Consultancy companies offer professional research and advisory within a certain field of expertise to other companies and public organizations. They operate on a project basis: as an umbrella agency, they summon a team of consultants or delegate a consultant for every contracted project.
Consultancy is a broad term; consultants work in multiple areas: providing professional assessment and planning to the government, massive data science- and biotechnological projects, business management, general management, education, conflict resolution, market research, planning the public infrastructure, professional training, etc.
You might be asking yourself, “How does such a consultancy company differ from a corporation?” Well, consultancy companies have a different mission, philosophy, and modus operandi than corporations—which also implies that careers within those companies differ from typical corporate careers. A corporation usually develops their own flagship product, service, or a range of services that represent their vision (or, their “why,” Sinek, 2011) and sell to individual customers or other businesses.
On the contrary, a consultancy company assists other companies in developing their vision and providing between services and products to their customers—as well as helping public institutions in building a better infrastructure for their citizen. While corporations compete to become the market leader among producers of RTV equipment, providers of digital services, or manufacturers of cars or planes, consultancy companies compete to become the best business advisor, the best predictor of the future market trends, and the best barometer of public opinion, and the best planner for the client’s projects.
