Table 10. Application in the harvesting industry of five identified information quality dimensions, based on interviews with experts.
IQ dimension Definition Source Related to harvesting industry
Accurate Free from obvious mistakes Forslund and Jonsson (2007) The information should be accordance with reality. Even if the work order is downloaded from the web portal, it needs to reflect the current situation.
Complete The extent to which the information is comprehensive Gustavsson and Jonsson (2008) The work order and instructions should be understandable for the person conducting the harvesting. The work order contains predefined fields and these are to be comprehensible for the logging contractor. The information quality regarding the completeness of the separate work orders is considered to be rather high; therefore, completeness with regard to information quality will not be assessed further in this study.
Relevant The extent to which the information is appropriate for the task and application Gustavsson and Jonsson (2008) The work order and attached information should be designed so all needed information is included. It is not possible for the sender to load the work order on the web portal if all fields are not filled in. The information quality regarding the relevance of the separate work orders is considered to be rather high; therefore, relevance with regard to information will not be assessed further in this study.
Reliable The probability that the forecast remains unchanged Gustavsson and Jonsson (2008) When logging contractors and timber buyers close annual agreements, they do not have discussions regarding the specific work orders. The information quality regarding the reliability of the separate work orders is considered to be rather high; therefore, reliability with regard to information will not be assessed further in this study.
Timely Arrives in agreed time Gustavsson and Jonsson (2008) The logging contractor and the timber buyer close an agreement on when the work order should be sent to the contractor, normally 2 weeks in advance. Information regarding each work order information component is received together. If the logging contractor has not received the work order, it is impossible to conduct the logging work. The relevance of timeliness is with regard to the work order and not the individual work order components.
Table 11. Tentative factor characteristics.
Original factor name Nature Type of work preparatory*/ necessity** Value when conducting work for the logging contractor
Factor 1 Administrative Preparatory Prerequisite
Factor 2 Administrative Preparatory N.A.
Factor 3 Administrative Preparatory Prerequisite
Factor 4 Administrative Preparatory Facilitation Prerequisite
Factor 5 Practical Necessity N.A.
* = preparations the timber buyer is expected to have done before harvesting.
** = necessity in order for the logging contractor to access the area to be harvested.
