These commonalities would make it appear that software engineering is merely an application of systems engineering, but this is only a superficial appearance. The differences between the two disciplines arise from two fundamental concerns:. Table 1 itemizes some of the shared concepts that are applied in different ways by systems engineers and software engineers.
Each discipline has made contributions to the other. Table 1 indicates the methods and techniques developed by systems engineers adapted for use by software engineers and, conversely, those that have been adapted for use by systems engineers.

It also provides more details on the relationship between systems and software life cycles and some of the detailed tools used by software engineers.
As systems become more dependent on software as a primary means of delivering stakeholder value, the historical distinction between software and systems engineering may need to be challenged.

Software engineers carry out software engineering projects, which usually have a standard software life cycle. For example, the Water Fall Software Life cycle will include an analysis phase, design phase, development phase, testing and verification phase and finally the implementation phase. Analysis phase looks at the problem to be solved or the opportunities to be seized by developing the software.
Sometimes, a separate business analyst carries out this phase. However, in small companies, software engineers may do this task. Design phase involves producing the design documents such as UML diagrams and ER diagrams depicting the overall structure of the software to be developed and its components.
Development phase involves programming or coding using a certain programming environment. Testing phase deals with verifying that software is bug free and also satisfies all the customer requirements. Finally, the completed software is implemented at the customer site some times by a separate implementation engineer. In recent years, there has been a rapid growth of other software development methodologies in order to further improve the efficiency of the software engineering process.
For example, Agile methods focus on incremental development with very short development cycles. Software Engineering profession is a highly rated job because of its very high salary range.
