Chapter Objectives n n n Explain the importance of feasibility study Discuss the operational feasibility Discuss the technical feasibility Avicenna System Analysis and Design System Planning 2

Overview of Feasibility n n n A systems request must pass several tests, called a feasibility study, to see whether it is worthwhile to proceed further. Feasibility Study determines the probability of success of proposed system’s development project and assesses the project’s Feasibility analysis is used to aid in the decision of whether or not to proceed with the IS project. Avicenna System Analysis and Design System Planning [1] 3

Overview of Feasibility n n n n Helps us decide where to focus our efforts A study to ascertain the feasibility of a new system A study to justify the NEED for a new system and clarify potential SOLUTIONS Gives management a basis for decisions Feasibility study identifies direction Analysis and models help to understand system and needs Focus on WHAT not HOW Avicenna System Analysis and Design System Planning 4

Overview of Feasibility n Four Categories Operational n Technical n Economic n Schedule n Avicenna System Analysis and Design System Planning 5

Overview of Feasibility n n n Operational Feasibility Operational feasibility determines if the human resources are available to operate the system once it has been installed Users that do not want a new system may prevent it from becoming operationally feasible Avicenna System Analysis and Design System Planning 6

Overview of Feasibility n Operational feasibility vital issues n n n n n Avicenna Management support Users support Workforce reduction: if new system affect workforce, what will happen to affected employees Users training Users involving in new system Performance decline in some system parts Is there any risk to the company’s image The development schedule is it suitable or there is a conflict with other company priorities Legal and ethical issues to be considered System Analysis and Design System Planning 7

Overview of Feasibility n Technical Feasibility n n n Users’ and analysts’ familiarity with the business application area Familiarity with technology n n Have we used it before? How new is it? Project size n n Technical feasibility refers to technical resources needed to develop, purchase, install, or operate the system Number of people, time, and features Compatibility with existing systems Avicenna System Analysis and Design System Planning 8

Overview of Feasibility n Points to be considered when assessing technical feasibility n n n Avicenna 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 proposed platform have sufficient capacity? 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 system be able to handle future transaction volume and company growth? System Analysis and Design System Planning 9

Sequence Summary n n n 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 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 Technical feasibility refers to technical resources needed to develop, purchase, install, or operate the system Avicenna System Analysis and Design System Planning 10

Sequence Summary n In this Sequence we have Defined the feasibility study n Explained the importance of feasibility study n Defined and described the operational feasibility n Defined and described the technical feasibility n Avicenna System Analysis and Design System Planning 11
