Directed Versus Nondirected DSSs

"

"

Silver(1991) proposed a method of classifying DSSs by the degree to which the system

provides decisional guidance-that is, the manner in which a DSS guides its users in

constructing and executing decision-making processes by providing assistance in

choosing and using its operators. Silver defines operators as those elements of the DSS

(menus,buttons,models,algorithme,tools)that cat or must be manipulated by the user

in the course of the decision-making process.This method of classification suggests

that users may benefit from such guidance"imposed"imsed" upon the process by the DSS.

figure1-7 illustrates a two-dimensional matrix of decisional guidance used to classify

various decision support methods.

silver's classification initially categorizes a DSS by the type of uidance provided:

mechanical versus decisional. Mechanical guidance is the more common form within a

DSS and generally consists of assisting user with the "mechanics" of the operating sys-

tem's features such as menus, and commands. In contrast,decisional guidance

assist the users in dealing with the various decision-making concepts relevant to the

problem context. This category can be broken down further into guidance intended to

assist in the structuring or execution of the decision-making processes. Finally, each

decisional guidanc subcategory can be classified by the formthe guidance takes:

suggestive or informational. The former proposes courses of action to the user.Ex-

amples of suggestive guidance would be a suggestion from the DSS regarding which

operator to invoke in the next step or a recommended starting value as to a
