The (broader) market for IT consulting services consists of eight main disciplines: IT Strategy, IT Architecture, IT Implementation, ERP services, Systems Integration, Data Analytics, IT Security and Software Management.
IT strategy focuses on strategic IT propositions and IT advisory, offerings which commonly represent the first phase of any IT undertaking. Engagements typically last between six weeks to six months depending on the complexity, with the average lying at two to three months. Examples of projects include defining a corporate IT strategy, setting up a business case for an ERP system or designing a cybersecurity vision – engagements that set the stage for further IT work. IT architecture looks at the IT processes and systems, and defines the technological blueprint that enables business processes. Projects typically last between six to 12 months and architecture services precede any IT implementation or systems integration efforts. Consulting offerings include, among others, defining an enterprise landscape, implementing a service-oriented architecture (SOA), or guiding the outsourcing of architecture processes to an external vendor.
Technology consultants are hired by clients to support them with using information technology to meet business objectives or overcome problems. The type of work can range from strategic (such as developing a new IT strategy or IT cyber-security approach) to tactical (such as the implementation of an ERP system or the selection of an IT system) to highly operational (such as the development of a mobile application).
