Microsoft Project: When Excel Stops Being Enough

| Rhonda Garvin |

Excel handles a huge share of real-world project management. However, the shift to a dedicated tool like Microsoft Project earns its place once a project’s size, dependencies or number of stakeholders breaks a clear threshold. Get there, and the right training makes the tool actually pay off, not just the licence.

Excel probably supports more projects across Australian businesses than any dedicated project management tool. For small teams, straightforward timelines and simple project plans, it’s often the fastest and most practical option available.

That’s hardly surprising. Most office workers spend a significant part of their week in Excel already. Research from UK’s Acuity Training found that the average office worker spends close to 20 hours a week using spreadsheets. Although this isn’t an Australian figure, whether you’re tracking budgets, forecasting sales or managing project tasks, Excel is often the tool that’s already open on your screen.

The problem isn’t that Excel suddenly stops working. The problem is that projects rarely stay simple.

A project that starts with one person and a handful of tasks can quickly grow into something much bigger. More people become involved. Deadlines start depending on other deadlines. Resources are shared across multiple projects. Different stakeholders want different reports. Before long, the spreadsheet that felt perfectly manageable starts demanding more effort than the project itself.

That’s often the point where teams begin asking whether they’ve outgrown Excel.

Research from the Project Management Institute (PMI) suggests that fewer than half of projects are considered clear successes. While there are many reasons projects struggle, one common challenge is trying to manage increasingly complex work with tools that were never designed for that level of coordination.

This blog isn’t about convincing you to abandon Excel. Quite the opposite. It’s about helping you recognise when Excel is still the right choice, when it might be holding your team back, and what a dedicated project management tool such as Microsoft Project can offer when you’ve reached that point.

Because moving to a new tool shouldn’t be driven by a shiny feature list. It should happen when the complexity of your projects genuinely justifies the change.

What Excel is genuinely good at

Give credit where it’s due. Excel remains the right choice when:

· One person owns the plan and knows it well enough to explain it from memory

· The timeline is short, and the team is small

· Tasks don’t depend heavily on each other finishing in sequence

· Everyone touching the plan already knows how to use it

Zero learning curve, already installed on every machine in the building, and completely sufficient for the majority of projects a lot of Australian teams run.

Microsoft Project tools for managing tasks, dependencies and resources

The point where spreadsheets start working against you

Growth changes the equation, and it changes it fast. Watch for these signals; they’re your cue to act, not a warning sign to worry about.

· The project needs multiple people to manage it

Once several people are updating tasks, schedules, risks and progress, maintaining a single version of the truth becomes harder than it should be.

· Dependencies are becoming difficult to track

One task slipping quietly wrecks three others downstream, and nobody notices until it’s too late.

· Different audiences need different views

Executives, project leads and team members all need different information, but you’re maintaining multiple reports manually.

· People are shared across multiple projects

Understanding who’s available, overloaded or under-utilised becomes increasingly difficult.  This can be where spreadsheets genuinely break down.

· One person becomes the single point of failure

If the main person maintaining the spreadsheet is unavailable, progress and visibility suffer.

Hit two or more of these, and you’ve earned the upgrade. This is progress, not a problem. If you’ve noticed your team scheduling more status meetings just to keep everyone aligned on where a project stands; that’s often this exact problem showing up in disguise – worth a look at our piece on meeting overload if that sounds familiar.

Recognise a few of these in your team right now?

What does a dedicated tool actually give you?

This is where the investment starts paying for itself immediately.

· Automatic dependency tracking.

The tool flags the knock-on effect before it becomes a crisis.

· Real-time multi-user collaboration.

Everyone works from the same plan, with updates visible as they happen.  It also puts an end to the endless trail of Final_v3 and Final_v4 and Final_v4_ReallyFinal.xlsx files that appear when teams are still emailing spreadsheets instead of working from a shared spreadsheet.

· Tailored reporting from one source of truth.

Build it once, view it a dozen different ways.

· Resource leveling across every project running at once.

See exactly who’s overloaded before it becomes a problem.

Microsoft Project training turns these features from theoretical benefits into daily habits your team actually uses. Our trainers often see the moment when a project manager discovers dependency tracking, resource levelling or reporting views that solve problems they’ve been battling manually for years.

Why can the shift be genuinely game-changing?

Done well, this isn’t a minor efficiency gain. It changes what your team can take on. Predictable delivery builds the client trust that wins repeat business. Full visibility across every project stops your best people from getting stretched thin unnoticed. And a team that can confidently deliver complex work is a team that can actually grow the business, not just keep pace with it.

The tool only pays off if your team is trained to use it

Buying the software is only part of the transition. The real value comes when people understand how to incorporate it into their day-to-day project work.

That’s why training matters. Features such as dependencies, baselines and resource management deliver the greatest benefit when teams understand not just where to click, but how to apply them to real projects.

We’ve seen a similar pattern with Microsoft Copilot adoption. Organisations invest in a powerful tool, but without the time and guidance needed to build confidence, many users only scratch the surface of what’s possible. The technology is there, but the value never fully materialises.

The same principle applies to Microsoft Project. Teams that move from Excel without training often find themselves using only a fraction of what the software can do. That’s not a problem with the tool; it’s simply a sign that people haven’t yet had the opportunity to learn the capabilities that make the biggest difference.

When training is built around the way your team actually plans and delivers work, the software becomes far more than a digital project schedule. It becomes a practical tool for improving visibility, coordination and decision-making across projects.

Get that part right, and the benefits tend to show up quickly. Teams spend less time maintaining plans and more time using them to make informed decisions.

Has Your Team Earned the Upgrade? Excel or Microsoft Project?

The best project management tool isn’t the one with the longest list of features. It’s the one that matches the complexity of the work you’re managing.

If you’re not sure where your team sits, these questions provide a simple reality check:

· Fewer than three people are actively managing the plan, and task dependencies are straightforward?

Excel is probably still the right tool. It’s familiar, flexible and more than capable of handling projects of this size.

· Dependencies are becoming harder to track, or different audiences/stakeholders need different views of the same project?

You’re approaching the point where a dedicated project management tool can save significant time and improve visibility.

·Multiple projects are competing for the same people and resources?

You’re firmly in Microsoft Project territory. Resource management, workload planning and cross-project visibility become difficult to manage effectively in a spreadsheet.

It’s all about putting the right tool to proper use.

Excel earns its place in plenty of projects, and there’s no reason to move off it before you need to. But once your team hits real complexity, upgrading to a dedicated tool is a genuine step forward, not an admission that something was broken.

Microsoft Project Training through CTO is delivered onsite or online across Brisbane, Melbourne, Canberra, Adelaide and Perth, built around how your team actually plans, not a generic course.

The key takeaway is simple: don’t move because a vendor, consultant or software licence tells you to. Move when your projects have become complex enough that a dedicated tool will genuinely make life easier for your team.
