Process Modeling in Software Engineering

Was formalized in the late 1970s. Software engineers and computer scientist need a way to represent and analyze complex systems. Purposes of Process Modeling o Specify the essential requirements irrelevant to the technology. o Identify the information for each business workflow. o Provide the necessary requirements to determine development costs. o Minimize development costs through clear user requirements. Process Modeling o Requires the involvement of relevant stakeholders. Client provide the knowledge, data, and associations. Analysts captures the information through RDM. Represent and understand the important aspects of the needs and objectives of the client. What is Decomposition. The process of breaking a complex problem into parts that are easier to conceive, understand, program, and maintain. It allows its sub-problems to be solved faster before being put together to fully solve the original problem. Example #1 Write a program that will ask the user two numbers then display its sum, difference, product, and quotient
