        JDA SOFTWARE ANNOUNCES PLAN TO BUY BACK UP TO TWO MILLION SHARES

SCOTTSDALE, ARIZ. - OCTOBER 25, 2000 - JDA(R) SOFTWARE GROUP, INC. (NASDAQ:
JDAS) today announced that its Board of Directors has authorized a repurchase of
up to two million shares of the Company's outstanding common stock. Under the
buy-back plan, the Company may periodically repurchase shares on the open market
at prevailing market prices or in privately negotiated transactions from time to
time over the next 12 months. JDA's management will make purchase decisions
based upon market conditions and other considerations.

         "We appreciate the support from our Board of Directors who believe that
JDA's shares are undervalued at the current price and do not reflect the value
of the Company's underlying assets, competitive position and current as well as
future prospects," commented KRIS MAGNUSON, SENIOR VICE PRESIDENT, CHIEF
FINANCIAL OFFICER. "With our excellent cash position, we can enhance shareholder
value by implementing this buy-back program without compromising our ability to
move forward with our growth plans."

         The repurchased shares will be held as treasury shares and used in part
to reduce the dilution from the company stock option plans and employee stock
purchase plans. JDA had 24,550,000 shares outstanding as of October 24, 2000.
