Why Planning Can't Live in Spreadsheets

Spreadsheets are everywhere — and for good reason.

They’re flexible, familiar, and available when other tools fall short. But spreadsheets aren’t a planning system.

They’re a workaround. Mosaic gives you the freedom of spreadsheets with the power of a purpose-built platform.

The Problem

Spreadsheets Are a Band-Aid for Broken Systems

Most teams don’t choose spreadsheets because they’re good at resource management.

They choose them because their software doesn’t work. You can’t schedule if you don’t know how much time you have, so spreadsheets become the de facto planning system - but without guardrails.

Spreadsheets become the bandaid because
  • ERPs aren’t built for planning
  • Project management tools don’t understand capacity
The result is predictable
  • Hundreds of tabs across dozens of spreadsheet files
  • Double data entry, stuck acting on outdated information
  • Disconnected teams and departments
  • No clear ownership or accountability
The Hidden Cost of Disconnected Data

The Answers Are Scattered - Where You Really Need Clarity

Managing your most critical resources—people and time—shouldn’t require piecing together data from five different sources.

But most firms spread the answers across:

  • The ERP (for financials)
  • Dozens of spreadsheets and hundreds of tabs
  • A project tool that doesn’t understand capacity
  • A BI dashboard on top try to make sense of it all

Mosaic brings it all together.
One system. One interface. One source of truth across the organization for people and projects.

Why This Matters

Spreadsheet’s Don’t Scale

As teams grow, spreadsheets become:

  • Fragile, with references breaking easily
  • Slow, with too many files and ‘sheets’
  • Error-prone with data you can’t trust

Resource management is mission-critical, so spreadsheets aren’t enough.

Mosaic Replaces Spreadsheets - Without Losing Flexibility

You shouldn’t have to choose between structure and speed. Mosaic gives you both.

Ready for Planning

Plan around actual capacity — not static rows and formulas.

  • Drag-and-drop planning across teams and projects
  • Adjust instantly as work changes
  • Model “what-if” scenarios without rebuilding files

Planning becomes continuous — not a monthly spreadsheet exercise.

Ready for Visibility

Move beyond siloed files and version confusion.

  • One shared source of truth for people and projects
  • See who’s working on what, now and next
  • No exports, no copying, no conflicting versions

Everyone plans from the same reality.

Ready for Forecasting

Spreadsheets give you data. Mosaic gives you answers.

  • Capacity vs. role demand forecasting
  • Hiring and pipeline scenarios
  • Utilization forecasting tied to real plans

Instead of reacting to problems, you see them coming.

Why Spreadsheets Can’t Do This

Spreadsheets:

  • Don’t stay current
  • Don’t track changes well
  • Don’t scale across teams
  • Overload people with rows and rework

They multiply complexity instead of managing it. Mosaic replaces ‘sheets’ with decisions.

What Changes

The Outcome

With Mosaic, teams move beyond spreadsheet chaos and achieve:

  • Clear visibility into who’s working on what
  • Balanced workloads that prevent burnout
  • Faster planning and forecasting
  • Higher utilization and stronger profitability
Why It Matters

The Bottom Line

Spreadsheets are a Swiss Army knife. They can do anything - but nothing well. If planning is critical to your business, you need more than rows and formulas.

You need a platform built for planning people and projects.

Plan better. Manage people better. Run the future with Mosaic.
