Whilst computers and databases can make processes such as providing repair estimates seem straight-forward the underlying process can be complex such that an average equipment owner may find it difficult, if not impossible, to determine a fair repair cost as they generally rely on the dedicated service personnel 's recommendations and knowledge. However, designed appropriately as taught by the inventors an owner may obtain a repair estimate, and/or check the fairness of a repair estimate, with only limited knowledge. Further, the equipment owner may adjust an estimate by selecting / varying elements such manufacturer, replacing original equipment manufacturer parts with secondary market manufacturer parts, or adjusting the specification of the part or parts. However, in doing so the user should be prevented or limited from decisions that are not advisable and allowing them to balance their desired performance versus expenditure. |
