The Vaisala Group consists of four business areas: Vaisala Measurement Systems, Vaisala Solutions, Vaisala Instruments and Vaisala Services.
Vaisala Solutions and Vaisala Measurement Systems develop, produce and market systems and solutions for weather observations, and offer services in support of their customers' day-to-day operations. Vaisala Instruments specializes in industrial and environmental measurements. All services are centralized in the Vaisala Services business area which became operational in the beginning of 2008. Operations were also reorganized into one group-wide unit at the beginning of 2008. Vaisala sales is organized into seven sales groups based on the customer segments.
In 2008 Vaisala refocused its strategy in order to serve the customers even more efficiently than before. Following the strategic changes, the organization was restructured into three business areas: Meteorology, Weather Critical Operations and Controlled Environment. Each business area develops their strategies in line with Vaisala’s vision, mission and values to expand and strengthen Vaisala's position in the business. To seek further synergies and to utilize common technology platforms, Vaisala's product creation and product management activities were combined into one group wide Products and Technology unit. All changes became effective in the beginning of 2009.
