Question 6: What is feasibility? List and briefly discuss four feasibility tests.
A systems request must pass several tests, called a feasibility study, to see whether it is worthwhile to proceed further. A feasibility study uses four main yardsticks to measure a proposal:
Operational Feasibility: Operational feasibility means that a proposed system will be used effectively after it has been developed. If users have difficulty with a new system, it will not produce the expected benefits. Operational feasibility depends on several vital issues. For example, consider the following questions:
Does management support the project? Do users support the project? Is the current system well liked and effectively used? Do users see the need for change?
Will the new system result in a workforce reduction? If so, what will happen to affected employees?
Will the new system require training for users? If so, is the company prepared to provide the necessary resources for training current employees?
Will users be involved in planning the new system right from the start?
Will the new system place any new demands on users or require any operating changes? For example, will any information be less accessible or produced less frequently? Will performance decline in any way? If so, will an overall gain to the organization outweigh individual losses?
Will customers experience adverse effects in any way, either temporarily or permanently?
Will any risk to the company's image or goodwill result?
Does the development schedule conflict with other company priorities?
Do legal or ethical issues need to be considered?
Technical feasibility: Technical feasibility refers to the technical resources needed to develop, purchase, install, or operate the system. When assessing technical feasibility, an analyst must consider the following points:
Does the company have the necessary hardware, software, and network resources? If not, can those resources be acquired without difficulty?
Does the company have the needed technical expertise? If not, can it be acquired?
Does the proposed platform have sufficient capacity for future needs? If not, can it be expanded?
Will a prototype be required?
Will the hardware and software environment be reliable? Will it integrate with other company information systems, both now and in the future? Will it interface properly with external systems operated by customers and suppliers?
Will the combination of hardware and software supply adequate performance? Do clear expectations and performance specifications exist?
Will the system be able to handle future transaction volume and company growth?
Economic Feasibility: Economic feasibility means that the projected benefits of the proposed system outweigh the estimated costs usually considered the total cost of ownership (TCO) , which includes ongoing support and maintenance costs, as well as acquisition costs. To determine TCO, the analyst must estimate costs in each of the following areas:
People, including IT staff and users
Hardware and equipment
Software, including in-house development as well as purchases from vendors
Formal and informal training
Licenses and fees
Consulting expenses
Facility costs
The estimated cost of not developing the system or postponing the project
Schedule Feasibility: Schedule feasibility means that a project can be implemented in an acceptable time frame. When assessing schedule feasibility, a systems analyst must consider the interaction between time and costs. For example, speeding up a project schedule might make a project feasible, but much more expensive.
Other issues that relate to schedule feasibility include the following:
Can the company or the IT team control the factors that affect schedule feasibility?
Has management established a firm timetable for the project?
What conditions must be satisfied during the development of the system?
Will an accelerated schedule pose any risks? If so, are the risks acceptable?
Will project management techniques be available to coordinate and control the project?
Will a project manager be appointed?
