BSC suggests viewing an enterprise from four (4) Overview of Enterprise Architecture Process perspectives: 1. Customer perspective 2. Financial perspective 3. Internal business process perspective 4. Learning and growth perspective. Business Model Development – It is the development of a model that identifies the products or services the business will sell, the target market it has identified, and the expenses it anticipates (Kopp, 2019). o Business Model Canvas – This is a template in creating high- level descriptions of new or existing business models. It consists the following elements: value propositions, key activities, key resources, key partners, customer segments, customer relationships, channels, cost structure, and revenue streams. These are laid out in a user-friendly and intuitive manner. Figure 1.

IT Implementation – It involves the process of combining the developed software or application with the other management and engineering processes (Lankhorst, 2017). o Capability Maturity Model Integration (CMMI) – This is a model that provides numerous guidelines for assessing the maturity of an organization and the improvements needed in various process areas to proceed from one level to the next. These are the five (5) maturity levels of CMMI: 1. Initial – Processes are usually impromptu and chaotic. 2. Managed – Processes are planned, performed, measured, and controlled. 3. Defined – Processes are defined in terms of standards, procedures, tools, and methods. 4.
