The document discusses the system development life cycle (SDLC), which includes 5 stages: system planning, system analysis, system design, system implementation, and system operation. The accountant plays an important role in several of these stages. In system planning, accountants provide expertise in evaluating feasibility and ensuring careful planning. In system analysis, accountants are important players in designing controls. In system design, accountants ensure accounting considerations are included. In implementation, accountants help with training and follow-up studies. In operation, accountants participate in post-implementation reviews and periodic system reviews.
