Systems Engineering Demystified

By: Jon Holt

Overview of this book

Systems engineering helps us to understand, specify, and develop complex systems, and is applied across a wide set of disciplines. As systems and their associated problems become increasingly complex in this evermore connected world, the need for more rigorous, demonstrable, and repeatable techniques also increases. Written by Professor Jon Holt – an internationally recognized systems engineering expert – this book provides a blend of technical and business aspects you need to understand in order to develop successful systems. You'll start with systems engineering basics and understand the complexity, communication, and different stakeholders' views of the system. The book then covers essential aspects of model-based systems engineering, systems, life cycles, and processes, along with techniques to develop systems. Moving on, you'll explore system models and visualization techniques, focusing on the SysML, and discover how solutions can be defined by developing effective system design, verification, and validation techniques. The book concludes by taking you through key management processes and systems engineering best practices and guidelines. By the end of this systems engineering book, you'll be able to confidently apply modern model-based systems engineering techniques to your own systems and projects.

Introducing OOSEM

OOSEM was originally developed by systems engineers from Lockheed Martin and the Systems and Software Consortium. OOSEM is a systems-level development method that combines object-oriented concepts with traditional systems engineering practices.

OOSEM was originally based on the Object Management Group (OMG) Unified Modeling Language (UML), but since SysML was developed, it has been revisited to use SysML to capture the system model. Because of this, there are explicit mappings between the artifacts in OOSEM and specific SysML diagrams that may be used to visualize them.

Defining OOSEM concepts

The basic structure of OOSEM is shown in the following diagram:

The diagram here shows the ontology definition view for the structure of OOSEM, visualized using a SysML block definition diagram.

The OOSEM comprises one or more activities, each of which is made up of one or more modeling...
