The Reality “The best of all possible worlds” Gottfried Leibniz

! Modeling is performed on all levels: System, Function, Hardware and Software ! Best – most suitable – tool is used for the specific purpose ! Models are used for domain specific purposes …

! to describe, in the sense of documenting, the problem and its solutions ! to simulate solutions ! to conduct analyses in order to optimize the solutions

However, there are still some challenges and lacks: ! A significant number of gaps in the seamless and integrated approach across all domains ! A lot of legacy must be carried on ! A large number of individuals/engineers with various and different domain knowledge are

involved in the development, maintenance and operations of a system

One Pain Killer Architecture

! Architecture ! IEEE 1471 Recommended

practice for architectural description of software-intensive systems

! Shared views among stakeholders result in a common model

! Two Stakeholders have a common Concern and one model represents this Concern

The Dream Some people call it “A Vision”

! Seamless and integrated approach supported by a couple, a.k.a. Tool Box, of methods and tools

! Role based work-flow driven tools enabling one to use the most appropriate method and tool

! Support for abstraction and architecture management/engineering

The Nightmare Does it really need to become a nightmare?

! Could you imagine the amount of information we are dealing with? ! Could you imagine how many parameters and/or characteristics are varying when taking

decisions during a system’s lifetime? ! Got this bad feeling while trying to keep the “Cost-Quality-Function Triangle” in balance?

Conclusion … and how to let it not become a nightmare!

! Manage complexity by abstraction, separating viewpoints and focusing on important concerns … be reminded that we cannot reduce complexity!

! Use of sound methodologies and tools that support dealing with multi-concerns and their inter-dependencies

! Establish and increase an understanding of Architecture Engineering

! Further help from funded research projects: ! Automotive, Railway, Avionic Multicore Systems ARAMiS ! Software Platform Embedded Systems SPES 2020 and

SPESxt
