1. 系统工程师:
系统工程师是在工程项目的生命周期内处理工程项目整体管理的人(更多地关注物理方面)。他们遵循跨学科的方法,管理将需求转化为解决方案所需的全部技术和管理工作。他们通常专注于基于计算机的系统开发的所有方面,不仅如此,还包括硬件、软件和过程工程等。

系统工程方法:

  • 利益相关者分析
  • 接口规格
  • 设计权衡
  • 配置管理
  • 系统验证和确认
  • 需求工程

2. 软件工程师:
软件工程师是负责设计和开发高质量软件应用程序/软件产品的人。他们遵循系统和规范的方法来进行软件应用程序的软件设计、开发、部署和维护。他们通常关注系统中软件开发、基础设施、控制、应用程序和数据库的所有方面。

软件工程方法:

  • 流程建模
  • 增量验证和验证
  • 流程改进
  • 模型驱动开发
  • 敏捷方法
  • 持续集成

系统工程师和软件工程师的区别:

S.No. SYSTEM ENGINEER SOFTWARE ENGINEER
01. A System Engineer is a person who deals with the overall management of engineering projects during their life cycle (focusing more on physical aspects). A Software Engineer is a person who deals with the designing and developing good quality of software applications/software products.
02. System Engineers follows an interdisciplinary approach governing the total technical and managerial effort required to transform requirements into solutions. Software Engineers follows a systematic and disciplined approach for software design, development, deployment and maintenance of software applications.
03. In general they are concerned with all aspects of computer based system development including hardware, software and process engineering. In general they are concerned with all aspects of software development, infrastructure, control, applications and databases in the system.
04. One thing software engineering can learn from system engineering i.e Consideration of trade-offs and use of framework methods. One thing system engineering can learn from software engineering i.e Disciplined approach to cost estimation.
05. System engineers mostly focus on users and domains. Software engineers mostly focus on developing good software.
06. Systems Engineering Methods are Stakeholder Analysis, Interface Specification, Design Tradeoffs, Configuration Management, Systematic Verification and Validation, Requirements Engineering etc. Software Engineering Methods are Modeling, Incremental Verification and Validation, Process Improvement, Model-Driven Development, Agile Methods, Continuous Integration etc.
07. It ensures correct external interfaces, interfaces among subsystems and software. It makes interfaces among software module, data and communication path work.
08. System Engineers requires a broader education background like Engineering, Mathematics and Computer science etc. While Software Engineers requires Computer Science or Computer Engineering background.

但这两个学科是相互关联的,IT 行业对这些职位没有如此严格的规则,我们也可以看到这两个学科是如何相互合作的。
