Difference between design and analysis in civil engineering

Engineering analysis is the process by which an engineer develops a model of an engineering problem and uses the model to obtain useful engineering information. Engineering design is the iterative process through which an engineer creates new devices, structures, and processes.Roughly speaking, "analysis" designates some kind of understanding of a problem or situation, whereas "design" is related to the creation of a solution for the analyzed problem; a "model" is some kind of simplification that is used to better understand the problem ("analysis model") or the solution ("design model") [Rumbaugh et al. 91].The difference between analysis and design can be understood by recognizing that design verification is primarily concerned with ensuring that the software will meet requirements. Analysis on the other hand is primarily concerned with identifying the requirements and testing how the desired result fits into the software's implementation.Design: Model: some kind of understanding of a problem or situation. creation of a solution for the analyzed problem. simplification that is used to better understand the problem (“analysis model”) or the solution (“design model”).
