Data refers to all internal and external digital data available on the web.
As a source of valuable market insights, it is essential for managing a business and developing its offerings.
The big data consultant, also known as a data value consultant, works within organisations to provide consultancy services. These may be organisations that have never taken any action regarding their data, or companies looking to refine their strategy.
The big data consultant begins by collecting and sorting all available data, then moves on to the analysis phase whilst supplementing the companyâs data with external open data.
Through in-depth analysis, they select relevant information regarding market trends, customer behaviour, competitors or the companyâs value chain. This enables them to make recommendations regarding: business direction; the development of a service, product or offering; the acquisition of new tools (internal and/or external) to improve existing systems and capture new market segments and target audiences; and the optimisation of the companyâs operational management.
The data value consultant then organises the implementation of the data project by bringing together all the relevant stakeholders. Once everyoneâs requirements and constraints have been identified and the existing IT system taken into account, they deliver their recommendations: objectives, organisation, planning, technical tools, methods, budget, coordination, etc.

Whether in manufacturing or the service sector, data is an indispensable source of information for developing offerings, products and activities. For example, it enables companies to design new marketing campaigns, validate the launch of a product or service, and plan the companyâs future development.
