    The Internet of Things (IoT) refers to the network of interconnected devices that communicate and exchange data over the Internet. IoT applications range from smart homes and wearable technology to industrial automation and healthcare monitoring systems. Blockchain, on the other hand, is a decentralised digital ledger technology that ensures secure and transparent transactions. Originally developed for cryptocurrencies such as Bitcoin, blockchain is now used in supply chain management, digital identity verification and secure financial transactions.

    Together, IoT and blockchain are driving innovations in security, efficiency and transparency across multiple sectors. While CUT’s programme does not have any modules specifically dedicated to these fields, the combination of modules on computer architecture, networking and advanced software programming will provide students with the skills to set up both IoT and blockchain systems.

     

    IT project management

    After completing a postgraduate diploma in information technology, graduates will have learnt effective project management strategies for managing IT projects.

    Agile and scrum methodologies

    Agile management is a set of principles related to project management and is often described as a philosophy. The Agile project philosophy or framework takes an iterative approach towards completing a project, meaning that tasks and goals are broken down into smaller increments with shorter time frames. The term was first coined with the publication of the Agile Manifesto in 2001, which set out 12 principles. At its core, Agile is about being flexible and responsive to changing requirements and feedback. It also emphasizes the importance of fostering continuous collaboration and adaptive planning.

    Although Scrum and Agile are sometimes confused, Scrum refers to a specific methodology within the broader Agile framework that has been widely adopted. Scrum provides a structured way of implementing Agile principles through defined roles and events. Scrum teams include roles such as the product owner, scrum master and development team. Work is broken down into sprints, which typically last two to four weeks. During this period, specific features or components are developed, tested, and reviewed. Scrum emphasises transparency, inspection, and adaptation. Regular events such as Daily Stand-ups, Sprint Planning, Sprint Reviews, and Retrospectives ensure continuous communication and improvement. This approach speeds up delivery and improves product quality by incorporating feedback at every stage.

     

    Risk assessment and mitigation

    CUT’s postgraduate diploma includes a module on Advanced Information Security, which teaches students how to assess and mitigate security risks in IT systems. A second module on ethical hacking takes this further by teaching students how to identify weaknesses in IT systems. By learning how hackers exploit vulnerabilities, students will also gain a better understanding of how to mitigate such risks and ensure that their systems are safe and secure.

     

    Budgeting and resource allocation

    While IT project management requires a depth of IT-specific experience and understanding, managers must still ensure that their projects are carried out within budget. A good IT project manager will allocate available resources as efficiently as possible and make sure that projects are completed on budget and on time.
