The need for consulting services can arise because of unexpected delays in project implementations, changing business conditions, inadequate staffing for new systems development, staff turnover, or the introduction of new technology. Any of these situations can create a short-term need for additional technical staff. The fastest and most efficient way to satisfy these needs is often to bring on consultants. A typical assignment would consist of one or more consultants with specific technical and/or business skills for a specified period of time.
