1. A network image processing system in which a plurality of networked apparatuses execute independent actions on a target document to complete the target document in stages, wherein the target document is transmitted and received between the apparatuses, each of the apparatuses comprising: a receiving unit for receiving the target document and a first script from an upstream apparatus, the target document including all portions of the target document generated by upstream apparatuses, the first script including a listing of actions which indicate document processing content, sequence information which indicates an execution sequence of the actions including a split at a predetermined point in the execution sequence, and apparatus information which specifies the apparatuses to which the actions are assigned; an execution unit executing an assigned action to generate a portion of the target document; a correlation unit adding, to the first script, location information that indicates a network location of the execution unit that corresponds to the executed assigned action; a transfer unit appending the portion of the target document generated by the execution unit to the target document received from the upstream apparatus, and transferring the first script and the document with the portion of the target document generated by the execution unit and all portions generated by upstream apparatuses to a downstream apparatus, wherein the appended portion and all portions generated by upstream apparatuses collectively constitute a separate stage of completion of the target document, wherein there is a separate stage of completion of corresponding scope for each apparatus, such that there is a separate stage of completion for every appended portion of the target document comprising that specific appended portion and all portions before that specific appended portion; a display unit separately displaying each stage of completion of the target document; a reception unit receiving, from a user, a selection of one of the separate stages of completion; a remand unit remanding, in accordance with the location information corresponding to the portion of the target document for which the selection has been received, the document to the networked apparatus which appended the portion of the document for which the selection has been received; the remand unit transmitting or receiving a second script that defines document handling, wherein the second script is destined to the networked apparatus to which the document has been remanded in accordance with location information corresponding to the portion of the document for which a selection has been received by the reception unit, wherein the second script includes remand information indicating a remand of the script and information specifying the apparatus that selection has been received as a remand-source; a cancel instruction unit; and a position judgment unit judging, based on the apparatus information and the sequence information included in the first script, whether the apparatus is positioned at the predetermined point in the execution sequence indicated in the first script, and if the judgment is affirmative, the cancel instruction unit transmits a cancel instruction to an apparatus on a different branch from the remand-source apparatus that is to execute a subsequent action according to the sequence information indicated in the first script.

The network image processing system of claim 1 , wherein the actions include a manual action requiring a user operation, the first script includes address information specifying an address of a user in charge of the manual action, and each of the apparatuses further includes a notification unit, if the first script includes the remand information and the assigned action is the manual action, sending, to the address specified in the address information included in the first script, a notification of the remand.
