Method and device for managing project by using cost payment time point setting

A project management device using a setting of a cost payment time point, the project management device comprising:

• a communication unit;
• a memory including at least one process necessary for project management using the setting of the cost payment time point;
• and
• a processor operating depending on the process,
• wherein the processor is configured, based on the process, to:
• transmit source data of an n-th child project among a plurality of child projects connected in sequential order to a first task processing terminal and request the first task processing terminal to process the n-th child project, wherein ‘n’ is a natural number;
• receive result data that is a processing result of the n-th child project from the first task processing terminal, in response to the request;
• store the result data at a specific location in a hardware memory, and generating location information including an address value of the specific location;
• record the location information at a result pointer of the n-th child project by changing a value of the result pointer of the n-th child project from a garbage value or null value to an address value corresponding to the location information;
• record the location information at a source pointer of an (n+1)-th child project among a plurality of child projects by changing a value of the source pointer of the (n+1)-th child project from another garbage value or null value to the address value corresponding to the location information;
• automatically obtain the result data stored at the location indicated by the source pointer as source data of the (n+1)-th child project among the plurality of child projects, by using the result pointer of the n-th child project and the source pointer the (n+1)-th child project, which have the same location information;
• when the source data of the (n+1)-th child project is obtained, update data attribute information related to the n-th child project or the (n+1)-th child project;
• transmit the source data of the (n+1)-th child project to a second task processing terminal and request the second task processing terminal to process the (n+1)-th child project;
• and
• determine a cost payment for processing of the n-th child project to the first task processing terminal based on a response of the second task processing terminal to the request,
• wherein each of the plurality of child projects includes one or more tasks, and is divided depending on a type of a task included in each of the plurality of child projects,
• wherein each of the tasks indicates a minimum unit task to be processed by a task processing terminal,
• wherein the processor is further configured to:
• obtain the result data of the n-th child project as the source data of the (n+1)-th child project by using at least one of a data pointer and data filtering;
• when obtaining the source data of the (n+1)-th child project by using the data pointer, update pointer-related data attribute information;
• and
• when obtaining the source data of the (n+1)-th child project by using the data filtering, update filtering-related data attribute information,
• wherein the pointer-related data attribute information includes a result pointer value of the n-th child project and a source pointer value of the (n+1)-th child project,
• wherein the filtering-related data attribute information includes a filtering status of the n-th child project and a filter pass list, and
• wherein the processor is further configured to:
• select a processing-impossibility selection for the (n+1)-th child project from the second task processing terminal;
• and
• request the first task processing terminal to re-process the n-th child project instead of a cost payment for the processing of the n-th child project.
