ACCA3 Academy

Formerly Athens Peak Academy and why the name changed

Peak Academy’s genesis story starts in Denver, Colorado.  The City of Denver implemented this lean government program in 2011 by Denver Mayor, Michael B. Hancock, who placed the team in the Department of Finance under the budget director.  Denver Peak Academy is a process improvement team that trains and collaborates with government employees to improve the customer and employee experience.  The program was designed to provide frontline employees with the tools to innovate and make data driven decisions.  

In November 2016, Tim Moreland, the director of performance management and open data for the city of Chattanooga, Tennessee, traveled to Denver to attend the city’s “Peak Academy” week-long training.  This program was designed to empower City of Denver employees to create and implement their own improvements to the way their government works. The experience convinced Tim that the program could work in Chattanooga, too. So three months later, with no budget and no staff, Moreland helped Chattanooga launch a Peak Academy of its own.  

Catherine Bennett sought out Tim Moreland to discuss how this program could be successfully delivered to ACCGov.  In April 2019, Tim Moreland came to Athens to deliver the first Athens Peak Academy and to teach Organizational Development how to facilitate the training.  The program suffered a slow start and minimal adoption, despite the excitement of its graduates to immediately implement A3 Thinking

So, what is A3 Thinking and why is it important?  

It starts with the A3 Report.  The training provides a simple and strict procedure that guides problem-solving by workers. The approach typically uses a single sheet of A3-size paper, which is the source of its name.  The A3 Report is a powerful tool.  It provides a concrete structure to implement PDCA Management.  It helps draw the report author(s) to a deeper understanding of the problem or opportunity and how to address it.  It facilitates cohesion and alignment within the organization as to the best course of action.  But as with any tool, one must know how to use it.

The power of the A3 report, however, derives not from the report itself, but rather from the development of the culture and mindset required for the implementation of the A3 system. In other words, A3 reports are not just an end product but are evidence of a powerful set of dynamics that is referred to as A3 Thinking.  


Repackaging and Rebranding ACCA3 Academy

In 2020, Organizational Development decided to offer the program again, with improved content and materials, and repackaged to reflect ACCGov’s mission and values.  We renamed the program ACCA3 because it our intention to help ACCGov become a lean government using deeply innovative practices and A3 Thinking. 

And then it happened.  Just two months before the already-scheduled course date.  COVID-19, social distancing, and the government shutdown.

Now, more than ever, new ways of thinking and new practices are needed to stretch our resources further without a reduction in the valuable services our citizens have come to rely on to feel both physically and psychologically safe.  Welcome to the new normal...and ACCA3 Academy.  Just in time to teach you lean government practices for tough times.


The Japanese art of repairing broken pottery with gold lacquer. Yep. That is a thing.  Once remade, it’s more valuable than it was to start with.  Just because something is broken or no longer serves its original purpose does not have to mean it has no more use.  Looked at thoughtfully, creatively, and identifying what would make it work better than before is the premise of ACCA3.

Maybe it's time to break things, so that they can be remade into something more unique and of greater value.  Sign up for ACCA3 today!

Peak Performance: How Denver's Peak Academy is Saving Money, Boosting Morale and Just Maybe Changing the World. (And How You Can, Too!)

When Denver Mayor Michael Hancock took office in 2011, he inherited an $80 million budget shortfall and a government workforce that had been through multiple rounds of cuts and furloughs. Morale was low. He needed a way to drive greater efficiencies, cost savings and improved performance—and he had to do it in-house, on a shoe-string budget.

Enter Peak Academy, the coaching and innovation program Mayor Hancock created to teach frontline city employees how to tackle small problems and deliver big results. In four years, Peak Academy trained 5,000 government staff in the fundamentals of lean manufacturing and other process management techniques. More than 2,000 employee-driven innovations later, the program had saved Denver an estimated $15 million. Word got out and dozens of other governments sent their staffs to Denver or hired Peak Academy to bring the training to them. 

In this fun, easy-to-read guide, Peak Academy director Brian Elms and Governing staff writer J.B. Wogan deliver the basics for the rest of us, with a surprisingly frank discussion about how hard it was to get the program off the ground. Experience a thoughtful exploration of both the challenges faced and the reasons why Peak ultimately succeeded. Get a clear overview of Peak Academy training methods and tools (including yes, all those yellow stickies).

See cncrete examples of employee-driven innovations—many of which sound, in hind-sight, like $40,000 no-brainers, until you realize there are hundreds of similar and much-needed fixes in every workplace. Peak Performance is a book that will help public sector leaders replicate the Peak model. It’s a book for government managers to read and talk about with their teams. But most importantly, it’s a book for anyone working in government at any level—about the power of good ideas to improve the way government works.


This video demonstrates how the Denver Department of Excise and Licenses improved their process using the A3 document.

This video was developed by the Washington State Department of Revenue Lean Transformation Office and Taxpayer Services Communications and generously shared with other state agencies to help spread Lean culture across government. The state of Washington's employees and leaders are learning to adapt Lean strategy, thinking and tools to state government operations so that they can deliver more value to Washingtonians for generations to come and make public service a deeply gratifying experience. This video provides an initial introduction to Lean thinking and principles for Washington State employees - explaining what Lean is, how Lean works, waste in the office, flow, Lean versus traditional management, and the history of Lean.
