9. Avicenna System Analysis and Design System Planning9 Overview of Feasibility Points to be considered when assessing technical feasibility Points to be considered when assessing technical feasibility Does the company have necessary hardware, software, and network resources? If not, can these resources be acquired? Does the company have necessary hardware, software, and network resources? If not, can these resources be acquired? Does the company have needed technical experience? Does the company have needed technical experience? Does the proposed platform have sufficient capacity? Does the proposed platform have sufficient capacity? Will the hardware and software environment be reliable? Will it integrate with other company information systems? Will the hardware and software environment be reliable? Will it integrate with other company information systems? Will the combination of hardware and software supply adequate performance? Will the combination of hardware and software supply adequate performance? Will the system be able to handle future transaction volume and company growth? Will the system be able to handle future transaction volume and company growth?

10. Avicenna System Analysis and Design System Planning10 Sequence Summary A key activity in project planning is the assessment of four feasibility issues associated with the project A key activity in project planning is the assessment of four feasibility issues associated with the project Feasibility Study determines the probability of success of proposed system ’ s development project and assesses the project ’ s Feasibility Study determines the probability of success of proposed system ’ s development project and assesses the project ’ s Feasibilities that should be examined include Operational, technical, economic, and schedule. Feasibilities that should be examined include Operational, technical, economic, and schedule. Operational feasibility determines if the human resources are available to operate the system once it has been installed Operational feasibility determines if the human resources are available to operate the system once it has been installed Technical feasibility refers to technical resources needed to develop, purchase, install, or operate the system Technical feasibility refers to technical resources needed to develop, purchase, install, or operate the system
