A computer based procedure rendered in flowchart and success logic tree

A computer based procedure called ImPRO has been developed. The procedures are rendered in a flowchart and a success tree. The flowchart shows the skeleton of a procedure, whereas the success tree shows details of the procedure. Two presentations can enhance understandings of procedures. ImPRO decomposes a procedure hierarchically: Procedure, Step, ACheck, and Instruction. The higher level element Procedure and ACheck are shown in the flowchart, and the lower level Instructions are presented in the success logic tree. The flowchart of ImPRO consists of well-defined five symbols and arrows. The flowchart can be collapsed, expanded, and scrolled. The success logic tree works on the three statuses: true/false/unknown. And all the instructions of the success logic tree are combined by N out of M logic operator. The logic can be calculated by computer, but human operators can override the result. Even though ImPRO has high level of automation, the automation logic is transparent to humans
