Information systems (IS) building, as described in the literature, consist of two main phases: IS strategic planning and IS development. The IS strategic planning phase is performed every few years and produces a long-term strategic plan. The IS development phase is performed annually by IS management and produces a development plan for the next year and outlines development activities. The activities performed in the building process are also called in literature system development life cycle (SDLC). Existing models describe sequential activities with a limited amount of dynamism. We argue that dynamism and iterative development are necessary for business competition. Traditional development models were defined by researchers chronologically before work system theory was formalized, thus appropriate revisions are necessary. We propose a new development model that overcomes the limitations of current SDLC models, and enables better mitigation of IS activities with business management's needs as a focal point.
