Our Story

When Expressworks was founded in 1984, “change management” hadn’t entered the business lexicon. Our founding partners needed a simple way to describe their growing business, so they asked their clients for input. Here’s what they said: “You don’t sell us products – you help us get things done.” More than thirty years later, that’s still what we do, putting clients on the express route to meaningful business improvements. And if there’s been a common thread through the thousands of projects we’ve managed, it has been change.

To survive and grow, businesses have to change. But change is not a nebulous concept to be feared or tolerated. Change can be defined, quantified, and executed proactively. Change can be managed, and that’s what we do best.

Our change consultants provide the industry experience, third-party insight, and proven methods to help companies cut through complexity and achieve specific, measurable outcomes. Other consultancies could say the same, but we believe it’s our personal commitment that makes us different. We amplify our expertise with a genuine commitment to every project and every client. In the end, true change occurs because the people involved have committed to do what it takes to make it happen.

In a hyper-competitive world, winning is dependent on planning, implementing and sustaining change that results in shared success. That’s what it means to “get things done.”

Our Commitment to Clients

Our commitment is reflected in how we serve our clients and how we relate to our fellow consultants. These principles are what make our work successful, our relationships enjoyable, and our firm unique.

We are financially responsible, committed to serving as good stewards of our client’s budget.
Eliminating bureaucracy in our organization helps us bring simpler, more effective solutions to our clients.
We work well with others – with clients, with competitors, and among ourselves – because the best results are derived from diverse viewpoints.
We strive for the right balance of competency and chemistry to build trust and mutual respect with our clients.
Our consultants spend less time speculating and more time executing, which distinguishes us from competitors and creates superior value for clients.
The industries and companies we serve are constantly evolving, thus we continually sharpen our skills to present customized, innovative solutions.
Not content to coast on yesterday’s achievements, we work hard to raise the bar on every project we undertake.

Our People

Every client project is unique, which is why we don’t (and you shouldn’t) hire consultants with matching resumes. Expressworks is a mosaic of more than 100 experts from diverse backgrounds, each with a different story to tell, yet bonded by a common vision, personal commitment and professional expertise. They come together in small, precision-built teams to provide exactly the knowledge and expertise our clients need to create change. 

The Expressworks network is multi-faceted, but our consultants do have some things in common: they’re great at what they do, they’re driven to succeed, and they know how to put a plan in motion. Our people aren’t just experienced in their fields, they’re technically savvy and adept at driving a project forward.

Through the years, we’ve learned that the working relationship between our clients and consultants is critical to overall satisfaction and success. So, just as our clients have a say in who they work with, our consultants get to choose which assignments they accept. It’s a policy of choice that ensures a good fit from the start, creates a stronger all-around effort and leads to better results in less time.

Our Methodology

An uncommon approach

It’s one thing to pontificate and propose impressive plans. It’s much harder to execute – to work with real people in the real world and deliver real change. That’s how we set ourselves apart. While the conceptual side of change is essential, it’s implementation that counts when your budget and reputation is on the line.

So how exactly do we make real change manageable?

We help you define the “what and why.” But more importantly, we show you “how.” We help you get your arms around the actual work of change, translating high-level strategy into concrete outcomes that make sense in your organization. We assign priorities and timetables, ensuring that the right work happens at the right time. And we set clearly defined, measurable goals, so we never mistake activity for achievement.

A proven methodology, customized to your needs

Words to live by: past performance is no guarantee of future success. We understand that every change initiative has different goals, involves different people, and must overcome different constraints. There’s no such thing as a one-size-fits-all solution. Like a veteran coach with a brand new team, we bring a time-tested philosophy and a defined set of fundamentals that we apply to your specific challenges.

It starts with clear leadership, aligning process execution with program governance. We help you assign the appropriate resources to the most essential work, and ensure appropriate engagement and approval processes.

Execution takes place through a decision-driven process – planned and delivered logically, sequentially, and systematically – to ensure the cart doesn’t come before the horse. Our structured methodology helps your organization get ready for the change, execute the right plan, and make possible the alternate future you’re striving for.

What is the measure of success? A change initiative is working when it:

  • Accomplishes the original business intent.
  • Achieves or exceeds ROI targets, on-time, within budget.
  • Aligns behaviors and actions to business results.
  • Delivers high value to customers and satisfaction to employees.
  • Develops the capacity to adapt more quickly to future changes.
  • Creates an appetite for higher achievement—success breeds success.
  • Strengthens the organization’s effectiveness and competitive position.

Why Choose Us

We know we’re not the only change management consulting game in town. You have choices – good ones – for which firm you hire. And the truth is, Expressworks isn’t necessarily the perfect fit for every type of consulting project you can imagine (ever heard the phrase “jack of all trades, master of none?”). We specialize in change implementation, and yes, we are masters at that. Ask us why Expressworks might be right for your change initiative, and here’s what else we’d say.

2014 marked Expressworks’ 30th anniversary. Surprised? In that time we’ve led thousands of projects for dozens of major companies on six continents.
It’s not just our company name that’s seasoned. We take pride in hiring only consultants with significant industry experience and the success stories to prove it. For our clients, that amounts to “know-how to avoid rookie mistakes and get the job done right.”

It’s part of our culture to be forward-thinking and technically savvy. We know that connecting with the digital world isn’t about chasing the latest fad; it’s about knowing which technologies will deliver the results that matter.

We’re big enough to do this work and small enough to care deeply about it being successful.
