View source for Systems Engineer MBSE what rationale

''Elaboration''

You have:

* exploited the various tutorials and documentated case studies available online (see elsewhere in INCOSE UK, and INCOSE.org for links - refine to include links here)
* gained access to at least one of the tools that support MBSE - there are both COTS and open source tools available - and experimented in a sandbox;
* connected to the local community of other MBSE systems engineers, via your organisation and/or INCOSE;
* considered commercially available training for MBSE (note this can be 'badged' as 'SysML for MBSE' or some such;
* built up experience incrementally. 

''Rationale''

Aliging what you do as an individual with your organisation's approach is important, since the majority of benefits from MBSE only come from the sharing of common information around a systems model - and possibly other models related to that model. Such sharing could be across 2 or more systems engineers, across systems engineers and other engineering disciplines, or across engineering and non-engineering disciplines (project management, commercial, product support, procurement...).

Becoming proficient in performing systems engineering in a model-based way requires a combination of awareness and education, and practical hands-on use. It also helps greatly to work with others who have either come up the learning curve, or at least are also going up it. Bear in mind that MSBE is still systems engineering!
