When an organization undertakes a major Information Technology project, most executives, managers, and project sponsors overlook an important component in the total cost of ownership equation; “maintenance and enhancements“. I am not referring to software, hardware, and cloud hosting maintenance fees. When capitalized dollars are used as the funding source for the project, due diligence is given to these items as these costs are folded into the depreciation schedule associated with the endeavor. I am referring to the steady state costs. Based on the architecture and design patterns employed in the project, what are the future carrying expenses as enhancements and maintenance activities are performed?
