The DSM is a square matrix in which is assigned the tasks identically ordered at row and columns. The initial process is to mark the cells to identify when a row receives information from a column. Figure 4 shows that the original DSM (left matrix) presents a series of tasks ordered according execution sequence both at rows and columns. Note that the row A has the number 1 marked at columns C and E. It means that the execution of task A needs information from tasks C and E. On the other hand, looking at column A, one can note the number 1 marked at rows B and C. It means that the task A gives information to tasks B and C. Above diagonal marks has a relevant significance: it indicates that an earlier task is dependent on a later task. The original DSM (left matrix) shows that task A depends on information of tasks C and E that were not executed yet.
