About Us

Who we are

We worked together in Walmart Technology in the enterprise architecture and governance teams. Our tenures there varied from 6 years to 28.

What we do

We help companies that want to get more out of their IT by changing their Ways of Working.  We focus on the forefront of the IT Operating Model – enterprise architecture, service management, demand management, application portfolio management and IT governance.

What we have done

We were both thought leaders and change leaders for transforming Walmart’s IT Operating Model, transitioning from a project orientation to a product orientation.  We used a capability-based model to instill new behaviors for accountability to manage value, cost and risk. Within a year, Walmart Technology made significant improvements in maximizing value, optimizing cost and minimizing risk.


We applied a systems-thinking view as we designed the new operating model.  We incorporated other large initiatives already in flight, and we made them collectively more effective.  Those initiatives included moving from annual planning to continuous planning, adopting agile, and modernizing the technology portfolio.  


We think it’s safe to say we understand scale, complexity and results.

The Team

Tim Hale

  I am a Certified Enterprise Architect (Carnegie-Mellon University), an ITIL Expert, as well as a Certified Public Accountant. 


During my 27 years at Walmart Technology, I witnessed 4 different IT Operating Models. With Ken and Denver, we designed and led the fourth one to incorporate service management, business architecture, agile development and technology modernization. I’ve led the Architecture Management Office; I’ve designed and delivered an EA Training Program across 15 countries; and I’ve chaired the industry standards body for North American retail EDI standards 


I love designing approaches to sticky problems.  I strive to be keenly aware of what motivates people and their actions. I enjoy speaking across all levels of management and easily tailor my message to my audience. I’ve learned the importance of simplicity without being simplistic – the important things are always simple and the simple things are always hard.
