increase Data Accuracy from 20% to 80%.

1. Introduction: When Data Becomes a Liability

In the legal world, bad data is dangerous.

Wrong case numbers, outdated records, missing documents—these things don’t just slow you down. They cause mistakes, missed deadlines, and lost cases.

Legal work depends on clean, accurate data. Every contract, court date, and decision relies on it. When that data is wrong or incomplete, teams waste hours double-checking, fixing, or guessing. That’s time that could be spent on real legal work.

At a legal firm, one team faced a serious problem. Their data accuracy was just 20%.

That means 4 out of 5 records were wrong—missing fields, outdated info, or entered inconsistently across teams. The result? Confusion, manual rework, and growing risk.

They needed a fix. Fast.

This is how we turned it around—from 20% to 80% accuracy, with fewer errors, better control, and a system that actually helped people do their jobs.

2. The Root of the Problem

Before fixing the problem, we had to understand it.

The data issue wasn’t just about numbers. It was about everyday work breaking down.

Here’s what was happening:

  • Duplicate records: The same case entered twice under different names. No one knew which version was right.
  • Missed deadlines: Court dates, client follow-ups, and filing windows were slipping through the cracks because key details were buried or wrong.
  • Manual rework: Teams spent hours chasing missing data, correcting errors, and emailing back and forth to confirm facts.
  • Complaints: Internally, staff were frustrated. Externally, clients noticed delays and inconsistencies.

The root cause? Four different teams, each working in different ways, using manual processes and disconnected systems. Everyone was doing their best—but with no standard way to enter, update, or share data, chaos piled up fast.

And the cost?

  • Lost time: Skilled staff doing admin instead of legal work.
  • Lost trust: In data, in systems, and between teams.
  • Compliance risk: In law, one wrong record can mean a lost case or breach.

We weren’t just dealing with messy data. We were dealing with a system that couldn’t support the work it was meant to serve.

3. Diagnosing the Chaos

To fix the problem, we had to see it clearly.

We started with a full diagnosis across the four teams involved. Here’s how:

1. As-Is Process Mapping

We sat down with each team and mapped out what they actually did—not what was written in the handbook.
Every step. Every form. Every click.
We used BPMN to lay it all out visually, from data entry to final output.

2. Voice of the Customer

We ran interviews and feedback sessions with the people doing the work.
They told us what slowed them down, what confused them, and where errors always showed up.
This uncovered things no dashboard could: “We don’t trust the system,” “I copy and paste from old files,” “It’s easier to start over than fix it.”

3. Root Cause Analysis Workshops

We brought teams together—legal, admin, IT, and operations—to walk through real scenarios and find where things broke.
Using Lean Six Sigma tools like the 5 Whys and Fishbone Diagrams, we drilled down to the core issues.


What We Found

  • Fragmented systems: Each team used different tools that didn’t sync. Data had to be manually copied between them.
  • No data standards: Names, dates, and fields were entered in different formats—or skipped entirely.
  • Manual handovers: Instead of automatic updates, teams emailed spreadsheets or passed Word docs. Things got lost or edited out of sync.
  • No ownership: No one owned data quality. If something was wrong, it was always “someone else’s job.”

We weren’t just fixing a broken workflow—we were rebuilding the whole information pipeline.

4. Fixing the Flow: System and Process Overhaul

Once we understood the problem, we rebuilt the process—end to end.

Step 1: Choosing the Right System

First, we needed a system that worked for everyone.
We assessed options, tested use cases, and selected a new platform that could handle:

  • Centralised data entry
  • Role-based access
  • Real-time updates across teams

The goal was simple: one version of the truth, shared and trusted.

Step 2: Designing the To-Be Processes

We didn’t drop the new tool on top of the old mess.
Using BPMN, we mapped out clear, clean to-be processes—what the work should look like after fixing it.

We focused on:

  • Fewer steps
  • Clear roles
  • No duplication
  • Built-in quality checks

These new processes weren’t theoretical. They were built with the teams who’d use them—through collaborative design sessions that got real buy-in.

Step 3: Standardising Everything

Next, we defined data standards:

  • What’s required
  • What format it should be in
  • Who owns it
  • When it must be entered

We also added validations—so the system flagged errors before they became problems.

Tools We Used

  • Lean Six Sigma: To spot waste, reduce variation, and simplify.
  • BPMN: To document processes visually, step by step.
  • Workshops: To align people, not just systems.

This wasn’t just a tech upgrade. It was a full reset—clean workflows, shared systems, and consistent rules.

And it worked.

5. The Change Strategy: Winning Buy-In Across Teams

Fixing the process was one thing. Getting four different teams to adopt it? That was the real challenge.

Each team had its own habits, tools, and ways of working. We couldn’t just hand over a new system and expect instant success. So we built the change with them, not for them.


Co-Design Workshops

We brought all four teams into the room—legal, admin, operations, and tech.

Together, we:

  • Walked through current pain points
  • Designed the new workflows step-by-step
  • Agreed on what good looked like

When people help build the solution, they’re more likely to use it. That’s what these sessions achieved—alignment and ownership.


Clear Governance Roles

We defined who owns what—no more grey areas.

  • Who enters the data
  • Who checks it
  • Who approves it
  • Who maintains the process

Everyone knew their lane. That clarity alone solved half the issues we saw earlier.


Pilot Testing Before Full Launch

We didn’t roll out everything at once. We piloted with a small group first.
That let us test the process, adjust the system, and fix issues before going live company-wide.

Pilot feedback gave us credibility—it showed we listened and improved things in real time.


Training That Actually Helped

We skipped the boring manuals. Instead, we ran:

  • Live system walk-throughs
  • Shadowing sessions with early adopters
  • Q&A clinics where users brought real cases to test

People didn’t just learn the system—they learned how it made their work easier.


Change only sticks when it makes life better.
We proved that by involving the teams at every step—and making sure the system helped, not hindered.

6. The Results: From 20% to 80% Accuracy

The numbers speak for themselves.

1. Data Accuracy: 20% → 80%

Before the project, only 1 in 5 records was fully accurate.
After the fix, 4 out of 5 records were correct—first time, every time.

That shift transformed how teams worked.
Less checking. Less correcting. More doing.


2. Manual Work Eliminated: 5 FTE Saved

By automating data handovers and standardising entry, we eliminated the need for 5 full-time roles’ worth of admin.

That’s hundreds of hours every month—freed up for real legal work, not fixing forms.


3. Cycle Times Cut, Errors Reduced

  • Tasks that took days dropped to hours.
  • Fewer back-and-forth emails.
  • Clear steps meant fewer mistakes and faster turnaround.

As one project lead put it:

“It used to feel like we were chasing data. Now it just flows.”


4. Reporting That Works

Accurate, structured data meant reports were no longer guesswork.
Leaders could finally trust what they saw and act on it fast.


Bottom line?
Fewer delays. Better decisions. Less waste. More control.

And most importantly, a system that stayed clean—because it was built to be.

7. Beyond the Numbers: Cultural Shift in How Data Is Managed

The technical fix delivered results. But the real win was cultural.

Before the change, data was everyone’s problem—but no one’s job.
People waited for someone else to clean it up. Mistakes were expected.
Fixing errors was part of the daily grind.

After the change, that flipped.


1. Ownership Took Root

Each team had a clear role in keeping data clean.
People knew what they were responsible for—and took pride in doing it right.

“Now I don’t just enter data. I make sure it’s right. That’s my name on it.”
– Team member, post-rollout feedback


2. Accountability Became Normal

When errors happened, we didn’t just patch them.
We asked why, traced the root, and fixed the process—not just the symptom.

Everyone understood that clean data = less chaos.
That connection stuck.


3. From Fixing to Preventing

Before: teams wasted hours chasing bad inputs.
Now: the system flags issues before they spread.

The mindset shifted from “we’ll fix it later” to “we won’t let it break.”


This wasn’t just better data.
It was a better way of working—built to last.

8. Lessons You Can Apply

Want to fix your own data issues? Here’s what actually works—no theory, just hard-earned lessons:


1. Don’t Assume Software Will Fix Bad Processes

A new system won’t save you if the process underneath is broken.
Tech doesn’t solve confusion. It just makes it faster.

Fix the workflow first. Then automate.


2. Map Before You Automate

If you can’t draw your process on paper, don’t try to digitise it.

Process mapping shows you where waste lives, who owns what, and why things go wrong.
Only then should you hit “go” on a new tool.


3. Involve Users Early—Especially the Ones Doing the Work

The people doing the job know where the pain is.
Bring them into workshops. Let them design the solution with you.

If they build it, they’ll use it.


4. Set a Data Standard From Day One

Agree on what good data looks like—field by field.
Enforce it with rules, validation checks, and shared ownership.

Data quality isn’t a tech feature. It’s a habit.


No silver bullets. Just clear steps that build systems—and teams—that work.

9.Ready to Clean Up Your Data?

If you’re relying on spreadsheets, chasing errors, or second-guessing your reports—your data isn’t helping you. It’s holding you back.

Now’s the time to ask:

  • How accurate is your data—really?
  • How much time is lost fixing it?
  • Who owns data quality in your business?

If those answers aren’t clear, you’ve got hidden risk—and wasted effort.
