Ownership: The farmer is the owner as the everyday decision maker and responsible for decisions activating or deactivating targeted functionalities in the system.
Environmental constraints: The constraints influencing the usability and performance of the management information system includes regulations for farm machinery use, safety regulations, external cost impacts, and environmental provisions.
Before implementation it is necessary to evaluate the proposed system in order to ensure the functionality and maintenance under uncertain, complex and dynamic circumstances (Checkland and Scholes, 1990). A logical analysis of the model in Fig. 2 must be performed targeting the feasibility of the proposed activity actions using the indices like efficacy, efficiency, and effectiveness. The definitions of these indices for the proposed system stand as:
Efficacy: Data are easily transferred and used in the tractor/implement system.
Efficiency: Obtaining all data (input) and transforming it are carried at minimal costs.
Effectiveness: Machinery performance and the management of decision making are improved.
