Kendall Consulting Group was founded in 1992. The founders, Bob and Ginny Reck, had been working for CSC Index, a strategic consulting arm of Computer Sciences Corporation. CSC Index was targeting large reengineering engagements for large corporations, however, the basis for KCG was that the same approaches and methodologies could create similar results for smaller companies or divisions. This assumption turned out to be a good one and KCG was profitable and successful from the start, growing consistently through the 1990s. Kendall Consulting Group was named after the location in Cambridge, MA where most of the founders and initial staff had worked.

While at CSC Index (and its predecessors Index Group and Index Systems), the founders worked extensively with Mike Hammer and Jim Champy, individuals who wrote the book on business process reengineering in the 1990s. The Reck's had been using process redesign approaches since the mid-1980s in their consulting work, as well as a number of other approaches dealing with change management and technology deployment and strategies. They were ideally positioned when reengineering became a popular management tool in the early 1990s. Later, they worked extensively with Michael Treacy and Fred Wiersema, the founders of the Value Discipline concept. This relationship has enabled them to help many companies apply this important concept to their organizations.

KCG went further in reengineering than CSC Index in many ways. First, they devoted much greater attention to people in the business change process. This turned out to be a critical success factor (CSF) in leading to great results in their client engagements. Second, they had a strong understanding of information technology and what it could and couldn't do in the business sector. Third, KCG was quick to package their reengineering and change management methodology and successfully used it with several clients with whom they still maintain strong relationships. At the core of their approach was their capabilities to nurture, educate and coach that let them help their clients create their own business successes.

The Reck's had started several other consulting firms during their careers prior to 1992. In the early 1980s, they worked in Europe - taking American strategic consulting ideas to European clients. They started working there in 1983 and established the European consulting arm of Index Systems named Index International. This division grew and prospered dramatically during the European stay. By 1988, the office had over 40 staff and many strong client relationships. Further, the business had been a financial success from the outset. Their own work in Europe touched on well over 50 clients in fifteen European countries.

During the 1970s, Bob Reck had started an internal strategic planning consultancy for the organization he was working for. Several of that organization's clients heard about the internal effort and asked that he bring the tools and techniques he was using inside to them. Over the next three years, the dozen people in that endeavor created a highly successful consulting operation that helped the stature and revenue of that company.

In the past decade, building on work that started in the 1970s when he started an internal consulting group, Bob Reck was extensively involved in educating new hires for Index International and later CSC Index and KCG. Again, client companies with an interest in creating internal or external capabilities asked that the same expertise that was being developed inside be brought to them. KCG has worked with over a dozen companies to help them develop either an internal consulting capability where they want to be their own clients, or to add an external consulting capability to their products and services.

KCG had grown to over 24 people by the late 1990s when the founders changed their organizational model to one using of mostly contract staff. This let the firm maximize its flexibility and ability to deliver client value. CSC Index was being phased out by CSC, so many of its skilled consulting alumni were available in the independent contactor marketplace. Today, the KCG continues to function and prosper - delivering value to its clients in the United States, Europe and Asia. The company relocated to Florida in 1999.
