Feasibility

Feasibility

• Feasibility is the measure of how beneficial or
  practical the development of an information
  system will be to an organization.
• Feasibility analysis is the process by which
  feasibility is measured
• Four categories of Feasibility
• Operational Feasibility is a measure of how
  well the solution will work in the organization.
  It is also a measure of how people feel about the
  project.
• Technical Feasibility - is a measure of the
  practicality of a specific technical solution and
  the availability of the resources and expertise.
• Schedule feasibility is a measure how
  reasonable the project timetable is.
• Economic feasibility is a measure of the cost
  effectiveness of a project or solution.

• Operational Feasibility
• There are two aspects of operational feasibility
  to be considered
• Is the problem worth solving or will the solution
  to the problem work?
• Performance Does the system provide adequate
  throughput and response time?
• Information Does the system provide end-users and
  managers with timely, pertinent, accurate, and
  usefully formatted information.
• Economic Does the system offer adequate
  service level and capacity to reduce the costs of
  the business or increase the profits of the
  business.
• Control Does the system offer adequate
  controls to protect against fraud and to
  guarantee the accuracy and security of data and
  information?
• Efficiency Does the system make maximum use of
  available resources including people, time, flow
  of forms, minimum processing delays?
• Services Does the system provide desirable and
  reliable service to those who need it?

• How do the end-users and management feel about
  the problem(solution)?
• It is important not only to evaluate whether a
  system can work, but we must also evaluate
  whether the system will work. The following
  questions address this concern
• Does management support the system?
• How do end-user feel about their role in the new
  system
• What end-users or managers may resist or not use
  the system?
• How will the working environment of the end-users
  change?
• Technical Feasibility
• Technical feasibility addresses three major
  issues
• Is the proposed technology or solution practical?
• The technology for any defined solution is
  normally available. The question is whether that
  technology is mature enough to be easily applied
  tom our problems.
• b. Do we currently possess the necessary
  technology?
• Assuming that the solution required is
  practical, we must ourselves, is the technology
  available in our information shop. If the answer
  is no, then we must ask ourselves, can we get the
  technology?

• c. Do we possess the necessary technical
  expertise?
• We may have the technology, but that doesnt
  mean we have the skills required to properly
  apply that technology.
• Schedule Feasibility
• You need to determine whether the deadlines are
  mandatory or desirable.
• Economic Feasibility
• The bottom line in many project is economic
  feasibility.
• Concerns
• How much will the system cost?
• Development Cost
• Personnel Cost- the salaries of the system
  analysts, programmers, consultants, data entry
  personnel, operators and the like who will work
  on the project.
• Computer usage Computer time will be used for
  one or more of the following activities
  programming, testing, conversion, word
  processing, maintaining the project, loading the
  new data files, prototyping.

• Training If computer personnel or end-users
  have to be trained, the training courses may
  incur expenses.
• Supply, duplication, and equipment costs
• Cost of any new computer, equipment and
  software.
• Cost of Operating a System over its lifetime can
  be classified as fixed and variable
• Fixed Costs occur at a regular intervals but at
  relatively fixed rates.
• Lease payments and software license payments
• Prorated salaries of information systems
  operators and support personnel.
• Variable Costs occur in proportion to some usage
  factor.
• Costs of computer
• Supplies
• Prorated overhead costs

• b. What benefits will the system provide?
• Tangible Effects are those that can be easily
  quantified.
• Fewer processing error
• Decreased response time
• Increased throughput
• Elimination of job steps
• Increased sales
• Reduced credit losses
• Reduced expenses
• Intangible Benefits are those benefits believed
  to be difficult or impossible to quantify
• Improved customer goodwill
• Improved employee morale
• Better service to community
• Better decision making
