The bottom of the matrix is the prioritized and weighted technical requirements. It identifies the requirements that are the most critical for success, which is illustrated through a bar chart to provide quick analysis of the key technical requirements. This is followed by a concept evaluation section in which different system alternatives are compared for determination of how well technical requirements are met. Land Cover Map QFD methodology proved to be a useful tool for customer needs assessment directly involving the user in the process of technological development. Quantitative analysis of data in the matrices allowed to better define the relationships between the customer needs and technical requirements and to evaluate the role high-resolution satellite imagery could play in different mapping applications for local planners and managers.
Customer needs and requirements have a tendency to evolve in time.
Monitoring and analyzing the evolving needs and identifying socio-economic factors impacting their development will be the focus of future research. Working together, city and county officials and planners have become the focal point for needs assessment, community interaction approaches, identification of information requirements, output product definition, preferred delivery mechanisms, and data requirements such as timeliness, accuracy, database size, etc. Several application areas were used to support the implementation.
