Research paper : Construction of a traceability matrix for high quality project management (A. Sakaedani et al.)−9−Synthesiology - English edition Vol.5 No.1 (2012) or 1.5) are assigned to each team and activity element, and the component value of the matrix is set by multiplying the difficulty of the row and column.As a result, it is found that a difficulty level of 104.89 is obtained for the whole project (Table 3). This is greater than the value of 78.18 in scratch development, and is also greater than the difficulty level of 64.75 when the generator is used as an alternative plan.Based on the above data, the complexities of the project when PKG, generator, and scratch are used are reevaluated. The results are shown in Table 3, and the conclusion is that the use of the generator is optimal. 5.2 DOThe project is executed as planned, and the development is carried out. For example, in the aforementioned case, the development is conducted using the generator. 5.3 CHECKUp to the previous subchapter, the comparison of multiple projects is discussed, but in this subchapter, the discussion will be focused on one project and on its changes over time.The complexity decreases as development progresses. This is because the interdependency disappears between elements where information transfer has been completed, and ultimately the value of matrix elements that initially showed interdependency will reach 0. At the same time, the difficulty decreases with the change in progress over time, owing to the effect of proficiency. However, the complexity does not necessary become an elemental value of 0. For example, it is normally difficult to understand all the specifications of the package software and to become proficient in skills that allow dealing with any kind of situation within the limited development period. However, the interdependency becomes 0 when the information transfer is completed. Therefore, by setting the system matrix that expresses difficulty as Sn and the order of the system matrix as N, in the matrix component Fig. 7 Network model of PKG development (for screen transition only)Fig. 8 Network model of generator development (for screen transition only)FunctionComponentArtifactActivity<>Screen design<>Screen specification<>Screen control PKG function<>Screen controlPKG<>Screen transition diagramFunctionComponentArtifactActivity<>Screen design<>Screen specification<>Deposit screen<>Deposit amount input function<>Withdrawal amount input function<>Menu selection function<>PW input function<>UIDinput function<>Withdrawal screen<>Menu screen<>Login screen<>Screen transition diagram
