This system planning concerning estimation from physical requirement,labour and cost what is required to support the this growth system and also to support its operation after applied. System planning is also conducted by system department, if this department there is in a company.
b. Systems analyisis
to get the good system hence the system of mistake minimization will or insuffiency, from that needed to analyse the the system. Analyse the system also can be defined as decomposition from something and evaluate problems, opportunity resistance that happened and requirement expected so that can be proposed by its repairs.
c. Desain sistem
systems design according to George M. Scott system design determines how a system will accomplish what it must accomplish; it involves configuring the software and hardware components of a system so that after the installation to the system will fully satisfy the system specifications established at the end of the system analysis phase.
