Then there is the adoption of policies which involve one person being chosen to be formally trained. This person is then given responsibility for training everyone else. Sometimes, this can work if the person chosen has the necessary skill sets to be able to train an audience which may consist of users with no knowledge of GIS. In some cases they may even lack a basic knowledge of databases and spreadsheets which is necessary for success in using desktop GIS systems. However, nothing compares with professional training delivered to all those using the software.
Some departments may have had access to a proprietary GIS for many years and yet have failed to get many users beyond using the software at a level which could have been achieved with Google maps.
The answer to making most of the valuable resource that desktop GIS represents is to ensure that a budget is set aside to ensure that over time every potential department and their staff are given at least a day's introductory training on the main features and benefits of the chosen desktop GIS system installed in the organisation.
