abstract = "This paper aims to present the lessons learned in 20 years of
application of the SCE (Systems Concurrent Engineering) approach
that evolved over the last 20 years being applied to the
development of more than 200 complex system solutions. SCE is an
approach to the integrated development of complex systems that
applies the systems engineering process, simultaneously, to the
product elements of a system solution as well as for the service
elements of the system solution, recursively, at every layer of
the system solution breakdown structure. The approach was born as
the application of the requirements, functional and physical
analysis processes to the simultaneous development of a product,
its life cycle processes and their performing organizations, at
every layer of the product breakdown structure. The continuous
application of the approach up to 2010, showed the need to include
a stakeholder analysis step, to acknowledge that the solution was
comprised of product and organization elements (processes were, in
fact, the functions of products and organizations), that a mission
layer should be added at the top of the product breakdown
structure and that the notion of circumstances should be added to
the traditional notion of scenarios. With the increasing use of
the approach for system of systems conception and development such
as those involving multi-spacecraft solutions, the mission layer
needed to be extended to include other life cycle processes
(besides the operations processes) concept of service and system
service architecture. This requires the development of a system
solution breakdown structure that will guide the development of
the overall solution. For multi-spacecraft solutions, for example,
it is necessary to conceive and architect testing, launching and
decommissioning services as early as operations. Also, going into
more detail in the approach, modes can be derived from
circumstances, interface states and internal states of the system
and not only from circumstances, as initially established in the
approach. These lessons to be presented were learned during the
development of: 1) the Brazilian Strategic Program for Space
Systems (PESE) and; 2) the TIM Project (Telematics International
Mission), a satellite formation with contributions from many
regions in the world.",
