Systems development is the process of creating and maintaining information systems, including hardware, software, data, procedures and people. It combines technical expertise with business knowledge and management skill. This practical book provides a comprehensive introduction to the topic and can also be used as a handy reference guide by those already working in the field. It discusses key topics of systems development such as lifecycles, development approaches, requirements engineering and how to make a business case, among others. It is the only textbook that supports the BCS Certificate in Systems Development.
