A Note on The Influence of Software

Not that this process does not require great skill, but it is a skill analogous to that of the journalist of choosing the right words and constructing sentences and paragraphs that produces the correct understanding in the reader s mind of the 

It is also worth while noting at the relative effort expended on engineering and on software development can vary greatly from project to project. On a 2 billion dollar freeway project the software development component may account for 5 million dollars and the engineering 100 million, whereas on a project to develop a new ERP module, there may be no engineering at all. In the latter case, the requirements are developed by business analysts, and the hardware platform is existing. This variability is a further indication of the relative independence of the two activities, and dispels the notion that they are two sides of the same coin and therefore need to have a common approach. 

In summary, then, the significant differences between engineering and software development in the nature of both their products and their activities give rise to doubts about the current trend in systems engineering of adopting methodologies, representations, and tools from software development without a critical examination of their applicability. You should keep this in mind when assessing the applicability of the standards and current practice to your projects. 

Numerous other organisations in the defence and aerospace industry, such as NASA and the European Cooperation for Space Standardization, have published their own systems engineering standards, and the Australian DoD issued its Capability Systems Life Cycle Management Manual in 2002. 

However, when applying ISO 15288 to any organisation, be it a permanent organisation, such as a company or a government body, or a temporary project
