The information (of the meters above) is taken from an overall survey among clients, fieldworkers and staff of GTE. The survey was part of a scientific research within the scope of a SWOT-Analysis, which was created by our strategic management department in 2018. Building the SWOT-Analysis on a representative, anonymous and reliable survey ensured the quality of the instrument due to objective results regarding the strengths, weaknesses, opportunities and threats of the company. The SWOT helped us to evaluate our own market position. As a result, we are capable to both seek further development and empower our advantages compared to our competitors in order to be the best supplier of specified personnel.
