Business Oriented Systems Development means that the development of systems always focus on the purpose of the business and how the business best should be operated, not on the product alone. Modelling and simulation makes the Business Oriented Systems Development possible in a concrete way. Both needs and current circumstances can be visualised by developing models and simulations of the business, scenarios and processes. The visualisation and elucidation provided by modelling and simulation result in a maintained focus
during the systems entire life cycle. The communication and discussions improves between those with needs and requirements, and those who suggest and develop solutions.
Life Cycle Oriented Systems Development aims towards early foreseen of future requirements regarding the system in relation to development, production, utilization, support and retirement. Early and gradual implementation
and integration of product models and simulations, defined iteratively during development, is supported by the principals of a life cycle oriented system development. In other words prototypes, with various levels of detail,
are developed through modelling. The models of the products are then evaluated and tested regarding future life cycle stages through execution of the models (simulation).
The Federation Development and Execution Process (FEDEP) define one approach to development of models and execution of those models in simulations and in
particular High Level Architecture (HLA) Federations. FEDEP can be recommended as a method for all development of models and executions of simulations.

The international standard for systems engineering CT:ISO/IEC 15288 “Systems Engineering Life Cycle Processes” receives more and more attention; probably due to an increasing need for a common framework within the systems engineering community. For example; NATO has decided that ISO/IEC 15288 shall be the framework for Systems Life Cycle Management (SLCM).
Architectural Frameworks is sometimes regarded as the necessary
communication tool of system design when stakeholders communicate what the systems are, the purpose they fulfil, and
what the systems elements are. Department of Defence (DoD), NATO, Ministry of Defence (MOD) and the Swedish
Armed Forces to mention a few, all develop Architectural Frameworks. Modelling & Simulation (M&S) is the “silver
bullet” that will make systems engineering more efficient with respect to delivering the right systems; within budget and
time limits. The present paper will give a brief introduction to ISO/IEC 15288, Architectural Frameworks and M&S. It
will also present an example on how ISO/IEC 15288, Architectural Frameworks and M&S can be integrated and the benefits of that integration, especially how M&S can be used to develop and execute system designs.
Finally this paper gives a very short presentation of some ideas concerning tool support. The presented work was performed under
contract from the Swedish Defence Material Administration.
The international standard ISO/IEC 15288 ”Systems
Engineering Life Cycle Processes”  describes
processes appropriate for systems engineering and offers
stakeholders a common process framework that improves
the communication and cooperation during a systems
entire life cycle.
The processes in ISO/IEC 15288 can be used by
organisations, projects, acquisition managers and/or
system suppliers to create life cycle models appropriate to
the products and services. For example; an organisation
can use the processes to develop a common framework
supported by methods, procedures, tools and trained
personnel. Based on the framework, a project can decide
which processes to use to secure the delivery of the
intended products and services.
Acquisition managers and system suppliers can use the framework to reach an agreement concerning the processes used by the
respective party and the necessary demands on the processes. NATO has decided to use ISO/IEC 15288 as the framework for Systems Life Cycle Management (SLCM)  and the Swedish Defence Material Administration (FMV) to use ISO/IEC 15288 as the
framework for systems engineering.
