HR consultants help clients with human capital questions within their organisations and / or with improving the performance of the HR department. Chief topics central to the job description of HR consultants are, among others, organisational changes, change management, terms of employment, learning & development, talent management and retirement. HR consultants are also brought in by organisations to help transform the business culture within their organisation, or transform their HR department, which includes changes in the area of organisational design, processes and systems, among others. HR consulting forms, together with strategy consulting, the two smallest segments of the consultancy industry, and the number of consultants active in this domain is, therefore, lower than those in other parts of the industry.

Technology consultants, also known as IT, ICT or digital consultants, focus on helping clients with the development and application of Information Technology (IT) within their organisation. IT consultants focus on transitions (projects) in the ICT-landscape, contrary to regular IT-employees, who work on day-to-day IT operations (so-called ‘business as usual’ activities). The majority of ICT-consultants work on implementation projects, for instance, extensive ERP systems applications, where their role may vary from project management to process management or system integration. Within IT consulting, the fastest growing markets are digital, data analytics (also known as data science), cyber security and IT forensics.
