It’s not always a “training issue”. Often, it’s the reality gap between a standard system and how your operation actually works.

The pattern I keep seeing

Over the last decade, I’ve watched a frustrating pattern repeat itself across manufacturing and operations teams:

A company invests heavily in an ERP or MES expecting visibility, automation, and control.

Then, months later:

Planners still build schedules in spreadsheets

Supervisors track exceptions on whiteboards

Teams export data to rebuild reports manually

“The real process” lives in email threads and workarounds

It’s not because people love Excel.

It’s because Excel is where reality still fits.

The real issue: the system doesn’t fully match your operation

Yes, adoption matters. But adoption isn’t magic.

If the system:

Forces your team into generic workflows

Doesn’t integrate cleanly with your ecosystem (ERP, MES, IoT, legacy equipment)

Can’t support key edge cases without painful workarounds

…then people will do what smart people do:

they’ll route around it.

In our manufacturing projects, we consistently see the same needs: centralized, real-time data, automation of repetitive tasks, and seamless integrations between ERP, MES, and other systems.

“Is it training?” Sometimes. But here are the 5 most common root causes

Reality gap (your process is unique)

Integration gaps

If data doesn’t flow between systems, teams rebuild it manually. Done calls out this risk directly: without smooth connections, you get silos, duplicates, and delays.

The last-mile problem

Your ERP/MES handles the “standard 80%”… but your biggest headaches live in the remaining 20%.

Low trust in data

If dashboards are wrong once, people stop looking. Then reporting returns to spreadsheets.

No real owner

Not IT. Not your implementation partner. A true internal owner who can prioritize, enforce, and improve.

The fix is rarely “buy another tool”

Most companies don’t need a new ERP. They need to make the one they already have actually fit their operational reality.

This is where custom software becomes the missing piece, not to replace existing systems, but to strengthen them. The goal: extend the capabilities of your current systems, connect tools seamlessly, and eliminate low-value manual tasks.

At Done, we take an approach grounded in operational reality: solutions designed around existing processes, from planning through to execution. In practice, this often means targeted, high-impact extensions. For example, a timesheet application directly integrated with NetSuite (Blue Memento), or custom planning tools that replace critical Excel files, often a major source of errors and lost time.

A practical 6-step playbook (the Done way: small steps, real traction)

1) Identify “Excel hotspots”

Pick 3 to 5 recurring spreadsheets and ask:

Why does this exist?

What decision/process depends on it?

What data is missing or delayed upstream?

2) Audit your current system usage

Not features. Outcomes.

What is truly used daily?

What is avoided?

Where are people double-entering data?

3) Fix one workflow end-to-end (fast win)

Choose one painful process where you can eliminate manual effort quickly, such as: 

Production planning adjustments

Supplier invoice flows into accounting

Quality inspections captured on mobile instead of paper

Technician/rep workflows connected to ops data

Quick wins restore trust and momentum.

4) Build the integration layer (connect the ecosystem
)

If you want visibility, you need flow:

ERP + MES + warehouse + equipment + field tools.

In most manufacturing environments we’ve seen, the real issue isn’t the ERP itself, it’s the lack of integration between systems.

How to Choose the Right Software for Your Manufacturing Operations

Why choosing the right software is essential in manufacturing. In today’s rapidly evolving industrial landscape, selecting the right software isn’t just a technical decision, it’s a true strategic advantage…

5) Add a focused custom extension (the missing puzzle piece)

This is where Done often plays: creating a simple tool that fits your process and connects back to the systems you already run.

Real examples from Done projects: Engrenages Sherbrooke moved “from Excel to automation” with Atlas to optimize labor scheduling, production planning, and visibility into future work and resource needs.

Tag unified critical data in a single secure interface and improved stolen vehicle recovery speed by 25–40%.

Blue Memento was created to modernize timesheets, with integrations to tools like NetSuite, Dynamics, Gmail/Google Calendar, Outlook, JIRA, Zoom and more, and it includes AI-driven assistance for organizing time.

6) Create a quarterly improvement rhythm

Your business changes.
Your software has to evolve too.

A simple cadence (every quarter):

Review pain points

Measure what improved

Prioritize the next “Excel hotspot”

Ship the next small step

What ROI actually looks like (when the reality gap closes)

When teams stop working around the system:

Fewer manual touches

Faster decisions

Better predictability

More reliable reporting

Less dependency on “that one spreadsheet person”

And the best part: you’re not starting from scratch.

You unlock the full value of the system you’ve already invested in. Companies that take a pragmatic approach to optimizing their existing systems see an average 40% reduction in manual work.

Conclusion

If your ERP/MES is “in place” but your operation is still running on spreadsheets, you likely don’t need a reinvestment.

You need:

  • The right integration points
  • A few targeted extensions
  • And a realistic adoption plan anchored in outcomes

The Done team, based in Laval, supports companies not only in Montreal, but across Quebec and throughout Canada, helping them do exactly that through custom software development and pragmatic digital transformation.
