Systems design DESN


The design of systems to meet specified requirements, agreed systems architectures, and adhering to corporate standards.

Guidance notes

Activities include - but not limited too...

  • using design concepts to develop system design and provide the basis for systems construction and verification
  • designing or selecting  system components
  • developing a complete set of detailed models, properties, and/or characteristics described in a form suitable for implementation
  • adopting and adapting of system design lifecycle models based on the context of the work - using predictive (plan-driven) approaches or adaptive (iterative/agile) approaches for system design

Systems design: Level 6


Develops and drives adoption of and adherence to organisational policies, standards, guidelines, and methods for system design. Champions the importance and value of system design principles and the selection of appropriate systems design lifecycle models. Leads system design activities for strategic, large and complex systems development programmes. Develops effective implementation strategies consistent with specified requirements, architectures and constraints of performance and feasibility. Develops system design requiring the introduction of new technologies or new uses for existing technologies.

Systems design: Level 5


Designs large or complex systems and undertakes impact analysis on major design options and trade-off. Ensures that the system design balances functional and non-functional requirements. Ensures that appropriate system design methods, tools and techniques are applied effectively. Makes recommendations and assesses and manages associated risks. Reviews others' system design to ensure selection of appropriate technology, efficient use of resources, and integration of multiple systems and technology. Adopts and adapts system design methods, tools and techniques. Contributes to development of system design policies, standards and selection of architecture components.

Systems design: Level 4


Designs system components using appropriate modelling techniques following agreed architectures, design standards, patterns and methodology. Identifies and evaluates alternative design options and trade-offs. Creates multiple design views to address the concerns of the different stakeholders and to handle functional and non-functional requirements. Models, simulate or prototypes the behaviour of proposed systems components to enable approval by stakeholders. Produces detailed design specification to form the basis for the construction of systems. Reviews, verify and improve own designs against specifications.
