        PSDI APPOINTS DAVID SAMPLE AS PRESIDENT AND CHIEF EXECUTIVE OFFICER

CAMBRIDGE, MASS. -- February 5, 1997 -- The board of directors of Project
Software & Development, Inc. (NASDAQ:PSDI), a leading provider of maintenance
management software, announced today that David M. Sample, 48, is joining the
company as president and chief executive officer.

Sample joins PSDI after 11 years with Hyperion Software Corp. of Stamford, Conn.
(NASDAQ:HYSW), which International Data Corp. recently ranked first worldwide in
budgeting software revenue and third worldwide in client/server accounting
software revenue. Sample most recently served as senior vice president of
international operations and North American sales, helping to grow the business
to $173 million in fiscal 1996. During 1995, Sample served as head of Hyperion's
Pillar Software subsidiary. Previously, he headed Hyperion's UK business unit as
senior vice president and general manager. Prior to Hyperion, Sample spent eight
years with Ceridian Corporation (NYSE:CEN), a Bloomington, Minn. computer
services company, in a variety of increasingly responsible sales and marketing
positions.

"I stepped aside as CEO in August to facilitate this search and this is the type
of executive I was seeking who can help PSDI accomplish its goals," said Bob
Daniels, PSDI founder and chairman of the executive committee of the board. "The
board is very pleased that David is joining us to help lead PSDI in the next
phase of its growth in revenue and profitability."

Dean Goodermote, chairman of the board of PSDI, added, "We look forward to
taking advantage of David's extensive background in client/server application
software, strong international experience, and proven track record in helping
Hyperion grow from $1 million in 1986 to nearly $200 million in 1996."

The board expects that Sample will begin in his new role in late February. It is
expected

government agencies, and other organizations to assist them in maintaining
high-value capital assets such as plants, facilities and production equipment.
The Company's products are designed to enable customers to reduce downtime,
