The decision to automate can be challenging. Clearly computers have many advantages—productivity, speed, quality, scale, consistency, and reduction of human injury. Automated actors are more capable in low-judgment settings where well-known and repeatable activities are performed, like timing the inputs on an assembly line, holding an altitude for an airplane, or checking if every box has been completed on a form. But computers also break down unexpectedly and require maintenance. Humans, on the other hand, are uniquely able to deal with high-judgment activities that feature uncertainty or ambiguity like the diagnosis and treatment of illness, risk assessment, human communication, interaction, and learning.

The decision tree has three main advantages over a decision table. First, it takes advantage of the sequential structure of decision tree branches so that the order of checking conditions and executing actions is immediately noticeable. Second, conditions and actions of decision trees are found on some branches but not on others, which contrasts with decision tables, in which they are all part of the same table. Third, compared with decision tables, decision trees are more readily understood by others in the organization. Consequently, they are more appropriate as a communication tool.

The third phase in the SDLC is design. During design, analysts convert the description of the recommended alternative solution into logical and then physical system specifications. The analysts must design all aspects of the system, from input and output screens to reports, databases, and computer processes. The analysts must then provide the physical specifics of the system they have designed, either as a model or as detailed documentation, to guide those who will build the new system. That part of the design process that is independent of any specific hardware or software platform is referred to as logical design. Theoretically, the system could be implemented on any hardware and systems software. The idea is to make sure that the system functions as intended. Logical design concentrates on the business aspects of the system and tends to be oriented to a high level of specificity. Once the overall high-level design of the system is worked out, the analysts begin turning logical specifications into physical ones. This process is referred to as physical design. As part of physical design, analysts design the various parts of the system to perform the physical operations necessary to facilitate data capture, processing, and information output.
