CASE 2.1 Harvard Cooperative Society

Objective: To encourage students to appreciate the importance and usefulness of a decision

support system.

Summary: From his office window, Harvard Cooperative Society CEO, Jerry Murphy, can see

customers shopping. They make their way through the narrow aisles of the crowded department

store, picking up a sweatshirt here, trying on a baseball cap there, and checking out the endless

array of merchandise that bears the Harvard University insignia. Watching Murphy, you can well

imagine the Co-op’s founders, who started the store in 1882, peering through the tiny

windowpanes to keep an eye on the shop floor. Was the Harvard Square store attracting steady

traffic? Were the college students buying enough books and supplies for the Co-op to make a

profit? Back then, it was tough to answer those questions precisely. The owners had to watch and

wait, relying only on their gut feelings to know how things were going from minute to minute.

Now, more than a hundred years later, Murphy can tell you, down to the last stock-keeping unit,

how he’s doing at any given moment. His window on the business is the PC that sits on his desk. All

day long it delivers up-to-the-minute, easy-to-read electronic reports on what’s selling and what’s

not, which items are running low in inventory and which have fallen short of forecast. In a matter of

seconds, the computer can report gross margins for any product or supplier, and Murphy can decide

whether the margins are fat enough to justify keeping the supplier or product on board. “We were in

the 1800’s, and we had to move ahead,” he says of the $55 million business.
