Essential criteria

• Systems Design (DESN) level 4 - Designs system components using appropriate modelling techniques following agreed architectures, design standards, patterns and methodologies. 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, simulates or prototypes the behaviour of proposed system components to enable approval by stakeholders. Produces detailed design specifications to form the basis for the construction of systems. Reviews, verifies and improves own designs against specifications.
• Infrastructure Operations (ITOP) level 4 - Applies technical expertise to maintain and optimise technology infrastructure, executing updates and employing automation tools. Configures tools and/or creates scripts to automate infrastructure tasks. Maintains operational procedures and checks that they are followed, including adherence to security policies. Uses infrastructure management tools to monitor load, performance and security metrics.
• Network Support (NTAS) level 4 - Applies technical expertise to maintain and optimise network infrastructure, executing updates and employing automation tools. Uses network management tools to monitor load, performance, and security statistics. Investigates and enables the resolution of network-related operational and security issues. Configures tools and/or creates scripts to automate network tasks. Maintains operational procedures and check that they are followed. Provides reports and proposals for improvements to stakeholders. Contributes to the planning and implementation of network maintenance, updates and security enhancements. Implements agreed network changes and maintenance routines.
• Network Design (NTDS) level 4 - Designs specific network components using agreed architectures, design standards, patterns and methodology. Translates logical designs into physical designs that meet specified operational parameters for capacity and performance. Reviews and verifies network designs again non-functional requirements, including validation and error correction procedures, access, security and audit controls. Contributes to the development of recovery routines and contingency procedures. Contributes to alternative network architectures, networking topologies and design options.
