Dynamic workflow architectures for loan processing

A method for processing a loan application, comprising:

• launching a top-level activity for processing the loan application on an activity engine;
• associating a conductor with the top-level activity, wherein the conductor maintains the current state of the top-level activity and manages an event queue;
• decomposing the top-level activity into a plurality of child activities, wherein each of the child activities represents a task to be completed in processing the loan application;
• launching the plurality of child activities on the activity engine;
• associating an activity manager and an activity performer with each of the child activities, wherein each of the activity managers manages the respective child activity and each of the activity performers performs the respective child activity by calling at least one service;
• each activity manager determining the current state of its respective child activity,
• the conductor receiving the current state of a child activity from its respective activity manager,
• the conductor calling the activity engine to perform the plurality of child activities unless the current state of each of the child activities is complete,
• the activity manager causing the activity performer to perform the child activity unless current state of child activity is complete,
• the activity performer of a child activity having one or more lower-level child activities calling the activity engine to perform the one or more lower-level child activities unless the current state of each of the one or more lower level child activities is complete, wherein the plurality of child activities and one or more lower-level child activities are performed using one or more inputs specific to each activity at the time of performance based on a set of constraints specific to each activity,
• the conductor receiving an event signaling a change in state of a dependent child or lower-level child activity that is dependent upon one or more other child or lower-level child activities,
• each activity manager of the one or more child or lower-level child activities from which the dependent child or lower-level child activity depends receiving from the conductor the event signaling a change in state of the dependent child or lower-level child activity, wherein the change of state of the dependent child or lower-level child activity indicates that one or more child or lower-level child activities from which the dependent child or lower-level child activity depends is no longer valid with each activity manager of the one or more child or lower-level child activities that are no longer valid causing the respective activity performer to perform the respective child or lower-level child activity until it is complete, and
• presenting a user having a role with a user interface (UI), wherein the UI includes a list of child activities and lower level child activities comprising a subset of the plurality of child activities and one or more lower level child activities that is a function of the user's role and the state of each of the plurality of child activities and one or more lower level child activities, and wherein the UI includes visual state indicators associated with and corresponding to the current state of each of the listed child and lower level child activities.
