Exhibit 99.1

       Navigant Consulting Reschedules 2007 Investor Conference
         for October 22, 2007, and Moves up Its Third Quarter
                 Earnings Release to October 17, 2007


    CHICAGO--(BUSINESS WIRE)--Sept. 17, 2007--Navigant Consulting,
Inc. (NYSE:NCI), a global consulting firm providing dispute,
investigative, operational, risk management and financial advisory
solutions to legal counsel, government agencies and companies
experiencing regulatory or structural challenges, today announced that
it is rescheduling its 2007 Investor Conference. The conference, which
was scheduled to be held in Chicago on Thursday, September 20, 2007,
will now be held in Chicago on Monday, October 22, 2007. In addition,
the Company announced that its third quarter 2007 earnings would be
released on Wednesday, October 17, 2007. This is approximately one
week earlier than the previously announced release date of October 25,
2007.

    In making these changes William M. Goodyear, Chairman and CEO
stated:

    "I believe the Company has a number of new opportunities on the
horizon including those related to the sub-prime mortgage and housing
markets, on-going financial restatements and accounting
investigations, and product safety initiatives. At the same time,
certain softness in the Disputes and Investigations Practice, which I
have previously discussed, has continued.

    We are currently implementing several actions to better position
the Company for the remainder of 2007, and particularly for 2008 and
beyond. We have recently completed an assessment of our capabilities
in certain underperforming practices and are reducing our capacity in
these businesses. We have also begun a realignment of organizational
responsibilities and accountabilities to assure that our resources are
best deployed to address current market demands and opportunities, and
to ensure operational effectiveness. In addition, as a result of our
broad on-going efforts to more efficiently support the business, we
are adopting a more aggressive real estate management strategy. Taken
together, we believe these actions and opportunities will likely have
a material impact on our financial results for the third quarter and
full-year 2007.

    With this backdrop, it seemed sensible to reschedule our Investor
Conference to a time when we could discuss in detail these actions and
their anticipated impact. To facilitate this discussion we are moving
up the third quarter 2007 earnings release at which time we will also
provide new 2007 guidance."
