Study Notes

Systems Engineering Overview

  • Systems engineering is an integrated approach encompassing software, hardware, people, and processes, aiming to achieve a defined objective.
  • Systems engineering comprises engineered systems, which are composed of interconnected subsystems, assemblies, and elements to produce results not achievable by individual parts.
  • Components include: hardware, software, firmware, processes, people, and information.
  • The value of a system is primarily derived from the relationships among its interconnected components.

Systems Engineering Activities

  • Practice of systems engineering focuses on developing and producing effective, reliable systems, services, or solutions that meet specific needs within defined constraints.
  • Systems development includes a schedule, encompassing commercial and operational domains.

Systems Life Cycle Process

  • The ISO/IEEE 15288 model for system life cycle consists of five stages.
  • These stages include: concept, development, production, utilization, and support, and retirement

Systems Life Cycle Stages:

  • Concept: Planning for the initial stages and defining the needed scope of a system.
  • Development: Design and building of the system to meet the identified needs.
  • Production: Bringing the design to life through manufacturing and assembly.
  • Utilization and Support: Operation of the designed system, maintenance, and providing needed support.
  • Retirement: Dismantling and disposal of the system at the end of its operational life.

System Life Cycle Approach

  • Different life cycle models are used across different stages and aspects.
  • Relevant models include the waterfall, V-model, spiral, and agile models.

Tailoring Process

  • Tailoring processes adapt standard models and methods to address the specific needs of a project or organisation.
  • These tailors procedures adapt and scale processes to manage complexities.
  • Tailoring involves adapting processes to specific risk levels.
  • This process is required when standard processes don't align with the specific needs, complexities, or constraints of a particular project or organisation.

Goals of Engineering Process

  • The goals of an engineering process are to create effective and dependable systems, taking into consideration specific needs and limitations.
  • The process guides the development and delivery of an engineered system.

Systems Thinking

  • Systems thinking emphasizes understanding systems as integrated entities and recognizing the interconnections between various components/elements over time, instead of isolated interactions.
  • It recognizes the influence of intricate dynamics within systems.
  • Systems thinking contrasts traditional, isolated thinking processes, which only consider elements independently.
